Skived fin heat sinks are manufactured by skiving (shaving) thin, continuous fins from a solid block of metal (usually aluminum or copper) using a precision knife. The process leaves the fins attached to the base as a single, monolithic piece.
- Benefits: Excellent Thermal Integrity: No interface resistance between fins and base. Very High Fin Density: Can create extremely thin (down to ~0.2mm) and tall fins for massive surface area in a small volume. Design Flexibility: Fins can be varied in height and shape along the length. Good for Liquid Cold Plates: The process can create integrated channels.
- Drawbacks: Higher cost than extrusion, typically limited to rectangular shapes. They are used in high-performance servers, telecom equipment, and aerospace applications.
