Ask The Expert: Chris Palin Humiseal, Conformal Coating Materials on Key Conformal Coating Inspection Challenges

“The UV brightener used in conformal coatings can vary from different coating manufacturers. The variation is due to volume or type of brightener used. Generally speaking a high brightness UV tracer will  aid the automatic inspection system to identify that correct coating areas are covered and also look for stray material that may have entered critical keep out areas.”

“Some conformal coatings do not contain UV tracer and this is usually for a reason such as coating over LEDs or optical sensors where the UV tracer could affect light transmission. UV brighteners degrade over time with exposure to UV light therefore the coating on older PCBs may not show up quite as well depending on time and physical location of the board during its operational lifetime.”

Ask The Expert: Dr Lee Hitchens, Nexus on Key Conformal Coating Inspection Challenges

“Considering the Key Inspection Challenges faced by users, then continuity of what people actually require in terms of quality of finish is the biggest problem for conformal coating inspection. Using the standards available are fine but many companies don’t really read them and actually don’t understand them fundamentally.”
“For instance, is it really okay to have debris on the surface of a conformal coated PCB? The IPC IPC-A610 Acceptance Standard states it is okay as long as the, “Foreign material does not violate minimum electrical clearance between components, lands or conductive surfaces”. I guess that most would not consider this okay cosmetically even if technically and electrically this is fine. This discrepancy in understanding is key to inspection”
