Hi, here are some EPROMs (gold and not window) and some plastic IC’s I have, 15kg in total, are there some PM? May there be silver in the legs of the IC’s? What should I expect? Silver, gold and maybe palladium? The EPROMs are from the 80’s
That´s right. They are pretty heavy, with only very small area of gold braze. Also depends on a manufacturing date. Old stuff can be pretty rewarding, but it is rare today. Some old Eastern Germany made EPROMs had also gold plated legs. But that is more of a collector stuff, not for gold recovery.I have found EPROM's to have a low yield for gold and never found any that tested positive for PGM's. I not saying there isn't any out there that contain PMG's, but I've never found any.
Check the part numbers on eBay.... see sold/completed section for a reference on what has sold in the past. Some of those might have a collector value far above gold value.
