EMC Technologies has commissioned a new semi-anechoic chamber (SAC) in Sydney at its Seven Hills laboratories. The SAC is NATAaccredited as an alternative (indoor) Open Area Test Site (iOATS) and is suitable for the testing of most products requiring EMC compliance for radiated emissions up to 40 GHz including most CISPR standards, MIL-STD461/2, DO160F and regulatory requirements such as C-tick/ RCM, FCC, IC, CE and VCCI. The chamber was designed and installed to be the largest such chamber in Sydney. EUT size), a bore-site antenna mast and a 3 and 10 m of usable space. These important features allow convenient indoor testing of large items for both Class A and B limits (for most standards) without the inherent problems associated with travelling and testing at open area sites. Testing at 10 m is carried out at the Colo OATS or at EMC’s Melbourne 10 m iOATS if outdoors testing is not suitable. The iOATS is compliant with: CISPR 16-1-4 for a 2 x 2 x 2 m test volume (quiet zone) to 18 GHz; FCC, IC, VCCI, CISPR 11, 12, 13, 15, 22 (Class B), 24, 25 and 32; immunity standards IEC/EN 61000-4-3, ISO 11451-2, ETSI/EN wireless standards and many others.

Mobile devices, including smartphones and tablets, have become a disruptive technology that is shaking up the norms of system architecture. Traditional methods of introducing power and managing I/O are undergoing changes that are having major implications for traditional connectors. Read on to find out how.

onnectors of all types have been an integral element in the packaging scheme of electronic products for many years. Internal wire-to-wire, wire-to-PCB and PCB-to-PCB connectors allow designers to economically partition a system into manufacturable modules, which offer ease of repair as well as scalability. External connectors are used to introduce power and provide input/output signalling to the outside world. Huge advances in semiconductor integration have enabled electronic equipment that is infinitely more powerful, even while shrinking from refrigerator-sized profiles to handheld portable devices. Products that required a daughtercard loaded with discrete devices can now be built around a single chip. The internal interconnections between board, power supply and display on many consumer products are often replaced by PCB traces on a single board, or a flex circuit. Port density has become a major issue. We have watched as venerable I/O interfaces, such as the RS232 and Centronics connectors, were replaced by Firewire and USB connectors. These connectors not only offered increased port density, but also provided dramatically higher data transfer rates in a user-friendly profile. As devices become smaller, the space available for interconnection is reduced, which has spawned even smaller interfaces, including mini and micro versions of USB, as well as mini versions of DisplayPort and HDMI.Â The new Thunderbolt interface from Intel does double duty in supporting both DisplayPort and PCIe technology. Products that in the past sported a collection of different video, audio, power, headphone, daughtercard, memory, processor and peripheral connectors have been replaced by a few flex circuit connectors inside, and one or two micro USB external interfaces.

The consumer world is quickly moving away from the desktop and even the laptop computer towards mobile devices. A recent report indicated that personal computer sales plunged 14% in the first three months of 2013, nearly double the anticipated drop, while tablets and smartphones grew at double-digit rates. Along with increased computing capability, silicon chips have been trained to consume dramatically less power. Not only does this facilitate tighter system packaging, but it also enables devices to cut their power cord tether and operate for hours using lightweight rechargeable batteries. Short-range wireless communication is a perfect complement to these mobile devices and consumers are quickly adopting this technology. For example, the USB connector has served as the standard PC printer interface, but the majority of printers now feature a wireless link that eliminates a copper cable entirely. Wireless charging pads using inductive coupling are becoming more common, again eliminating the power connector. Several concepts for wireless charging of vehicles have been proposed. A wireless charger built into the floor of a garage could safely recharge the batteries of an EV car while it is parked, with no intervention by the driver. The ultimate solution would be to eliminate all external connectors, but thatâ&#x20AC;&#x2122;s heresy among connector manufacturers and not very likely in the foreseeable future. Profiles would be unconstrained by a connector, and sealing the device against moisture and dust becomes easier. Reliability would be increased without the potential for failure that comes with an abused connector. Consumers would appreciate the reduced clutter and improved user experience. We may never get there, but wireless technology continues to whittle away at many standard I/O interfaces. There is certainly no lack of short-range wireless technologies waiting to take the

CONNECTORS BUILDING WIRELESS CONNECTIVITY INTO A DEVICE IS BECOMING EASIER AS COMPLETE TRANSMITTER AND RECEIVER MODULES ARE ENTERING THE MARKET, FREEING UP PRODUCT DESIGNERS TO FOCUS ON THEIR PRODUCT DEVELOPMENT. SYSTEMS ON A CHIP (SOC) WITH INTEGRATED WIRELESS CONNECTIVITY ARE SHOWING THE GREATEST GROWTH. THE RFDURINO, FOR EXAMPLE, IS A FINGER-SIZED MICROCOMPUTER WITH INTEGRATED BLUETOOTH COMMUNICATION CAPABILITY.

place of copper interfaces. Our homes are festooned with multiple remote controls that utilise infrared beams to control a host of consumer audio and video equipment. Additional wireless standards have been cropping up like spring weeds. Among the contenders: • ANT+: proprietary wireless sensor networks. • Cellular: Now being adapted for machineto-machine applications. • IEEE 802.15.4: Peer-to-peer links in industrial sensor networks. • ISA 100A: Designed for applications in industrial process control. • Wi-Fi, IEEE 802.11: Enables smartphones, laptops, tablets and video equipment to communicate with a local router. • ZigBee: Often used in home automation networks. • Bluetooth: One of the most widely adopted technologies, used in everything from automotive entertainment to headphones. Worldwide shipments of integrated circuits that feature integrated Bluetooth are forecast to rise to 3.1 billion units by 2017, a 91% increase over 2011 shipments. Each of these technologies has established special interest groups that facilitate and promote the growth of their chosen protocol. Building wireless connectivity into a device is becoming easier as complete transmitter and receiver modules are entering the market, freeing up product designers to focus on their product development. Systems on a chip (SOC) with integrated wireless connectivity are showing the greatest growth. The RFdurino, for example, is a finger-sized microcomputer with integrated Bluetooth communication capability. The growth of wireless connectivity is likely to continue at even faster rates as it becomes easier to integrate this technology into new products. Microchip recently unveiled a major expansion of its embedded wireless modules that support Bluetooth, Wi-Fi and ZigBee. These drop-in assemblies consume very little power and quickly enable short-range or internet access. Some of these device suppliers offer a progression of capabilities to provide a footprint-compatible migration path to greater functionality. The advent of cloud computing reduces

