Masking For Conformal Coating Printed circuit boards (PCBs) and related electrical assemblies benefit from the protection of conformal coatings. However, because the films are insulative when dry, they can disrupt operation of the assemblies’ electrical components, items like capacitors, connector contacts, diodes, operational amplifiers, resistors, or transistors. Conformal coating masking
It is possible to remove unwanted conformal coatings from PCBs in-shop. The process can often be accomplished by either the assembly’s original equipment manufacturer (OEM) or an end-user, but the capacity to do so doesn’t always exist. For these parties, conditions affecting the poor coating may:

Sometimes problems with conformal coating are too complicated or difficult to repair. This can occur when bubbles develop in the coating during the application process; bubbles cause voids in the coating that defeat its protective, insulating purpose, suggesting the need for removal. Other situations that lead to inadequate coverage, and may favor coating removal, rather […]
