It is fairly easy to identify a Skived Heat sink as the heat sink 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.

The Skived fin, also known as skiving technology, simply takes an entire piece of aluminum or copper and use special skived machine to cut out fins with standard spacing and a certain thickness and height. Because of using high precision cutting technology, the integration of the forming, relative to other processing technology, the same volume of raw materials can be cut out more heat dissipation area, the heat transfer performance is more stable, in the same condition,the cooling performance is more than 1.5~2 times of the efficiency of traditional bonded fin or soldering heat sink, thus greatly improve heat dissipation efficiency and extend the service life of heating components.
