In most cases, you can expect to get somewhere between 7-10 years on your board. If you don't take care of it correctly, you may get less. If you aren't hard on your motherboard and you don't expect much, it can last much, much longer. There are some motherboards that are over 30 years old that still work.

Allow the acid to react with the gold for 30 minutes. Add 120 milliliters of hydrochloric acid or muriatic acid for every ounce of gold in the container. Allow the solution to sit overnight until all of the acid fumes have been dispelled. Pour the acid into another larger container.

Computer-aided design (CAD) is the use of computers (or workstations) to aid in the creation, modification, analysis, or optimization of a design. This software is used to increase the productivity of the designer, improve the quality of design, improve communications through documentation, and to create a database for manufacturing. Designs made through CAD software are helpful in protecting ...

Computers and other electronic devices contain gold and other precious metals in their circuit boards. As consumers upgrade their electronic gadgets, the precious metals remain trapped in piles of waste. There's about 0.2 grams (0.007 ounces) of gold in a typical mobile phone handset. Recovery of this gold requires ...

The good news is that many older computer chips can be worth more than their weight in gold due to hungry vintage computer chip & CPU collectors. Most popular with chip collectors are the early Intel microprocessor chips such as the first microprocessor - the Intel 4004, and it's successors - the Intel 8008 & 8080, as well as early Intel Memory chips such as the first RAM - the Intel 3101 ...

Answer (1 of 4): Plain and simple? Old super computers. If you can get your hands on a high-end super computer from someone like Cray then you will find lots of high grade metals that are really worth recycling, especially lots of thick gold. Old supercomputer parts are almost worthless other t...

E Waste PCB Circuit Board Recycling Machine is used to recycle all kinds of Printed Circuit boards, such as the computer boards, cell phone boards, TV boards, copper-clad laminate, and other appliances, and the separation of leftover material of the mixed metal and nonmetal materials.

Using a 120-grit piece of sandpaper, sand the entire surface and edges of the furniture evenly. Then, wipe the surface with a soft, clean cloth to remove all dust and sand particles. While sanding your furniture, keep an eye out for any cracks or splinters. If your particleboard pieces are damaged, repair them before continuing.

The boards have some small flat packs so we also pull those. The CRT's go in the e recycle the plastics go back to the scrap source they have a buyer for those. WIth the whole world going crazy for flat screen LCD's there are a lot of old crt monitors coming available.

The red circle shows a finger mark smeared through the dust inside a desktop pc. But you won't know that your computer is only cooling down. You will think that it has died.

To remove gold from circuit boards, start by purchasing concentrated nitric acid from an industrial or chemical store. You'll also need a face mask, safety glasses, and industrial gloves to work with nitric acid, since it can harm your skin and eyes and cause nausea if it's inhaled.

Dust is a problem from the standpoint of blocking fan vents, or, if deep enough, actually insulating parts, causing overheating, but unless it contains substantial amounts of corrosive or conductive material (in which case you shouldn't be breathing it), it won't damage the electrical components (beyond any overheating damage).

Gold fingers are typically found on PCI cards, ISA cards, or on Memory sims/dimms/etc. They create the corrosion free connection between the computer and the expansion card. This process can also be used to recover gold from CPU such as Pentium Pro, or Cyrix or older 486 and lower generation chips.
