FAQ:

Q:What is Gold Finger PCB?

A:

Gold Fingers PCB is gold-plated terminal of a card-edge connector, usually, Fingers are fabriacate by flash gold (hard gold) and the gold thickness is requested to be from 3u“ to 50u“ because fingers are mainly used for pluging for many times.

When PCBs will be repeatedly installed and removed electroplated gold is used for edge-connector contacts or as they are more commonly known: Gold fingers

Gold fingers are edge connector contacts and are used to electroplate pads onto the board. The idea behind a gold finger is to help protect the Printed Circuit Board Prototypes from wear and tear. If applied correctly, with the right thickness, they are expected to last upwards of 1,000 cycles before there is any need of repair.