the need for computational horsepower in the mobile device with access to applications available as needed and almost unlimited storage in the cloud. This reduces the need for large internal storage capacity. We may be returning to the era of dumb terminals. Emerging wireless technologies, such as millimetre waves, continue to be introduced as demand for bandwidth-intensive applications increases. Innovative devices that operate in the 30 to 300 GHz frequency spectrum are used to provide a wireless short-range link among multiple devices, including set-top boxes, HDTVs, DVD players, game boxes, HD projectors and laptop computers. Industrial automation and control is another area where wireless communication among sensors can reduce the copper infrastructure in process control applications. Banner Engineering recently introduced a completely self-contained wireless photoelectric sensor that features an integrated battery and radio. These sensors eliminate the need for an external power source as well as I/O signal cabling. Systems can be quickly reconfigured without costly wiring changes. Near-field communications (NFC) is another area currently under intense investigation. These RF links differ from others in their ability to exchange relatively small packets of information in a burst mode over very short distances, typically less than 10 cm. A series of standards that define NFC communication in smartphones and similar devices are based on RFID (radiofrequency identification) technology. Devices must only be in close proximity or touch in order to automatically establish a contactless transac-

tion. During initiation of a link, an RF field is generated that can power a passive receiver, such as tags, key fobs or credit cards, which do not require a battery. Peer-to-peer communication between two NFC-enabled devices is also part of the specification. The initial target applications that were focused on mobile payment also envisioned smart car keys, security access cards and ID cards. A single NFC card was forecast to replace the wallet and could be used in all e-commerce exchanges. The NFC-enabled credit card has experienced less than universal approval in the United States, as hackers demonstrated the ease by which these cards could be read by simple scanners. Other applications related to social networking and ticketing installed on smartphones have been more successful. Friends need only tap their phones together to share photos, videos and contacts. We are starting to see a form of wireless connectivity being explored. TE Connectivity recently announced the ARISO contactless technology platform, which utilises its expertise in magnetics, RF transmission and antennas to create an inductively coupled near-field interconnect. Data signals and power can be transmitted across a gap of a few millimetres between the ‘mating’ connector faces. Initial applications are seen where voltage isolation, mechanical rotation or explosive environments make conventional connectors impractical. There is little doubt that consumers want mobile access to the full array of communication, entertainment and information that has traditionally been tied to a wire. Mobile devices have shrunk in size and weight, leaving little room for traditional external I/O connectors. Wireless technology addresses that demand. On one hand, the evolution to wireless connectivity will result in reduced volumes of what have become low-margin commodity connectors. On the other hand, the infrastructure consisting of thousands of cellular access points and supporting high-speed networks will require continuous upgrades in order to support increasing demand for bandwidth. We are now only on the leading edge of what will become the ‘Internet of Things’, which includes machine-to-machine communications. The connectors typically used in this equipment provide high signal density, operate at multigigabit data rates and are designed for much higher levels of reliability. It is unclear exactly how long it will take for these trends to play out, but for sure times are changing Robin Pearce, Bishop & Associates rpearce@bishopinc.com

membranes and overlays, motors and drives, PCB design and fabrication, power converters, batteries and supplies, prototyping verification equipment and software, rework tools, microwave RF and wireless solutions, service and maintenance equipment, semiconductor and microchip technology, soldering supplies, solar supplies, switches, test equipment, touch screens and controls, wire and harness. The Surface Mount and Circuit Board Association (SMCBA) Electronics Design & Manufacture Conference 2013 is being held in conjunction with the exhibition. The two-day CAD library management for electronics design workshop will present a practical guide to the many issues facing a design team in establishing and maintaining an effective library structure that is expandable and flexible, yet ensures a discipline of process for establishing procedures, standards and methods of working that are accepted and adopted by all concerned for achieving consistent and reliable results. Electronic design starts with CAD libraries, and if part numbers, footprints, symbols and models are not correct then project failure will occur. This will lead to delays and extra expense for redesigns. Tom Hausherr from PCB Libraries will deliver this workshop. Martin O’Hara, EMC expert and author of EMC at Component and PCB Level will present his renowned workshop ‘Circuit Board & Layout Issues for EMC Compliance’. Martin will provide essential background knowledge and best design practices for improving the EMC performance of any circuit design. Dave Hillman from Rockwell Collins returns to address the many issues faced and to be considered in the manufacture of electronic products.

AUTOMATED OPTICAL INSPECTION SYSTEMS Sherlock-300 series automated optical inspection (AOI) systems provide good defect coverage, average cycle times of 10 s/board (including transport), low false call and false accept rates (FCR and FAR) for a wide range of production environments. All three models - benchtop, inline and batch - feature as standard fast multitouch touch-screen control. The system is capable of detecting: majority of all solder joint defects; component defects and issues; shifting; tombstones; reverse polarity; damaged parts; bent IC leads; pin presence (THT); bent pins (THT); reverse polarity. All programming and operation is done through the intuitive touch-screen interface. Automatic pick and place and CAD data conversion and a predefined, customisable parts library not only speed up programming but also eliminate the need for skilled AOI personnel. The Sherlock 300 library contains comprehensive inspection data for each part, including image processing settings, lighting conditions, areas to be checked, and more. Custom parts can be quickly created from any predefined part. Sherlock-300F uses a high-resolution, 2.2 MP CMOS camera, a large-aperture telecentric lens and two lighting systems to achieve fast, accurate inspection of both solder quality and components at a scanning rate of 50 cm 2/s. The RGB LED lighting system inspects solder fillets for volume and shape. The three-tier white lighting system inspects component placement and positioning, with reflection and shadow controls to ensure low false calls and low false accepts. The standard lens inspects parts down to 0201, or the Sherlock-300F can be fitted with a high-magnification lens to inspect parts down to 01005. During inspection, the camera moves, rather than the PCB. This ensures the clearest possible images and fastest inspection speeds. The camera motion system is X-Y bi-axial belt-driven with 50 µm positional accuracy. The board transport system automatically adjusts to the size set in the program. Sherlock-300F comes standard with a pneumatic PCB stopper and vacuum clamp. It can optionally be purchased with a motor to eliminate the need for a compressed air source.

FASTEST COMPUTER

NEW SUPERCOMPUTER HAS THE POWER OF 56,000 COMPUTERS

Australia’s most powerful computer Raijin, named after the Japanese god of thunder, lightning and storms, can perform the same number of calculations in one hour that would take seven billion people armed with calculators 20 years. The computer was officially launched at the opening of the National Computational Infrastructure (NCI) high-performance computing centre at The Australian National University (ANU).

ith peak performance speeds of 1.2 petaflops 1,200,000,000,000,000 floating point operations per second - the new computer has the power of 56,000 computers working in parallel, and the disk storage equivalent of 20,000 computers but working much faster. It can perform the same number of calculations in one hour that every one of the 7 billion humans on Earth, armed with calculators, could perform in 20 years - or 170,000 calculations per second, per person on Earth. The Fujitsu Primergy, Raijin, will to enable researchers to process vast volumes of data that would otherwise take years to complete and simply not be possible using desktop computers. It will be available to users in a phased approach starting early next week. “Advanced computational methods form an increasingly essential component of high-impact research, in many cases underpinning discoveries that cannot be achieved by other means, as well as underpinning the platform with which to sustain innovation at an

internationally competitive level,” said Professor Lindsay Botten, Director of the NCI. Raijin is a high-performance cluster with 57,472 cores (Intel Xeon Sandy Bridge 2.6 GHz), Mellanox FDR interconnect, 160 TB of main memory and 10 PB of useable fast filesystem, running the OneSIS cluster manager and the PBS Pro workflow manager. The computer’s speed enables researchers to run complex models. They might, for example, seek to understand the forces that bind the building blocks of our universe, to ‘supercharge’ the photosynthesis of virtual crops or to understand the dynamics of the world’s oceans and their impact on the climate. The operation of the NCI is sustained through co-investment by a number of partner organisations including ANU, CSIRO, the Bureau of Meteorology, Geoscience Australia and other research-intensive universities supported by the Australian Research Council, the total of which amounts to a further $50 million over four years.

