At my previous job I tried to remove parylene using a plasma etching process. I don't remember the parameters used, but I do remember this: we had almost no success in removing parylene using plasma etching. I'd be quite interested in hearing if y

We have done it before prior to conformal coating a customer's populated board with parylene. They had us do a sample first then conducted testing. No ill effects but it really comes down to the components installed and what they can handle. The surf
