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.

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.

Parylene  is often applied to substrates or materials where there is no room for any voids in the protective coating.  These materials are likely to be placed in harmful chemicals, a moisture packed environment, or even the human body.  These are often mission critical devices which can not allow any environmental factors to alter their performance.  Whenever these devices need this stringent level of protection from the elements, parylene is the only logical choice.

One of the causes for failure during conformal coating inspectionare bubbles.  Bubbles are trapped pockets of air under coating.  The bubbles can cause voids in the coating and Here we will identify the six largest causes of bubbles.
