TECHNICAL BRIEF Resist Stripping — A Simple Process?

The stripping of resist after imaging the circuit pattern is an important part of PCB manufacturing. Resist Strippers are generally operated on a ‘Run and Dump’ basis which means the stripping speed is always changing. In an attempt to make the process more controllable and to improve process yields a resist stripper was formulated which strips fast and can be controlled to give a constant stripping speed.
