Key Drivers of Electronic Components Distributing Biz in 2021

There is always a light at the end of the tunnel! 2020 washed off many pre-determined strategies as we all became onlookers stranding to get everything normal. Moving away in a flick and determining to take the next step stronger, the electronic component distribution business certainly kept its tempo high. Meanwhile, Tony from Digi-Key believes 2021 to be a recovery year. Elaborating further, he said, “We expect to see the growth of the distribution business of all technologies across multiple industries. The major automotive players in Europe and China are already feeling the pain of not getting enough semiconductors they will need in the coming months. Cloudrelated hardware infrastructure and portable terminals remain strong, and they are well coupled by the new generation of chipsets for CPU and wireless applications supporting equipment upgrades. The continuous implementation of 5G infrastructure and related applications will trigger stable demand at least through 2022. With all governments’ money policies, research and development across industries will also be indirectly benefited. Tony indeed foresees a bright year to come! Emphasizing the prevalence of AI and IoT, Aik Hoon from Avnet said, “As Artificial intelligence (AI) becomes increasingly prevalent, it is expected to become one of the catalysts driving the electronics components industry. IoT can bring data from millions of devices but we need to apply AI to IoT data to generate insights. AI is driving both hardware and software products, from custom chips to AI neural networks. Many companies are also designing AI-specific chips.” Talking about the stay-at-home economy, Aik Hoon foresees a robust demand for gaming, laptops, servers and other devices supporting remote work and education. She said, “We have seen a huge jump in the demand for electronic component needs. In automotive, the chip-reliant industry has recovered much faster than expected but was hit hard by a global chip shortage partially as a result of the stay-at-home economy. That said, the automotive electronics market is expected to continue growing. There is also a current boom in hybrid and electric vehicles which require even more components.” Witnessing the market unpredictable, Anil from element14 cites, “The industry is expected to rebound and witness recovery in 2021. We see the automotive sector picking up pace in electric and traditional vehicles. COVID-19 has driven demand in the telecommunication industry due to remote working, online learning, home gaming, etc. With the pandemic currently showing no signs of slowing down, the telecommunication industry will continue to go strongly.” He continues, “COVID-19 has also accelerated the need for touchless technology, resulting in wireless technology such as Bluetooth and NFC becoming increasingly popular. 5G will enable different levels of innovation across multiple market segments, including healthcare, autonomous vehicles, smart cities, and industrial automation.” Sharing a report, Anil added, “The world is shifting towards

Talking about their expertise in this rapidly changing technology world, Aik Hoon affirms, “As a global technology solutions provider and a distributor, Avnet is uniquely positioned to guide businesses to use the best and most effective parts from the world’s best suppliers and also offer customers an end to end solution.” Furthermore, Aik Hoon talks about product life cycles as it gets increasingly shorter. In this scenario, she believes, “Businesses need to be quick in introducing new products to the market or risk being superseded by their competitors. Avnet has been supporting our suppliers and customers in demand creation. Our extensive ecosystem of experts supports customers at every stage of the product lifecycle. We offer design, product, marketing and supply chain expertise to help companies reduce the time, cost and complexities of bringing their products to market.” On the other hand, Tony seconds on the question elaborating, “Digi-Key can’t agree more in this area. To maximize customer innovation, Digi-Key continues to invest in enlarging our product portfolios. In the past two years, we have increased 200 franchised lines, 1,100,000 searchable parts, and 300,000 SKUs for immediate purchase. Digi-Key now offers more than 11.5 million components, with over 2.6 million in stock and available for immediate shipment, from over 1,500 quality name-brand manufacturers. All of these investments are designed to enable innovation and making parts ready-togo when customers need them.” Lastly, Anil underlines the importance of R&D, adding, “The rapid pace of innovation in electronics technology creates a constant demand for newer and faster products and applications. This demand puts a greater emphasis on R&D to keep changing their input components to suppliers having innovative and latest product roadmaps at competitive prices. Multiple alternatives will help them to mitigate losses, shortages, and cost escalations. Elaborating on disruptive technologies such as Artificial Intelligence, Nanoelectronics, IoT, Cloud computing, Advanced Robotics, 3D printing, and Wearables, Anil believes these technologies are changing the face of many OEMs' manufacturing focus. Talking about element14, he said, “element14 can offer new and expanded services as an absolute value-add to our customers in new markets at a pace never seen before.

These enable our customers to get their required components with ease, and empowering them to design and test out their ideas or prototypes much quicker.”

Demand & Supply Critical for Electronic Component Distributors?

Tony emphasizing their sales and customer-retention strategy said, “There are many reasons why customers keep coming back to Digi-Key. Two years ago, 2019 was kind of a year of correction of industry cycles and 2020 had the pandemic causing fluctuated demands, but that has not stopped Digi-Key from investing. With the additional franchised lines, searchable parts, and stock-keeping units (SKUs) for immediate delivery, Digi-Key is better equipped to support our customers for their business needs.” Whereas Aik Hoon believes “Demand far exceeds supply at present. The challenge is to gain more visibility on our customers’ forecast numbers and longer-term requirements to allow us to plan better. Even with a proper forecast, many raw materials like minerals are in shortage and are difficult to procure. But with this visibility, it will mitigate the risk and loss of business opportunities for both customers and suppliers.” Lastly considering advanced supply chains in this new normal, Anil had to say, “The impact of potential disruptions such as COVID-19 are reduced by clear communication and guidance for industries in the broader network of “essential supplies”, yet the experience of the pandemic has taught us that we need a future supply chain that is more resilient and greener, with a strong capacity for innovation, whilst satisfying required regulatory regimes and taking into consideration risk, ethics and security needs.

How different you see the strategy and our portfolio and achieve our strategic goals. programs in the semiconductor workplace when it comes to talent acquisition? . What it is like being a women-leader in a tech company. One big difference is that the semiconductor industry requires How responsibilities and strategies are drawn and specific highly specialized skills, and the availability of these evaluated on a day-to-day basis and your thoughts as global skills is very limited. The number of students studying the kinds companies move towards gender equality? of electronics or electrical engineering that we want is small Women leaders in global Tech companies are making lots of and sometimes the employed base of these skills in the industry news and will continue to make their presence felt in C-suite is very low. And, of course, with the industry boom, there is roles. It is very important and satisfying for a female leader to a high demand for the kinds of profiles we’re looking for. So, be considered for, and promoted into, roles for the capability to drive talent acquisition becomes even more challenging: and experience they bring to the table instead of for their you have to appeal to candidates with the job and the gender. Most women leaders have collected enough stories company by offering them a complete value proposition, such about their sacrifices, addressing gender bias, balancing as giving people an environment, community, opportunity work/life, and the difficult competition at work. to grow and change, to do different things and to inculcate entrepreneurial skills and an innovation mindset, while still Gender diversity will continue to be a priority as companies following guidelines and compliance with company rules and implement diversity policies and take constructive actions to norms.

as understanding that business as deep below the surface as you can. The most successful HR programs are the ones that address first, the interests of the business supported by the human capital in the company.

. How would you shape the workplace and company culture in ST? ST already has a strong culture in place as I've discovered from spending my first few months doing a lot of what I call “listening tours,” although due to Covid-19 global travel restrictions, I’m using the new way of virtual sessions. ST features a strong culture of innovation, collaboration, and a sense of belonging. These are some of the expressions that I have heard constantly and consistently from all geographical and functional parts of the ST world. So rather than focusing on changing the culture or reshaping the workplace, I think we should further strengthen the solid base we have - to create more agility, increase cross-functional collaboration, inject more inclusiveness of different people and share the diversity of our experiences. Most importantly, we need to step up our existing programs and initiatives on Diversity and Inclusivity company-wide. This I believe we have much room to expand and facilitate. As organizations are striving to become more global, digital, and transparent, they can’t overlook diversity and inclusion because employees have become more exacting in their demands for respect for diversity, inclusion, and gender equality. Today, HR is a custodian to promote diversity and inclusion among employees and this can, in turn, help companies become more efficient, innovative, and productive. Just to reiterate, ST’s Diversity & Inclusivity philosophy and practice, which says that as an organization we are convinced that diversity and inclusion bring value to our business through effective innovation, (organizational) attractiveness, engagement, and agility. Also one of our ongoing objectives is strengthening the role of women in building ST’s future. Our ambition is to create value from the diversity of our workforce by ensuring that all employees reach their highest potential in an environment that respects and harnesses the richness of our differences for both individual and collective success.

to strengthen competencies in, for example, performance management, coaching, and leadership development to boost the career development of employees. So, while in my view training and mentorship programs remain fundamental, the avenues for such programs have changed from traditional methods to using more digital tools. For us, talent retention is very challenging as this young generation is highly mobile and ambitious. So, it is imperative to have good plans & programs in place to increase employees’ interest in staying with ST as well as monitoring the effectiveness of HR initiatives implemented by our competition in the industry.

. What trends will shape Human Resource departments over the next five years? The digital world has gradually redefined the HR function. More than just the way we manage our people, it has also redefined how HR operates. From recruitment to performance management, we are seeing automated processes being used. I expect Bots will continue to take over the mundane function of sifting through applications to select the qualified few. In other words, extend the paradigm shift from human-driven to digital-driven in recruitment. AI has also begun to play a strategic role in HR functions. So that's a huge part of the change. The other area where I believe the shift will continue is that HR has to continue to up its game as a consultant in terms of know-how, competency building, agility, and flexibility to provide advice on many aspects of employees’ well-being and welfare. Here the consultations must cut across different organizations, different projects, different countries, different languages, and different cultures.

In short, while preserving the relevant aspects of traditional ways of working, we must embrace automation that will greatly enhance job productivity. Usage of AI will also enable us to address whatever is the next level of complexity for recruitment, as chatbot services have found a niche in most companies. And as far as ST is concerned, we have already started the journey and process of digitization, wherever possible and relevant. This is particularly challenging for ST where a large percentage of the employees are operating in manufacturing environments. Regardless of whatever trends will shape the . What are the qualitative and quantitative results of the future of companies and the human resources function, talent acquisition strategy and how it has changed over enhancing employees’ engagement in the company is the years? critical. The bottom line is to significantly increase employees’ Changes in the talent acquisition strategy extend beyond the engagement and satisfaction level in this ever-demanding Semiconductor industry. I think technology has also pushed and ever-changing industry we operate in. the frontier in talent harnessing, talent development, and talent retention.

