Old mobile phone chip circuit boards can be used for the following:
< br >
Recycling precious metals: The old mobile phone chip circuit board contains gold, silver, copper, palladium and other precious metals, which can be extracted by recycling and refining.
< br >
Making handicrafts: old mobile phone chip circuit boards can be processed and transformed into artistic and practical handicrafts, such as mobile phone shells, watches, backpacks and so on.
< br >
Making teaching tools: Old mobile phone chip circuit boards can be used to make teaching tools, such as demonstrating circuit principles, electronic components, etc.
< br >
Making circuit test boards: Old mobile phone chip circuit boards can be used to make circuit test boards for students or electronics enthusiasts to perform circuit experiments and debugging.
< br >
Making electronic components: The electronic components in the circuit boards of old mobile phone chips can be inspected and repaired to make other electronic products, such as TV set-top boxes, routers, etc.

It should be noted that when dealing with the old mobile phone chip circuit board, it is necessary to ensure safety and environmental protection, and avoid environmental pollution and safety problems caused by random disposal or improper use.
1. Melt and regenerate
It will be refined and processed into raw materials for chips, and continue to make new mobile phone chips. That's what most mobile phone recycling companies do.
2. Re-label
If the mobile phone is recycled by some untrustworthy manufacturers, these chips are likely to be simply processed, re-printed with a new trademark and sold, and the mobile phone companies that buy these chips are usually some shanzhai manufacturers, or high imitation mobile phone manufacturers, these shanzhai chips can greatly reduce the cost of making mobile phones.
3. Refine gold
This use may not be expected by ordinary people, like some high-end models will be coated with gold on the metal contacts to increase the life and durability of the mobile phone, and some small workshops have seized this point, specializing in recycling the chip and circuit board after disassembly, and then extract gold from it.
4. Transform edge computing equipment
Using technical means to wake up the powerful computing power of the mobile phone chip, the \"computer\" equipped with a second-hand chip has become an edge computing device, and the computing power is amazing.
