SKV Skived Fin Heat Sinks Wakefield-Vette SKV Skived Fin Heat Sinks are an alternative to extruded heat sinks considering the fin density, which extrusion technology cannot achieve. The SKV Skived heat sinks are manufactured using copper or aluminum with 0.5mm thick fins. These fins are produced from a bar of material, approximately 16ft in length, and then cut to length as required by the final application. The SKV series offers standard off-the-shelf solutions for customer applications and custom solutions utilizing a plastic pin attachment.
