The company’s dispensing robot, complete with a brush applicator and suitable valve system, is a proven method of automatically applying conformal coating to PCB areas surrounding contacts that may be sensitive to possible spray contamination. Trials for an in-flight PCB conformal coating application proved that applying the coating material with a robot-controlled precision brush and the company’s valve improved quality, reduced setup time, gave repeatable results, and saved $75,000 in systems costs. Time spent covering contacts with protective cups was eliminated and postassembly dismantling and cleanup avoided.
