GOLD FINGERS PCB - GOLD PLATED PCB BOARD

Goldfinger is gold plated on the edge of the board. We have an automatic Goldfinger production line that can provide you with professional and fast Goldfinger PCB production. Insert one end of the PCB board into the connector card slot, and use the plug pins of the connector as the outlet for external connection of the PCB board, so that the pad or copper skin contacts the corresponding pins of the corresponding position to achieve the purpose of conduction, and on the PCB board This pad or copper skin is immersed in gold or plated with nickel gold. Because it is in the shape of a finger, it is called a gold finger-printed circuit board.

Surface Treatment Method of Gold Fingers PCB

Gold Fingers PCB

1. Electroplated nickel gold: thickness up to 3-50u ", because of its superior conductivity, oxidation resistance and wear resistance, it is widely used in gold finger PCBs that require frequent insertion or removal or PCBs that require frequent mechanical friction Above, but because of the extremely high cost of gold plating, it is only used for local gold plating such as gold fingers. Jieduobang PCB calls it: selective electrical gold process, the color of the electrical gold process is silver-white, not as yellow as sinking gold. The disadvantage is that the weldability is slightly worse.

2. Immersion gold: conventional thickness 1u ", up to 3u" because of its superior conductivity, flatness, and solderability, it is widely used in high-precision PCB boards with buttons, IC, BGA, and other designs. For gold finger PCB that do not require high wear resistance, you can also choose the whole board immersion gold process. The cost of the immersion gold process is much lower than the cost of the electric gold process. The color of the immersion gold process is golden yellow.
