The content of nickel sulfamate is as high as 180±3.75 g/L. The content of impurities in the product is very low, which plays an important role in reducing the accumulation of metal impurities in the plating bath. When the Cu2+ in the plating bath reaches 10-50 ppm, Zn2+ reaches 20 ppm, and Fe2+ reaches 30-50 ppm, the internal stress of the plated layer will be high and brittle. Nickel sulfamate is widely used in PCB as a backing layer for precious metals and base metals. For surfaces subject to heavy loads of wear and tear, such as switch contacts, contacts or plugs, nickel is used as a backing layer for gold, which greatly improves abrasion resistance. When nickel sulfamate is used as a barrier layer, nickel effectively prevents diffusion between copper and other metals. Nickel can be used as a resist layer containing ammonia-based etching agents, so the nickel/gold combination plating is often used as a resist layer, and it can be adapted to the requirements of hot-press soldering and brazing. The use of nickel sulfamate plating bath has a high deposition rate of the characteristics of the electroforming process for electroforming a variety of parts, typical electroforming products are: plastic or synthetic parts of the molding die, signs, electroforming precision up to microns below the record and laser discs and so on.
