  • Publication number: 20150117035
    Abstract: Provided is a heat sink for a chip mounting substrate in which a heat dissipation material is embedded. The heat sink includes: an accommodation portion configured to accommodate a substrate whereon a chip is mounted or to be mounted, and support or fix the accommodated substrate; and a heat dissipation portion configured to insulate the accommodated substrate, and dissipate heat generated from the substrate or the chip mounted on the substrate to an outside through a heat dissipation material contained in the heat dissipation portion. Accordingly, since the heat sink for a chip mounting substrate in which a heat dissipation material is embedded is manufactured by injection molding, a manufacturing process can be simplified.
