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 ...

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 ...

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 ...
