I guess these boards only used Fly test. Flying needle test is one of the methods to check the electrical function of PCB (short circuit test). The flight test machine is a system for testing PCB in a manufacturing environment. Instead of using the

Hi I am looking for some type of peelable mask or plug to cover the connector during the conformal coating. The problem we have is the moisture get into system and eventually penetrate under the connector creating short circuit to the board. What I r

I have used infrared imaging to find electrical shorts on logic boards between the 5 Volt buss and ground. You can power the electrical short up to draw 50 to 100 mA and then look for the warm spot in the infrared display.
