The ultra-thick graphite film fired by ultra-thick PI has a qualitative leap in thermal conductivity, and its heat dissipation efficiency is much higher than current graphite film. After testing and verification of high-power heating modules,the thermal conductivity of ultra-thick graphite films in high-power heating scenarios far exceeds that of traditional multi-layer composite graphite films. After stacking into modules, some scenarios match the performance of heat pipes and VCs.
The thickness of the single layer is 50um~200um, which has super thermal conductivity, thermal conductivity ≥1300W/(m·K). It has good flexibility, consistency, and reworkability, and can be compounded with other film materials such as PET according to the application.
