Skived Fin Process
The skiving process enables high fin density and thin fin heat sink geometries for optimal thermal performance. By packing as much fin surface area into a given volume, skived fin heat sinks have greater heat transfer than other single piece construction heat sinks such as extruded aluminum heat sinks.
Product Introduction
Process Overview:
The skiving process enables high fin density and thin fin heat sink geometries for optimal thermal performance. By packing as much fin surface area into a given volume, skived fin heat sinks have greater heat transfer than other single piece construction heat sinks such as extruded aluminum heat sinks. Compared to extruded aluminum, skived fin heat sink fabrication does not rely on expensive tooling, providing greater design flexibility and faster prototyping. Instead, each fin is cut separately using the same tool which allows for lower tooling costs. This enables Sinda Thermal to fully customize skived fin components for your product, which also includes liquid cooling applications.

General Design Guidelines:
● Aluminum is better for higher aspect ratios
● Airflow lengths limited by cutter and the force required to fold up fins
● Most dimension variables have a tradeoff with other design variables due to the complexity of the manufacturing process. Contact us for assistance in optimizing your design for manufacturability and thermal performance.
● We’re always improving our machinery and processes so dimensional ranges are not necessarily hard limits. Contact us for our latest capabilities.
Skiving Process:
Skived heat sinks can be constructed of aluminum or copper allowing for full, one-piece copper solutions for high performance cooling. The mainly process are shown as below:
