Failures in IoT PCB wire bond loops

Earlier we talked about wire bond testing for IoT printed circuit boards and the types of wire used to connect a bare chip to a substrate or the PCB surface itself. This discussion deals with wire bond loops pull testing and verification, which is critical for IoT device reliability.

Your immediate reaction is probably: What loops are you talking about? To the average everyday person, it would appear a wire goes from point A to point B in a straight line, right?
