Ic

[amt]

Hello

Can somebody tell me if those ic contain gold?

Thanks

Very little to none. What you get is what you see, probably some in the solder too. Keep the capacitors as they might contain ≤5% silver and ≤3% palladium.

Those are flip-chips. It depends on the legs or pins. If the pins are not gold plated, they are trash.

A small gold triangle on IC corner means it has gold

Unless they have gold plated pins, the tiny bit of gold you see on the surface cost more in acid than the return you get back in gold.

You could always cut off the visible gold, take the rest of the chip, then incinerate, crush, dissolve and test with stannous. Or pan it out after crushing "including the glass die"

The only possibility I could see of "hidden" gold in these, while ripping a couple apart with pliers/razor, would be in the hard plastic that is along the sides of the glass die itself. All that I see between the fiber layers and under the green mask is copper.

I believe there's a thread where someone actually tested these "incinerate etc".
