Redefining Benchtop ATE with Mixed-Signal IO Systems
Publication Date: 7/1/2016


Many digital electronics designs now contain some form of JTAG/boundary-scan to aid structural board testing or in-system device programming. However, accessing the JTAG feature in a reliable and repeatable manner has always been somewhat neglected by boundary-scan technology and programmable ...

Smart Assembly and Test in Cable and Harness Manufacturing
Publication Date: 7/1/2016


Since quality and productivity are the main priorities in cable and harness manufacturing, test engineers typically turn to PC-based cable and harness testers. PC-based systems are operated by an autonomous (rather than embedded) computer and offer superior flexibility when developing ...
Soldering for Aerospace's Harsh Environment
Publication Date: 7/1/2016


Environmental conditions are harsh at the edge of space. The temperature is extremely cold, reaching -50°C (-58°F) and ultra-low air pressure of 240 hPa at altitudes above 10,000 meters (33,000 feet). Winds whip at speeds up to 190 mph (300 kph) in the jet stream. Aircraft ...
The Transition to Flexible Automation
Publication Date: 7/1/2016


If implemented correctly, automation can help a company scale its demand requirements, reduce and fix production costs, improve quality, eliminate health and safety issues, and most importantly, realize a more substantial ROI faster and more efficiently.
Top-Side Preheat and Avoiding Board Warp in Selective Soldering
Publication Date: 7/1/2016


Closed-loop top-side preheat generally refers to any preheating unit that presents energy from above the PCB and is used for heating the board to a specific temperature, as well as holding it at this value throughout the process. The system must include some form of temperature measuring ...
Wearables for Health: Hybrid Electronics with Medical Sensors
Publication Date: 7/1/2016


In an effort to meet the growing demand for hybrid electronics production, a team at the Fraunhofer Institute for Silicon Technology in Germany has been developing prototypes of hybrid electronics systems. The focus is on the combination of both silicon and flexible electronics manufacturing ...
A Solution for Press-Fit Pin and Receptacle Applications
Publication Date: 6/8/2016


Press-fit pins and receptacles are among the most versatile types of interconnection components for electrical and electronic applications. As with other types of pins and fasteners, they play an integral role in product quality, but are easily taken for granted. For example, the fasteners ...
Demystifying the Magic of Plasma Treatment
Publication Date: 6/8/2016


Plasma is a state of matter, differing from the gaseous state in that it can conduct electricity. When sufficient energy is added to a gas, some atoms and molecules eject an electron, ionizing the gas into an electrically conductive state. The energizing source is normally an oscillating ...
Infrared Technology Brings the Heat
Publication Date: 6/8/2016


Infrared heating technology has become prevalent among the industrial ovens, dryers and heaters used by a multitude of manufacturers. The OEMs that manufacture these ovens and heaters use infrared heating elements, which are more energy efficient, cheaper to operate, provide controllable ...
JTAG and Boundary-Scan — Past, Present and Future
Publication Date: 6/8/2016


Almost 30 years ago, the change in device packaging from through-hole to surface-mount prompted a group of production test engineers to consider the impact of these parts on the testing of their assemblies. They called themselves the Joint European Test Action Group (JETAG) and were ...
Next Generation Product Designs Incorporate Capacitive Force Sensors
Publication Date: 6/8/2016


Design engineers now have an option to evaluate and integrate into their products a new breed of capacitive technology-based sensor that can accurately, and with high repeatability, measure forces as low as 1 gram.
Product Highlight: Hasco's Critical Relays
Publication Date: 6/8/2016


Electromechanical relays, which had been widely used in the past by the telecom industry, today have a wide range of applications in high-reliability industries like aerospace, automotive and defense. They are used in fire safety devices, lighting controls, sensors, HVAC, and all sorts ...
The Advantages of Digital Signal Processing in Power Converters
Publication Date: 6/8/2016


The power electronics industry is increasingly moving from analog to digital power converters, particularly when high-density power output is required. Many mission-critical operations in aerospace and defense, as well as in some industrial applications, require output power in the ...
Surface-Mount Components Help Shrink Circuit Dimensions
Publication Date: 6/8/2015


Surface-mount components have earned their places in today's electronic circuits, saving a great deal of printed-circuit-board (PCB) space without sacrificing the performance of much larger components. Components now available in SMT housings include basic "building-block:" components ...
The Benefits of Using Aluminum as a Conductor
Publication Date: 6/8/2015


Choosing conductive metals for different industries and applications is often a challenge. Copper is often used in cables and wires for its excellent conductivity and malleability. But it is relatively heavy and expensive compared to aluminum. Switching to aluminum, which is lighter ...
Unwired Switches Are Wireless Without Batteries
Publication Date: 6/8/2015


Switches that operate without wired connections or batteries are now available from Cherry, a brand of ZF Electronic Systems Pleasant Prairie, LLC. The switches use the physical actuation of the switch as the source of power, harvesting energy through an innovative penny-size micro ...
Vibration Testing: Exposing the Weak Link
Publication Date: 6/8/2015


Weak links exist in all electronic designs. Over time, and in the right conditions, they will manifest themselves. Vibration testing attempts to uncover those weak links in advance by imposing realistic operating conditions. By developing a circuit card assembly (CCA) for testing, it is ...
