If problems in a conformal coating defy reliable repair, coating removal may be the only solution. Removing conformal coating from PCBs requires matching removal methodology with coating type and the component’s function. A variety of factors – bubbles/voids, coating thickness, component failure, inadequate masking, poor adhesion, surface finish, among many others – can necessitate coating removal.Read More

Conformal coatings protect printed circuit boards (PCBs) and similar electronic assemblies used for a wide range of aerospace, automotive, consumer, defense and medical applications. Coatings effectively cover PCBs, shielding them from contaminants, liquid incursions, temperature fluctuations and other conditions potentially hazardous to component performance. However, problems can develop if their preparation, application, and drying processes are inappropriately managed.Read More

Conformal coatings frequently play a critical role in protecting medical, electronics, defense, aerospace, LED, and automotive applications from contaminants and other potentially hazardous substances. But they're not infallible.
Last week, we discussed what the causes of bubbles in conformal coating are. Now, let’s go through the various ways to remedy the bubbles.
