Skived Fin Heat Sink

Skived fin heat sink is a unique machining process invented from Japan. Its design concept is an “ Integral structure” which optimizes the thermal conductivity to the maximum by the large surface area and allowing airflow ventilation.

To start with skived fin heat sink, selecting the alloy, either cooper or aluminum. Using the sharp and accurately controlled blade tool to shave the alloy block into thin slices in designated thickness and at the same time lift up each individual fin vertical to the base. Furthermore, CNC process can be applied to optimize the heat sink in neatness and precision, especially on top of the fin and base of heat sink or to remove scraps between gaps.

The advantages of skived fin heat sink process:

a. Seamless integral structure of base and fins

b. High density fin structure to enlarge the area of thermal dissipation

c. Low tooling cost

d. Can be made in both aluminum and copper

e. Perfect for limited space application

Illustration of skived fin heat sink process:

Angle setting is crucial for the cutting blade tool when it comes to skived fin heat sink. It’s often related to the thickness of the heat sink and the base. For higher fin, the angle of the blade tool will be smaller and for lower fin, the angle would be bigger. Here below is the specification we can achieve.

Specification of skived heat sink:

Material: aluminum unit:mm

Material: Copper unit:mm
