1. Provide 6 kinds of thickness (0.3/0.5/0.8/1.0/1.2/1.5mm) for you to choose.
2. The thermal conductivity is up to 401 w/mk, very close to the silver thermal conductivity of 409 w/mk, much higher than ordinary copper pad (20-30 w/mk).
3. Exposed to air, the copper will inevitably oxidize and darken, but the cooling effect will not be affected. If you are still worried, you can polish the of this copper with fine sandpaper or toothpaste.
4. It can solve frequent laptop crashes and other problems caused by thermal conductivity.
5. Can be applied to the north and south bridge connection of the desktop computer, thermal conduction of the graphics card.
