Step 3. There is some gold in most computer chips, especially older CPUs. Locate and remove any chips that can be removed, including CPU chips and chips that are soldered onto the boards. These can usually be removed by running a flat-blade screwdriver along the legs or by clipping the legs with cutting pliers.

In the first step, you must sort the gold into gold-plated parts: circuits which require cleaning, gold fingers, gold plated pins and so forth and so on. Before working with chemicals, don't forget to put on your safety gear. In the second step, you must put the clean circuit boards and the gold fingers inside the coffee pot.

Removing the Gold Gold can be removed from circuit boards in a variety of ways. It can be scraped off of the boards by hand, which is time consuming, but yields excellent results. The gold can also be removed via a process known as reverse electroplating, where a chemical solution and electricity are used to draw the gold off of the circuit board.
