Skiving involves shaving thin metal layers from a solid block to create intricate fins that increase surface area and improve heat dissipation. Our skived heatsinks offer superior performance and durability, making them ideal for various industries and applications. We pride ourselves on using only the best materials and techniques to create heatsinks that meet the highest standards of quality and reliability. Check our skived heatsinks if you need a reliable and efficient cooling solution.

WHAT IS A SKIVED HEATSINK?

A Skived Heatsink offers excellent thermal properties compared with other manufacturing methods as it offers a thin finned heatsink, with a dense population of uniformly shaped and distributed fins. As a Skived Heatsink is made from a single block of material such as copper or aluminum additional interface resistance that is common in other heatsink manufacturing processes such as stamped or folded fins that have a thermal resistance from the use of solder to attached the fins. This combination of high aspect ratio thin fins with no thermal resistance interface produces optimum cooling performance in high airflow applications.

HOW IS A SKIVED HEATSINK MANUFACTURED?

A Skived Heatsink is manufactured using a skiving machine that uses a blade to cut material in thin slices, and then push the skived fin up. For a heatsink application, the manufacture of ultra thin fins is possible, and we have produced fins as thin as .008”. The process allows high aspect ratios that provide greater surface area for maximum heat dissipation. We typically use this process for copper Skived heatsinks, however Aluminum Skiving is possible. As this is very easy to set up, typically there are minimal setup fees which allow for rapid prototyping of new designs. It is possible to machine additional features after the skiving process has been completed, but requires an experience to avoid stresses on the heatsink.

HOW TO IDENTIFY A SKIVED HEATSINK?

It is fairly easy to identify Skived Heatsink as the heatsink has a curve where the blade finishes its cut at the base of the heatsink as shown in the picture. In addition, the fins are not completely vertical, and curve slightly. This is more pronounced at the fins get taller. Typical width of the plate fin is 200 mm, but it is possible to manufacture up to 400 mm wide heatsinks by rotating the block of material and running a second pass with the curvature of the fins being in the opposite direction. As a Skived heatsink is manufactured from a long block of material, the only is no real limit to length of the heatsink is the length of the block. Different heights can be achieved by machining the block of material. Any excess material is recycled to reduce wastage. Typical Finishes for Aluminum skived heatsink are Anodization, or Nickel Plated. Typical finished for Copper Skived heatsinks are Anti-Oxidant, or Nickel Plated.

Skived Heat Sink Benefits/Features

1>Skived heatsink can be an alternative to extruded heat sink when looking for a fin density which can NOT be achieved by extrusion technology.
2>Skived heatsink fabrication does not need expensive tooling which provides greater design flexibility. Instead, each fin is cut separately using the same tool which allows for lower tooling costs.
3>Skiving heat sink can be made of copper and aluminum, enables solid copper solutions.The skiving process is a good thermal solution for high power cooling.
4>Skived heat sink leading the heat innovation high density ,high thermal performance, high aspect ratio, excellent performance.
5>Skived heat sink without interface joint between the fins and base, improved thermal performance than traditional heat sink.
6>Integrated manufacturing, no welding and mold opening;
7>The thickness and spacing of fin can be made thinner and denser;
8>The thermal conductivity is superior to the traditional extrusion and bonded fin process.
