As the size of PCBA and electronic components becomes smaller and the density becomes higher, the distance between the device and the PCB is also reduced, and the influence of environmental factors on the PCBA is also increasing. Therefore, higher requirements are put forward for the reliability of PCBA of electronic products.

PCBA conformal coating can effectively achieve the protection effects of insulation, moisture, leakage, shock, dust, salt spray, etc., thereby improving the reliability of the circuit board, increasing its safety, and effectively extending the service life.

PCBA conformal coating is widely used in high-tech fields, such as high-end circuit boards in automobiles, home appliances, military electronics, aerospace, medical electronics, etc. It can improve the quality of PCBA products and effectively reduce the number of repairs. In addition, the rise of emerging industries, such as charging piles for electric vehicles and unmanned aerial vehicles, has further expanded the scope of the use of three anti-paints. At present, it has become a major trend to paint conformal coating on PCBA for protection.

Conformal coating is used to protect PCBA and its related equipment from environmental erosion. Conformal coating process is a necessary process link in production.

The coated conformal paint protects electronic products from external factors such as extreme heat, humidity, moisture and dust. At the same time, it can also protect electronic products from internal factors such as corrosion, whisker growth, and short circuits in the system. In short, the conformal coating is equivalent to an insulating layer to ensure the normal operation of different components and avoid premature failure of the PCB.
