Abstract

Embodiments include electronic packages and methods for forming electronic packages. One method includes providing a die and a thermal interface material on the die. A metal body is adapted to fit over the die. A wetting layer of a material comprising indium is formed on the metal body. The thermal interface material on the die is brought into contact with the wetting layer of material comprising indium. The thermal interface material is heated to form a bond between the thermal interface material and the wetting layer so that the thermal interface material is coupled to the metal body, and to form a bond between the thermal interface material and the die so that the thermal interface material is coupled to the die.
