ABSTRACT:
A heat sink includes a base, a set of fins mounted to the base and a plurality of fixing portions, wherein the fixing portions extend from a surface of the base and the set of fins are mounted on an opposite surface of the base. The heat sink is secured to a printed circuit board with at least one heat generating component through the fixing portion of the base. The heat sink is improved by forming one or more slots at lateral sides of the base such that one or more deformable portions can be defined on the base. Thus, the deformable length of the base is increased and the heat stress is relaxed.
