The PCB conformal coating process involves applying a protective layer to printed circuit boards (PCBs) to safeguard them from environmental hazards like moisture, dust, chemicals, and temperature extremes. This coating enhances the durability and reliability of electronic components, particularly in demanding applications. Common coating materials include acrylic, silicone, urethane, and epoxy, each offering specific benefits such as flexibility or chemical resistance. Application methods include spraying, brushing, dipping, and selective coating, chosen based on the PCB design and production scale. After application, the coating is cured using UV light, heat, or air drying. Proper masking of sensitive areas ensures functionality while providing robust protection.
