Gold finger board
It is used to be inserted into the card slot and connected with the metal spring slice in it. While, the pad is arranged like fingers. Because there are high requirements on the wear resistance and conductivity of the pad surface with this design, a layer of gold will be plated on the surface of the pad, so, they are commonly called gold finger. Generally, the technology of adding the gold layer is immersion gold or plating gold. With the plating gold technology, the gold layer on the surface will be harder and more resistant to friction than with immersion gold. The gold finger board generally needs to be mechanically plugged and unplugged to the motherboard many times, so most gold fingers will be completed with plating gold. The price of the boards with plating gold technology will be higher, and the price of the gold finger board is related to the number of fingers.
