Patent ID: 7085135

Claim:
A thermal dissipation structure comprising: a heat sink having a first surface configured to couple to a second surface of an electronic component for facilitating removal of heat from the electronic component, wherein the first surface of the heat sink and the second surface of the electronic component comprise dissimilar materials with different coefficients of thermal expansion; and wherein the first surface of the heat sink has a pattern of open channels therein, the channels of the pattern of open channels extending into the heat sink a distance less than a thickness of the heat sink, and the pattern of open channels defining multiple heat sink substructures, each heat sink substructure including a portion of the first surface of the heat sink, the portions of the first surface of the heat sink substructures being coplanar, and providing a reduced distance to neutral point across the first surface of the heat sink so that when the portions of the first surface of the heat sink are bonded to the second surface of the electronic component shear stress within the bond is reduced.
