Copper & Aluminum Skived Fin Heat Sink SKV Series Skived Fin heat sinks can be an alternative to extruded heat sinks when looking for a fin density which cant 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 heat sinks are produced using a series of sharp knives that, as they pass over the material, curl up a small thickness 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 length as required by the final application. The final heat sink can be machined using normal fabrication techniques. Because of the thin fins, care must be taken in handling to prevent damage. It is suggested that a shroud be placed over the fins to help prevent damage. Wakefield- Vette SKV Series offers standard off the shelf solutions for customer applications in addition to custom solutions utilizing a plastic pin attachment. Features: Plastic push pin attachment for easy insertion Plastic pins ensure integrity of the PCB Board High fin densities in comparison to extrusion No interface between fins and base Minimal tooling cost for non-standards Improved thermal performance Thermal WKV Part Attachment Height Off Base Thermal Resistance Resistance Number Description Method Length Width (Height of Fin) Forced Air Flow Natural Material SKV38538514-CU COPPER HEATSINK 38.5X37.6X14MM Plastic Push Pin 1.480 (37.59mm) 1.516 (38.50mm) 0.551 (14.00mm) 2.60C/W 200 LFM 15.90C/W Copper SKV38538514-AL ALUMINUM HEATSINK 38.5X37.6X14MM Plastic Push Pin 1.480 (37.59mm) 1.516 (38.50mm) 0.551 (14.00mm) 2.70C/W 200 LFM 17.20C/W Aluminum SKV4545225-CU COPPER HEATSINK 45X44X22.5MM Plastic Push Pin 1.732 (44.00mm) 1.772 (45.00mm) 0.886 (22.50mm) 1.65C/W 200 LFM 8.00C/W Copper SKV4545225-AL ALUMINUM HEATSINK 45X44X22.5MM Plastic Push Pin 1.732 (44.00mm) 1.772 (45.00mm) 0.886 (22.50mm) 1.75C/W 200 LFM 8.70C/W Aluminum SKV505014-CU COPPER HEATSINK 50X50X14MM Plastic Push Pin 1.969 (50.00mm) 1.969 (50.00mm) 0.551 (14.00mm) 2.10C/W 200 LFM 8.90C/W Copper SKV505014-AL ALUMINUM HEATSINK 50X50X14MM Plastic Push Pin 1.969 (50.00mm) 1.969 (50.00mm) 0.551 (14.00mm) 2.20C/W 200 LFM 9.90C/W Aluminum SKV585811-CU COPPER HEATSINK 57.9X59X11MM Plastic Push Pin 2.323 (59.00mm) 2.280 (57.91mm) 0.433 (11.00mm) 1.90C/W 200 LFM 7.70C/W Copper SKV585811-AL ALUMINUM HEATSINK 57.9X59X11MM Plastic Push Pin 2.323 (59.00mm) 2.280 (57.91mm) 0.433 (11.00mm) 2.00C/W 200 LFM 8.40C/W Aluminum SKV606014-CU COPPER HEATSINK 60X60X14MM Plastic Push Pin 2.362 (60.00mm) 2.362 (60.00mm) 0.551 (14.00mm) 1.70C/W 200 LFM 7.00C/W Copper SKV606014-AL ALUMINUM HEATSINK 60X60X14MM Plastic Push Pin 2.362 (60.00mm) 2.362 (60.00mm) 0.551 (14.00mm) 1.80C/W 200 LFM 7.60C/W Aluminum SKV606021-CU COPPER HEATSINK 60X60X21MM Plastic Push Pin 2.362 (60.00mm) 2.362 (60.00mm) 0.866 (21.00mm) 0.80C/W 300 LFM 7.20C/W Copper SKV606021-AL ALUMINUM HEATSINK 60X60X21MM Plastic Push Pin 2.362 (60.00mm) 2.362 (60.00mm) 0.866 (21.00mm) 0.90C/W 200 LFM 7.90C/W Aluminum SKV707014-CU COPPER HEATSINK 70X70X14MM Plastic Push Pin 2.717 (69.00mm) 2.756 (70.00mm) 0.551 (14.00mm) 1.40C/W 200 LFM 5.60C/W Copper SKV707014 AL ALUMINUM HEATSINK 70X70X14MM Plastic Push Pin 2.717 (69.00mm) 2.756 (70.00mm) 0.551 (14.00mm) 1.50C/W 200 LFM 6.30C/W Aluminum SKV808012-CU COPPER HEATSINK 80X80X12MM Plastic Push Pin 3.150 (80.00mm) 3.150 (80.00mm) 0.472 (12.00mm) 1.20C/W 200 LFM 5.10C/W Copper SKV808012-AL ALUMINUM HEATSINK 80X80X12MM Plastic Push Pin 3.150 (80.00mm) 3.150 (80.00mm) 0.472 (12.00mm) 1.30C/W 200 LFM 5.70C/W Aluminum SKV909010-CU COPPER HEATSINK 90X90X10MM Plastic Push Pin 3.543 (90.00mm) 3.543 (90.00mm) 0.394 (10.00mm) 1.30C/W 200 LFM 4.50C/W Copper SKV909010-AL ALUMINUM HEATSINK 90X90X10MM Plastic Push Pin 3.543 (90.00mm) 3.543 (90.00mm) 0.394 (10.00mm) 1.40C/W 200 LFM 5.00C/W Aluminum www.wakefield-vette.comCopper & Aluminum Skived Fin Heat Sink SKV Series Attachment Height Off Base Thermal Resistance Thermal Resistance WKV Part Number Description Method Length Width (Height of Fin) Forced Air Flow Natural SKV38538514-CU COPPER HEATSINK 38.5X37.6X14MM Plastic Push Pin 1.480 (37.59mm) 1.516 (38.50mm) 0.551 (14.00mm) 2.60C/W 200 LFM 15.90C/W SKV38538514-AL ALUMINUM HEATSINK 38.5X37.6X14MM Plastic Push Pin 1.480 (37.59mm) 1.516 (38.50mm) 0.551 (14.00mm) 2.70C/W 200 LFM 17.20C/W WKV Part Attachment Height Off Base Thermal Resistance Thermal Resistance Number Description Method Length Width (Height of Fin) Forced Air Flow Natural Material SKV4545225-CU COPPER HEATSINK 45X44X22.5MM Plastic Push Pin 1.732 (44.00mm) 1.772 (45.00mm) 0.886 (22.50mm) 1.65C/W 200 LFM 8.00C/W Copper SKV4545225-AL ALUMINUM HEATSINK 45X44X22.5MM Plastic Push Pin 1.732 (44.00mm) 1.772 (45.00mm) 0.886 (22.50mm) 1.75C/W 200 LFM 8.70C/W Aluminum WKV Part Attachment Height Off Base Thermal Resistance Thermal Resistance Number Description Method Length Width (Height of Fin) Forced Air Flow Natural Material SKV505014-CU COPPER HEATSINK 50X50X14MM Plastic Push Pin 1.969 (50.00mm) 1.969 (50.00mm) 0.551 (14.00mm) 2.10C/W 200 LFM 8.90C/W Copper SKV505014-AL ALUMINUM HEATSINK 50X50X14MM Plastic Push Pin 1.969 (50.00mm) 1.969 (50.00mm) 0.551 (14.00mm) 2.20C/W 200 LFM 9.90C/W Aluminum
