Gold Finger PCB

4-Layer Gold Finger PCB

Gold Finger PCB refers to those PCBs with finger-like pads applying plated gold surface finish, and they are usually used as edge-connectors.

Electroless gold gives excellent solderability, but the chemical deposition process means that it is too soft and too thin to withstand repeated abrasion. Electroplated gold is thicker and harder making it ideal for edge-connector contacts for PCBs which will be repeatedly plugged in and removed.

Gold Finger PCBs normally have to bevel the edge connectors to ensure easy insertion. Bevelling can be specified in the order details if there are any special instructions.

Application

The application of gold fingers to an edge connector provides an ideal surface finish for high-wear applications, such as an insertion connector. This is partly due to the fact that hardened gold provides a very planar surface that is resistant to wear from repeated insertions. For the manufacture of printed circuit boards, a bright hard gold with a mixture of nickel and/or cobalt is often used for card edge connector fingers plated over a nickel underlayment.
