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.
