Custom Heat Sink Manufacturer

Skived Fin Heat Sink Supplier

Skived fin heat sink can be an alternative to extruded heat sinks when looking for a fin density which can’t be achieved by extrusion technology. Skived heat sink can be manufactured from either copper or aluminum and usually have 0.5 (0.020”) thick fins.

Skived fin heat sink deliver maximum heat dissipation in applications with limited space and high levels of ventilation. They are a cost-effective solution when considering the low tooling cost and the optimized fin surface area.

PT heatsink is one of the best skived heat sink manufacturer in China, we have been successfully supplying small company and big enterprise with our custom extrusion heat sink design and manufacturing service over 20 years, thanks to extensive know-how and expertise.

Skived Heat Sink Manufacturing Process

Skived fin heat sink is achieved by a knife tool that literally shaves fins up from an extruded aluminum or copper base. This process of slicing and then standing the fins up one at a time can create an extremely high fin-to-gap aspect ratio. The top of the fins are then cut to maintain a uniform height.  This increased surface area drastically improves the thermal performance in forced airflow environments.

Skived Heat Sink Advantages:

Compared with other manufacturing methods, skived heat sink offer the following benefits:

  • High aspect ratio
  • Thin fin
  • Non or low tooling cost
  • Easy and inexpensive to prototype
  • Ideal thermal connectivity with the heat sink base
  • Unidirectional flow
  • Single piece construction
