With the development trend of ultra-thin, intelligent and multi-functional consumer electronics today, the increasing power and thinner products increasingly show the problem of how to disperse heat. Because of its outstanding characteristics in heat conduction, graphite sheet has attracted more and more attention, and is widely used in smart phones, ultra-thin PC and LED TV.

Application scope of heat conducting graphite sheet:

Thermal conductive graphite sheet provides better thermal conductivity by reducing the weight of the device. Graphite sheet cooling solution is a new application of thermal design.

Thermal conductive graphite sheet surface can be combined with metal, plastic, adhesive and other materials to meet more design functions and needs.

High thermal conductivity: graphite sheet can be attached to any plane and curved surface smoothly, and can be cut in any form according to customers' requirements.


In order to better adapt to the undulating surface of electronic devices and circuit modules, it is necessary to process the graphite sheet, the main processing methods are as follows:

1. Adhesive: For the purpose of better adhesion to IC and circuit boards, the adhesive is processed on the surface of the thermally conductive graphite sheet;

2. Back film: In some circuit designs that require insulation or heat insulation, in order to better optimize the function, perform back film treatment on the surface of the graphite sheet.

We can select suitable processing methods according to the actual needs of the products.
