A pin fin heat sink for use in transferring heat away from a heat generating source is described which is manufactured by fusion or stud welding of fins to a base forming a continuous thermally conductive path for heat rejection. The method permits use of a broader range of thermally conductive materials, fin geometry and fin spacing than exists in current art. Having greater flexibility in fin design enables more efficient heat sinks with greater surface area and lower thermal resistance for any given volume. Relatively long thin pins are joined autogenously to a heat sink base with closely spaced adjacent surfaces by a capacitor discharge stud welding process without the need to apply significant force to the mating parts.
