Electroless plating is a special field in electronics plating and also called auto-catalytic plating, which is a chemical deposit process without additional power supplement.  The basal parts can be plated provided that they are dipped into the flowing plating bath.  Thereforethe electroless plating process is a plating process with excellent dispersive ability and very even plating layer.  With the above advantages, the electroless plating process, especially the electroless nickel plating, is widely adopted in electronics plating. Mid-phosphorus and high-phosphorus electroless nickel plating processes are mainly used in the nickel plating layer on magnetic disc.
