Conformal coating inspection solutions help manufacturers verify that protective material has been applied where it is required. They address checks such as coverage, keep-out areas and, with the appropriate measurement method, coating thickness.
Visual inspection under suitable lighting can reveal missed regions and unintended coating on connectors or contact surfaces. Fluorescent coatings may be assessed with appropriate illumination, while automated optical inspection supports repeatable coverage checks. Thickness and cure condition require methods chosen specifically for those characteristics.
Inspection criteria should account for the PCB design, component shadowing and the coating specification. A clearly defined reference pattern helps operators distinguish an acceptable edge from a genuine omission. Recorded results can also support investigations into application changes, material variation or recurring defects. Inspection works best as part of a process that includes preparation, controlled application and suitable curing.
