Abstract
A novel photoresist stripping process is disclosed. Specifically, it has been found that if a printed wiring board panel having photoresist on its surface is used as a cathode during electrolysis in an alkaline solution, the result is a rapid and complete photoresist removal with minimal sheeting of removed photoresist and no evidence of chemical attack upon metallic traces on the printed wiring board.
