What is Skived heat sinks
Skived heat sinks are made by precision skiving of metal profiles, usually copper or aluminum, at specific angles and intervals to create high-density fins perpendicular to the base. This process results in thinner, denser fins, significantly increasing the surface area for improved heat dissipation.
These heat sinks are typically made from copper or aluminum, known for their excellent thermal conductivity—copper at 401 W/m·K and aluminum at 237 W/m·K. The skiving method minimizes thermal resistance when compared to conventional welding or pin-fin structures, improving heat dissipation. Furthermore, supplementary post-processing methods, such as incorporating copper tubes or utilizing surface treatments, can enhance cooling effectiveness even more.
Skived heat sinks are often considered a type of heat sink that can be customized to meet specific requirements, but they also come in standard versions suitable for various applications.Thanks to their superior thermal conductivity, compact design, and durability, skived heat sinks are ideal for a wide range of high-efficiency cooling applications. Custom heat sinks can be designed to fit unique configurations, ensuring optimal cooling performance in specialized devices. With increasing market demand, new designs such as wave-shaped and double-sided skived heat sinks are also available, offering even greater flexibility and cooling power.

4.Maximum Size Limits
Ecotherm can produce skived heat sinks with a maximum size of 3meter and a width of 900cm
| Material | Fin Thickness | Width | Length | Fin Heigh | Fin Pitch |
|---|---|---|---|---|---|
| Copper | 0.1-1mm | ≤900mm | ≤3000mm | ≤80mm | 0.16-12mm |
| Aluminum | 0.2-2mm | ≤900mm | ≤3000mm | ≤130mm | 0.2-12mm |
5.Fin Structure Design Guidelines
Thickness-Height Relationship
- Copper Fins: 0.1mm thick → 15mm high (straight) / 18mm (curved)
- Aluminum Fins: 0.2mm thick → 25mm high (straight) / 30mm (curved)
Edge Safety Distance
- Distance from the first and last fins to the substrate edge ≥ 50% of the fin spacing
- Tolerance of ±1 fin for 40 fins or more
Cross-Cutting
- Fins longer than 300mm require additional transverse cutting to suppress surface waviness
6.Cross-Cut Implementation
For extended fin configurations, the implementation of cross-cutting is advised to mitigate surface curvature deviations, suppress waviness formation, and enhance turbulent airflow dynamics.
7.Fin Removal for Component Clearance
To accommodate attachment hardware (e.g., fasteners or auxiliary components), machined features should be fabricated as square or rectangular geometries with radiused corner profiles. Clearance dimensions must correlate with the mechanical specifications of mating components (e.g., screw head diameter) to eliminate spatial interference risks. Final clearance parameters—including corner radii and dimensional tolerances—are determined through engineering analysis to guarantee manufacturability and milling precision. Post-machining, residual steps measuring approximately 0.2 mm will persist in fin-removal zones due to material subtraction during CNC operations.
