Recently I completed a process evaluation on various stencil / misprinted PCB cleaning systems. They were both ultrasonic (theoretically can damage PCB�s) and the more conventional method of high pressure rotary bar method. I found that the best sys

What flux are you using to put them back on? you should be able to adequately clean the site after removal with alcohol or water depending upon the type of flux. "White grungy" usually comes from a liquid flux such as Alpha 857 being squirted on th
