In the circuit board (PCB) manufacturing process, the filtration system is an important part of ensuring the stable operation of the production environment and equipment. The main function of the filtration system is to clean and purify air, water, chemical solutions, etc., to avoid adverse effects of pollutants on the production process, equipment performance, and the quality of the final product. There are mainly several kinds of filtration systems: air filtration system, water filtration system, chemical filtration system, oil smoke and exhaust gas filtration system, dust removal system, moisture filtration system, etc.
