Skived fin heat sinks support renewable energy trends

Availability and full design support capabilities for a portfolio of skived fin heat sinks from Wakefield-Vette has been announced by Richardson RFPD. These standard copper and aluminium skived fin heat sinks offer an alternative to extruded heat sinks for applications that require a thin fin density that cannot be achieved with extrusion technology.

Skived heat sinks typically have 0.5mm (0.020-inch) thick fins.

Skived heat sinks are produced using a series of sharp knives that pass over the copper or aluminum material, producing a thin curl of metal which is then bent vertically to form the fin.

The fins are produced from a bar of material which is approximately 16-feet in length and then cut to size as required by the final application. The final heat sink can be machined using normal fabrication techniques.

Wakefield-Vette’s SKV Series offers standard off-the-shelf solutions. Custom solutions are also available.

Key features of the SKV Series include plastic push pins for easy insertion and integrity of the PCB, no interface between fins and base, minimal tooling cost for non-standards and improved thermal performance.
