Features of electroplating process and PCB electroplating equipment
Printed circuit boards can form industrialized and large-scale production, mainly due to the patented formula of electroless copper plating and colloidal palladium formula introduced by some well-known companies in the 1960s. The printed circuit board through holes use chemical copper plating to lay a good foundation for its industrialization, large-scale production and automated production. It has also become one of the basic processes for making printed circuit boards accepted by various manufacturers.

There are chemical copper plating processes in the above printed circuit board manufacturing process, and chemical copper plating is a very important link in the manufacturing process of printed circuit boards. The feature of electroless copper plating is that the solution contains a complexing agent or a chelating agent. The reducing agent is formaldehyde.
The complexing agent and formaldehyde in the electroless copper plating solution will bring harm to the environment and have great difficulties in wastewater treatment. In addition, the maintenance and management of electroless copper plating baths are also difficult. However, electroless copper plating is still a process that cannot be ignored in the manufacture of printed circuit boards.
Features of PCB printed circuit board automatic plating production line:
