Abstract
A fabrication method of a hexagonal boron nitride (h-BN)-based thermally-conductive composite film includes the following steps: S1. attaching an adhesive layer to an h-BN film carried on a carrier film, and separating the h-BN film from the carrier film to obtain a film in which an adhesive layer side is defined as a side A and an h-BN film side is defined as a side B; S2. attaching an adhesive layer to the side B of the film obtained in S1; S3. pasting a high-power graphite film to the side B of a film obtained in S2; S4. attaching an adhesive layer to the side B of a film obtained in S3; and S5. shaping a film obtained in S4 according to a required size. The present fabrication method is conducive to improving the production efficiency or yield rate of a thermally-conductive film product and the product quality.
