Disclosed is a graphite component comprising a metal substrate; and a graphite layer formed on the metal substrate. The metal substrate has one or more straight portions and one or more bent portions, which preferably forms a zigzag shape, each bent portion has a round shape, and a number of bent portions is two or greater. The graphite component may improve a heat radiation effect, such that lifespan characteristic and performance of an electronic device may be further improved.

Graphite component and manufacturing method thereof

Disclosed is a flexible copper clad laminate including a first copper foil layer, a composite layer, and a second copper foil layer. Preferably, the composite layer includes a polyimide layer and a plurality of thermoplastic polyimide layers as an outermost layer thereof being the thermoplastic polyimide layers. In particular, with respect to a total thickness of the composite layer, a total thickness of the plurality of thermoplastic polyimide layers is in a range of from about 15 to about 50%, and a total thickness of the polyimide layer is in a range of from about 50 to about 85%. Each thickness of the first copper foil layer and the second copper foil layer is in a range of from about 30 to about 80 &#x3bc;m, and the total thickness of the composite layer is in a range of from about 40 to about 60 &#x3bc;m.
