How to Remove Conformal Coatings

Posted by Sean Horn on Fri, Aug 18, 2017 @ 07:30 AM

Appropriately selected and applied, conformal coatings provide essential working protection for printed circuit boards (PCBs). However, removal of conformal coatings is necessary if the wrong coating material is selected relative to the PCB’s functional requirements, inadequately supporting its operating environment. Poor coating application can trigger failure mechanisms within the assembly, also calling for its removal and re-application.

Conformal Coating Removal Standards

Posted by Sean Horn on Fri, Feb 17, 2017 @ 08:00 AM

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.

When to Use Conformal Coating Removal Services

Posted by Sean Horn on Fri, Dec 02, 2016 @ 07:33 AM

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:
