The golden finger is composed of many golden yellow conductive contacts. It is called "golden finger" because its surface is gilded and the conductive contacts are arranged like fingers. The step gold finger PCB is actually coated with a layer of gold on the copper clad laminate by a special process, because the gold has strong oxidation resistance and strong conductivity.
The 8-layer gold finger PCB is actually coated with a layer of gold on the copper clad laminate by a special process, because the gold has strong oxidation resistance and strong conductivity.
Gold finger PCB In the extensive use of PCI cable socket gold fingers, gold fingers have been divided into: long and short gold fingers, broken gold fingers, split gold fingers, and gold finger boards. In the process of processing, gold-plated wires need to be pulled. Comparison of conventional gold finger processing processes Simple, long and short gold fingers, the need to strictly control the lead of the gold fingers, requires a second etching to complete.The following is about Gold finger Board related, I hope to help you better understand Gold finger Board.
In addition to the requirement for uniform thickness of the plating layer for drilling, backplane designers generally have different requirements for the uniformity of copper on the surface of the outer layer. Some designs etch few signal lines on the outer layer. The following is about Megtron6 step PCB related, I hope to help you better understand Megtron6 step PCB.
