Hey together,
I have some gold fingers from old displays. After removing the connector cables they left some glue like residue on the plating (see pictures).
I tried removing it with screwdriver and a knife but it didn't come off.
My process would be to remove the the base metals with HCL/H2O2 but I'm not sure if the acid will go under that glue.
Does someone have any experience with that?
David
