[0002] Printed circuit boards are intermediate products for manufacturing various types of terminal electronic products. Printed circuit boards are a platform that provides component connections and is used to carry the foundation for connecting parts. Printed circuit boards are structural components formed by insulating materials supplemented with conductor wiring. When the final product is made, integrated circuits, transistors, diodes, resistors, capacitors, connectors and other various electronic components will be installed on it, so that electronic signal connections and functional functions between various electronic components can be formed. The complex circuit copper wires used for connection on printed circuit boards are completed by the copper plating process. The purpose of copper plating is to metalize the resin and glass bundles of the non-conductive parts on the hole walls of the circuit board, and to deposit a layer of chemical copper on the non-conductive parts and glass bundles on the hole walls to facilitate subsequent electroplating of copper. However, the hole walls of printed circuit boards are located in different positions. When copper is deposited, the chemical reaction solution sometimes only soaks on the surface of the printed circuit board and cannot penetrate into the hole walls of the circuit board, resulting in poor copper plating effects, requiring additional processing by operators, and increasing the workload of staff.
