Bare Board Test (BBT) is an essential process in the printed circuit board (PCB) industry that involves testing unpopulated PCBs for shorts and opens. During this test, the PCB is examined for unintended connections between points that should not be connected, known as shorts, as well as missing connections between points that should be connected, known as opens. The primary objective of the Bare Board Test is to ensure the quality and functionality of the PCB before components are added.
