Features: Gold finger pcb with gold plating actually refers to thick gold, hard gold, also known as plug gold plating, does not refer to the whole plate gold plating, soft board. This kind of gold is characterized by relatively hard, can be plated very thick, resistant to plug
At present, many pcb cards have many gold fingers, which are used to insert into the card slot and contact and conduct the finger-like pads with the metal spring sheet in the card slot. Because such designs have higher requirements on the wear resistance and conductivity of the surface of the pad, a layer of nickel and a layer of gold will be plated on the surface of the pad, so they are commonly called gold fingers.
Through the contact and conduction between the golden finger and the spring sheet in the card slot, the interconnection between the external PCB and the main board is realized, and at the same time, it is convenient to disassemble and replace due to the difference in performance requirements of users. The most common goldfinger design appears on the graphics card and memory module inside the computer.
Gold finger circuit board using gold plating actually refers to thick gold, hard gold, also known as plug gold plating, does not refer to the whole plate gold plating, soft board. This kind of gold is characterized by relatively hard, thick plating and plugging resistance. Most of the time, the gold finger card board we hear refers to this type of board.
Hard gold has better wear resistance and can ensure that 20000 times of plugging and unplugging will not affect the quality. It must be more than 5U "thick gold. However, the hard gold processing process is relatively complex, the gold thickness requires high consumption of more gold salt, directly resulting in high costs.
