Electrolytic Nickel Plating
QQN-290/MIL-P-27418
High temp/corrosive environment
Sulfamate, Watts or Electrolytic nickel is a good corrosive, ductile nickel. It is RoHS certifiable. The sulfamate nickel layer loses its ductility the brighter the finish due to organics being introduced to the bath. A dull nickel will be the most ductile. It is very useful as a an underplate. Electrlytic nickel is a good solderable surface. Plated per QQ-N-290 and MIL-P-27418
