[0002] Nickel plating is the process of plating a layer of nickel on metals or certain non-metals by electrolysis or chemical methods. Nickel plating is divided into electroplating nickel and chemical nickel plating. Electroplating nickel is in an electrolyte composed of nickel salt, conductive salt, pH buffer and wetting agent. The anode is made of metal nickel and the cathode is the plated object. Direct current is passed through the electrolyte to deposit a uniform and dense nickel coating on the cathode.

The patent discloses a technical solution to improve quality, which solves the problem that the tube core of the existing semiconductor device is gold-plated. When connecting the tube core of the semiconductor device, aluminum wires are often used for connection. The aluminum wires are directly bonded to the gold-plated parts and the aluminum wires are directly bonded to the surface of the gold-plated tube core. In theory, there will be Kirkendall voids in the bond between gold and aluminum. Kirkendall voids will affect the bonding strength and may cause debonding, seriously affecting the quality of the device.
