Functional Test Fixtures

Our experienced engineers will design an electro/mechanical solution to interface between your product and your test instruments. Circuit Check develops hot mock-up and custom stand-alone functional tests for circuit cards, backplane boards and card cage assemblies. We can develop tests for modules or fully assembled products such as cameras, cell phones, key fobs and palm top computers

We also provide hardware integration tools for optical sensing of LEDs, flash, LCDs or audio sensing for microphones and speakers.