BMW i3 and power electronics

f desired, the BMW i3 is also available with a range extender, which maintains the charge of the lithium-ion battery at a constant level en route, as soon as it falls below a specified value. This is performed by a two-cylinder gasoline engine with 34 hp (25 kW), mounted adjacent to the electric motor above the rear axle. The range extender increases

the car’s maximum range in day-to-day driving to around 300 kilometres. With a curb weight of 1195 kg, the BMW i3 is said to be lighter than most vehicles in the compact segment, yet offers significantly more space for up to four occupants. Below are some key features. Electric motor The electric motor of the BMW i3 was designed for use in city traffic and provides 125 kW/170 hp with a torque of 250 Nm. The full torque, which is typical for electric motors, is immediately available from a standstill and does not need to be built up first via the engine speed, as is the case with combustion engines. The BMW i3 accelerates from 0 to 60 km/h in under 4 seconds and to 100 km/h in only 7.2 seconds (7.9 seconds in the version with range extender).

Lithium-ion high-voltage battery The energy supply for the drive, as well as all other vehicle functions, is provided by a specially developed lithium-ion high-voltage battery, which sets new standards in terms of energy efficiency. The intelligent heating/cooling system of the high-voltage battery ensures that energy performance (and thus the vehicle’s range) is less affected by temperature fluctuations than it normally is with batteries of this type. This makes a significant contribution to both the performance and service life of the cells. An eight-year warranty or 100,000 miles is given for the high-voltage battery (for 70% of the charging capacity). Via the supplied charging cable, the battery is already charged for 80% capacity in 6-8 hours (based on 16 A current). The charging duration can be reduced by approximately 30% with the optionally available Wallbox Pure. Intelligent energy management To allow for an optimal range in every driving situation, during the development of the BMW i3 particular emphasis was placed on low energy consumption of the electrical components. For example, the interior heating system is said to save up to 30% of electricity compared to a conventional electric-heating system. Energy-saving LEDs are used for the interior lighting and are also available as an option for the exterior lighting. In addition, the E-drive offers the possibility of braking via the accelerator pedal. If the driver takes his foot off the accelerator pedal, the electric motor assumes the function of a generator and feeds the energy gained from the motion of the wheels back into the highvoltage battery. This so-called energy recuperation generates a braking torque which leads to an effective deceleration of the vehicle and pays off in terms of energy savings for especially foresighted driving styles. Charging the BMW i3 The BMW i3 can not only be charged at home using the wallbox or the charging cable, it can also be charged on the go from a continuously increasing number of official charging stations. The BMW i3 finds these easily via innovative BMW ConnectedDrive Services such as, for example, the fully networked BMW i Navigation with display of the dynamic range and charging stations. BMW Group

PASSIVE JUNCTION BOX

The Truevolt series digital multimeters help engineers see their measurement data in new ways, get actionable information faster, and document their results more easily. Exclusive Truevolt technology reduces extraneous factors such as noise, injected current and input bias current for increased measurement confidence. The Agilent 34461A DMM is a direct replacement for the industry-standard Agilent 34401A DMM, and was designed to make migration easy for current users of the 34401A. These multimeters offer engineers a basic entry point to the 6½ digit class of DMMs.

Turck’s 6-port M12 passive junction box is designed to easily integrate multiple devices into a single unit. It allows simple installation in diverse factory automation applications, ranging from packaging and automotive to material handling and mobile equipment. With one or two discrete signals per port, the 6-port junction box is capable of providing up to 12 discrete signals - providing connectivity for multiple devices. The junction box consolidates several discrete devices in an area to one device, which is then connected to a controller via a single cable. This eliminates each device requiring an individual cable, delivering a more cost-effective, streamlined connectivity solution. The 6-port model provides 2 A of current per signal and up to 9 A total current per junction box. For durable performance, the M12 passive junction box features IP67-rated ingress protection and operates in temperatures ranging from -40 to +85°C.

Opera-3D finite element software for electromagnetic design with a solver that can be used to analyse natural vibration modes. Electrical machine developers can employ the tool to investigate and minimise forces that might cause oscillations close to the natural frequencies of the equipment and thereby avoid excessive vibration or collisions between rotating and stationary parts. By capturing such mechanical vibration in conjunction with electromagnetic modelling, and thermal performance if required, the integrated 3D tool suite can greatly reduce the complexity and timescales of design projects. One of the key benefits of this capability is a further reduction in the need to create physical prototypes to explore the behaviour of a proposed design concept. With the greater understanding of new designs that more thorough simulation brings, it can be possible to reduce the real-world prototyping phase to a few iterations. This can take months out of design cycles - along with the associated high costs. The latest version of the software extends the fundamental performance advantage of Opera for many common design engineering applications. The modal solver - STRESS/EV - finds a user-specified number of eigenvalues within a specified frequency range and calculates the eigenvectors of each mode. It works in conjunction with the static stress analysis capability of Opera that calculates the deformation, stresses and strains of a body which is subject to external and internal forces. The forces calculated from electromagnetic fields can be used as input to the stress analysis.

CLEANING

IN ELECTRONICS MANUFACTURING Doris Schulz, parts2clean

Increasing demand for reliability, continuing miniaturisation and the growing number of faults in electronic components manufactured in no-clean processes have put the focus back on cleaning in electronics manufacturing. This article looks at different solutions that help ensure optimal cleaning of components.

he development of no-clean fluxes and soldering pastes had turned the attention away from the need to clean components in electronics manufacturing. For many components that are only used in non-critical atmospheric environments, this mostly poses no problem. However, where they are used in adverse environments (such as humid or fluctuating temperatures), the protective layer applied in the no-clean process can be gradually eroded, releasing ionising substances that promote electromigration and dendritic growth. This occurs chiefly in narrow spaces beneath components and between their connections or other contact surfaces.

Surface cleanliness Protective coatings (conformal coatings), progressive miniaturisation, wire bonding and the increased use of high-voltage components all call for a high level of surface cleanliness. A further aspect is the use of lead-free solders, containing a higher proportion of fluxes and more aggressive activators that can cause problems. Cleaning of electronic components also involves removing potentially hazardous impurities such as fluxes, residues of soldering agents and adhesives, and such contaminants as dust and residue from previous manufacturing stages.

