Fabricante e montagem da placa digital Gold - Serviço completo

Placa Gold Finger: (Gold Finger ou Edge Connector) Insira uma extremidade da PCB no slot da placa do conector e use o pino do conector como a conexão externa da placa PCB para fazer o contato de cobre ou almofada com o pino correspondente. Para atingir o objetivo de condução, e o ouro niquelado na almofada ou placa de cobre da placa PCB, porque é uma forma de dedo, é chamado de dedo de ouro.

Tipos e processos de Gold Finger Board:

In the large-scale use of PCI and optical modules, cable sockets, The golden finger has been divided into: long and short gold fingers, broken gold fingers, split gold fingers, During the processing of the gold finger plate, the gold-plated wire needs to be pulled.

The conventional gold finger processing process is relatively simple, and the length of the gold finger requires strict control of the gold finger lead, which requires secondary etching to complete. The difficulty of the gold finger is shorter than that of the long and short gold fingers. It requires three processes of the dry film. It takes 4 times for the lead to complete the production of the gold finger.

Often 90% of the enterprises cannot control the gold finger. Processing plug gold fingers and long and short gold fingers, broken gold fingers, 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 thick, gold plated called hard gold,

Why do gold fingers need gold plating?

Because it is used in graphics cards and plugs, boards often need to be plugged and unplugged. Gold plating is hardware. The number of plugging and unplugging can be up to 200,000 times. Immersion gold is software, and the number of plugging and unplugging is limited. Each plugging and inserting reduces the life of gold fingers.

O folheado a ouro é ouro duro, que é extraído no aspecto de tamponamento e inserção. A dureza do ouro no processo de inserção e inserção, o folheado a ouro tem desempenho superior na conexão e desconexão, e o desempenho da condutividade pode melhorar a eficiência da condução elétrica.
