Gold a key part of most circuit boards, due to how great of an electricity conductor it is, its malleability and its resistance to tarnish. The power supply has an iron core inside. Silver and palladium make up the solder and components of many circuit boards. Although less precious of a metal, steel makes up part of the outer casing Printed circuit boards inside electronic devices use a small amount of gold on key connections because of its conductivity and other properties. While many circuit boards are simply discarded, some companies--and even individuals--have turned to gold reclamation to strip circuit boards of their small quantities of gold Most circuit boards contain all sort of precious metals: Gold, Silver, Palladium and sometimes Platinum. All circuit boards contain base metals: Copper, Nickel, Aluminum, Zinc, Tin, Lead and Iron. As well, small amount of hazardous elements like Beryllium, Barium and others that has to be considered while processing scrap circuit boards I have scrap gold chains, gold ring, many old cell phones, including sim cards, some computer motherboards I like to process to extract the gold & silver.
