Abstract : This study was undertaken to define some of the mechanisms by which electronic equipment fails in field service and storage. Circuits were assembled under different controlled conditions and then exposed to humidity, salt fog and fungus growth. The properties studied included moisture absorption, moisture transmission, insulation resistance, leakage currents and electrical parameters characteristic of specific devices. Several conformal coatings (acrylic, epoxy, polyurethane and silicone) WERE COMPARED FOR THEIR ABILITY TO MAINTAIN RELIABLE OPERATION. (Author, modified-PL)
