Gold in electronics
The amount of gold used in the industry is about 10%, and its most important use is in the electronics industry. Corrosion resistance, electrical conductivity, malleability and non-toxicity are the advantages of using gold in industry.
Gold is used in this industry to make electrical connectors in computers and other electrical devices such as communication equipment, spacecraft, and jet engines. For example, about 50 mg of gold is used in making a normal mobile phone.
Features such as good conductivity and resistance to oxidation and corrosion in non-chlorine environments have made this element widely used to cover electrical connection equipment. It is used in the construction of electronic cable connections such as audio, video and universal serial bus (USB) cables. Very fine gold wires are used in the connection of semiconductor parts using the wire bonding process. Because of their high conductivity, gold, silver and copper are mainly used for electrical wiring and transmission of electricity, and the advantage of gold over silver and copper is corrosion resistance. .