Private 5G Networks

PRIVATE 5G NETWORKS 5G equips communication service providers with the ability to serve a multitude of use-cases with lightning fast connectivity, enhanced mobility, flexibility, reliability and security. The global pandemic has highlighted the importance of evolving networks and the major role digital technology plays. From smart phones to smart factories the unique combination of ultra-high speed connectivity and ultra-low latency, 5G is all set and ready to transform the communication landscape and the way we perceive it. Transforming the connected ecosystem and enabling societies to take the leap with other next generation technologies such as; Internet of Things (IoT), network slicing & machine to machine communication, 5G is pushing the boundaries of connectivity to break new ground, spurring innovation for a smarter, safer and sustainable future. With commercial 5G networks live around the globe and continue to roll out in many regions, the development of private networks over 5G — something that started in LTE — will create the infrastructure needed to expand the Industrial Internet of Things (IIoT), as well as enable greater capacity for critical radio communications, campus environments, sports venues and enterprises. Private networks generally consist of a wireless local area network (LAN) that uses 5G technologies to deliver dedicated bandwidth, providing massive connectivities to support defined automation and IOT needs. One significant driver behind the growth of private 5G networks is the release of unlicensed spectrum for industry verticals, enabling deployment

Capturing new opportunities

Generally, an enterprise turns to a private network to guarantee coverage, gain network control, ensure data security and meet performance profiles. Private networks can take several forms.

•Vol - 03 / 04

Beyond the traditional model of operator-run networks, private 5G networks can be deployed and managed by infrastructure vendors, including traditional, large infrastructure vendors, as well as suppliers with cloud and software backgrounds. Findings by ABI Research estimate that the total market value unlocked by 5G could reach $17 trillion by 2035, fueled by vertical enterprise services. Savvy CSPs are recognizing the greenfield market opportunities that can be created in enterprise markets. Not only can mobile operators lease their own spectrum to support private enterprise networks, they also can develop private wireless networks that are then sold to enterprise customers. Unlike networks that provide mobile network services to the general public, private 5G networks are deployed on the company’s premises, such as; across a campus or in a factory. Such networks have high quality of service (QoS) and security requirements, helping to isolate the network against problems that occur in the public mobile network. As such, private networks can improve performance, security, privacy and safety for the enterprise, while also making it easier for the enterprise to manage availability, maintenance and operations.

Stage for future operations

Private 5G networks that use coordinated shared spectrum will require improvements in RF planning, network design, installation, test, management and operation. As such, private network operators would be well-advised to automate workflows and service assurance. Doing so not only provides immediate benefits for existing, hardware-based 4G networks, it also sets the stage for future operation of new virtualized and cloud-native 5G networks. 5G for business 5G networks present a number of exciting opportunities; not only for mobile operators, but for enterprises as well. Yet it’s important for enterprises to consider the level of technical skill needed to set up and service a private 5G network. Ultimately, those enterprises that fully understand the benefits — and challenges — of private 5G networks will reap the rewards offered by this next-generation technology.

Private mobile networks also provide enterprises with opportunities to optimize and redefine business processes in ways that are not possible or feasible on wired and Wi-Fi networks. Already, several test cases have emerged demonstrating how private 5G and IoT networks can contribute to improvements across a range of sectors, including manufacturing, healthcare, transportation, oil and gas production, mining and utilities. For instance, Ford is building a private network to test connected cars on a private LTE/5G network located in a parking lot of its Dearborn, Michigan campus. And in the healthcare sector, Norwegian CSP Telenor is partnering with Oslo University Hospital to trial the use of 5G for remote-controlled medical procedures.

As enterprises and network operators continue developing trials for private networks, the need for service assurance and business-to-business SLA management becomes vital at every stage of development. Historically speaking, testing and service assurance has been primarily manual, reactive and time-consuming, especially in relation to service activation, change management, service quality monitoring and fault isolation.

FOCUS

Getting Your Networks Ready for the Future

It may be tempting to rest on your laurels when you finally have your IIoT networks up and running. Nonetheless, change remains the only real constant in life, and the world of industrial networking is no exception. Your IIoT network may be sufficient for your current needs—it may even be ready for your foreseeable application requirements over the next several years. But what about the next decade or more? Change is always on the horizon, and we need to be prepared. Since the early days of industrial automation, manufacturers have adopted a variety of purpose-built protocols and systems, instead of standard Ethernet technologies, for highly specialized industrial control applications. However, as the IIoT market is expected to grow at a CAGR of 24%1 by 2023, industrial networks of the future will in all likelihood be required to transmit large amounts of data between interconnected devices or collect data from remote devices. With these growing demands on the horizon, how well-prepared you are for the future of industrial networking may determine your success in tackling new challenges. This section provides three considerations to help you prepare your IIoT-ready industrial networks for the future.

> APRIL 2021

Achieve Greater Integration With Unified Infrastructure

Over the years, various devices using different industrial protocols have been deployed on industrial networks to provide diverse services. Under these circumstances, network integration usually costs more than expected or becomes more difficult to achieve. Manufacturers can either choose the status quo, that is, maintain their preexisting isolated automation networks with numerous purpose-built protocols of the past, or alternatively seek solutions to provide deterministic services and integrate these “islands of automation”. If our goal is to be ready for the growing demands on our IIoT network in the future, the choice is obviously the latter. The rule of thumb is to take potential industrial protocols into consideration and ensure you can redesign your networks in case any new demands arise in the market. Time-sensitive networking (TSN) is a set of new standards introduced by the IEEE 802.1 TSN Task Group as an advanced tool box. With TSN, you can build open, unified networks with standard Ethernet technologies that reserve flexibility for the future. Furthermore, you may consider selecting solutions offered by the key players who are advocating this new technology because they actively participate in TSN plugfests to complete the ecosystem and ensure compatibility among different vendors.

cause of problems and maintain sufficient network visibility. Control engineers often have to revert to trial and error to get the system back to normal, which is time-consuming and troublesome.

Access Anywhere to Your Remote Machines With Hassle-free Cloud Services

Cloud-based remote access offers many benefits to IIoT customers, such as reducing the traveling time and expenses of sending maintenance engineers to multiple remote sites. Furthermore, cloud-based secure remote access can provide flexible and scalable connections to meet the dynamic, changing requirements of the future. However, operational technology (OT) engineers for water and wastewater treatment plants, machine builders, and other IIoT customers may find it cumbersome to set up and maintain their own cloud servers to provide new services and applications. Indeed, considerable efforts are associated with setting up new infrastructure, even if it is in the cloud. Fortunately, OEMs and machine builders can now deliver secure cloud-based services and remote access to their customers without having to maintain their own cloud servers. One key issue you should definitely scrutinize is the cloud server license scheme. Often, upfront costs may seem low for limited server hosts. However, these apparent cost savings on server hosts may actually make your project uneconomical due to a limited scale of connections. Secondly, you may also need to consider central management capabilities in order to flexibly expand remote connections in the future. With this said, carefully weigh the costs and benefits of incorporating secure remote access to your industrial networks. Always select solutions that can eliminate the hassles mentioned and help you focus on delivering more value and benefits to your customers.

Therefore, in order to facilitate and manage growing industrial networks, network operators need an integrated network management software to make more informed decisions throughout network deployment, maintenance, and diagnostics. In addition, as your systems continue to grow, you will need to pay attention to a number of network integration concerns. First, only managing industrial networks in local control centers may not be feasible three or five year later, especially when existing systems need to be integrated with new ones. It is therefore important to use network management software with integration interfaces, such as OPC DA tags for SCADA system integration or RESTful APIs for external web services. Furthermore, an interface to facilitate third-party software integration is also a key criteria to ensuring future flexibility.

As a pioneering expert in industrial networking, Moxa provides a number of innovative technologies and solutions, such as secure cloud-based remote access and a network management tool, that already satisfy the above three factors to help you accelerate your network readiness for future IIoT applications.

You may have seen the following scene in a movie or photograph in the news. The control room of a metro system has a group of monitors showing the current status of each metro station in the system, the locations of all the moving trains, and so on. Managers or operators need to quickly judge the current situation and take action according to the information aggregated on the screens in front of them. This visibility helps them keep everything under control. When complexity increases with greater connectivity on industrial networks, it can become very difficult to identify the root

YOUR JOURNEY TO DEVELOPING A SUCCESSFUL CELLULAR IOT DEVICE

Lavi Semel

CTO|Sony Semiconductor Israel There are many hurdles to overcome on the path to developing a successful cellular IoT device.

Today, the IoT device and smartphone ecosystems are worlds apart

The cellular IoT market is very different from the smart phone market. With varying requirements & challenges, there is no one size fits all. KPIs such as battery life, size, latency, location accuracy and radio conditions all change according to use case. The fact there is no human access for many of the use cases, leads to challenges of reliability, monitoring, security, and battery life.

> APRIL 2021

•Vol - 03 / 04

What are the main challenges of Cellular IoT?

The main challenges to cellular IoT relate to the lack of physical access, and the need to sustain (sometimes) extreme radio & ambient conditions for a very long time. How can we ensure that radio conditions will remain good enough for 15 years? Would the network coverage remain the same? At what cost? How do we monitor, debug or upgrade the devices? Are there long-term (e.g. seasonal) implications on device behavior & power consumption? Global connectivity challenges – With smartphones, there is human access involved, rechargeable batteries, and no issues with connectivity. Users can select which networks to search and lock on to, and when to do so. By contrast, a cellular IoT device must autonomously decide when to search for a network and which to connect to – based on low data-connectivity costs, and ‘good enough’ coverage. In addition, the need to support more than one RAT (radio access technology, e.g. NB-IoT and CAT-M and sometimes also 2G) doesn’t make it easier. The limited /out of coverage problem is much more severe than with broadband. Since the device is static, has one antenna, and with limited bandwidth, it is sensitive to coverage and interference. Battery life is sometimes the most important KPI, yet it is very difficult to predict power consumption in a cellular environment. It is affected by many factors, including; chipset, wireless conditions, network parameters & application. Power consumption may change drastically between carriers and within the same carrier (between eNB vendors). Reducing the device’s size and cost is another challenge. Manufacturers need to look at the whole BOM structure. A high level of integration reduces costs, eases development and reduces size. There are also many security challenges. Aggressive cost targets impact memory sizes, CPU performance, certification and the production process. Devices sleep most of the time and connection is not maintained. There is a strict limit on the amount of information that can be communicated. Legacy protocols may be inefficient and power-hungry.

