ABSTRACT:
According to some embodiments, an outer metal is cladded to a core metal to create a cladded heat sink fin, the cladded heat sink fin is inserted in a groove of a heat sink base, and the outer metal is heated to a reflow temperature of the outer metal. Embodiments may alternatively include a heat sink base, an upper metal cladded to an upper surface of the heat sink base, the upper metal defining at least one groove, and a heat sink fin disposed in the groove and secured to the upper metal. Further to the foregoing, embodiments may include a lower metal cladded to a lower surface of the heat sink base, and a pedestal secured to the lower cladding.
