We have made numerous circuits which have to operate continuously in oil. The best designs use an all polyimide system including the base material as well as the covercoats.

I am looking for information on circuit boards operating in oil. The application would be a flex/rigid board with SMT components on it operating in a hydraulic pump. I am wondering if there is any experience on the affects of the oil on the components, solder and the board. Any information would be greatly appreciated!!!
