Ask The Expert: Karl Hardcastle, SCH Services Ltd, Subcontract Conformal Coating Service on Key Conformal Coating Inspection Challenges

“One of the interesting points is not all conformal coating defects and problems show up under UV light. You really need to inspect your PCB under white light and UV light to check for different defects. What can look like a perfect coating under UV can cosmetically look awful under normal daylight!”

“Also, you cannot tell how good coating adhesion is with visual inspection only. We examine the PCB as a coating service and if it looks good that’s fine. but without testing we cannot tell how well the conformal coating has adhered.”
