Conformal coating is a protective coating of thin polymeric film, applied to printed circuit boards (PCB). The coating is named conformal since it conforms to the contours of the PCB. Conformal coatings are typically applied at 25-250 μm to the electronic circuitry and provides it protection against moisture, dust, chemicals, and temperature extremities.

  • Conformal coating is a protective coating of thin polymeric film, applied to printed circuit boards (PCB). The coating is named conformal since it conforms to the contours of the PCB. Conformal coatings are typically applied at 25-250 μm to the electronic circuitry and provides it protection against moisture, dust, chemicals, and temperature extremities. Coatings can be applied in a number of ways, including brushing, spraying, dispensing and dip coating. Furthermore, a number of materials can be used as a conformal coating, such as acrylics, silicones, urethanes and parylene. Each has their own characteristics, making them preferred for certain environments and manufacturing scenarios. Most circuit board assembly firms coat assemblies with a layer of transparent conformal coating, which is lighter and easier to inspect than potting. (en)
  • 三防膠（Conformal coating）是印刷電路板上的透明聚合物薄膜，會維持印刷電路板的外形，並且保護印刷電路板上的電子元件。三防膠厚度一般會在25-250 μm（微米）之間。三防膠會保護電子電路，有防濕氣、防塵、防化學物質的效果。若電子設備運作在惡劣環境下，需要額外的保護，一般電路板會塗佈三防膠，而不是用來進行保護。 (zh)
