You wouldn’t think that batteries could fail radiated immunity testing, but today’s more sophisticated Li-ion battery packs include battery management system (BMS) circuitry that monitors the ...

A tough challenge for test engineers is explored in terms of test methods, pitfalls, and measurement errors. For the test engineer, RF and microwave power amplifier testing imposes unique challenges.

Far-field and radiating near-field are two options for high-volume over-the-air (OTA) testing of antenna-in-package (AiP) modules with automated test equipment (ATE) [1]. In this article, we define an ...

Before we delve into a step-by-step guide to good engineering practice, two thoughts to keep in mind. First, there are too many subpar test reports from engineers, who often do excellent work but aren ...

Relays are electromechanical devices that use a magnetic solenoid to actual a switch. When current is passed through the solenoid coil, it produces a magnetic field. The magnetic field is strengthened ...

People tend to spend, on average, several hours a day sitting on couches, chairs, and car seats, as well as considerable time on mattresses every night. Polyurethane foam plays a major role in ...

Wire bonding is widely used in electronic devices, the semiconductor industry, and microelectronics. It enables interconnections between the die and other electronic components in an integrated ...
