Is there gold in led light circuit board?

Yes, but very few. Usually, the contact plate of the connector of the circuit board will be gold-plated with anti-oxidation, and the contact pin of the interface device of the display will also be gold-plated. Some interfaces will be gold-plated, such as sata interfaces, but gold-plated anti-oxidation. Contains trace amounts of gold and silver, present at key contacts and welds.

The Goldfinger CPU and all the interfaces on the motherboard are not available, it's all copper if you want to do it after.
