Long and Short Gold Finger PCB
Huayihai manufactures custom long and short gold finger PCBs for OEM manufacturers based on Gerber files, engineering drawings, and technical specifications.
This PCB uses a 6-layer reference construction with long and short (stepped) gold fingers, hard gold plating on the contact fingers, and ENIG immersion gold surface finish to support edge connector applications that require reliable contact performance and consistent manufacturing quality. Layer count, board thickness, base material, copper thickness, and solder mask are manufactured to customer specifications rather than fixed to a single standard design.
Custom Manufacturing Only
We manufacture gold finger PCBs according to customer Gerber files and technical specifications. We do not supply ready-made replacement circuit boards.
