1. A heat sink for an element to be cooled comprising:

  • a base;

    a plurality of pins extending substantially perpendicular to the base, said pins being arranged in a predetermined pattern; and

    at least one projection integral with said base, extending from the side thereof adjacent the element to be cooled and having an area for the projection surface parallel to the side from which it extends and adapted to make thermal contact with the element to be cooled which is sufficient to provide good thermal transfer between the heat sink and the element while maintaining the area of contact to a fraction of the base area sufficiently small to assure that uneven thermal expansion between the heat sink and element does not cause damage to the element.
