Gold finger PCBs fail in the field more often because of DFM oversights than connector theory. This checklist walks you through 10 things to verify before sending Gerber files, from finger geometry, bevel and finish definitions to copper clearances, keep-outs, and panelization. Use it as a last pre-flight check to catch issues early and make your manufacturer’s DFM review much smoother.

Panelization and routing choices can make or break the yield and reliability of gold finger PCBs. This practical guide shows how to orient boards on the panel, place routing and break‑off tabs around the connector edge, use fiducials and keep‑outs, and route high‑speed and power signals into edge fingers without compromising manufacturability.

Hard gold and ENIG are the two most common finishes used on PCB gold fingers, but they behave very differently in real applications. This article explains how each finish is applied, compares wear resistance, solderability, corrosion performance and cost, and then walks through practical recommendations so you can decide whether your edge connectors really need hard gold or if ENIG is good enough.
