The three-proof paint is coated on the surface of the circuit board to form a layer of three-proof protective film (three-proof refers to anti-moisture, anti-salt spray, and anti-mildew). Under conditions such as chemical substances (for example: fuel, coolant, etc. Its system can accurately identify safety hazards such as power equipment failure, oil and gas pipeline leakage, and railway track. Currently, there are three main types of three-proof processing technology that I know about PCB circuit boards: three-proof paint, electronic wax, and nano-coating. The three proofing paint for PCBs, also known as the three proofing paint for PCBs, is a specially. A three-proof coating, also known as a conformal coating, is a specialized polymeric layer applied to printed circuit board assemblies (PCBAs). As the name implies, its primary function is to “prove” or protect against: Moisture and Humidity: The coating forms a hydrophobic barrier, preventing. Electronic processing in the "three anti-" nature of the protected surface is coated with a layer of protective film, the protective effect of the coating method, coating process. Spraying basically belongs to the protection of the PCB surface, dip coating can protect the components.