26 SEPTEMBER/OCTOBER 2013

Choosing the right cleansing agent A key factor in achieving economy and efficiency in the cleaning process is the selection of a suitable cleansing agent. Selection criteria include the nature and quantity of the impurities to be removed, and the subject material. Cleaning agents currently used in electronics manufacturing include solvents, water-based media containing alkaline surfactants and water-based, tenside-free cleaning agents. The electronics industry mainly uses solvents containing nonhalogenated hydrocarbons, modified alcohols or hydrofluorethers (HFEs). HFEs were developed as an alternative to the previously preferred chlorofluorocarbons (CFCs), after CFC manufacturing was stopped about 20 years ago due to its high potential for breaking down the ozone layer. Non-inflammable HFEs have similar properties to CFCs, but pose no danger to ozone, do not persist in the atmosphere and have low greenhouse potential. At the same time, they offer physical properties that are in demand for cleaning of electronics, such as relatively high density, low viscosity and low surface tension. These solvents are used in mono-solvent, cosolvent and bi-solvent systems. A mono-solvent system uses a pure HFE or an azeotrope - a mixture of two or more components that vaporises without chang-

soundwaves in the fluid bath. In general, the lower the electrical signal frequency, the greater the energy released by the soundwaves. There are multifrequency systems that permit acoustic irradiation of the goods to be cleaned at different frequencies; the optimum combination of cleansing agent and ultrasound frequency can be determined from cleaning tests, carried out by the suppliers of the equipment or the cleaning agent. In selecting the type of cleaning equipment to use, key questions are: What throughput must be handled? What space is available in which to set up the equipment? How can the cleaning process be integrated into the manufacturing chain?

Dry alternatives with carbon dioxide

ing its chemical composition. It is used to remove slight impurities such as light oils, halogen compounds, residue of easy-clean solvent, particles and dust. The co-solvent system consists of an HFE combined with a low-volatility organic solvent as solubility promoter. The solubility promoter removes impurities from the surface of the work piece, and the HFE rinses away the solvent and the impurities from the components. Cleaning by co-solvent procedure is extremely versatile and also gives good results with the most stubborn impurities such as heavy oils, grease, waxes, NC-flux residues, adhesives and hot-melt glues. Choice of a low-volatility organic solvent allows material compatibility to be tested. Co-solvent and bi-solvent systems differ mainly in that, for the co-solvent system, the solvent and the rinsing agent are mixed together, while in the bi-solvent process they are kept separate.

Optimising a process by adapting the plant technology To ensure efficient and reproducible cleaning, it is essential to match the cleaning agent to the plant technology. That is why so many different cleaning systems, such as dipping plants with ultrasound or pressure-flooding and spray-cleaning plants, are available. Solvents are used today in totally enclosed cleaning units. Ultrasound cleaning with solvents or water-based media offers a wide range of applications in electronics manufacturing. Another factor that influences the cleaning action, in addition to the cleansing agent, is the frequency of the electrical signals from the ultrasound generator, which converts the oscillating system to

WWW.ELECTRONICSONLINE.NET.AU

Cleaning with compressed carbon dioxide provides an extension to the wet-chemical process. The term “compressed carbon dioxide” indicates CO2 that has been converted to liquid form (that is, into its supercritical phase) under pressure. In this form, it possesses excellent properties as a solvent upon a range of nonpolar impurities such as grease and oils. Supercritical CO2 has low viscosity and low interfacial tension, resulting in improved ability to penetrate crevices. This enables cleaning of components with highly complex geometries such as tiny drilled holes and the narrowest of cracks. In electronics manufacturing, this technology offers the ability to clean such items as complete PCBs and assemblies, removing flux residues and cleaning away oils and grease from metallic components such as contacts. It meets the requirement for an environmentally friendly, dry and residue-free procedure. Liquid carbon dioxide is also used as the medium in CO2 snowjet cleaning - in this case, in the form of minute snow crystals. With its combination of chemical, thermal and mechanical properties, the non-poisonous and non-inflammable CO2 snow removes surface films and particulate contamination leaving no residue, and can also be used selectively on functional areas such as contact points. Since the cleaning is itself a dry process, there is no need for an energy-intensive subsequent drying procedure. The procedure is employed in the most diverse of applications in electronics manufacturing, such as in preparation for bonding processes, equipping PCBs and foil-PCBs, and in the manufacture of metal-insulator semiconductors (MISs), to allow custom-tailored and reliable manual or fully automated cleaning.

The 4th state of matter Plasma, a gaseous mixture of atoms, molecules, ions and free electrons, allows efficient surface treatment of electronic parts and components of different materials, simultaneously cleaning away organic impurities such as oils and grease and activating the surface. This double function is based on a physical and chemical reaction during the procedure. Depending on the application in question, low-pressure plasmas or inline-capable atmospheric pressure plasmas can be used. With low-pressure plasmas, both oxidising and reducing processes can be carried out. An oxidising plasma can clean away organic contaminants such as grease, oil and adhesive residue prior to soldering or bonding. A reducing plasma process can be used, for example, to improve bonded connections by reduction of electroplated metallic layers. Surface cleaning and activation by atmospheric pressure plasmas is used in the electronics industry in such tasks as pre-printing, bonding or casting of electronics boards and semiconductors, manufacture of optoelectronic components and prior to wire-bonding. parts2clean www.parts2clean.de

SHORTcircuits A BATTERY MADE OUT OF WOOD? A sliver of wood coated with tin could make a tiny, long-lasting, efficient and environmentally friendly battery, according to researchers at The University of Maryland. But don’t try it at home yet - the components in the battery tested by The University of Maryland scientists are a thousand times thinner than a piece of paper. Using sodium instead of lithium, as many rechargeable batteries do, makes the battery environmentally benign. As sodium doesn’t store energy as efficiently as lithium, it is not suitable for use in mobile phones but it could be used to store huge amounts of energy at once, such as solar energy at a power plant. Existing batteries are often created on stiff bases, which are too brittle to withstand the swelling and shrinking that happens as electrons are stored in and used up from the battery. Liangbing Hu, Teng Li and their team found that wood fibres are supple enough to let their sodium-ion battery last more than 400 charging cycles, which puts it among the longest lasting nanobatteries. “The inspiration behind the idea comes from the trees,” said Hu, Assistant Professor, Department of Materials Science and Engineering, The University of Maryland. “Wood fibres that make up a tree once held mineral-rich water, and so are ideal for storing liquid electrolytes, making them not only the base but an active part of the battery.” Lead author Hongli Zhu and other team members noticed that after charging and discharging the battery hundreds of times, the wood ended up wrinkled but intact. Computer models showed that that the wrinkles effectively relax the stress © stock.xchng/profile/ThreeOak in the battery during charging and recharging, so that the battery can survive many cycles. “Pushing sodium ions through tin anodes often weaken the tin’s connection to its base material,” said Li, Associate Professor of mechanical engineering. “But the wood fibres are soft enough to serve as a mechanical buffer, and thus can accommodate tin’s changes. This is the key to our long-lasting sodium-ion batteries.” The team’s research was supported by The University of Maryland and the US National Science Foundation. The full paper is available here.

