Circuit boards are common electrical components in our daily life. Generally speaking, they are divided into three categories according to the number of layers: single-sided boards, double-sided boards, and multi-layer boards. Pollutants will be generated in the manufacturing process of printed circuit boards, including pollutants such as dust and debris in the manufacturing process such as flux and adhesive residues. If the circuit board cannot effectively ensure a clean surface, resistance and leakage will cause the circuit board to fail, thereby affecting the service life of the product. In the process of using circuit board cleaning equipment, most circuit board cleaning equipment has the function of cleaning and drying, and the function of efficient cleaning is not yet complete, which is inconvenient to use. Because the surface of the circuit board is stained with plating liquid, the plating liquid needs to be washed off with cleaning liquid.
