What Is the Result of Negative Conformal Layer on PCBA?

Conformal Finish is an unavoidable part of the PCBA procedure. With the continual improvement of the high quality of PCBA items in the market, the demands for Conformal Coating are becoming greater and greater. As a result, it is extremely essential to select top quality Conformal Covering. However, some poor Conformal Layer will trigger a great deal of adverse impacts on PCBA. Next, we will certainly information the influence of poor Conformal Layer on PCBA.

1.Reduced Electric Conductivity

In the manufacturing of PCBA, the electrical conductivity of PCBA will certainly be lowered if the paint is not good. Particularly, the Conformal Covering may include some ions, such as sodium and potassium ions, which will disrupt the PCBA circuit, consequently impacting the normal circuit procedure. Furthermore, poor Conformal Layer can harm the PCBA metal line too, which will certainly lead to circuit interference or short circuit, thus influencing the typical operation of the tools.

2.Poor Rust Resistance

The fundamental feature of the Conformal Finish is to avoid PCBA from being harmed by moisture, deterioration, and other problems. Nevertheless, the rust resistance of a negative anti-corrosion paint is even worse than that of a great anti-corrosion paint, which implies that PCBA will be easily corroded. If the PCBA is corroded, the steel electrical wiring will be harmed, which will certainly interfere with the regular operation of the equipment.

3.Heat Dissipation Performance Is Affected

A big amount of warmth generated by PCBA producers at work needs to be dissipated, otherwise prompt warm dissipation, it will certainly damage the circuit and also influence the safety of the tools. A great Conformal Layer has the features of excellent warm dissipation performance, which can help PCBA much better heat dissipation. Nonetheless, the negative Conformal Coating will certainly affect the heat dissipation efficiency of PCBA, causing high circuit temperature level, therefore affecting the normal procedure of the tools.

In general, Conformal Finishing will certainly bring a great deal of negative results to the PCBA spot, hence influencing the typical operation of the equipment. As a result, it is very vital to select high-quality Conformal Finish, which can make sure the quality and security of PCBA.
