Do these solders contain any precious metals?
Help Support Gold Refining Forum:
They can be about a 97/3, Au/Si. Or, whatever the eutectic is. They can be silver solder or just an epoxy.

GSP can you tell me what color the expoxy would be? I have been looking through some components and I have seen some solder on with what looks like it is barely gold colored, some that is definately silver colored. I did not see any white or clear that I think epoxy would look like.
I also found on large transisters with heat sinks that the sink portion is plated. Also some aromat relays with solid gold contacts.

Non-metallic. I don't remember if it was clear or not.
I'm not sure about other manufacturers but modern samsung memory does not have any pgm's or gold in their chips, the packaging itself in the older memory chips though do have gold plating and connecting wires to the pads are also fine gold.
