I have some boards that are coated with acrylic conformal coating. We have to do a few chip replacements. The coating will be selectively stripped around the chips and the rework performed. Is there a problem with sending a coated board through an in-line aqueous cleaner? I am running just water at 130 degrees F. Will the pressure damage the coating? Will the water recycling system become contaminated? Do I have to strip the board completely prior to rework to avoid any problems? Thanks for your help.
