Today’s high power semiconductor test applications are increasingly demanding, requiring test instrumentation capable of characterizing higher rated voltages and peak currents than ever before. Many ...
Test and programming fixtures are great time-savers for anyone who needs to deal with more than a handful of PCBs. Instead of plugging in connectors (or awkwardly holding probe tips or wires) to ...
When asked, many engineers will say that the goal of a test plan for a PCB is full or 100% test coverage. When pressed further, they usually admit that 100% test coverage is virtually impossible to ...
Over the last decade, there has been a move away from powered-up digital in-circuit vector testing to unpowered analog-based (vectorless) device-pin opens testing for large and sometimes small digital ...
Test and programming fixtures are great time-savers for anyone who needs to deal with more than a handful of PCBs. Instead of plugging in connectors (or awkwardly holding probe tips or wires) to ...
I noted in a 2005 column (see "Current compression test methods" under “Editor's Pick,” at top right) that there are three basic methods of loading a composite material test specimen in compression: ...
Flexural strength and stiffness are not basic material properties. They are the combined effects of a material’s basic tensile, compressive and shear properties. That is, when a flexural loading is ...
Older folks may recall the famous Tektronix 576 and 577 curve tracers from half a century ago. A few of these have survived the decades and ended up in some lucky engineer’s home/work lab. Wow the ...