Top Things to Consider When Building a Cellular-Based IoT Device

•Vol - 03 / 04

Below are a few tips on what to pay attention to when building a cellular-based IoT device.

Let’s start with the obvious:

1. Target battery life: First we need to define the battery lifetime, and its probability. Meaning, do we want to target the 90%-tile, 95%-tile, or the average power consumption of all devices? 2. Transmission profiles and message sizes: We need to take security into account. In some cases, a 50B packet becomes the negligible part when security is involved…. 3. Reachability (i.e. PSM or eDRX): Do we need the device to be reachable? And if so, what is the maximal latency? 4. Device conditions – stationary – and if so, where is it located? Mobile? And if so, what is the mobility profile? Followed by the less obvious…. 5. Radio technology – NB-IoT or CAT-M? The industry has developed two standards for radio technology – NB-IoT and CAT-M, with quite a large overlap between them. NB-IoT is targeted for very low data rate applications, usually non-TCP, batch-communication, and focused on stationary devices, such as water meters. CAT-M is targeted for higher data throughputs, mobility and voice. There is a myth that NBIoT power consumption is lower than CAT-M. This is not always the case. Also, network coverage is not constant, especially if the device is deployed for years. A device deployed for over 2 years in the field might need an upgrade. Doing this over NB-IoT is very challenging, as throughput is low. Therefore, a dual-mode device gives you peace of mind. You enjoy both worlds, at a higher cost (which could pay off, at the end). 6. Power consumption: Networks today are not optimized for edge IoT devices, as they are tuned to smartphones. This leads to issues with SIM power consumption, network timers, C-DRX and scheduling parameters. Close discussions between network operators and chipset/module suppliers could overcome some of these challenges. 7. Transport and Application Protocols: HTTPs is not relevant for IoT devices with battery/data connectivity constraints. MQTT is better, but still not efficient. COAPs (used by LWM2M) is the most (standard-based) efficient protocol. 8. Addressing network coverage: Firstly, optimize your network scanning parameters. Then, monitor battery life, integrate a FOTA solution, design a robust connection manager. Finally, test extensively in the field. 9. Positioning technologies: In terms of GNSS, in many cases the need is for occasional fixes (non-tracking mode). For cellularbased positioning, NB-IoT/CAT-M networks are new and base station databases are still immature. A multi-mode modem (as opposed to single-RAT) can be used to close this gap. Work with a trusted cellular IoT partner As you can see so far, designing a cellular IoT device is very challenging, and you need an experienced partner. As a leading provider of Cellular IoT chipsets, targeting all IoT markets and all relevant use cases, Sony Semiconductor Israel are here to help you achieve your goals.

Practical EMI Control in a Power Component Design Space

-David Bourner

Vicor

Abstract

Comments on the Model

Managing conducted emissions from concept through implementation

Implementing a system with such products involves introducing measures that the OEM should provide in applications literature. Module self-noise can be reduced with the introduction of suitable external components that are selected and arranged in a board layout designed to introduce minimal parasitics. The components will interact with the printed circuit layout, which means that noise performance is not something that can be automatically guaranteed. In almost every case that such provisions are offered, there will be reference made to engineering standards for CE (conducted emissions) such as CISPR22 or EN61000-4-6. These two standards contain clear definitions and detailed test arrangements that can be used to authenticate a power system’s emission and susceptibility characteristics.

The control of electromagnetic interference (EMI) within switched-mode power systems is a perennial topic. This article attempts to address the notion of control of conducted emissions in the context of applying Vicor Power Components in a customer application. Vicor has developed quasi-resonant topologies that mitigate noise to a great extent by design. Although there are significant noise reductions to be had using resonant topologies in SMPS, no converter is ever noise-free. Applying power modules in a way to assure compliance with CE engineering standards can often prevent unforeseen, costly delays in bringing products to market.

Introduction Conducted emissions control must be a consideration at the outset of a power system design, made well before final integration with other parts of a complete application. The noise mitigation schemes used must be developed alongside the power and signal processing pathways. The implementation of the system should be routinely subject to a series of prequalification tests, which although subjective, quickly bear results which indicate whether or not the final product will be adequately arranged for successful qualification outcomes. We look for minimal emissions that are below those levels that represent adequate performance.

Model of an embedded power component

The block diagram shown in Figure 1 is the author’s attempt to show all the features of a power system that address aspects that go beyond a simple DC input / output power specification. Identifying power support functions in this way allows us to be able to look at tradeoffs and interactions between these various functions. Knowledge of interactions between required functions allows the designer to adopt a design sequence that effectively addresses all aspects of performance of the finalized design. Figure 1 Generic system block diagram for a switching power system. DC power flow on the busses are represented with bold arrows. The DC-DC converter is generally arranged with galvanically-isolated input and output power ports

> APRIL 2021

In the context of noise, analog and digital systems are thought of respectively as receivers and transmitters of electrical noise. Switched-mode power converters present a mixed-mode environment. Controllers, be they digital or analog in nature, are set alongside switched power devices. Power components are modular: to a great extent the OEM (original engineering manufacturer) will have taken great pains to mitigate the effect of noise sources internal to the module, sometimes with mixed results. If not countered, self-noise of a power module is often sufficient to affect signaling affecting control of power within the component.

CE standards focus on conducted electrical noise that propagates to the input power source. Noise appearing at the output side of the system can also be attenuated, with either CM (common-mode) or DM (differential-mode) filtering or a combination of the two, just as for input-source-terminated CE. It can be argued that using power components facilitates noise control design in the integrated application. Although it is generally not possible to integrate all the suppression elements in a power component, the manufacturer will recommend the minimum effective external measures required in an optimal board layout. Given the nature of the varied types of applications being worked on by customers, applications engineers at the OEM can often be called upon to determine adequacy of current noise control strategies and suggest ways to suppress noise. This paper illustrates such an example.

Applying the Model

To illustrate an important interaction example using Figure 1, the inductance of the input power bus and the capacitors situated at the input port of the DC-DC converter (be they part of the hold-up or the filtering function) interact with the dynamic (negative) input impedance the converter presents. This introduces the prospect of input power bus instability.

•Vol - 03 / 04

Clearly, the choice of the hold-up capacitors with their attendant ESR is critical. These components, along with necessary surge and transient protection elements, impact the differential filtering of conducted noise travelling from the DC-DC converter’s input port to the source.

[b]

Besides DM noise, there are CM noise currents emanating from each of the converter’s input and output ports. Controlling such noise mandates the use of highly localized commonmode filtering components. These components will offer HF currents very small loops which are formed going from the power terminal, back through the coupling capacitance, afforded by a specially devised shield plane, back into the converter. Figure 2 shows the equivalent circuit of the DC-DC converter expressed in noise terms, as input-referenced noise current sources with X and Y capacitors set in place.

Once a zero-energy input profile has been secured and collected, data should be developed for a signal with known characteristics. This test data set will be used as a background template which can be used to assess noise sources associated with the application’s CE noise profile. With the veracity of the oscilloscope instrument and its coaxial probe established, it is now possible to exploit featured FFT processing running on the wideband oscilloscope as a rapid indicator of the conducted noise signal spectrum. It is easy to quickly establish read-back of the effectiveness of differing arrangements of CM and DM filtering and to iterate on topologies and discrete component selections for CE control.

Example of noise-control assessment

The block diagram in Figure 3 shows a system that was set up and augmented using networks of CE control elements. Some experimentation on component technology options and optimal placement of component networks (such as for the set ups shown in Figures 4 and 5) carried out to maximize noise control. At the completion of the iterative phase of establishing and testing noise control arrangements highlighted with Figures 6 through 9 inclusive, the customer had a full qualification test done on their previously non-compliant target system, modified in accordance with the measures outlined. It was established that the CE noise profile of the system was robustly attained with a good margin to spare. [h]

Figure 2 Input-power-port noise equivalent circuit of a DC-DC converter expressed with differential and CM noise current sources, along with noise-suppression X and Y capacitors, installed and connected to an underlying shield plane which offers HF capacitive coupling (Cs1, Cs2 shown as lumped equivalents) back to the source at low impedance.

Noise-control development strategy

A full qualification test is expensive and time-consuming. This process should only be carried out once, at the preproduction stage of development, before freezing the design for production. In the meantime, many simpler tests can be performed using equipment that is accessible to most designers and technicians working on hardware in a laboratory setting. It will be possible to set up and tailor noise control networks so as to minimize noise. This is often an iterative process, based on engineering intuition and a detailed understanding of parasitics in the layout, possibly exploiting them to aid in noise control. [h] Test references should be established at the outset. It is important to run some “zerosignal” tests to establish the instrumentation’s noise floor and to establish whether there are other noise sources that unexpectedly contribute energy to the system. These sources, if present, need to be noted; if it is possible to eliminate them with modest measures, then a small investment in shielding and grounding of the lab bench may be in order.

Reach of 5G in Cybersecurity As 5G has started making its marks in every sphere of today’s technology, it has enabled society to take the leap towards a smarter, safer and sustainable future.

Related to the increasing stress of secure network with the advent of new technology, the IEEE experts have shared their insights on the scope of 5G in terms of cybersecurity. The Ericsson Mobility Report 2020 shows how the impact of Covid19 has led to the network’s crucial role in society. The report expects the global number of 5G subscriptions to top 2.8 billion by the end of 2025. In India, 5G is expected to represent around 18 percent of mobile subscriptions at the end of 2025. It also states that in India, the projected value of the 5G-enabled digitalization revenues will be approximately USD 17 billion by 2030. With 5G being a platform for innovation it will enable the development of new services for consumers, enterprises, and industry, including large-scale IoT use cases.

BUT WHAT EXACTLY IS 5G?

