| How do I mechanically/visually inspect BGA devices when they are soldered to a PCB for possible solder, or other, defects as a first step before part removal and further analysis? I have had board failures due to poor soldering--I think? I can pr

| | I have gold fingers that I want to mask when running over the wave without pallets. They're on the leading edge of the board. I recall seeing rubber boots that slid onto the fingers to mask them. Pop 'em on before the wave; pop' em off after a

| Hello: | BACKGROUD: SMT components soldered on the top-side of boards that also require wave soldering have the potential to reflow during wave soldering. Reflowing these components during wave soldering is not good. It can cause cold joints, op
