If you could look closely inside your mobile phone or tablet device, you’d find small amounts of gold, silver, platinum and palladium — the four precious metals that are the “nuts and bolts” of modern electronics.
What metal is most used in electronics?
A variety of metals, plastics, raw materials and chemicals are used by the electronics industry. Some of the more common metals include copper, lithium, tin, silver, gold, nickel, and aluminum .
What electronics have precious metals?
Computer CPU’s (processors) have the most precious metal value by weight, followed by Memory (RAM) & Circuit Board Fingers / Connectors / Pins, then Circuit Boards (Motherboards), then cables / wires, with hard drives & whole computers being last.
Is there precious metals in circuit boards?
The most commonly used metal components on circuit boards are tin lead alloys, used in copper and solder to provide conductivity [144] . ... With regards to precious metals, circuit boards contain gold, silver, and platinum , as well as general-use metals, such as copper, aluminum, and iron [142].
How many precious metals are in a computer?
The average older desktop computer contains about $0.80 worth of gold – more if they have additional components like modems and memory or CPU chips installed. Laptops typically contain about that same $0.80 worth of gold.
How much gold is in a old computer?

What computer parts contain gold?
Motherboards and Circuit Boards
Motherboards – the biggest circuit boards inside both laptops and desktops – often contain the “mother lode” of gold in used computers. Their edges have gold contacts and connectors where wires slide on. You will also find thin layers of gold applied to motherboards’ surfaces.
How much is the gold in a cell phone worth?
There are 0.034 grams of gold in each cell phone, according to the U.S. Geological Survey. That’s the equivalent of 0.001 troy ounces, worth about $1.82 at today’s prices. There are also 16 grams of copper, worth about 12 cents, 0.35 grams of silver, worth 36 cents, and 0.00034 grams of platinum, valued at 2 cents.
Is there gold in old electronics?
It’s true there’s often silver, platinum, palladium and gold in our damaged or outmoded electronics , not to mention plastic, glass and other materials that have some scrap value. The primary reason is that precious metals conduct electricity much better than alloys.
Is gold or silver used more in electronics?
One of the reasons why is used in electronics is because of its electrical conductivity properties. Gold is highly conductive , meaning electricity can easily flow through it with minimal resistance. Copper, silver and aluminum are also conductive, but gold offers a superior level of electrical conductivity.
Is there gold in processor?
Some of the precious metals that are in these electronic devices include: Gold: Gold is used in printed circuit boards, cell phones, computer chips (CPU), connectors and fingers. Silver: SIlver is used in printed circuit boards, cell phones, computer chips, keyboard membranes and some capacitors.
Do all circuit boards have gold?
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.
Do all IC chips have gold in them?
Gold wire used in Integrated circuit packaging were typically 99.9% pure gold . All other components (caps, lids, pins & pads) were only gold-plated. Some manufactures have also used aluminum or copper wiring in the past in place of solid gold wiring to cut material costs.
Are old PCS worth anything?
These old computers can contain valuable metals such as gold, copper, and aluminum. ... Some reports suggest that an older laptop may contain $30 worth of gold , while newer units would include gold worth $15 to $25. Besides, it notes, there are still a lot of old laptops in storage that will eventually have to be recycled.
