What is Skived Fin Heat Sinks

Skived Fin Heat Sinks offer the maximum heat dissipation in applications that have high airflow and small space. The thermal conductivity of copper (~400 W/m-K) is the highest among all the commercial metals, and the skiving technology allows the heat sinks to have very thin fins, high aspect ratio and high fin density. Because the fins are an integral part of the base, skived copper heat sinks provide the best possible thermal conductivity between the fins and the base. When optimized to specific applications, skived copper heat sinks offer outstanding performance over any other thermal solutions within the small space. In some applications, the skiving technology is also the most cost-effective and reliable method of producing heat sinks that meet high thermal demands.

Skived Fin Heat Sinks are manufactured by peeling fins from a bar of solid copper or aluminum, using a sharp and accurately controlled blade tool. The tool shaves a small thickness of the material, lifts it up and bends it vertically to form the fin. The final heat sink can be machined using normal fabrication techniques, such as CNC machining. Skived heat sinks require minimal tooling cost, which makes it a cost effective solution. Skived heat sinks can also be customized with embedded heat pipes to further improve performance.