When we spoke with Dorothy Stanley, IEEE Member and Chair of the IEEE 802.11 Working Group, she pointed out that confusion stems from the term ‘5G’ being used to refer to several ideas interchangeably: “Is 5G a vision? A set of services and data rates that are a goal to be accomplished, requiring multiple technologies? Or something that’s tied only to cellular carriers and what they can deliver?” Some experts are most focused on the mixed nature of the technology. Babak Beheshti, IEEE Member and Interim Dean, College of Engineering and Computing Sciences, New York Institute of Technology, for example: “The very design philosophy of 5G is based on network heterogeneity. This means that the network can be a combination of technologies such as Wi-Fi and LTE.”

That will be coupled with a globally unique subscriber permanent identifier (SUPI) for each user. Beheshti: “The SUPI is never broadcast over the air during connection establishment for a mobile device, which can help prevent the hijacking of a mobile’s identity. 3G and 4G networks are inferior in this respect.” For Stanley, top of mind is “The latest security solution, Wi-Fi CERTIFIED Easy Connect. You scan the QR code, and that bootstraps a protocol exchange that gets you on the network securely, so your traffic over the wireless link will not be snipped.” Since IoT devices don’t often have robust user interfaces, using a QR code lets manufacturers create security protocols that can be operated without the use of a keyboard, Stanley says. “The QR code is just a way to encode data. You’re encoding a public key that then can be used to establish and bootstrap trust. Only the peer device that has the private key can decode that.” So upcoming security technologies are promising.

WHAT CAN CONSUMERS DO TO MAKE SURE THEIR CURRENT IoT SETUPS ARE SECURE?

For Kayne McGladrey, IEEE Member and Director of Security and Information Technology at Pensar Development, “Consumers should use the ‘guest’ network of their home Wi-Fi routers as a dedicated network for IoT devices, so if one of those devices were compromised, the threat actor can’t easily pivot to more valuable data.” That’s the case for newer devices, he says. “For older, cheap, IP-based security cameras and digital video recorders (DVRs), the easiest way to secure them is to recycle them responsibly as there often are no security updates available.”

Therefore, what 5G means depends on the context of the discussion, but it’s likely to include a combination of technologies.

The ability to update devices over their lifetime is essential to security, and should factor into buying decisions, he says.

This heterogeneity makes security more complex. However, there are already some exciting developments in the pipeline for 5G and IoT device security.

Han Guangjie, IEEE Senior Member and professor at Hohai University, seconds this point: “Check and update the IoT device firmware. If IoT devices have exploitable vulnerabilities, manufacturers often identify and fix problems before the hacker can access the device’s environment.”

“According to T-Mobile US, 4G information being carried across mobile networks was not always encrypted. In 5G, end-to-end encryption is intended to provide much stronger safeguards for data privacy,” Beheshti says.

PAPER

NTC Temperature Control for IGBT and Power MOSFET Modules Temperature control is one of the key factors for a MOSFET or IGBT power module to work efficiently. Although some MOSFETs are equipped with an internal temperature sensor (body diode), there are other ways to monitor and control temperature. A semiconductor silicon PTC resistor can be used with well-defined current control or a Pt- or Ni-based resistance temperature detector (RTD) with moderately low resistance values and more linear performance. Whether the sensor is an SMD, a wire bonded die, or even a sintered die, an NTC thermistor remains the most sensitive and versatile temperature sensor. When designed properly, it will ensure the proper derating and eventual shutdown of the module in case of overheating or excessive external temperature. In this article we will focus on a bondable NTC die and adopt the path of analog electronic simulation to show how fundamentally a derating and a shutdown can be operated in a power module. Why analog? It’s the best way to simplify things and illustrate the different phenomena in a visual way. It’s also ideal for developing an intuitive application. The last motivation is pecuniary: we will develop a simulation within the limits of a free software (LTspice), while other design tools would possibly allow for more sophisticated designs. So, let’s take the LTspice design in Figure 1, which is a simple boost converter design. However, thanks to the versatility of LTspice, the IGBT and the diode models have been replaced with thermal models, where the heat fluxes are explicitly represented with an output pin, allowing them to be connected to a thermal circuit (the heatsink, for example). We will here use a simple RC circuit (in the real world, the designer would need to carefully define the Zth model as a Cauer or a Foster model). Figure 1

Alain Stas Bruno Van Beneden Vishay NLR Product Marketing temperature to control). This temperature is input into an NTC model (Vishay wire bondable die NTCC200E4203_T). The NTC signal is used via a Wheatstone bridge, compared to a threshold, amplified, and compared to a sawtooth signal (Vsaw). The final output Vsw is the pulse signal applied at the gate of the IGBT. Under the temperature threshold defined by the Rlim resistor value, we apply a 100 % full duty cycle pulse at the IGBT’s gate. When there is overheating — produced by the IGBT and the diode — cumulated with the ambient temperature (the voltage at the node Tamb in the thermal circuit), the duty cycle is reduced and the output / input ratio of the buck converter (Vout / Vcc) will be reduced. This produces less heat and the temperature begins to stabilize. At the limit above a certain temperature, this ratio must be reduced to 1. In order to perform a simulation within a reasonable time, we must scale down the thermal capacity of the heatsink. Thermal increases can take minutes or even hours, and we want to visualize them within a very short time. Here are the results of the simulation: in each figure, the results are shown with or without temperature derating (in order to eliminate the temperature control, the Rlim value is taken as very low). Figure 2

During the converter’s operation, the heat flux results in a hot spot (the voltage at the node Tsyst in this case, which is the

In Figure 8, we visualize the sum of the heat-power produced by the IGBT’s switching (I(V6) expressed in W), together with temperature (V(Tsyst) expressed in degrees Celsius) increase in time. Figure 7

In Figure 2, you will notice the usual oscillating, non-optimized behavior of a boost converter during the first 20 ms. The temperature Tsyst (Figure 4) begins to increase, and then when the ambient temperature increases, the derating Vout / Vcc begins when the Tsyst reaches 90 °C. Every further increase of the ambient temperature decreases the duty cycle until the total deactivation of the boost converter. At 110 °C, the derating is maximum. Without temperature protection, Tsyst can reach 160 °C to 170 °C (Figure 4). In real power modules, peak die temperatures could reach 200 °C or more. The voltages Vsense, Vntc, and Vlim are shown in Figure 3. The variation of the duty cycle is also illustrated at different times in Figures 5 and 6. Of course, all the thresholds are scalable and the switch threshold can be adapted accordingly. Figure 5

Going further into more complex simulations, we can also try to reproduce a full-bridge IGBT module (as shown in Figure 7). This circuit produces a 50 Hz sinusoidal current through an inductive load, with an IGBT switching at 30 kHz. The gate driver stimulation circuit will deliver a constant frequency up to 125 °C and will reduce the duty cycle in order to mitigate the IGBT losses above this temperature.

Figure 6

The produced current is also shown in the lower pane of Figure 8. Figure 8

Without entering into the details, it is possible to mitigate the temperature increase (Figure 8 lower pane, red curves) in time by playing into the modulation parameters: a reduction of switching duty time will reduce the heat production, but will also result in a less sinusoidal signal. We will not go further in the details of this case, but we hope to have shown with the provided examples that LTspice circuit simulations with NTC thermistors can be pushed very far and can help a MOSFET / IGBT power module design engineer to develop their intuition about their circuit, and help them to mitigate the crucial thermal aspects related to circuit protection.

Forty years of Know-How

How Infineon shapes power for growth through MOSFET innovation Ashita Mirchandani

Lead Principal – Device Design and Technology Development and Bastian Lang| Product Marketing Manager at Infineon Technologies

Our world has experienced dramatic change over the past 50 years. New economic, social and technological trends have emerged significantly impacting our way of life in different ways. Regardless of the way and degree to which the world has been changing, one thing remains: technology plays a crucial role in it. Whether we think about electro mobility, internet of things, artificial intelligence, connectivity or 5G, all are heavily technology-driven innovations of today and tomorrow. These new application areas not only have profound implications for our lives, but also for underlying design requirements. Design engineers face new challenges in their jobs every day: adapting new power architectures and increased bus voltages, needing more power in small form factors, demanding higher levels of power density and energy efficiency. Looking at the value chain behind the solutions that respond to these challenges, it all comes down to the tiniest detail: the microchip. System performance (including reliability aspects) hinges on the selection of the right power switches.

At the forefront of key power semiconductor innovations With more than 40 years of experience in power MOSFET innovation, Infineon has led the way in solving the challenges design engineers face on a daily basis while helping engineers achieve their targets. Although these targets may have changed over the years, the innovative spirit behind Infineon’s product offering has persisted – from device design, technology-, package- and product development through manufacturing. Looking at the evolution of MOSFETs in the industry, numerous advancements in MOSFET technology have enabled the applications and trends that have become an indispensable part of our lives. Consider the introduction of the first hexagonal topology MOSFETs in 1979 or the new generation of MOSFET technology launched in 1995 which was based on an advanced four-mask process utilizing innovative self-alignment features to improve manufacturing precision and increase yields. That process enabled MOSFETs to be manufactured with a low cycle time (compared with requirements for the six-step process) and allowed junction depths up to 40 percent smaller than conventional processes thereby greatly reducing the transistor junction resistance while increasing ruggedness. Shortly after these technological developments, the world’s first FETKY product was introduced integrating the MOSFET and a Schottky diode into a single package reducing form factor and losses in DC-DC applications. Later, in 1999, leveraging manufacturing expertise, a stripe planar technology with a

> APRIL 2021

fully self-aligned manufacturing process that featured high density planar structure providing extremely low on-resistance, excellent high-frequency operation, industry-best ruggedness and excellent manufacturing cycle time was introduced. The same year, a family of MOSFETs with the industry's highest cell density and lowest RDS(on) trench MOSFETs was also introduced. That technology focused on the latest products for handsets, laptop computers and a variety of other portable electronic devices, paving the way for ever-better performing products in the market. In 2000, the first family of OptiMOS™ MOSFET technology featuring ultra-low switching losses for high efficiency to help designers increase power density was launched. The OptiMOS™ family has evolved throughout the years and is now in its sixth generation. OptiMOS™ products offer an impressive reduction in RDS(on) combined with superior switching performance. The OptiMOS™ family is optimized for a variety of applications and circuits, such as synchronous rectification in switched mode power supplies (SMPS) in servers, desktop PCs, wireless chargers, quick chargers, and OR-ing circuits. Additionally, in 2012, the StrongIRFET™ family of MOSFETs optimized for low RDS(on) and high current capability – making them the ideal choice for low frequency applications requiring performance and ruggedness – was also introduced to the market.

