Fabricant et assemblage de cartes à doigts en or - Service à guichet unique

Gold Finger Board: (Gold Finger ou Edge Connector) Insérez une extrémité du PCB dans la fente de la carte de connecteur et utilisez la broche du connecteur comme connexion externe de la carte PCB pour établir le contact du pad ou du cuivre avec la broche correspondante. Pour atteindre le but de la conduction, et de l'or nickelé sur le tampon ou la plaque de cuivre de la carte PCB, car il s'agit d'une forme de doigt, on l'appelle un doigt d'or.

Types et processus de panneau de doigt d'or:

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.

Le placage à l'or est de l'or dur, qui est extrait sous l'aspect du bouchage et de l'insertion. La dureté de l'or dans le processus d'insertion et d'insertion, le placage à l'or a des performances supérieures en termes de branchement et de débranchement, et les performances de conductivité peuvent améliorer l'efficacité de la conduction électrique.
