Abstract
A heat sink includes multiple heat dissipating fins each with two opposite side walls. Multiple micro bosses are formed on a periphery of the heat dissipating fin. Each heat dissipating fin is securely connected to an adjacent heat dissipating fin via secure engagement between the side walls and a bottom face of the adjacent heat dissipating fin. Each micro boss is in the order between 10.sup.-6 to 10.sup.-9 mm so that laminar effect to decrease heat dissipating capability of the heat sink is avoided.
