Conformal Coating is applied to flexible circuit boards. In addition to the role of protection, it also has the effect of insulation on the electronic PCB board (Insulation, moisture-proof, dust-proof). Such as vehicle parts, solar energy, LED street light ships, electronic scales, GPS, anti-theft devices, industrial computers and outdoor products for insulation and moisture resistance. It can penetrate deep into small gaps to make the waterproof effect better. After coating it can be moisture-proof and dust-proof, protect electronic components, and extend the life of parts. The coating method is spraying method, soaking method, partial brushing method. Lihsi’s products are in compliance with ROHS environmental protection regulations and UL94V-0 flame resistance rating.
