So I got these circuit boards that have a thick layer of gold over one side that is exposed and had a few rings exposed on the other...anyway when I went to cut it into pieces I realized the entire back side is covered with a solid gold plate and then covered with a layer of green plastic or some substance. Is there a process that will remove the layer of green stuff so that the acid in the AR can get to the Gold? I can't believe I didn't notice this...I would have thrown out a significant amount of gold. It doesn't have any other metal under it either. I peeled a good sized piece of gold off the other side of it and other than a film of some type of non-metal material, there was nothing under it...I have a few more of similar type coming soon...so I am anxious to see what I get. Any help will be greatly appreciated.
