Richardson RFPD (www.richardsonrfpd.com) announced the availability and full design support capabilities for a portfolio of skived fin heat sinks from Wakefield-Vette.
These standard copper and aluminum 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 0.5 mm (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. Skived 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
· Improved thermal performance