Figure 1 Technology development and product family positioning of Infineon’s 12-300 V power MOSFET offering Packaging innovation has also been at the heart of Infineon MOSFET development. In 1993, the SOT-223 was introduced as the first surface mount power MOSFET in the industry. In 2002, the DirectFETTM power package was introduced as a proprietary

•Vol - 03 / 04

surface mount package featuring a new interconnection methodology with radical gains in both conduction and thermal efficiencies. In 2013, the widely utilized TO-Leadless package that allows for high current capability in a reduced footprint compared to a traditional D2PAK was introduced. Most recently, Infineon has launched a family of OptiMOS™ power MOSFET devices in a PQFN 3.3 x 3.3 Source-Down package with a flipped die inside to allow for improved thermal performance and reduced RDS(on).

benefits of the innovative package include: – 30 percent lower RDS(on), decreasing I²R losses – Lower package-related parasitics, reducing the FOM and leading to lower switching losses – Lower Rthjc, optimizing the distribution of the generated heat from the package – Thermal pad located on the source pin, enabling optimized layouts where the large GND area can be utilized as a heatsink To compare the performance benefits, two versions of an 8:1 hybrid switched-capacitor (HSC) converter board were examined. One is based on a standard Drain-Down device (BSZ011NE2LS5I) and the other on the new Source-Down device (IQE006NE2LM5). Figure 2 shows the thermal performance of the devices. With the traditional package a hot-spot can be observed (Figure 3a) that is eliminated with the use of the new Source-Down package (Figure 3b). The surface temperature of the MOSFET is significantly improved, showing a 9°C difference compared to the Drain-Down device. Figure 4 illustrates the efficiency comparison (including auxiliary losses). The higher efficiency of the system featuring the new Source-Down device leads to a significant increase in power density as well.

Let’s take a closer look at what benefits packaging innovations can bring to an application.

Innovating on chip-level for system performance

The chosen application example is artificial intelligence. Power management – more specifically, the power density of the power converters fueling the processors and ASICs in a system – is one of the biggest challenges designers face in enabling artificial intelligence and keeping up with the calculation and storage needs in the cloud. With the introduction of 48 V bus voltage, some additional power conversion is introduced into the power chain. This conversion has to be done close to the payload to avoid transmission losses and benefit from the higher bus voltage. With Infineon’s Hybrid Switched Capacitor (HSC) resonant DC-DC converter, innovation is at the system-level by utilizing Infineon’s newest Source-Down OptiMOS™ power MOSFETs. This new topology shows great potential to offer higher power density and efficiency levels than the current solution. Combined with Infineon’s new Source-Down product portfolio, this solution can be optimized from the ground up, component-level innovation with the system in mind. Let’s take a look at how this is done. Addressing power density challenges requires innovation at the component level with advancements in resonant topologies. With the introduction of Infineon’s Source-Down package technology, the IQE006NE2LM5 further enhances electrical and thermal performance, enabling the power density needed in modern datacenter applications. The main

For more than 40 years, Infineon power MOSFET innovation has proven that optimization at the component level brings significant system-level performance advantages and contributes to an easier, safer and greener future.

EV > COGOS, Altigreen to Deploy 1000 EVs in Its Fleet

Porsche Increases Stake in EV Maker Rimac

COGOS has partnered with Altigreen by deploying 1000 EVs in its fleet, a step to further strengthen its commitment towards electric mobility in the country. This partnership has materialized at an opportune time as the budget 2021 and the later impositions of green tax and new scrap policy extensively showed the government's intent to enhance EV adoption in India.

Rimac Automobili has received another investment from Porsche AG. Porsche said that it has invested €70 million ($83.3 million) into Rimac, a move that increases its stake from 15% to 24%. This is the third time Porsche has invested in Rimac. Porsche is most interested in Rimac’s development of components, according to comments made by Lutz Meschke, the deputy chairman of Porsche AG’s executive board.

COGOS would initially operate across all metros in India including Bangalore, New Delhi, Mumbai, Pune, Hyderabad, and Kolkata, before expanding to Tier 1 and 2 cities. COGOS plans to bring in at least 30% of its revenue from green technologies by 2023 and this agreement paves the path to reach its sustainable goals. COGOS will provide multiple offerings including a scalable, sustainable, and cost-efficient solution to its end users.

Porsche has already placed its first orders with Rimac for the development of highly innovative series components, according to Meschke. Despite its continued investments, Porsche said it doesn’t have a controlling stake in Rimac.

In Phase 1, COGOS is focused on deploying a fleet of 1,000 vehicles. The initial focus will be on three-wheeler cargo applications and the company will primarily utilize Altigreen three and four-wheelers that are custom-designed with highquality components & custom-built software that delivers high energy-efficiency and long life.

The German automaker made its first investment into Rimac in 2018. Porsche increased its equity stake into Rimac in September 2019. A few months earlier, Hyundai Motor Company and Kia Motors jointly invested €80 million ($90 million at the time) into Rimac. However, Rimac does more than produce hypercars. The company, which employs 1,000 people, also focuses on battery technology within the high-voltage segment, engineers and manufactures electric powertrains and develops digital interfaces between humans and machines.

TECH PAPER

Industry Set to Test the Six Nines Capability of New 5G Mobile Technology

Brendan O’Dowd

General Manager, Industrial Automation| ANALOG DEVICES

Until the launch of 5G, every previous generation of mobile phone technology was primarily intended to improve the operation of the handset. First-generation mobile phone networks were analog systems that provided just enough bandwidth for voice calls. Introduced in the early 1990s, 2G was the first digital mobile technology, while 3G in the late 1990s made it possible for handsets to carry email messages and provide rudimentary access to web pages. It was not until the adoption of 4G technology in 2008 that real smartphone capability was enabled: 4G mobile broadband led to the development of smartphone apps, the proliferation of multimedia and streaming services, and access to high speed internet on-the-go. The recent installation of 5G networks marks the first time that a new generation of mobile technology has been built around the needs of machines and systems rather than handset users. The telecommunications industry’s plan for 5G envisaged technical breakthroughs in three main parameters: ► Latency, reliability, and determinism ► Connection density ► Bandwidth and the speed of data transfer The reason for enhancing performance in these parameters was to enable real-time monitoring and control of dense concentrations of devices communicating concurrently. In a smart city scenario, for instance, 5G is expected to enable real-time information about the location of available on-street parking spaces to be displayed in the navigation system of cars in the vicinity. Such a smart parking system will require the simultaneous connection of thousands of proximity sensors or cameras and thousands of cars in a small area, continually transferring real-time data about space availability and location. The requirement of this and other applications for latency,

> APRIL 2021

density, and bandwidth is met by three technology enhancements embodied in the 5G standard specifications: ► Ultra-reliable low latency communication (URLLC) for real time-control systems ► Enhanced mobile broadband (eMBB) to support new bandwidth-dependent use cases, including augmented and virtual reality ► E n h a n c e d / m a s s i v e m a c h i n e t y p e communications (eMTC) for low power, wide area wireless networking These 5G technology features make it capable of supporting the requirements of factory control systems for real-time determinism and six nines (99.9999%) availability. Yet the real-world experience of most mobile handset users accessing 2G, 3G, or 4G networks still involves black spots where coverage is weak or nonexistent, and of occasional and unpredictable dropped connections. So is there a realistic prospect that mobile phone technology will be used to connect mission-critical, time-sensitive industrial machines?

Replacement of the Mature 4 mA to 20 mA Technology

For all the hype around state-of-the-art 5G technology, the reality is that most process equipment installations today include a provision for control via mature wired 4 mA to 20 mA links—a proven, dependable technology that dates back to the 1950s. This speaks to industry’s need for certainty and the avoidance of risk when implementing mission- or safetycritical control systems. But the tides of change cannot be beaten back forever, and innovations in the way factories operate give control system designers good reason to evaluate alternatives to 4 mA to 20 mA technology. As Industry 4.0 and other global phenomena accelerate the pace at which factory operations evolve, two trends are driving the introduction of new networking technologies: the introduction of autonomous mobile machinery and the development of more flexible manufacturing facilities to meet growing consumer demand for personalized or configured products. In factory and warehouse settings, the use of autonomous guided vehicles (AGVs), cobots, and other types of autonomous mobile devices offer an effective way to increase efficiency and productivity. As automated equipment takes on the burden of performing repetitive and mundane tasks, workers are freed to transfer to higher value and more interesting factory operations that machines cannot perform.

•Vol - 03 / 04

The new generation of autonomous mobile devices such as AGVs requires a wireless communications connection that offers low latency for real-time control, high bandwidth to carry the signals from multiple sensors such as LIDAR scanners and video cameras, and high immunity to interference—the hallmarks of 5G mobile networks. When factory operators replace wired with wireless connections, they also gain the flexibility to quickly reconfigure factory equipment to meet new or varied demands from consumers. The rise of e-commerce raised expectations from consumers for near-instant delivery of ordered products and for the ability to choose from a wider range of product options than ever before. The ability to move production or process equipment more quickly and easily is growing in value. A fixed, wired communications infrastructure is less flexible than a wireless network to which equipment can connect from any location. Wireless networks also reduce the cost, inconvenience, and technical difficulty involved in installing communications cabling. Over the long-term, then, factory operators are open to the benefits of wireless control capability alongside established wired communications technologies. In the immediate future, however, industry must prioritize its most important requirements, which are: ► High reliability and availability ► Security ► Robustness to cope with challenging industrial operating conditions ► Ultralow latency These factors underlie the longevity of the 4 mA to 20 mA standard for factory communications. And while factory operators are looking to replace 4 mA to 20 mA technology, their focus today is on the implementation of the time sensitive networking (TSN) standard for wired Industrial Ethernet communications, rather than for anything wireless. TSN has emerged as the preferred standard for high bandwidth, wired data communications in the factory, since it offers the ideal combination of reliability, robustness, a high data transfer rate, low latency measured in microseconds, and easy integration with enterprise IT network systems. And because the TSN specification is a standard benefiting from cross-industry support, it is rapidly developing a rich ecosystem of suppliers of TSN components and systems, which includes Analog Devices.

