Interlaminar thermal joining member, interlaminar thermal joining method, interlayer thermal joining member manufacturing method

摘要

An interlayer heat-bonding member using graphite that exhibits excellent thermal resistance characteristics even when used between uneven members, and a method for manufacturing an interlayer heat-bonding member are realized. The heat-bonding member is composed of a flexible or fluid material (A) and a graphite film (B). The thickness of the graphite film is in the range of 100 nm to 15 μm and the density is in the range of 1.20 to 2.26 g / cm 3. The above problem is solved by setting the thermal conductivity in the film surface direction to 500 W / mK or more and the weight ratio (A / B) of (A) to (B) in the range of 0.08 to 25.
