Why does PCBA circuit board need conformal coating?

PCBA Circuit Board Conformal Coating is a coating for electronic equipment that provides protection against water, dust and corrosion. It is a specially designed coating that forms a protective coating on PCBs (Printed Circuit Boards) to protect key components of electronic equipment from adverse environmental conditions and chemical contamination, and is resistant to aging, radiation, salt spray, ozone corrosion, vibration, good flexibility, strong adhesion and other properties.

In modern electronic equipment, Conformal Coating not only plays the role of aesthetics, but more importantly, its protective function. Under unfavorable environmental conditions, Conformal Coating can prevent the penetration of harmful substances such as water vapor, gas, dust, corrosion and electromagnetic interference, thus protecting the operational status and life of electronic components and PCB circuit boards.

In addition, Conformal Coating for PCBA circuit boards can also improve the performance indexes of PCB circuit boards such as impedance, voltage resistance and insulation. It can also resist the effects of the external environment such as sunlight, heat, vibration and mechanical pressure, effectively extending the service life of electronic equipment. There are also human factors, such as fingerprints, body fat, these factors later will lead to the use of the product instability, in the circuit board coated Conformal Coating, can reduce the use of electronic products performance reduction.

In conclusion, the role of Conformal Coating on PCBA circuit boards is very important, and it has a significant protective effect on the long-term operation and stability of electronic equipment. Therefore, Tecoo Electronics Co., Ltd carries out sufficient quality control and inspection of the triple-proof varnish during the production and assembly of PCB circuit boards to ensure its quality and effectiveness.
