Electronics Testing
ICT (In-Circuit Testing)
ICT is a type of testing performed directly on PCB to check each component for open / short circuits, incorrect part placement. Method:
- Build a “bed-of-nails” fixture that includes test points, probes
- The fixture measures resitance, voltage, capacitance
So it’s quick, good test coverage, automated. but it can’t test the high level features.
Functional Testing
Test the system’s overall performance, such as communication, user interfaces, power distribution.