Motion sensing is fast becoming a ‘must-have’ function in consumer electronics today. Gyro sensors, also known as gyroscopes, are the motion-sensing devices that enable such functionality by sensing changes in angular velocity. In addition to their use in consumer electronics, gyro sensors can be integrated with portable medical devices and sports equipment, allowing patients to be monitored remotely by medical staff and athletes’ motion to be tracked for training purposes. The A*STAR Institute of Microelectronics and Japan’s Shikino High-Tech Co have signed a research agreement to pioneer an energy-efficient, high-performance application-specific integrated circuit intellectual property (ASIC IP) block for a gyro sensor to be installed in commercial handheld devices. Yuaki Osada, president of Shikino High-Tech, believes that the IME is an excellent choice of collaborative partner for the project due to the institute’s proven and outstanding capabilities, particularly in the area of analog technology development. “It is a valuable opportunity for Shikino High-Tech to work with the IME in this advanced technology project,” says Osada. Dim-Lee Kwong, executive director of the IME, is enthusiastic about the venture with Shikino High-Tech. Noting the IME’s extensive research experience with Japanese companies, he is confident that the partnership will benefit both Shikino High-Tech and A*STAR. “This new collaboration will no doubt provide a strategic platform for the IME’s researchers to leverage existing capabilities in the development of innovative gyro sensor technologies.”

FUNDING BOOST FOR HEARING RESEARCH The HEARing Cooperative Research Centre (CRC) has received confirmation that it has been awarded $662,115 by the NSW Government Medical Devices Fund (MDF) to develop a device that monitors brainwaves to determine how well people can hear. Known as the automatic Cortical Audiometer, the device will be developed by the HEARing CRC and its Core Member, the NSW-based National Acoustic Laboratories (NAL), to improve the accuracy, efficiency and reliability of hearing tests. Adj Prof Harvey Dillon, NAL Research Director, said: “Traditionally hearing tests require verbal or behavioural responses from the patient - which is often a challenge when the patient is a baby, infant or young child with multiple disabilities, or is unwell in more advanced age, in particular those suffering from a stroke or dementia. “The new tool will use electrical responses from the brain, called auditory-evoked responses, to automatically assess hearing capabilities and to produce an individualised audiogram. That’s a graphical measure of the patient’s hearing status. This process is simple, painless and bypasses the need for traditional patient responses.” Adj Prof Dillon explained: “All that is needed is that the patient be awake and reasonably quiet. As the responses come from the brain’s auditory cortex, it measures the response of the complete hearing mechanism, allowing it to be used with all types of hearing loss.” He continued: “Making the testing procedure and subsequent data analysis automatic opens up new opportunities for the test to be performed by non-specialist clinicians or even health technicians. Furthermore, the test will save valuable time during a consultation, allowing the clinician to spend more time discussing follow-up and treatment options with the patient and carers.” The Cortical Audiometer will run on the award-winning HEARLab platform, a diagnostic and rehabilitation device previously developed by the HEARing CRC and NAL. The HEARLab concept was licensed and made available internationally through FRYE Electronics in 2011, with ongoing software development by the original team at the HEARing CRC and NAL. © stock.xchng/profile/KillR-B

MOUSER ELECTRONICS FOCUSES ON MEDICAL IMAGING

WWW.ELECTRONICSONLINE.NET.AU

Mouser Electronics has released an enhanced version of its medical applications site. New features focus on medical imaging solutions including MRI, portable ultrasound and digital X-ray, helping engineers to solve a unique set of design challenges. MRI requires high-speed data and image processing to create soft tissue images, making high-performing processors requisite components. Noise can compete and corrupt the MRI signal, so essential precision components must be ultralow-noise devices that are temperature stable. Portable ultrasound technology demands that engineers maintain precise image quality while addressing the portability issues such as size and power efficiency for extended battery life. The main challenge with designing for digital X-ray is decreasing the noise from the system’s electronics. All parts have to be ultralow noise or adequately filtered. Image contrast and temperature stability are other important challenges. With the medical applications site expansion, engineers are supplied with resources and application notes to educate designers on the newest technology and product solutions to face the design challenges of medical imaging. Application spotlights incorporate interactive block diagrams for easy navigation to a broad selection of products, organised by product category. Featured products include Stratix III, Altera’s high-performance FPGA for data-centric applications; TI AFE5808A, an integrated Texas Instruments Analog Front End (AFE) specifically designed for portable ultrasound systems; and a new high-speed/lownoise rail-to-rail output amplifier from Analog Devices.

The series supports a wide range of demanding signal generation requirements in defence electronics, highspeed serial, optical networking and advanced research applications. The generators give design engineers and researchers the ability to create, generate or replicate ideal, distorted or ‘real-life’ signals, an essential step in the design and measurement process. The AWG70000 offers bandwidth on demand by generating wide bandwidth signals at baseband, IF and RF frequencies up to 20 GHz, with greater than -80 dBc dynamic range. With up to 16 GSa of waveform memory, it can generate unique signals that are long enough to simulate real-world environments. Researchers developing new and faster optical technologies can use the sample rate and high vertical resolution of the generator to very high bandwidth signals with good spectral purity. Multiple units can be synchronised together to provide a complete IQ signal generation at these high bandwidths. The generator also offers a two-box solution for HDMI 2.0, supporting four lanes at 6 Gbps per lane. The signal performance of the generator matches or is said to be better than current solutions with an SFDR spec that is up to -80 dBc.

BORON NITRIDE NANOTUBES

TRANSISTORS FROM NANOSCALE INSULATORS It is now possible - even routine - to place millions of transistors on a single silicon chip. But transistors based on semiconductors can only get so small.

t the rate the current technology is progressing, in 10 or 20 years, transistors won’t be able to get any smaller, said physicist Yoke Khin Yap of Michigan Technological University. “Also, semiconductors have another disadvantage: they waste a lot of energy in the form of heat.” Scientists have experimented with different materials and designs for transistors to address these issues, always using semiconductors like silicon. Back in 2007, Yap wanted to try something different that might open the door to a new age of electronics. “The idea was to make a transistor using a nanoscale insulator with nanoscale metals on top,” he said. “In principle, you could get a piece of plastic and spread a handful of metal powders on top to make the devices, if you do it right. But we were trying to create it in nanoscale, so we chose a nanoscale insulator, boron nitride nanotubes, or BNNTs, for the substrate.” Yap’s team had figured out how to make virtual carpets of BNNTs, which happen to be insulators and thus highly resistant to electrical charge. Using lasers, the team then placed quantum dots (QDs) of gold as small as three nanometres across on the tops of the BNNTs, forming QDs-BNNTs. BNNTs are the perfect substrates for these quantum dots due to their small, controllable and uniform diameters, as well as their insulating nature. BNNTs confine the size of the dots that can be deposited. In collaboration with scientists at Oak Ridge National Laboratory (ORNL), they fired up electrodes on both ends of the QDs-BNNTs at room temperature, and something interesting happened. Electrons jumped very precisely from gold dot to gold dot, a phenomenon known as quantum tunnelling. “The electrons hopped between the gold stepping stones. The stones are so small, you can only get one electron on the stone at a time. Every electron is passing the same way, so the device is always stable.”

