Hello,
I'm looking for help determining the best path for refinement of the gold within multilayered RF boards. These boards are no expense spared microwave communication related boards, and used gold for all connections and throughout the board for the RF characteristics. There are 2 outer layers of gold traces and contacts, as well as 4 inner layers of traces. I have no experience with refinement but I am fortunate to have access to a large high temperature electric furnace, if that can be used for the process.