OpenRAN: Non-Public Networks Enable the Validation of Claims Made for 5G Performance

Alongside the implementation of TSN networks, the scope for enhancing factory operations through the implementation of wireless networking is also coming under active evaluation. Some early adopters in the industrial community have already begun the work of testing, validating, and evaluating the operation of 5G networking systems inside the factory, while concurrently replacing legacy 4 mA to 20 mA systems with new TSN Ethernet networks. This validation process will find the most suitable applications for 5G technology.

•Vol - 03 / 04

So factory operators are now starting to test the innovative features of the 5G specification, such as massive MIMO capability—the use of arrays of antennas to provide multiple physical transmission paths between a transmitter and receiver. An array may be configured to form multi-antenna beams transmitting to multiple receivers. This allows the implementation of techniques such as channel hardening, beamforming, rapid channel estimation, and antenna (spatial) diversity, the effects of which are to dramatically improve reliability and reduce latency compared to 4G mobile networking. Indeed, one of the aims of the developers of the 5G standard was to enable wireless networks to achieve six nines reliability for packet delivery, comparable to that of a wired Ethernet network, and equivalent to a packet error ratio of 1:1,000,000. Latency of just 1 ms is also possible, which is well within the limit imposed by many industrial control applications. The question is, can this performance be achieved in the real-world conditions experienced inside a factory, where communications equipment might be subject to multiple sources of high amplitude radio frequency interference, transient voltage events, high temperatures, and other disturbances? In validating the real-world performance of a 5G installation, factory system designers have a choice: they can, of course, take advantage of 5G coverage provided by mobile network service providers. But the 5G standard also makes provision for the implementation of private systems, or so-called non-public networks (NPNs) that cover, for example, an industrial campus or a large factory complex. Different industrial users and use cases will favor a different choice of public or private network. The implementation of 5G networking in the factory is also facilitated by developments from mobile network operators of the OpenRAN (Open Radio Access Network) specification. This has opened the market for 5G radio and core equipment to a broader range of suppliers in addition to those which traditionally served the telecoms equipment market. This has the potential to broaden the choice of equipment available to meet the needs of use cases different from those of massmarket public network operators and to encourage the development of 5G products by suppliers that are focused on the industrial market. As a supplier of physical layer components and protocol software to manufacturers both of TSN equipment and of 5G infrastructure, Analog Devices is ideally placed to assess the prospects of each technology for implementation in industrial control systems. While the immediate future belongs to wired Industrial Ethernet technology, it is easy to imagine a future where AGVs and robots inside the factory transmit and receive time- and mission-critical data payloads via a 5G network—and the availability of 5G network coverage means that this is an actual rather than a theoretical possibility today.

We are all waiting a return to social and business normalcy after the Covid-19 vaccine is successful. Whether in a conference room, meeting room, cafeteria, or break room, all will start being used again enabling groups of people to gather to interact face-to-face. Prior to Covid-19, how many of you remember the meeting coordinator saying, "we’ve been here awhile, let's take a short break" or "I am feeling like I need a breath of fresh air"? Even working from home, how often have you found yourself taking frequent breaks to stroll around the house because you feel a bit "worn" from sitting in a closed home office?

The US084 Sensor Module (Figure 2) is available and uses the standard mikroBUS™ click format, allowing it to be used or evaluated with any MCU development kit providing a "Click" socket. Image

Build-up of carbon dioxide (CO2) and volatiles expelled by human breath in these tightly closed rooms generate, in part, "unhealthy" air quality. If we could detect the decline in a room’s air quality and "warn" people or automatically turn the ventilation up, this would be a great solution. All these rooms have one thing in common, lighting. Many of today’s new lighting systems are "connected" for ease of control for color, presence and ambient light detection. Connected lighting is expected to grow in all geographies, even expanding to older building retrofits. Since lighting modules are so pervasive, it would be logical to add a simple sensor module so they could monitor the lighting and "unhealthy" levels of gases such as CO2. Designers of a lighting system would just need to add a few extra bits of data to the already existing communications infrastructure. Renesas’ connected lighting solution, including air quality and lighting, shows a typical connected lighting block diagram (Figure 1). The sensor array contains an HS3001 for temperature and humidity, a ZMOD4410 for indoor air quality (eCO2 and TVOC gas monitoring), and an ISL29125 for monitoring ambient light and color control. We also have a ZMOD4510 outdoor air quality sensor for entry ways, streetlights, loading docks, etc. In addition, connectors are provided for optional PM2.5 sensors. Image

Sports Innovated:

The Influence of Motor Racing on Next Generation Passenger Vehicle Development With total annual viewing figures measured in the billions, motor racing represents one of the world’s most popular televised sports. It gains widespread media attention and generates huge sponsorship revenues. With many of the world’s leading automotive brands participating in some form of motorsport, it provides a valuable platform for these companies to showcase the strength of their engineering credentials. As well as being of value competitively, car manufacturers appreciate the other plus points that motorsport involvement brings in terms of contributing to their ongoing product development programs. Many of the technological wonders that were first seen on the racetrack have eventually been adopted into passenger cars - resulting in enhancements in performance, improvements in fuel economy and higher degrees of occupant safety. Key innovations that stem from this source relate to hybrid engines, in-vehicle networking, the acquisition of diagnostic data, more effective camshaft arrangements, automatic transmission systems, improvements in aerodynamics, use of advanced chassis materials and regenerative braking.

A New Era of Motorsport Endeavor

With the prevalence of electric vehicles (EVs) now starting to grow significantly, the ABB FIA Formula E World Championship race schedule is now being recognized as vital testbed for automotive ingenuity. With a very engaged and continuously

rising global fan base, its E-Prix events are helping to dispel the myth that EVs can’t be exciting. There are an array of high-profile automotive brands taking part in this competition, including MercedesEQ ®. There is, once again, huge potential for technology to crossover into mainstream cars - particularly in relation to energy recovery mechanisms or power management systems.

VP, Worldwide Solutions Engineering, ON Semiconductor

In Formula E, the format is constantly evolving - with teams needing to be able to respond accordingly. For example, the first four Formula E seasons, drivers had to change cars halfway through the race, ditching the one they had originally started with for a second fully charged car. In Formula E’s fifth season (in late 2018), this all changed. From that point onward, the cars of all competing teams needed to have the battery capacity to complete that whole race, without any substitutions. To address this change, the teams’ technical staff have had to make huge steps forward in the operational efficiencies of their vehicles, as well as boosting energy storage densities substantially.

•Vol - 03 / 04

Bringing Formula E Engineering into Real World Scenarios will, however, also be of considerable value from a charging So let’s now look at the ways in which what is happening on the racetrack will have an effect on the EVs that we will be buying in the years ahead. There are several areas where the technology developed for Formula E Generation 2 race car should have long term benefits to mass market EV designs. Here are some of the most important ones: 1. The battery technology - a key obstacle that needs to be overcome if the commercial uptake of EVs is to be accelerated is allaying consumers' worries about not being able to travel adequate distances in such vehicles before they run out of charge. Through experimentation with new battery chemistries, combined with improvements to powertrain efficiencies (both of which have been derived from work being done in Formula E race car to some extent), EV models now on the market are capable of covering over 200 miles before needing to be recharged. At the same time, comprehensive roll-out of charging infrastructure and the advent of fast charging technology are each helping to address consumers ‘range anxiety’ issues still further, by ensuring charging can be done in a quick and convenient manner. 2. The powertrain - for the powertrains in both Formula E race cars and mass market EV models the objectives are much the same. These are predominantly to maximize power transfer efficiencies as much as possible (by employing sophisticated motor algorithms, undertaking switching at faster speeds to avoid losses) and supplement battery reserves via use of kinetic energy recovery mechanisms. By successfully achieving these objectives, the rate at which the battery depletes will be slowed and the range that the vehicle can cover before needing a recharge will be expanded. The main power bus used in the majority of consumer EVs will currently have a 400 V (voltage) rating. Through the impetus provided by Formula E race cars, where higher voltage powertrains are already utilized, 800 V systems are now being developed for mass market deployment. These elevated voltage figures will not be addressable using conventional silicon power discretes. They will instead call for the incorporation of wide bandgap devices, such as those based on silicon carbide (SiC) process technology. SiC already features in the powertrains of Formula E race cars, with its elevated levels of efficiency and resilience to harsh operational conditions proving to be extremely advantageous. ON Semiconductor is playing an integral role in Formula E powertrain development. For example, it has assisted the Mercedes-EQ Formula E Team in developing ultra-efficient powertrain systems through use of superior automotive-grade power devices. The two companies have worked closely together on improving the efficiency levels at the traction inverter power stage. What has been learnt from projects like this is then subsequently being leveraged to improve consumer EV powertrain efficiencies. 3. Fast charging - migration to higher voltages is already underway within the EV mains bus - helping to increase operational efficiencies and combat potential wastage. It

perspective, allowing transmission losses to be curbed. Much as prospective EV customers have concerns about vehicle range, they are also keen to ensure that charging doesn’t present unwanted difficulties. The charging technology for the latest generation of Formula E race cars enables 4kWh worth of charge to be supplied in an interval of just 30 seconds. Such speeds won’t be achievable by consumer charging points for a very long time yet (with electrical distribution grids struggling to support this, as well as there being issues in relation to the current carrying capabilities of the charger and cabling). Nevertheless, the period taken to fully charge EVs is constantly being shortened - and this trend will continue, with incorporation of the latest wide bandgap power semiconductor devices being of paramount importance here. 4. Regenerative braking mechanisms - regenerative braking is an important aspect of Formula E race cars, as it means there are greater available energy resources that the race car can access. In a racing scenario, where hard braking is commonplace, there is clearly ample opportunity for regeneration. That said, the time taken to capture this energy during a hard brake is not long enough for it to be transferred back into the battery. Supercapacitors provide a means of temporarily storing the recovered energy, so that it can then be returned to the battery, or applied back to the motor when the race car starts to accelerate again. Inclusion of these supercapacitors is justifiable in Formula E designs, but their high price tag will preclude them from use in consumer EVs, where costs need to be kept in check. Also the brake to run ratio will be far lower in consumer EVs, and so the benefits derived will not be as great. Even so, EV manufacturers are putting a lot of engineering effort into the development of cost-effective energy recovery systems for mass market deployment.

