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”
