Has anyone ever encountered contaminants from the immersion silver process, whether it be from the board house or not...as it relates to conformal coating. The failure mode is severe de-wetting of acrylic conformal coating. All over solver resist, tops of components, pretty much everywhere on the assembly. Possibly some kind of sulphur contamination?
