I have the other piece(the male connector that goes inside it has a 90 deg elbow. With a rubber insulator where the wire goes in , inside is a single mylar insulated gold plated pin. The connector is light like aluminum and it looks like gold plate. Maybe its not but when scratched it is a silver color like alum. These are IR boards with 85-90 % gold coverage on them. There are 5 points on the board that have these connectors soldered to it. Like someone said maybe its not gold but I should be able to eat the metal up. So far no luck. I think I'm going to melt it and see what happens. they may be anodized titanium as these boards when working are 2000 each. So PM coverage is not a issue with these. I was lucky to get a couple hundred of them. I would send someone a sample to play with if anyone is interested. Also found gold all under the solder mask. Also the board when broken into pieces Has gold wires all through it. But any how back to the connector. Cannot get it to react with acid
What happens is it will melt.shel8483 said:I think I'm going to melt it and see what happens.
You can make that determination readily by simply removing a single pin and applying it to an aluminum oxide grinding wheel. Should yield a huge shower of white sparks. However, while I'm not about to suggest that titanium wouldn't be found in pins, it lacks many of the desirable properties that would make me think that's what they may be.they may be anodized titanium as these boards when working are 2000 each.
If all else fails, have you tried simply dissolving the gold with AR? Not a recommended practice, but if the pins happen to be titanium, that may work. Be certain that you have eliminated base metals before attempting AR, so it doesn't consume your acid and cement the values.But any how back to the connector. Cannot get it to react with acid
