Abstract
Thermal interface materials and method of using the same in packaging are provided. In one aspect, a thermal interface material is provided that includes an indium preform that has a first surface and a second surface opposite to the first surface, an interior portion and a peripheral boundary. The indium preform has a channel extending from the peripheral boundary towards the interior portion. The channel enables flux to liberate during thermal cycling.
