A grid testing machine has three building blocks - a fixture, a bed of nails and software, to control the overall functionality of the machine. It usually has two cameras which are placed on the top and bottom of the machine in order to scan the whole board.
Advantages of PCB Grid Testing:
Limitations of PCB Grid Testing:
This type of testing is called In-Circuit Testing. Another test process used for In-Circuit testing is Flying Probe Testing.
