Contact Finger Plating

  • Chapter

Abstract

Electrical connection to printed circuit boards can be made through various connectors, directly soldered connections, and contact fingers. One of the advantages of contact fingers is the ease with which a printed circuit may be installed and removed from a piece of electronic equipment; the circuit board can simply be pushed in and pulled out. The requirements for simplicity, ease of use, and reliability have placed several restrictions on the fabrication of the contact finger. The contact finger must be free of oxidation and corrosion, and remain so for the expected life of the equipment. It must also be wear resistant (hard). These needs are generally satisfied by using gold plated on top of nickel.
