CPU Overview - Gold in the Chips

[Marcel]

Their are two methods here in the forum that will remove the plastic casing.
Look up pryolsis and wet ashing. Be warned of the dangers with the hot acid.

Thanks for the hint, but this is not for me and I suggest not for the occational refiner. Far too dangerous, if you dont have a professional lab and years of experience. Just not worth it.
If ericm is right you can either usw AP or AR. That´s the max for me and its ok.
But let me fumble a bit, I might find another way that is non-toxic.

Marcel,
Here is a link to Patnor's pryolysis method I mentioned. No acid here.

This one uses burning coal and a stainless pan. Complete incineration of all plastics.

Would caustic lye remove it like it does solder mask?

Can be. ...I think it is the same material the flat ribbon stuff is made of.
