Almost all driver chips, including cpus and graphics cards, contain trace amounts of gold (gold). But it's really a very small amount. In fact, mobile phones and other electronic products contain a variety of valuable materials, including 0.01% gold, 20% to 25% copper, 40% to 50% renewable plastic. Some electronic components contain a little bit of gold, which requires special extraction to get it.
The higher the gold content, the higher the gold content of the cutting-edge IC, the low-end civil grade IC has no gold, and the mobile phone IC contains gold.
IC this thing, only when the package from the core chip to the pin between the wire is gold wire, the core is silicon... Sand, pins of all kinds, anyway not gold, packaging material must not be gold, then, I think an IC gold content is related to the number of pins and the distance from the pin to the core
