Functional testing sample test instructions

Functional testing sample test instructions


HQ NextPCB can perform functional testing on PCBA orders for prototype, small batch and mass production volumes. To help you get an idea of what a functional test case looks like, we have prepared some examples below. Testing can be as simple as a power on test or full testing with a test jig and software controlled testing with firmware burning. Our test engineers can assist with fixture development to increase testing efficiency for larger batches.