Conclusion

The relationship between innovation in motorsport and the development of better road vehicles is still very much apparent. Formula E race cars like the Mercedes-EQ Silver Arrow 02 are now taking on the mantle as a technology drive Formula E is the global platform for OEMs designing new EV models and specifying the constituent components. The ongoing knowledge transfer that arises from it will be pivotal in enabling society’s vehicle electrification goals to be met. ON Semiconductor has been heavily involved in this knowledge transfer. The company is able to draw on the experiences it has gained at Formula E racetracks and research centers, plus the expertise it possesses in SiC and gallium nitride (GaN) technology, then apply this to EVs on our roads. In doing so DC/DC conversion can be made more efficient, plus higher voltages and faster switching speeds can be attained. Through such innovations, EVs will become a much more attractive option to the car buying public, and over time this will help to increase the proliferation of these vehicles.

. What is the role of QA in digital transformation? How QA contributes/ benefits the digital transformation objectives? Be it IT or Manufacturing, QA always gets paramount importance in any field, though it is termed differently e.g. QA, QC etc. In the digital world, we are making systems smarter, intelligent, powerful and resilient. This has led to transformation in development methodology too e.g. Waterfall to Agile, Monolithic architecture to Microservices architecture, Bare metal to Cloud, DevOps, DevSecOps and the list goes on. In digital development, there has been a huge absorption of open source into development, developers have zillions of reusable codes and frameworks available, the quality of such open source are not guaranteed unless we put them in proper testing. We are also seeing the advent of “Low Code” platforms like “Mendix & Claris” to build applications. These applications pose challenges of a different kind. This makes QA an indispensable part of digital transformation.

Five Ways to Protect Augmented Reality Wearables from Electrostatic Discharge Damage Design for connectivity, reliability, and safety using the latest circuit protection technologies and board layout strategies Those of us who wear vision correction glasses are used to seeing the world through lenses. New technologies now allow a virtual world to be layered on top of the real world that we normally see. The lenses will become displays that allow us to see the “real” world that is augmented with overlaid information and images, creating an Augmented Reality (AR). An example would be the integration of navigation into the AR glasses to allow a user to walk through town with turn-byturn instructions (visual or verbal) to help them easily get to their destination. Other examples include facial recognition, fitness tracking/health-sensing, travel assistance, business news, first-person photos and videos (Figure 1).

ESD Selection and Configuration Factors for TVS Diodes utilized in AR wearables 1. Increasingly Smaller Form Factors Today’s ESD diodes offer a variety of performance benefits for AR applications led by a small form factor (Figure 2). To optimize their future circuit designs, design engineers should follow these recommendations for the selection and configuration of ESD diode technologies.

The SP3522 Series lowcapacitance bidirectional discrete TVS diode arrays provide symmetrical ESD protection for high-speed data lines when AC signals are present. They are also designed for consumer electronics such as smartwatches, smartphones, tablets, eReaders, and fitness bands.

diodes are used in AC circuits, which may include any signal with a negative component greater than -0.7V. These circuits include analog video, audio, RF interfaces, and legacy data ports. Where possible, electronics engineers should choose unidirectional diode configurations to improve performance during negative-voltage ESD strikes. During these strikes, the clamping voltage is based on the forward bias of the diode, which is usually less than 1.0V. During a negative strike that is based on the reverse breakdown voltage, a bidirectional diode configuration provides a clamping voltage that is higher than the forward bias of a unidirectional diode. Thus, the unidirectional configuration dramatically reduces the system stress experienced during negative transients. Figure 4. The SP1020 from Littelfuse provides robust ESD protection in a very space efficient 01005 package making it ideal for applications like AR Glasses where board space is very limited.

3. Determine diode location Board-level ESD diodes at each of the IC’s pins are not required in most circuits. Instead, the circuit’s designer should determine which pins might be exposed to user-generated ESD events that occur outside of the application. If the communications or control line can be touched by the user, it becomes a possible pathway for ESD to enter the integrated circuit. Typical circuits include buttons, switches, USB, audio, and other data buses. While incrementally adding these discrete devices, it is important to reduce the size to fit 0201 or 01005 outlines to avoid using too much board space. There are also space-saving multi-channel arrays available for many wearable applications. Place the ESD device as close to the ESD ingress point as possible, which is typically defined as the connector or the I/O. 4. Consider routing of “ESD” trace To protect the IC’s pins with an ESD diode, there are several key considerations for trace routing—from I/O to ground. ESD, unlike lightning transients, does not unleash a large amount of current for a long duration of time. It is important to move the charge from the protected circuit to the ESD reference as quickly as possible to effectively handle ESD. The length of the trace are the overriding factors—from the I/O line to the ESD component and from the ESD component to ground— not the width of the trace to ground. Trace lengths should be kept as short as possible to limit parasitic inductance. This inductance results in inductive overshoot, which is a brief voltage spike that can reach hundreds of volts if the stub trace is too short. Recent package developments, include µDFN and Wafer Level Chip Scale Packages (WLCSP) utilize outlines that fit directly over the data lanes to completely eliminate the need for stub traces.

5. Understand HBM, Machine Model (MM) and Charged Device Model (CDM) definitions HBM, MM, and CDM are test models for characterizing the ESD robustness of the integrated circuits that run the portable device or wearable, including the processor, memory, and ASIC. They are used by the semiconductor supplier to ensure the robustness of the circuits during manufacturing. The current trend is for suppliers to reduce the voltage test levels since it saves die space. Additionally, most electronics manufacturers not only provide for ESD protection, they have countermeasures in place during the assembly process. If ESD protection is only becomes a consideration during assembly, then once the device reaches the consumer, the device is susceptible to ESD damage in the consumer’s environment. Without adequate ESD countermeasures built in, electronic devices will fail incrementally or catastrophically in the user’s environment. To guarantee fewer ESD related field failures and thus happy customers, electronics design engineers should select a board-level device that is robust enough to protect against intense electrical stresses yet offers the bandwidth and the electrical performance demanded by the end-user product. When evaluating ESD protection components, consider the following parameters: • Dynamic resistance: Defines the diode’s resistance to the change in state from blocker to conduit of electronic energy. This value represents how quickly the diode will clamp and divert the ESD transient pulse to ground. It helps define how efficiently the avalanche diode conducts the excess voltage and current to ground. The more vertical the I-V or TLP curve is, the more efficient the avalanche diode is, and the lower the expressed dynamic resistance. • IEC 61000-4-2 rating: Tested and confirmed during design and characterization, this rating reflects what the ESD diode is capable of withstanding repeatedly without degradation of the DC performance. Typically for this parameter, the higher the value, the better. A growing number of Littelfuse ESD diodes approach 20kV and 30kV under contact discharge conditions, which regularly exceeds industry standards for fielded electronics, nominally 8kV air discharge. • DC (Direct Current) Performance: When designing circuits that need protection, remember these important considerations: • Parasitic capacitance, • Parasitic inductance, • Surge tolerance (8/20us), and • Nominal and maximum leakage currents. The approach will vary depending upon the performance characteristics of the interfaces being protected.

2K Conformal Coatings Address Performance Challenges in the Harshest Environments

Phil Kinner

Electrolube Technical Director (Coatings Division)

Introduction

The performance requirements of coating materials continue to become ever more challenging, as electronics are subjected to ever more hostile operating environments, including higher temperatures along with increased levels of salt-spray and condensation. As OEMs try to save weight from their designs, the use of robust metal assembly housings are being replaced by less hardy designs, transferring increased performance requirements to the assembly, such as continued operation under full immersion conditions. Simultaneously, environmental legislation continues to evolve, with an emphasis on reducing solvent usage and VOC emissions. In response to these ever increasing performance challenges, a new generation of two-part 2K conformal coatings have been developed by Electrolube to provide even greater protection, compatible with the protection offered by an encapsulation resin, however, with the easy application of a coating. The 2K series of coatings have been rigorously tested in comparison to UV and silicone coatings in a variety of harsh tests, which have included thermal shock, powered salt-spray, condensation and mixed flowing gas (MFG) testing, which will be explored further in this article. Firstly, let’s examine the driving forces for using conformal coatings in harsh environments. Given that the conformal coating is often providing secondary protection (housing normally provides the main barrier properties), it is useful to consider the main threats that must be mitigated against and other unique demands caused by the long service lifetimes of the assemblies, when selecting a suitable conformal coating material for harsh environments. The vast majority of decisions to use coatings traditionally falls into one of the following 4 categories: 1. Protection against corrosion in end operating environment (Humidity, Corrosive gases, Salt-spray etc) 2. Protection against condensation in end operating environment 3. Reduction in component spacing to meet safety or design criteria 4. Tin whisker mitigation By considering the requirements of each application independently, some common themes emerge.

1 Protect against corrosion in end operating environment

Corrosion is a complicated, diffusion controlled, electrochemical process that takes place on an exposed metal surface. Despite the vast variety of potential mechanisms and causes, in the majority of cases, there are 3 requirements that must be fulfilled in order for corrosion to take place.

> APRIL 2021

1. Intrinsically electrochemically dissimilar metals (e.g. Gold/ Silver and Nickel/Tin), or the creation of an anode and cathode by application of applied bias. 2. The presence of an ionic species (usually Salts, Halides, Hydroxides etc). 3. The presence of mono-layers of condensed water to dissolve the ionic species, resulting in an electrolyte solution.

In order to prevent the possibility of corrosion, it is necessary to remove one of the pre-requisite conditions. The choice of metals is limited to those used in the solder and solder finish chemistries (which are dissimilar), and there will always be areas of potential difference due to the nature of an electronic assembly. Cleaning can help remove ionic species, but cannot prevent the re-deposition of ionic species from the operating environment. Conformal Coatings help prevent the formation of electrolytic solutions by acting as moisture barriers. Given the 3D topography of metal surfaces on a PCB, all metal surfaces need to be sufficiently well coated to prevent exposure of the metals surface to a potentially corrosive environment, in order to provide the maximum degree of protection. Small voids in the coating that expose the metal surface can actually accelerate corrosion under the right environment. The conformal coating challenge is achieving the required level of coverage on the three-dimensional, complex topography of exposed metals. In addition to perfect coverage, the coating also needs to be a good barrier against moisture and provide good adhesion to the substrate to prevent delamination. Once the coating is delaminated, moisture can eventually collect in this ‘pocket’ and form an electrolytic solution with any preexisting ionic contamination. This is the reason that cleaning prior to conformal coating is recommended, to provide a powerful synergistic elimination of two of the three pre-requisite conditions for corrosion.

