Skived Fin Heat Sink

• Monolithic one-piece construction: Skived fin heat sinks are machined from a single block of aluminum (or copper), ensuring no joints between fins and base for superior thermal conductivity.
• Ultra-high fin density: Fins can be as thin as 0.2 mm, with minimal spacing-delivering significantly greater surface area and heat dissipation than traditional extruded designs.
• Highly efficient cooling: The integrated base-to-fin structure minimizes thermal resistance, enabling rapid heat transfer and enhanced cooling performance.
• Design flexibility without tooling cost: Skived manufacturing avoids expensive dies; fin height, thickness, and spacing are easily customized-ideal for prototyping and low-volume customization.
• Material versatility: Available in both aluminum and copper substrates-aluminum offers lightweight, cost-effective cooling; copper delivers superior thermal conductivity for high-power applications.
• Compact and lightweight: The thin fin profile enables compact designs with minimal added weight, suited to space-constrained or mobile electronic equipment.
• Robust mechanical integrity: With no fin-to-base interface, structural strength is enhanced, improving durability under thermal cycling or vibration.

• Base Material: High-conductivity aluminum or copper substrates
• Fin Thickness: Customizable from approximately 0.2 mm upward
• Fin Spacing: Adjustable fin gaps for optimal airflow and surface area
• Fin Height: Tailored fin heights based on cooling and clearance requirements
• Surface Treatment: Anodized, black-oxide, or custom finishes for durability and aesthetics
• Dimensions: Custom overall width, length, and height based on application
• Additional Machining: Machined mounting holes, threaded inserts, or PCB attachment features
