At NICA, we offer both decorative and functional nickel plating. Bright nickel is deposited for decorative purpose and semi-bright nickel is for functional purpose. The high percentage of sulphur (>0.05%) of the bright nickel deposit will weaken its ductility and corrosion resistance. In order to solve this issue, a layer of sulfur-free nickel is underplated prior to the bright or satin nickel deposit. This sulfur-free nickel deposit is known as semi-bright nickel which is less electrochemical active than the bright nickel. This two-layer plating method is called duplex nickel with the semi-bright nickel layer is normally twice thicker than the bright or satin nickel layer. Semi-bright layer usually contains sulfur less than 0.005% generally deposited using watts bath without adding of brighteners or nickel sulfamate bath. Compared to the traditional bright nickel (using watts bath), semi-bright nickel using nickel sulfamate bath produces a deposit with highly compressive stress which makes it an excellent choice for applications subjected to high degree of compressive force and as an underplate for gold plating applications, including lead frames, interconnect pins and gold fingers.
