In many cases, the circuit boards have tiny amounts of metals such as gold, silver, copper and lead. These metals are used to improve conductivity. Although the gold is in small amounts, you can extract the metal from printed circuit board s.
Motherboards and printed circuit boards – The motherboard in particular is often the best potential source of gold in computers. The edges of most components on the board will have gold contacts and connectors where the wires slide in. You will often find thin layers of gold on the motherboard’s surface.

What parts of circuit boards contain gold
Random Access Memory (RAM) Chips – As part of this circuit board, these fancy little mines are installed to increase your computer’s RAM. They often contain a small, significant, but credible number of gold pins, as well as a thin layer of gold on their surface.
Why is a series resonant circuit called an acceptor circuit & parallel resonant circuit is called Rejecter circuit
Since the series resonant circuit operates only at the resonant frequency, this type of circuit is called an acceptor circuit because the impedance of the circuit at resonance is negligible and therefore it easily accepts the latter whose frequency is equal to the dog’s resonant frequency.
Why the series resonance circuit is called an acceptor circuit and the parallel resonance circuit is called Rejector circuit
Himanshu replied: A series resonant circuit is called an acceptor circuit because when the applied voltage consists of a large number of frequencies, some of the circuits must accept the maximum current only for the resonant frequency and reject all second frequencies.
Do all circuit boards have gold
Precious metals can be found in certain places on a computer, especially on the printed circuit board, processor (computer chip), hard drive, special capacitors, connectors, etc. Many electronic items contain a small amount of gold, particularly on the world map.
Do circuit boards contain mercury
Mercury is found in batteries, circuit boards, and switches. Flat screens, LCD screens also contain mercury.
How do I recover gold from circuit boards
Functional small-scale gold mining and processing can be done in the backyard with special equipment and widely available gas. Instructions. 1. Remove the gold forming joints and edges from the boards of the recycling program with pliers and a good back and forth motion to break off the gold fingers from the benefits of the board.
How much gold is in a circuit board
To equal one full ounce of 99.0.99% gold, a movement of 0.001 inch thick gold connecting wire can be 10,500 feet long. For 0.0007 inch thick gold bond wire, they will weigh approximately 21,000 ft. oz. per roll. a.

How much gold is in an average circuit board
How much does an average computer cost? Magann: The PC board is gold and weighs about a pound. If you have an avalanche of these boards, you must develop 5 troy ounces of gold.
What circuit boards have the most gold in them
Legacy Jumbo video players such as VCRs and Sony Betamax players. Older camcorders are better. Even the first digital cameras – again, the more the better. Old large desktop computers and ancillary equipment such as modems and scanners.