WWW.ELECTRONICSONLINE.NET.AU

Yap’s team had made a transistor without a semiconductor. When sufficient voltage was applied, it switched to a conducting state. When the voltage was low or turned off, it reverted to its natural state as an insulator. Furthermore, there was no ‘leakage’: no electrons from the gold dots escaped into the insulating BNNTs, thus keeping the tunnelling channel cool. In contrast, silicon is subject to leakage, which wastes energy in electronic devices and generates a lot of heat. Other people have made transistors that exploit quantum tunnelling, says Michigan Tech physicist John Jaszczak, who has developed the theoretical framework for Yap’s experimental research. However, those tunnelling devices only operate at liquid-helium temperatures. The secret to Yap’s gold-and-nanotube device is its submicroscopic size: one micron long and about 20 nanometres wide. “The gold islands have to be on the order of nanometres across to control the electrons at room temperature,” Jaszczak said. “If they are too big, too many electrons can flow.” In this case, smaller is truly better: “Working with nanotubes and quantum dots gets you to the scale you want for electronic devices.” “Theoretically, these tunnelling channels can be miniaturised into virtually zero dimension when the distance between electrodes is reduced to a small fraction of a micron,” said Yap. Yap has filed for a full international patent on the technology. Their work is described in the article ‘Room Temperature Tunneling Behavior of Boron Nitride Nanotubes Functionalized with Gold Quantum Dots’, published online in Advanced Materials. In addition to Yap and Jaszczak, co-authors include research scientist Dongyan Zhang, postdoctoral researchers Chee Huei Lee and Jiesheng Wang, and graduate students Madhusudan A Savaikar, Boyi Hao and Douglas Banyai of Michigan Tech; Shengyong Qin, Kendal W Clark and An-Ping Li of the Center for Nanophase Materials Sciences at ORNL; and Juan-Carlos Idrobo of the Materials Science and Technology Division of ORNL.

STAND A7 PORTABLE APPLIANCE TESTER The Seaward PAC3760 Plus II portable appliance and RCD tester is based on the PAC3760 series of portable appliance testers. The Plus II version builds on the range’s features to now include an in-built isolation transformer. This feature not only eliminates the need to purchase a separate isolation transformer when testing portable RCDs, but also reduces equipment weight as the isolation transformer typically weighs several kilograms. The tester conducts earth bond, insulation and polarity tests, as well as leakage current tests for Class I and Class II appliances and leads, and carries out trip time tests of 10 and 30 mA portable RCDs. When used in conjunction with the optional PAC-TPL 3 phase adaptor, the Plus II can also carry out 3 phase leakage testing of 10, 16, 20 and 32 A three-phase appliances. The Plus II operates under mains or battery power, providing users with maximum flexibility. The unit is designed with 6-button operation: Class I, Class II, Leakage, 10 mA RCD, 30 mA RCD and three-phase test buttons. Results are displayed as a pass or fail as well as actual readings. Once the user selects the required test, the tester conducts an automatic sequence of tests, eliminating the need for complicated on-screen menus. Other features include automatic sensing of IEC or extension leads, which adds a polarity test to the sequence and automatic detection of whether the appliance is switched ‘On’. The tester’s in-built isolation transformer and ability to operate under both battery and mains power make it suitable for manual testing and tagging applications requiring compliance with AS/NZS3760.

REVOLUTIONISING ELECTRONICS THROUGH GRAPHENE Mike Smyth, specialist technical writer

Graphene has the potential to change the world of electronics in much the same way that transistors and integrated circuits did last century. But use of this wonder material is still very much in the development stage in many laboratories and research centres around the world and, while promises are high, the widespread practical use of graphene is proving elusive.

t the pinnacle of research is the British $92m institute now being built at Manchester University, the home of graphene discovery. All eyes are now on the completion of this facility in 2014 to speed up the practical use of this substance that has taken the electronics industry by storm. Australia, too, is contributing to the knowledge bank of graphene. Scientists at the CSIRO and the Royal Melbourne Institute of Technology have already worked out a way to make high-speed electronics possible. This fits in well with other researchers around the world who are working on a variety of projects, all designed to bring graphene to commercial adoption as soon as possible. Some of their efforts include a graphene-based, highly conductive ink that is tolerant to bending, which has been developed at Northwestern University, a private research facility in the US. Patterns have been printed that could be used for highly detailed conductive electrodes. Although this is a promising use of the material, it is not without its challenges. The difficulty of gathering sufficient graphene without compromising its electronic properties still have to be overcome. The Northwestern researchers printed the ink in 14 nm thick layers to make up precise patterns. Conductivity remained virtually unchanged, even when severely bent, indicating that graphene inks could, in future, be used to make foldable devices. In another development, workers at MIT in the US, have suggested a system that combines ferroelectric materials with graphene to create computer and data-storage chips that contain more components in a given area, are faster and less power hungry.

44 SEPTEMBER/OCTOBER 2013

The system would create a new way to build interconnected devices that use light waves such as fibre-optic cables and photonic chips with conventional wires and devices. At present, interconnection points form a bottleneck that slows data transfer and increases the component count. The MIT system works by controlling waves known as surface plasmons. The waves, at terahertz frequencies, are oscillations of electrons confined at interfaces between materials. The waves can be concentrated at much smaller-length scales which could lead to a tenfold gain in the density of components that could be placed in the given area of a chip. The system may create a new way of reading and writing electronic data into ferroelectronic memory devices at very high speeds. In another project, researchers are looking to produce the thinnest, most lightweight and efficient solar cell possible. Panels of one molecule thick materials such as graphene or molybdenum disulfide are at the heart of this work. Using two layers of material, it is predicted that cells with 1 to 2% efficiency could convert sunlight to electricity. This is a low conversion rate compared with the current 15 to 20% efficiency of silicon cells but the new material is just 1 nm thick, about 50 times thinner than silicon and weighs thousands of times less than silicon. Kilogram for kilogram the new cells produce up to 1000 times more power than present photovoltaics and, because the material is less expensive than silicon, only tiny quantities of material are needed.

NEXT-GEN ELECTRONICS

At the Ulsan National Institute of Science and Technology in South Korea, graphene has been combined with silver nanowires to form a thin, transparent stretchable electrode. This, it is claimed, overcomes the weaknesses of each individual material, producing a new class of electrode with possible applications in picture taking and scanning using soft contact lenses. The electrode points the way towards flexible displays, improved solar cells and electronics generally. Semiconductors grown on graphene are being researched at the Norwegian University of Science and Technology in Trondheim. While LEDs are superior in terms of energy efficiency, they are expensive to produce because of the costly semiconductor substrate. Semiconductor nanowires as graphene are expected to make it possible to construct LEDs that are cheaper and more efficient, more pliable and lighter than today’s devices.

GRAPHENE IS OPENING UP ALL SORTS OF ELECTRONIC POSSIBILITIES. IT IS A MATERIAL THAT IS INCREASINGLY BEING COMBINED WITH OTHER SUBSTANCES. THE THRESHOLD OF ITS POTENTIAL USES AND APPLICATIONS HAS ONLY JUST BEEN CROSSED.

