How To Make Shiny Gold Bar?

How are traditional gold bars made? What a surprise!

The production of gold bars is still very new to most people, just like a mystery. So, how are they made? First, melt the recovered gold jewelry or gold mine to obtain small particles.

1. Pour the burnt gold liquid into the mold.

2. The gold in the mold gradually solidifies and becomes a solid.

3. After the gold is completely solidified, remove the gold nugget from the mold.

4. After taking out the gold, put it in a special place for cooling.

5. Finally, use the machine to engrave the number, place of origin, purity and other information on the gold bars in turn.

6. The final finished gold bar has a purity of 99.99%.

7. Workers who work here must be trained to not squint, just like a bank teller.

What Is Bonding Wire?

A bonding wire is a wire connecting two pieces of equipment, often for hazard prevention. To bond two drums, a bonding wire must be used, which is a copper wire with alligator clips.

Gold wire bonding offers an interconnection method within packages that is highly electrically conductive, nearly an order of magnitude greater than some solders. In addition, gold wires have a high oxidation tolerance compared to other wire materials and are softer than most, which is essential for sensitive surfaces.

Wire bonding is the process of creating electrical interconnections between semiconductors (or other integrated circuits) and silicon chips using bonding wires, which are fine wires made of materials such as gold and aluminium. The two most common processes are gold ball bonding and aluminium wedge bonding.
