Gold fingers are the exposed contact areas used when an FPC connects with a ZIF connector, board connector or mating socket. Good gold finger design helps the circuit insert smoothly, maintain stable contact and reduce avoidable quotation questions.

1

Why gold finger details matter

Small changes in contact length, pitch, stiffener thickness or coverlay opening can affect connector fit. If these details are unclear, the factory may need extra engineering review before confirming cost and lead time.

Key design points to confirm

  • Define the connector model, pitch and insertion direction.
  • Keep the coverlay opening clear around the contact area.
  • Confirm surface finish requirements such as ENIG or hard gold when needed.
  • Add stiffener thickness and material notes behind the contact area.

What to send for quotation

For a faster custom FPC quote, send Gerber files, production drawing, connector model, finished thickness, stiffener requirement and order quantity. Clear contact details help XTFPC review manufacturability and reply with a more accurate quotation.
