Gold Recovery from IC BGA Chips Using Sulfuric Acid

 

Hello, welcome back! Today I'll introduce you to a method for extracting gold from IC BGA chips. First, we'll separate the IC chip from the motherboard. Next, we'll separate the black chip from the green PCB attached to the IC chip.

You'll see there are two parts:

there's the green PCB of the IC chip and the black package that encases it.

Place the black IC chip in a beaker. In this step, we'll separate the gold wire from the compound or black material. We use 98% sulfuric acid and boil it with the IC chip at 90 degrees Celsius. In my experiments, if the temperature exceeds 90 degrees Celsius, the gold will sometimes dissolve or disappear. We should use enough sulfuric acid to cover the IC chip 2-3 times its size. After the IC package or compound has completely dissolved, rinse it with water and gently rinse it off.

This step is quite dangerous, so be careful. The sulfuric acid reacts quite violently with water.

After washing, we'll see beautiful die chips and gold wires.

If you're willing to try, You can separate the gold wire and melt it down to obtain pure gold, or you can refine it to a higher purity with aqua regia, depending on your needs. You can find a video clip of this process on our channel.

For those interested in doing this at home, please consider the safety of yourself and others. Sulfuric acid is dangerous and you should have knowledge of chemicals and precautions before working. You should wear protective clothing and stay away from people and pets.

Thank you and see you in the next video.
