Connector Plating

 

Virtually all connector metal components are plated for both corrosion protection and functional requirements. Plating issues are among the leading causes for connector failure. The most common finishes are tin, tin alloys, and gold. In addition, nickel is often applied to the base metal as an underplate. Palladium, palladium alloys, silver, and other platings are used for special applications.

 

Low cost tin and tin alloys are used when possible. While tin/lead was the plating of choice for soldering applications, the removal of lead from the environment (RoHS) has made it necessary to develop new strategies. Gold is used when the contact requirements do not allow the use of tin or its alloys. Connector contacts are often selective or duplex plated, sometimes with gold on the contact area and a tin alloy on the solderable or crimp end.

 

APEX has expertise in all aspects of plating, from plating bath chemistries to the analysis of failed parts.
