Problems solved by technology

Electroplating is an important process in the PCB manufacturing process. During the electroplating process, it is often encountered that the process and operation control are under normal conditions, but the plated products are not satisfactory. Defective products such as burrs and pits often occur. It involves a lot of chemical The use of liquid medicine will bring a lot of impurities and pollution particles in the process of PCB board going to and from each liquid medicine tank. If these impurities and pollution particles are not filtered to remove these impurities and pollution particles in the liquid medicine, it will seriously affect the quality and appearance of PCB products.

[0003] There are still some shortcomings in the traditional electroplating solution filter. Most of the existing filters on the market are manually operated. The structure and principle are simple but the operation is cumbersome and requires a lot of labor costs. After a period of use, the existing filter elements cannot meet the quality requirements. , It needs to be manually removed and cleaned or replaced with a new filter element, which increases labor costs. When cleaning and replacing the filter element, the expensive electroplating solution is also drained with the waste liquid, wasting the electroplating solution and water source, and also produces waste water. Moreover, the installation of the follow-up filter element depends on the worker's technology and work responsibility, which may easily cause the filter element to not be sealed, the bath liquid cannot be effectively filtered, and the filtering effect is difficult to guarantee