Meanwhile in the US at Rice University and Oak Ridge National Laboratory, scientists have developed a method to control the growth of uniform atomic layers of molybdenum disulfide with the hope of joining it to graphene. If the union is possible, it will have hexagonal boron nitride added, which is an insulator, to create field effect transistors, integrated logic circuits, photodetectors and flexible optoelectronics. Graphene is opening up all sorts of electronic possibilities. It is a material that is increasingly being combined with other substances. The threshold of its potential uses and applications has only just been crossed.

STAND C35 CHIP RESISTOR The Vishay VCS1625ZP Z-Foil surface-mount, current-sensing chip resistor has a power rating of 1 W at +70°C and low TCR of ±0.2 ppm/°C typical from -55 to +125°C, +25°C ref. By dissipating up to 1 W in the 1625 package size, the resistor allows designers to use a single device to measure larger currents than previously possible. For high-power applications, the device offers tight tolerances to ±0.2% (0.1% and 0.05% are available) and a four-terminal Kelvin configuration for increased accuracy. The resistor features a power coefficient of 5 ppm at rated power, a thermal stabilisation time of <1 ns (nominal value achieved within 10 ppm of steady state value), and a wide resistance range from 0.3 to 10 Ω. Any resistance value within this range is available at any tolerance with no additional cost or lead time effect. The resistor offers a rise time of 1.0 ns with effectively no ringing, short time overload of <0.005% (50 ppm), current noise of 0.010 µVrms/V of applied voltage (<-40 dB), and a voltage coefficient of <0.1 ppm/V. The device withstands ESD to at least 25 kV and offers a non-inductive (<0.08 µH) and non-capacitive design. The Bulk Metal Foil technology of the resistor provides a significant reduction of the resistive component’s sensitivity to ambient temperature variation (TCR) and to the self-heating effect caused by changing loads. This allows designers to guarantee a high degree of stability and accuracy in fixed-resistor applications. In addition, the resistor’s design results in a very low thermal EMF of 0.05 µV/°C typical, which is critical in precision applications. The resistor’s load-life stability of 0.015% at +70°C for 2000 hours at rated power is an order of magnitude better than typical current sensing resistors. This makes it suitable for tightened-stability reference voltage and precision current sensing applications in forced-balance electronic scales, measurement instrumentation, bridge networks, motor controllers, and medical and test equipment. In addition, the resistor can be tested in accordance with EEE-INST-002 (MIL-PRF 55342) for military and space applications.

MEDICAL ELECTRONICS

Researchers from The Ohio State University have developed technology that will pave the way for lowcost electronic devices that work in direct contact with living tissue inside the body. The first planned use of the technology is a sensor that will detect the very early stages of organ transplant rejection.

ne barrier to the development of implantable sensors is that most existing electronics are based on silicon, and electrolytes in the body interfere with the electrical signals in silicon circuits, said Paul Berger, professor of electrical and computer engineering and physics at Ohio State. Other, more exotic semiconductors might work in the body, but they are more expensive and harder to manufacture. “Silicon is relatively cheap … it’s non-toxic,” Berger said. “The challenge is to bridge the gap between the affordable, silicon-based electronics we already know how to build, and the electrochemical systems of the human body. “We already have sensors that would do a great job at detecting these proteins, but they’re made out of silicon. So I wondered if we could come up with a coating that would protect silicon and allow it to function while it directly touched blood, bodily fluids or living tissue,” Berger said. In the body, electrolytes such as sodium and potassium control nerves and muscles and maintain hydration. They do this by carrying a positive or negative electric charge that spurs important chemical reactions. But those same charges make the electrolytes attractive to silicon, which will readily absorb them. Once inside, the charges alter the electronic behaviour of the silicon so that the readings of a sensor can’t be trusted. In the study, Berger’s team tested whether electrolytes could be blocked from entering silicon with a layer of aluminium oxide. The researchers submerged the coated test sensors in fluid for up to 24 hours, removed them from the solution and then ran a voltage across them to see if they were working properly. The tests showed that the oxide coating effectively blocked electrolytes from the solution so the sensors remained fully functional.

WWW.ELECTRONICSONLINE.NET.AU

Once developed, a device using this technology could detect certain proteins that the body produces when it’s just beginning to reject a transplanted organ. Doctors would insert a needle into the patient’s body near the site of the implanted organ. Silicon sensors on the needle would detect the protein and doctors would know how to tailor the patient’s dosage of anti-rejection drugs based on the sensor readings. The work represents a first step towards fabricating devices that could be implanted in the body long-term, Berger said. Though the current study describes a silicon sensor coated with aluminium oxide, he envisions that other devices could utilise coatings made from other materials such as titanium. Such coatings could even be tailored to boost the performance of sensors or other biomedical devices. In particular, Berger sees a potential use for coated polymer semiconductors that goes beyond sensing chemicals in the body. He suspects that such semiconductors could replace nerves in the body that have been damaged by disease or injury. “We could replace a damaged nerve with an artificial neuron and restore functionality immediately, and that’s a really exciting possibility,” he said. Berger’s team is working with Ohio State researchers Tom Rosol, professor of veterinary biosciences, and Phillip Popovich, professor of neuroscience, to explore that possibility. In a paper in the journal Electronics Letters, Berger and his colleagues describe a new, patent-pending coating that that they believe will bridge that gap. Co-authors on the paper included former doctoral students Anisha Ramesh, Fang Ren, Patricia Casal and Samit Gupta; current doctoral student in biomedical engineering Andrew Theiss; and Stephen Lee, associate professor of biomedical engineering. The university will license this technology for further development.

GIVING LIGHTING CUSTOMERS

WHAT THEY NEED

Paul Golata*

Over the past decade, LEDs have had an explosive growth in general lighting applications. LEDs offer great advantages over traditional lighting sources that include reliability, long life, reduced power consumption, small size, high efficacy and a high degree of design flexibility. LED manufacturers have been working diligently to increase creative design possibilities for customers, adapting products by incorporating a variety of packaging options. This article examines three major categories that play a key role in meeting customer demands for lighting.

hen people first think of lighting-class LEDs, they often think of a discrete high-power (1 W or greater) LED. A discrete LED is a single semiconductor diode that has been individually mounted into an appropriate thermalmechanical package. Ideally, discrete LEDs would be simultaneously bright and small. Footprint areas on these types of packages have been shrinking over time. Footprints of some commonly used packages in the recent past have been 12 mm2 and 6.3 mm2. LED manufacturers work to provide as much light-output power into the smallest possible package size. The constraining factor in discrete (singular LED) designs is often the thermal resistance (°C/W). LED packages with low thermal resistances allow better transfer of heat away from the die.

Discrete mid-power LEDs

In the last couple of years, many LED manufacturers have moved towards a new product category called mid-power LEDs, due to a high number of linear- and distributed-lighting applications. These packages are generally defined as LED packages, consuming somewhere in the 0.2 W to 1 W range (@ 3 VDC x [75 mA to 250 mA]). Mid-power products are often manufactured in similar footprint sizes to (yet in a different type of package than) their brighter (> 1W) LED brothers. Lower cost and lower total light-output power allow more LEDs per linear metre, thus achieving a smoother and more distributed lighting pattern that replicates the smooth visual output customers are used to.

