Today more and more high-tech electronics are used such as the latest smartphones in your pocket, the thin, Ultra-thin laptops on your desk, and the ultra-high definition television on your wall. As electronics get faster, thinner and more powerful, the thermal challenges are more demanding than ever. The heat source is distributed in the charging module, six-cell aluminum battery, keyboard, PCB, PCU, LCD substrate board, side frame, and receiving signal terminals.
The thermal and electrical properties of graphite materials have a very significant heterogeneity. Through special preparation, the sheet structure can achieve thermal conductivity up to 1800W/MK in the XY plane, and the vertical thermal conductivity to 20-30W/MK on Z-axis, which is 4-6 times as much as common copper aluminum foil. For products with demanding design space, heat dissipation is the core issue.
Thin and light graphite sheet has the ability to effectively spread heat and is an ideal choice for cost effective thermal management.
