Ink is a kind of new thermal heat dissipation material, uniform along the two directions of thermal conductivity, shielding the heat source and components at the same time to improve the performance of consumer electronics. With the acceleration of electronic products upgrading and miniature, high integration and high performance electronic equipment of the increasing thermal management needs. The new natural graphite solution, high cooling efficiency, light weight, small footprint, uniform along the two directions of thermal conductivity, eliminate the "hot spot" areas, shielding the heat source and components at the same time to improve the performance of consumer electronics.