Arrays

After LED manufacturers developed product lines of discrete LEDs, they quickly came to the conclusion that there would be many advantages to packaging multiple LED dies into a single thermal-mechanical package. One reason for this was the increased need for consistent correlated colour temperature (CCT) in general lighting applications. One benefit of an LED array is the ability for the LED manufacturer to control the mixing and matching of LED dies in a very small physical footprint, under the electrical control of one distinct package, and under the

optical control of one distinct window and/or lensing arrangement. Common variants of this configuration arose in many packaging arrangements, with the very common approach of one quad-die (4) in a single package.

Integrated (chip-on-board) arrays

As LED manufacturers continued to focus on customers’ end applications, they hit on another creative idea: integrated arrays or chip-onboard (COB) arrays. This takes the advantages of an array and moves it yet further by mounting the LED die directly onto the circuit board or substrate. This allows a unique packaging arrangement, enabling manufacturers to enclose the entire array with a phosphor-coated window. This ends up as high-efficacy, high-lumen output light from a single, integrated component. These encapsulated arrays are particularly attractive where high-lumen output from a single light source is necessary, such as bay lighting.

Modules

LED manufacturers have a goal to sell more LEDs. They recognise that many customers find it hard to take the requisite design steps that are necessary to be successful. To alleviate design issues, many LED manufacturers have continued to move up the customer design chain to offer comprehensive solutions for customers. Solutions often include combining LED, optical, electronic and mechanical features into a single product called a module. *As a Technology Specialist, Golata is accountable for driving the strategic leadership, tactical execution, and overall product line and marketing direction for solid-state lighting and other advanced technology products.

for higher-end data rich products. Electronic paper is considered to be more comfortable to read than conventional displays. This is due to the stable image, which does not need to be refreshed constantly, the wider viewing angle and the fact that it reflects ambient light rather than emitting its own light. A good e-paper display can be read in direct sunlight without the image appearing to fade. The contrast ratio in available displays is similar to that of newspaper, though newly developed implementations are said to be slightly better. E-paper is suitable for applications where the user needs minimal power consumption, such as battery-powered applications. These include electronic pricing labels in retail shops, general signage, timetables at bus stations, electronic billboards, mobile phone displays and e-readers capable of displaying digital versions of books and e-paper magazines. E-paper retains its image even without power for a long time (up to several years) and only consumes power during image updates and refresh. Images such as QR codes are also scannable. Sample e-paper displays and development kits are available from Glyn. An RF development kit for e-paper is also available.

INDUSTRIAL ETHERNET SWITCHES The Allen-Bradley Stratix 5700 managed industrial ethernet switch now includes an optional integrated network address translation (NAT) feature. The switches are currently available with six, 10 and 20 fixed-port configurations. The hardware-based NAT feature allows for high performance and simplified integration of IP-address mapping from a set of local, machine-level IP addresses to the end user’s broader plant-process network. The feature is said to greatly benefit manufacturers that are integrating identical machines into a production line, especially when multiple equipment builders are being integrated into a common production line. The NAT feature allows OEMs to deliver their standard machines to customers without having to program unique IP addresses into them. The end user can then use the NAT feature to more simply integrate the machines into the larger network. Because the machines are identical to their standards, they are easier to maintain. The switch also allows users to have the flexibility to segment or isolate network traffic by determining which devices are exposed to the larger network. The product includes features, such as IEEE-1588 time synchronisation, QoS (prioritisation) and Resilient Ethernet Protocol (REP). Each Stratix 5700 switch includes: dual-power inputs, input and output alarms, console port, fibre-ready SFP slots, DIN rail mount, and operating temperature range of - 40 to 60°C. Model options include: NAT, two gig ports, SD flash card, conformal coating, and two different software configurations for a total of 20 different models to best match machine and end-user applications.

s it just me or have you noticed that we are being taken over by American sounds and language? Slowly but surely, Americanese is invading our lives from voices over television advertisements to the prostitution of the written and spoken word. While, of course, English is a living language and must change with time, it is in mortal danger of becoming submerged beneath sloppy Americanese and SMS talk abbreviations leaving ‘pure’ English to the pens of poets - heaven forbid. American and Australian languages both come from the same English roots and both countries have developed their own specialised words, accents, dialects and meanings, but Australia is in danger of being smothered by the language from America. The way we speak may be similar and it was someone else who suggested that the greatest difference and the biggest divider between Australia and America is English. English is a vibrant enough communication medium and there is room for all branches of the language to develop independently without allowing it to submerge another branch. It is an insidious invasion and contamination. One of the widest abuses is the habit today of placing the emphasis of a word on the first syllable. Debris, adult, research, garage are common examples and there are many others. We now talk about, and regretfully recognise, “homicide” instead of “murder”, “autopsy” instead of “post-mortem”, “witness stand” instead of “witness box”, “off limits” rather than “out of bounds”. These examples of the invasion are only the tip of the iceberg. We talk about “stores” today rather than “shops” and “pharmacies” instead of “chemists”, and who today has heard of a grocer where supermarkets abound? And then there are the long, impressive words that have taken over from the simpler ones. Cases in point include “hospitalisation” rather than being “in hospital”, “transportation” instead of “transport”, “affirmative” rather than “yes”, “medication” instead of “medicine”. Our language now is in danger of becoming pompous and we haven’t even mentioned the spelling of words such as “analogue”, “programme”, “colour”, “plough”, “harbour”, “sceptical”, “sulfate” rather than the traditional “sulphate”, “leverage” that has long lost its mechanical meaning and the many other words that have become infected. And then there are the words that have changed completely so that today we talk about “antenna” for “aerial” and “ground” for “earth”. American-voiced television advertisements are so common that we accept them as the ‘norm’. Sometimes there is a token Australian voice-over but there are still TV channels blatantly devoted to promoting gadgets and equipment with voices straight out of the Bronx. Perhaps the most frequent are the ads for cinema films often delivered in a breathless pseudo dramatic voice. However, the regular television channels have more than their share of breathless deliveries all in the interests of pseudo drama. What about the long-held tradition of non-American pop singers who without exception adopt a phoney American accent for the lyrics - that is if you can follow the words at all as they try their best to swallow the microphone. Sadly, they follow a long line of copiers that goes back almost to the beginning of pop singing. What on earth is there in an Aussie accent to be ashamed of? And while we’re banging on about language, we cannot blame the Americans for the obsession we have for being politically correct and traditionally incorrect. The depths to which we have sunk are absurd. Manholes, mankind and presumably manhandled are out and the word “person” replaces the “man”. Even more ridiculous is the controller of a meeting who used to be called a chairman regardless of sex. Now it is the inelegant “chairperson” or, even worse, “chair”, which one assumes is good company for the table but when did a chair last run a meeting? Whatever happened to the dignified “madam chairman” or could this not be applied if the lady was unmarried? As earlier mentioned, English is a living language and Australia is as much a part of that family as England, Canada, America or New Zealand. Let’s preserve our unique special words, phrases and expressions for the next generation and beyond, if nothing else for words such as “cobber”, “digger” and the old-fashioned “sheila”.
