I have some vintage hp circuit boards (1960-70's) that have either gold or gold plated traces on both sides. My goal is to figure out if these boards are worth the effort of refining or selling as gold scrap.
I don't have any experience with gold refining or chemicals (if there is a level below novice, that would be me). I'm mostly an electronics guy.
I think this forum is great and I have found ALOT of interesting stuff but I'm overwhelmed by the plethora of information. So to my questions...
1. I need to figure out what these traces are made out of gold or gold plate. I've scratched the surface and what's below is definetly NOT seem to be copper. Is there a kit or set of chemicals I could use to figure out what these traces are made of?
2. Once I determine what the traces are made out of, assuming they are plated, how do I measure the plating thickness? If they are solid gold traces, I assume I could just scrape them off and put them on a scale to get a rough idea of the amount pm I'm dealing with, is that reasonable?
3. If I decide to sell these boards as scrap, what is the best way to prep the boards and what is the best way to communicate to potential buyers what I have? I want to be as honest as straightforward as I can and get a fair price.
If someone could point this newbie in the right direction, I'd greatly appreciate it.
