N2 - In this paper, four kinds of coating (acrylic coating, polyurethane coating, silicone coating, ParyleneC coating) on printed circuit board have been studied in terms of moisture absorption, insulation resistance and surface morphology by fungus test, salt fog test and humidity test. The results show humidity test has largely effect on coating than salt fog test; the smallest effect is fungus test. ParyleneC coating is the best material by the three corrosion test, the second is silicone coating, the third is polyurethane coating, and the last one is acrylic coating. What is more, the weakest parts on acrylic coating are the edge of the solder paste, through-hole and so on.
