Conformal Finishing is an inescapable part of the PCBA procedure. With the continuous improvement of the quality of PCBA items on the market, the needs for Conformal Covering are becoming higher and higher. As a result, it is very important to select premium Conformal Layer. Nonetheless, some poor Conformal Layer will certainly create a lot of negative impacts on PCBA. Next, we will detail the effect of poor Conformal Covering on PCBA.
1.Decreased electrical conductivity
In the manufacturing of PCBA, the electrical conductivity of PCBA will certainly be lowered if the paint is not good. Particularly, the Conformal Finishing might have some ions, such as salt and potassium ions, which will disrupt the PCBA circuit, therefore influencing the typical circuit procedure. In addition, inadequate Conformal Covering can harm the PCBA metal line also, which will certainly bring about circuit interference or short circuit, thus influencing the normal procedure of the equipment.
2.Poor deterioration resistance
The fundamental function of the Conformal Layer is to prevent PCBA from being damaged by wetness, rust, and various other problems. Nevertheless, the deterioration resistance of a negative anti-corrosion paint is even worse than that of an excellent anti-corrosion paint, which means that PCBA will be conveniently rusted. If the PCBA is corroded, the metal circuitry will be harmed, which will disrupt the typical operation of the devices.
3.Warmth dissipation performance is impacted
A huge quantity of heat created by PCBA producers at the office needs to be dissipated, if not prompt warm dissipation, it will harm the circuit and even impact the security of the tools. An excellent Conformal Layer has the attributes of good warmth dissipation efficiency, which can aid PCBA better warmth dissipation. Nevertheless, the poor Conformal Finishing will influence the warmth dissipation performance of PCBA, causing high circuit temperature, thus impacting the normal procedure of the tools.
As a whole, Conformal Layer will certainly bring a lot of unfavorable impacts to the PCBA patch, hence impacting the typical operation of the tools. As a result, it is really important to select top quality Conformal Coating, which can make certain the quality and security of PCBA.
