Gold in Electronics
One of the most significant and noteworthy industrial use of gold is in the manufacture of electronics. Solid state electronic devices do not use a great amount of voltage and currents and which can be interrupted due to corrosion or tarnish at the contact points. Gold nonetheless is the very efficient conductor that is able to take the small currents and that will not become corroded. The electronic components that are made with gold are also very dependable. Gold is used in a lot of electronic components such as in connectors, switch and relay contacts, soldered joints, connection strips, connecting wires etc. almost all of the modern electronic devices we have these days have a little amount of gold in them. Some of the devices that one utilizes every day have gold in them such as in the case of cell phones, personal digital assistants, calculators and many other little electronic devices and obviously the bigger electronic appliances also have gold in them such as in the case of televisions etc. One of the biggest challenges with using of gold in little amounts is small devices is the loss of metal. Close to a billion cellular phones are made every year and these have around fifty cents of gold in each one. Most cell phones as we are all well aware of do not last more than two years, if even that and a great number of them are not recycled. Even though the quantity of gold that can be found in them is very small, the fact that so many cellular phones are sold every year mount up to a great amount of gold that is not recycled.
