Gold Finger-PCBs
Gold Finger PCBs are circuit boards with gold-coated edges or connector areas (usually by ENIG process). These gold fingers serve as high-quality connectors for components like PCI-Express cards or network devices. The gold coating provides high corrosion resistance and enhances electrical conductivity, leading to a stable and reliable connection. This technology is commonly used in computer hardware, storage devices, and network devices where high signal quality and connection durability are essential.
