Cover and ESD Protection for Shielded Fixture Kits


INGUN's fixture kits are well-known for their ease of operation and cassette design. Expensive dedicated fixtures can only cover one device under test (DUT). INGUN's fixture kits can be reused for several devices — simply by swapping out the insert, while keeping the same frame and ...

Enhanced Manufacturing Services 4.0 Part 2: NPI Driven by Test Coverage


The purpose of any test solution is to maximize test coverage, ensuring that the majority of defects are detected, while minimizing the test cost. If a product is not tested well enough, poor-quality products can be devastating to a manufacturer's reputation. If a product is tested ...

Evaluating EMS Providers from Two Angles: Supply Chain and Engineering


The ideal contract manufacturer is more than a transactional supplier, but a partner who improves both the product and process. When OEMs outsource PCBs or electronic box build assemblies, the primary criteria when selecting a contract manufacturer have always boiled down to cost, quality ...

New Solder Attach Technologies Streamline Application-Specific Assembly


Manufacturers have been pre-tinning component solder leads for years, but mostly for through-hole technology. SMT and lead-free soldering have made this type of preparation difficult, until now.

Reliability Fundamental to the Reed Relay's Long Success


A reed relay, if used correctly, is a near-perfect device with a low-resistance metallic switch path and inherent isolation between the control voltage operating the coil and the signal being switched. Reed relays contain a reed switch, a coil for creating a magnetic field, an optional ...

The Case for PC-Based Machine Control over Traditional PLCs


Over time, PC-based machine control has encroached upon, and ultimately gained dominance over, traditional, reliable PLC (programmable logic control) controllers. There are many different reasons, but perhaps the most important benefit directly attributable to this development has been ...

Redefining Benchtop ATE with Mixed-Signal IO Systems


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 ...

Soldering for Aerospace's Harsh Environment


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 ...

Top-Side Preheat and Avoiding Board Warp in Selective Soldering


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 ...
