Abstract

The protective properties of coatings for are generally Printed Circuit Board (PCB) evaluated by means of accelerated degradation laboratory tests, including electrochemical techniques. There are common four kinds of coating of printed circuit board that the materials of the coatings are parylenec, acrylic, polyurethane, silicone. In this paper, we designed an accelerated degradation test of humid and heat for these four kinds of coatings. The coatings were tested in the laboratory using insulation resistance, in order to quantify the damage, after accelerated degradation test. Finally, the reliable lifetime of the coating is predicted by an accelerated degradation model Accelerated Model (AM).
