During the PCB assembly process, solder paste and flux residue can form residual chemical substances, including organic acids and decomposable ions. Organic acids have corrosive effects, and residual ions on the solder pads may cause short-circuit faults. Moreover, these residues on the PCB are particularly dirty and do not meet the cleanliness requirements of customers.…

The process of water cleaning for PCBA (Printed Circuit Board Assembly) boards involves using water as the cleaning medium, with the addition of small amounts (typically 2% to 10%) of chemical substances such as surfactants and corrosion inhibitors. The cleaning process includes washing, followed by multiple rinses with deionized or purified water, and drying to…

The principle of PCBA board cleaning is essential for both surface mount technology (SMT) and through-hole technology (THT) assembly processes. Cleaning helps remove accumulated surface contaminants from the product during various manufacturing stages, thereby reducing the risk of surface contamination and enhancing product reliability. When cleaning PCBA, it is crucial to ensure compatibility between the…

With the continuous improvement of manufacturing levels in China, steel mesh cleaning machines have been increasingly recognized by enterprises. Using automated cleaning equipment can significantly reduce costs for businesses. Therefore, most companies choose SMT steel mesh cleaning machines instead of manual cleaning. The emergence of steel mesh cleaning machines effectively addresses this issue. So, what…

Cleaning machines are mainly divided into hydraulic cleaning machines, high-pressure cleaning machines, ultrasonic cleaning machines, pneumatic cleaning machines, and spray cleaning machines. Steel mesh cleaning machines are widely used in electronic device manufacturers and SMT printing production plants. Large-scale production plants will purchase many targeted cleaning machines for screen printing screens. This is not only…
