Principle, application and research prospect of electroless copper plating

Electroless copper plating is mainly applied to the metallization for PCB and electroplating on plastics, and copper electroless deposits have good ductibility, heat conductivility and electrical conductibility. Its application scope and development were introduced. This paper also emphasizes the necessity for pretreatment of electroless copper plating and some aspects that need attention including using grease that is easy to be cleaned as antirust agent and anodic electrolytic degreasing for low-carbon steel parts, and combined acidic decreasing and alkaline decreasing, etc. Some commonly used systems and their main components of electroless copper plating were introduced. The influences of additives were discussed. The research progress of electroless copper plating for nonmetal was reported. The research keystones of copper electroless plating were presented.
