Skived Fin heat sinks can be an alternative to extruded heat sinks when looking for a fin density which can’t be achieved by extrusion technology and can be manufactured from either copper or aluminum and usually have 0.5 (0.020”) thick fins. Skived fins are achieved by a knife tool that literally shaves fins up from an extruded aluminum or copper base. This process of slicing and then standing the fins up one at a time can create an extremely high fin-to-gap aspect ratio. The top of the fins are then cut to maintain a uniform height.  This increased surface area drastically improves the thermal performance in forced airflow environments.
