What is the result of negative Conformal Finish on PCBA?

Conformal Finishing is an inescapable part of the PCBA procedure. With the continuous renovation of the
high quality of PCBA items in the market, the demands for Conformal Finishing are ending up being
greater and greater. As a result, it is really important to pick high-grade Conformal Covering.
Nonetheless, some negative Conformal Layer will create a great deal of unfavorable effects on PCBA.
Next, we will certainly detail the impact of bad Conformal Finishing on PCBA.

1. Decreased electric conductivity

In the production of PCBA, the electrical conductivity of PCBA will certainly be lowered if the paint is
bad. Particularly, the Conformal Coating may have some ions, such as salt and potassium ions, which will
certainly disrupt the PCBA circuit, consequently affecting the regular circuit procedure. Furthermore,
inadequate Conformal Layer can damage the PCBA metal line as well, which will certainly cause circuit
disconnection or short circuit, therefore impacting the regular procedure of the equipment.

2. Poor rust resistance

The basic feature of the Conformal Finish is to prevent PCBA from being damaged by dampness,
deterioration, and other problems. Nonetheless, the corrosion resistance of a bad anti-corrosion paint
is even worse than that of an excellent anti-corrosion paint, which suggests that PCBA will certainly be
easily rusted. If the PCBA is rusted, the metal wiring will certainly be harmed, which will disrupt the
regular procedure of the equipment.

3. Warmth dissipation efficiency is impacted

A big quantity of warm created by PCBA manufacturers at the office needs to be dissipated, otherwise
timely heat dissipation, it will certainly damage the circuit and also affect the security of the tools.
A good Conformal Covering has the attributes of excellent warm dissipation performance, which can help
PCBA far better heat dissipation. Nevertheless, the negative Conformal Layer will certainly affect the
heat dissipation performance of PCBA, causing high circuit temperature, therefore affecting the normal
procedure of the tools.

Generally, Conformal Coating will bring a great deal of negative impacts to the PCBA
spot, thus impacting the normal procedure of the tools. Therefore, it is extremely essential to pick
premium Conformal Finishing, which can make certain the quality and stability of PCBA.
