Ian You are describing a process that many in China refer to as "flash gold". The gold is electroplated and used as a solderability preservative and an etch resist. Several years age Urmi Ray presented a paper on this coating at IPC Expo. Best regards Lee J. L. Parker Ph. D.

It is lower-cost than ENIG and leaves the conductor side-walls exposed copper. Perhaps this is the process?

What exactly "Gilded" stands for? Just a common ENIG finition? Or something more precise? Thank you for your help.
