A heat sink and an automated method of manufacturing the same are provided.　Corrugated fin components and base plates are stamped from coil- fed sheet in progressive dies. The corrugated component is staked to a primary base plate and the primary base plate is staked to a secondary base plate by plastically deforming conic posts into mushroomshaped heads, thereby mechanically joining components without loose fasteners or adhesives.　The manufacturing line may include multiple punch presses, staking stations, and positioning fixtures arranged about a rotary table or along a conveyor. Pick-and-place robots load the parts, and a PLC coordinates stamping, staking, inspection / sorting, and packaging. Vent apertures can be pierced in the corrugated component to promote omni-directional airflow.　The approach enables high fin density and increased surface area relative to die-cast or extruded designs, supporting reduced weight, lower material usage, and high-throughput production.
