APPROACH ON THE PREVENTION AND METHODS OF ELIMINATING DEFECTS OCCURRING IN THE SELECTIVE COATING PROCESS USING A 1K MATERIAL

Gergo-Norbert BOCZOR, Domnița-Florina FRĂȚILĂ, Adrian Constantin POPESCU

Abstract


For almost any power electronic systems, the basic infrastructure consists of Printed Circuit Boards (PCBs). High Performance electronic products often include conformal coating materials to protect printed circuit assemblies from moisture, dirt or other detrimental environmental hazards and, also, to provide durable insulation for reducing thermal and mechanical stress on the components and to reduces the risk of electrical shorts and leakage currents. In this study, PCBs with conformal coating of 1K material were examined. A significant part of conducted research is concentrated in the development of the specific methods for these coatings diagnostics and defects prevention.
