Cleaning is crucial in PCBA OEM material processing, as it can remove surface dirt and residues, enhance insulation performance, improve corrosion resistance and appearance quality。

1. Cleaning can effectively remove dirt and residue from the surface of PCB boards
During the PCBA processing, there may be residual solder slag, solder paste, oil stains, and other substances on the PCB board. If these substances are not thoroughly removed, they will have adverse effects on the performance of the PCBA. For example, solder slag or solder paste may cause a short circuit or open circuit in the circuit, while oil contamination may hinder the electrical continuity and conduction of the circuit. Therefore, cleaning is a key step in ensuring stable and reliable performance of PCBA.
2. Cleaning can improve the insulation performance of PCB boards
With the development of electronic products, the lines on circuit boards are becoming increasingly dense, resulting in shorter distances between the lines. If not cleaned during the processing, residues may form conductive channels, leading to short circuits between circuits. In addition, residues may also cause a decrease in the dielectric strength of the circuit board surface, increasing the risk of circuit board breakdown. Therefore, cleaning is crucial for ensuring the insulation performance of PCBA.

3. Cleaning can also improve the corrosion resistance of PCBA
During the processing, PCB boards may be contaminated by chemicals such as acid and alkali. If not cleaned in a timely manner, these pollutants will corrode the circuit board. Corrosion not only causes oxidation on the surface of the circuit board, but also damages the conductivity of the circuit. After thorough cleaning, pollutants can be effectively removed, the corrosion resistance of PCBA can be improved, and the service life of the circuit board can be extended.
4. Cleaning can also improve the appearance quality of PCBA
Electronic products, as important consumer goods in terms of appearance, have a crucial impact on the consumer experience in terms of their appearance quality. If there is dirt or residue on the surface of the circuit board, it will affect the aesthetics of the product. By cleaning, the appearance of PCBA can be made cleaner and neater, improving the texture and appearance quality of the product, and enhancing its market competitiveness.
