PCB conformal coatings for G1/G2/G3 compliances are specialized protective coatings designed to shield printed circuit boards (PCBs) from environmental stress, moisture, corrosion, chemical contaminants, and electrical failure. These coatings comply with the International Electrotechnical Commission (IEC) standard IEC 60068-2-60, which outlines the environmental testing for electronic components.
G1, G2, and G3 represent increasing levels of environmental severity:
