Among the large-scale use of PCI and optical modules and cable sockets, the gold fingers PCB has been divided into: long and short gold fingers, broken gold fingers, and split gold fingers.
Gold finger plates in the process of processing, need to pull gold-plated wire, conventional gold finger processing is relatively simple, the length of the gold finger PCB requires strict control of the gold finger lead and requires a second etching to complete.
Broken PCB gold fingerthan length The difficulty of the gold finger is increased, and the dry film is required to be processed three times. The lead does not need to be left for 4 times to complete the production of the gold finger .90% of companies are unable to process the control of the golden finger.
PCBSky processing plug gold fingers PCB and long and short gold fingers PCB, broken section Gold finger PCB, master the core manufacturing technology, single gold finger gold plating thickness up to 50U gold thick, industrial graphics card PCI can be processed to 50U gold thickness.
The most common PCB gold fingers design appears on the graphics card and memory stick inside the computer.
Why Choose Gold Fingers PCB?
★ A unique role of PCBA needs to be interconnected with the motherboard but needs to be replaced easily. Design the golden finger and slot connection, similar to the relationship between the power plug and the socket.
★ Because gold has good conductivity and inertness, it ensures the conductive effect without oxidation, and it also ensures sufficient conductivity after frequent insertion and removal of gold.
Gold Finger Definition and Role
Gold Finger (Gold Finger Connector or circuit board fingersConnector) inserts one end of the printed circuit board into the connector card slot, and uses the connector pin as the external connection of the printed circuit board, so that the pad or copper is in contact with the corresponding pin.
In order to achieve the purpose of conducting electricity, nickel or gold is plated on this mat or copper PCB board, because it is a finger shape, so it is called a gold finger. The reason why gold is chosen is because it has superior electrical conductivity and oxidation resistance. However, due to the extremely high cost of gold, it is only used for local gold plating.
