A thermal dissipation structure and method are provided which include a heat sink having a surface configured to couple to a surface of an electronic component for facilitating removal of heat from the component. The heat sink surface and the electronic component surface comprise dissimilar materials with different coefficients of thermal expansion. The heat sink surface has a pattern of channels therein which define multiple heat sink substructures. Each heat sink substructure includes a portion of the heat sink surface. The portions of the heat sink surface are coplanar and provide a reduced distance to neutral point across the heat sink surface. When the portions of the heat sink surface are bonded to the electronic component surface, shear stress within the bond is reduced.