2 Protect against condensation

Whenever there is a significant level of humidity, there is always the opportunity for parts of the assembly to drop beneath the dew point, resulting in the formation of condensed water on the surface of the assembly, which can significantly reduce the insulation resistance of the boards surface, resulting in the malfunction of electronics.

only real potential failure mechanism as two protruding tin whiskers meeting and forming a short, which is a statistically insignificant probability.

Whilst pure water is not a great conductor of electricity, any ionic impurities (e.g. salts from manufacturing or end use environment) will become solubilised and will form a conductive pathway, leading to corrosion as described above. Higher levels of liquid water can rapidly accelerate this process. In addition to corrosion, condensation severely tests the insulation resistance of the coating. Considering this is essentially an immersion application, water will very quickly find weak spots or voids in the coating. Whether there is no coating, or the coating is thin, the insulation provided will be negligible or less than optimal. The conductive solution can carry the current from one weak spot to another very quickly, resulting in either immediate failure, which may be reversible when the board dries out again, or which may be permanent if conductive corrosion products, dendrites (metallic filaments) or other permanent sources of current flow are deposited on the surface of the coating.

3 Reduce component spacing

Although air is normally an excellent insulator, it can begin to break down when stressed by a sufficiently high voltage (an electric field strength greater than about 3 kV/mm), becoming partially conductive. Across gaps, breakdown voltage in air is a function of separation. If the voltage is sufficiently high, complete electrical breakdown of the air will culminate in an electrical spark or an electric arc that bridges the entire gap. Conformal coatings provide additional insulation resistance and can be used to enable designers to make their designs more compact, by placing components closer together than would otherwise be possible.

4 Tin whisker mitigation

The application of conformal coating is a tin whisker mitigation strategy. Conformal coatings mitigate the risk of tin whiskers generating a short in one of three ways. a) A tin whisker eruption needs to puncture and penetrate out through the coating. Research shows that this is unlikely. b) In order to short, the protruding tin whisker must either: a. meet another protruding tin whisker from an alternative polarity b. penetrate back through the coating at a place of opposite polarity to create a short. All of these situations for forming a tin-whisker short are unlikely (but not impossible) events. Research and modelling show that as long as you have adequate coverage and thickness of conformal coating on conductive surfaces leads, it is unlikely for tin whiskers to penetrate through the coating once, and almost impossible to do so twice. That leaves the

•Vol - 03 / 04

By considering these 4 case scenarios, it should be clear that the coverage of the applied conformal coating must be as close to perfect as possible. In addition, it should be recognised that the greater the thickness of conformal coating achieved, the greater the protection will be from the environment. For conventional liquid-applied materials and application processes, achieving good coverage and thickness has been shown to be problematic in the IPC’s ‘state of the industry assessment’, with literally thousands of cross-sections analysed, showing zero (for all practical considerations) coverage on many common component leads and bodies for all material/ process combinations.

MATERIALS

thermal shock resistance, cycle-time etc.) a new coating concept was developed to reliably meet these increased performance demands.

The Two-Component (2K) Approach

Electrolube developed the 2K conformal coatings series by way of providing a solution to common problems faced by manufacturers with performance issues of current coatings in harsh environments. The 2K series of coatings is significantly different in its protective capabilities due to its capacity for greater coating thickness and enhanced edge coverage. 2K coatings are VOC-free, fast-curing, high performance two-part conformal coatings that provide a solvent-free alternative to both UV and silicone materials, require less capital investment than UV materials and improve on the performance of most silicones in harsh environments. The majority of coatings in the 2K range are hydrophobic, giving excellent protection against water immersion, salt mist and humidity, making them ideally suited for automotive electronics. 2K materials are commonly used in high performance industrial applications such as adhesives, paints and even potting materials. The systems consist of a resin portion and a crosslinker portion, that are reasonably stable when kept separate. However, once mixed in the correct ratio, an unstoppable chemical reaction begins which continues until a solid polymer is formed. By adjusting the nature of the resins and the hardeners, a wide variety of polymers can be produced from soft-rubber like materials to high-strength glass-like materials. Many of these materials are diluted with solvents, which increases the usable life of the system and enables the use of existing application methodologies. However, with the restrictions on solvent-usage, it was decided to focus on generating a solvent-free solution.

in a small, disposable static-mixer, immediately prior to application. Utilising this approach of mixing immediately prior to application, enables the use of more reactive materials, resulting in shorter cure times. The atomised spray application enables a wide range of material viscosities to be selectively applied within a normal cycle time. The use of larger pumps can enable faster cycle times, and the all metal design of the applicator provides the opportunity to heat the material to improve process consistency and enable the use of more viscous materials. This applicator technology enables all of the 2K range of materials to cure within 10 minutes at 80°C, the typical drytime and temperature for a solvent-based acrylic. Indeed, the latest addition to the 2K range cures primarily with UV radiation (conventional microwave or arc-lamp systems (UVA) or the latest LED curing technology), whilst the chemical cure ensures complete-curing within shadowed areas in just a few hours, compared with weeks or months for moisture initiated secondary cure mechanisms.

Coverage and thickness

The following cross-sections demonstrate the achievable thickness and coverage for a variety of common components. It should be clear from the following sections that the 2K materials enable a much greater thickness and perfect application coverage, to provide a higher level of protection. Performance advantages of the 2K materials can be demonstrated in three of the harshest tests employed by users today.

Thermal Shock

Powered Immersion testing in salt-water

In order to assess the ability of the coating material to withstand powered immersion in salt-water conditions, two experiments were performed. Firstly, standard IPC B-24 SIR coupons were spray-coated and cured at a variety of different thicknesses, achievable from a production process. The SIR coupons were placed in a horizontal position and powered up at 10V. Each SIR pattern was covered with 5% (w/w) saline solution, and the patterns were monitored to ensure they remained completely saturated with saline throughout the test duration. SIR measurements were recorded every minute. The experimental set-up is shown in Fig A.

Powered Condensation Testing

A populated Electrolube SIR test board was used to evaluate the NPL’s new condensation test method, prior to the launch of the current ongoing project. The boards were tested uncoated, selectively coated with a solvent-based acrylic and selectively coated with a 2K material. The board and test results for a BGA device and an SOIC are shown below. The results show that for both component types, the SIR results with the 2K coating remained 2 orders of magnitude higher and did not vary much whether the material was covered with condensed water or not. However, for the acrylic there was a fairly significant difference depending on whether the material was under condensing conditions or not. The BGA device showed evidence of dendrite formation in the uncoated evaluation.

Fig A. SIR experimental set-up The SIR measurements for the OSP coated Cu, Reflowed SAC alloy, Ultra-thin conformal coating (3 micron) and Acrylic conformal coating (50 micron) are shown below in Fig B. Whilst the acrylic material showed very low SIR values, the results were at least consistent and significantly better than the Cu-OSP value. Interestingly, the SAC alloy showed reasonable resistance to Saline, whereas the UT coating was indistinguishable from the OSP coated CU, both of which showed evidence of electrochemical corrosion.

MATERIALS

Fig B. SIR comparison of Acrylic, Solder Paste, UT and AR coatings However, when we look at the results for the 2K materials during this same test we can see that within the intended thickness range (>100 micron), there is no impact from the salt-immersion throughout the duration of the 30 hour test. At 50 micron thickness, the SIR shows some impact of the saline immersion, but the results are still 3 orders of magnitude greater than the UT or AR materials.

In the second immersion study, IPC-B52 test coupons were coated with 2K300, 2K850, UT and AR type materials by a normal application process. The coupons were cured in accordance with supplier recommendations and left or 28 days prior to commencement of the immersion test.

Conclusion

The 2K range of materials provide sharp edge coverage and protective thickness, unrivalled by other liquid applied conformal coatings. The materials have been developed specifically for thick film applications and engineered to optimise this performance advantage, whilst mitigating many of the issues associated with thick coatings, such as cracking during thermal shock testing and solder-joint lifetime degradation, especially for very sensitive devices such as BGA packages. The rigorously tested two part systems can be applied thinly (50-75μm), however, they have been designed, formulated and tested to be applied at much greater thicknesses (150300μm), to facilitate superior encapsulation of components and component leads. The materials will drop into any existing selective coating process with a simple valve modification and minimal investment. The extreme protection provided by the increased thickness and superior coverage will be valued by many Automotive and Aerospace suppliers struggling with increased demands from OEMs for improved condensation resistance and even powered up sea-water immersion conditions.

The boards were immersed in saline solution and then immediately powered at 5V. The boards were filmed during their immersion. A significant degree of bubbling and the formation of corrosion products could be seen almost immediately with both the uncoated control and the UT coating material, especially on the components. The Acrylic coated board showed almost immediate bubbling, but the formation of corrosion products took approximately 2-3 minutes. The 2K300 and 2K850 boards showed no evidence of bubble formation throughout the 30 hour duration of the immersion test.

UPDATES Infineon, Siemens Mobility New Auxiliary Converters Siemens Mobility and Infineon Technologies have collaborated to establish new auxiliary converters for various train platforms, to improve the efficiency of onboard power systems using power semiconductors based on silicon carbide (SiC). Siemens Mobility uses the new converter for various train platforms. As a result, the platforms are maintenance-friendly, reliable, economical and, above all, powerefficient. In addition to providing the AC voltage (e.g., 3 AC 400 V 50

Hz) required for the vehicle power system, auxiliary converters also deliver the required battery voltage (e.g., 110 V DC). To achieve this, they convert the DC voltage provided at the converter input. They ensure that train passengers can charge laptops and smartphones; the air conditioning and ventilation systems are running, and the onboard restaurant can offer hot and cold drinks and food. Without them, connectivity, information or entertainment services on trains would not be available. As part of the system, SiC reduces the overall costs in the on-board electrical system and the energy consumption of the auxiliary converter. It also enables more compact and lighter converter designs, along with a modular and service-friendly design to ensure lower maintenance costs.
