发明名称 Method and apparatus for thermally coupling a heat dissipation device to a microelectronic device
摘要 Apparatus and methods are provided for thermally coupling a heat dissipation device to a microelectronic device. A reflowable thermal interface material is applied between the back side of a microelectronic die and a heat dissipation device. Heat and pressure is conducted through the heat dissipation device to the interface material and producing thereby liquefaction followed by solidification of the interface material, the solidification occurring progressively from the center to the peripheral edge. A thermal compression bonding apparatus is provided comprising a bonding head adapted to apply heat and pressure to the heat dissipation device whereby providing the desired thermal profile to effect solidification of the interface material from the center outward.
