When to Use Conformal Coating Removal Services

Posted by Sean Horn on Fri, Dec 2, 2016

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:

Removing Conformal Coating Instead of Repairing It

Posted by Sean Horn on Fri, Nov 25, 2016

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 […]

Reapplying Conformal Coating After Its Removal

Posted by Sean Horn on Fri, Nov 18, 2016

Defects to either the PCB assembly or its conformal coating can be sufficient to cause coating removal.  Whether repair technologies address the circuit board’s components or the conformal film, subsequent post-repair coating (recoating) processes need to address:
