All electronic devices contain gold

Uses of Gold in Electronics
The most necessary industrial use of gold is within the manufacture of physics. Solid state electronic devices use terribly low voltages and currents that square measure simply interrupted by corrosion or tarnish at the contact points. Gold is that the extremely economical conductor which will carry these little currents and stay freed from corrosion. Electronic elements created with gold square measure extremely reliable. Gold is employed in connectors, switch and relay contacts, soldered joints, connecting wires and association strips.

A small quantity of gold is employed in virtually each subtle device. This includes cell phones, calculators, personal digital assistants, world positioning system (GPS) units, and different little electronic devices. Most giant electronic appliances like tv sets conjointly contain gold.

One challenge with the utilization of gold in terribly little quantities in terribly little devices is loss of the metal from society. Nearly one billion cell phones square measure created every year, and most of them contain regarding fifty cents value of gold. Their average life is underneath 2 years, and really few square measure presently recycled. though the number of gold is tiny in every device, their huge numbers translate into tons of unrecycled gold.

Uses of Gold in Computers
Gold is employed in several places within the customary desktop or laptop computer. The fast associate degreed correct transmission of digital data through the pc and from one element to a different needs an economical and reliable conductor. Gold meets these needs higher than the other metal. The importance of top quality and reliable performance justifies the high price.

Edge connectors wont to mount chip and memory chips onto the motherboard and therefore the plug-and-socket connectors wont to attach cables all contain gold. The gold in these elements is usually electroplated onto different metals and alloyed with little amounts of nickel or Co to extend sturdiness.
