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. Skived heat sinks 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.

Skived fin heat sinks are commonly found in the following applications:

Computers and electronic components

Telecommunication equipment

Industrial equipment and components

Lighting lamps and household appliances industry

Automotive components
