Electrolytic Nickel
Electrolytic nickel is commonly used as an undercoat prior to plating electrolytic gold. Nickel is a very corrosion resistent material and makes a good diffusion barrier between the base materials and the fold.
Kyocera has two types of electrolytic nickel:
- A matte finish, low stress sulfamate nickel. This nickel contains a few percent cobalt to enhance eutectic die attach reliability.
- A matte finish, low stress sulfate nickel which has excellent thickness uniformity (high throwing power). This nickel is available with or without cobalt.
For simple geometries, either type will yield good results. For complex geometries, the sulfate nickel will produce a more uniform thickness distribution. Sulfate and sulfamate nickel with cobalt solutions are available in both the automated and the manual plating line, while the cobalt-free solution is available only in the manual plating line.
Our line processes parts up to 6"x12" and weighing up to 20 pounds. Very small parts may be plated using barrel plating. Tie bars are required; however, it may be possible to connect through wires to the rack.
Thickness measurements are made using a Seiko XRF 7000 with NIST traceable standards. We are also capable of performing all MIL-STD-883 functional tests.
