The skived fin heat sink heat dissipation trait can be enhanced by this feature and the thermal conductivity can reach 100%.

  • A customized skived fin heat sink does not require costly tooling which provides greater flexibility in the design process.
  • High fin density- it can be made with several thin fins as possible and denser.

With an improvement of higher heat dissipation efficiency, an alternative solution and a breakthrough technology for bonded and extruded heat sink.

  • Skived fin heat sink can reach a height of 120 mm, which fully meets the production requirements of most heat sinks.
  • Size- when comparing skived heat sink with aluminum extrusion and other manufacturing heat sink processes, it is rarely limited to size.

This shows that you can make them have a wider profile.

You can dissipate heat within machines of high power using larger versions made by this feature.

  • Suitable for mass production- Skived fin heat sink has a high production capacity and the processing cost is easier to control.
  • Suitable airflow- It allows for a great forced solution for the flow of air.
  • Thermal interface- An additional thermal interface to the skived fin heat sink will allow you to suitably connect it to the heat source.

This will complete your thermal solution.

3.  What Is The Best Material For Skived Fin Heat Sink?

The best common material that is used are Aluminum alloys and copper.

When creating skived fin sink many manufacturers will prefer using aluminum material.  Aluminum is a good conductor of heat.

It’s a non-reactive metal and non-toxic.

Besides, Aluminum is affordable and easy to machine. It can assume complicated shapes to allow custom cooling tasks and is easy to extrude through complex dies.

Aluminum is high resistance to corrosion when it has been anodized.

Their temper will determine the values of these aluminum alloys.

Aluminum alloy 1050A is mechanically soft but has the highest thermal conductivity of value 229 W/m.K.

Aluminum alloy 6063 is used mostly in making skived fin heat sinks since its strength is relatively high and offers suitable machinability.

A fin thickness of value between 0.25 mm – 0.8 mm can be used in making the heat sink. Through this, you can be able to make fins that are lightweight and extremely thin.

Skived fin heat sink with a height of up to 150 mm can be made through the manufacturing method.

Besides, another material is copper. Due to its high thermal conductivity, copper is used in making skived fin hit sink since it allows heat to pass through it quickly.

Copper is also high resistance to corrosion, resistance to antimicrobial, absorption of heat, and biofouling resistance.

Copper has a high cooling efficiency. The thermal conductivity of copper is double that of aluminum material.

Copper is up to six times the cost of aluminum material and depending on the market also up to three times dense as aluminum.

4.  Where Can You Use Skived Fin Heat Sink?

In applications with limited space and high ventilation levels, skived fin heat sink delivers maximum heat dissipation.

Considering the low tooling cost and enhanced optimized fin surface finish, they are cost-effective.

The applications used are as follows:

  • Telecommunication equipment
  • Household appliances
  • Automotive components
  • Satellite equipment
  • Electronic components including LEDs and transistors
  • Industrial equipment and parts
  • Lighting lamps

5.  Which Are The Available Surface Finish For Skived Fin Heat Sink?

Polished Texture

Due to the polishing effect, this surface finish will provide the skived fin heat sink with a bright shine.

Sandblast Texture

The skived fin heat sink will have a matte and uniform finish given by this surface texture.

Brushed Texture

The patterns of the parallel lines can be easily seen by this surface finish. Through metal polishing the skived fin heat sink surface will receive a unidirectional satin finish.

Machined Finish Texture

The machine operating skived fin heat sink will determine the appearance of the texture.

Clear Chromate Finish

To coat the skived fin heat sink using electrochemical process, you will apply chromate coating. The skived heat sink will have a decorative surface finish.

This is after applying the chromate coating and this will help in maintaining its electrical conductivity.

Bead Blast Texture

It has a low gloss that makes it less reflective. The skived fin heat sink will also have a uniform texture through this surface finish.

Powder Coating

The dry powder used in this process is either a thermoplastic polymer or a thermoset polymer. Before curing it with heat you will use an electrostatic charge to apply dry powder.

The skived fin heat sink will have a surface finish formed on it by this powder that has the highest durability than regular paints.

Nickel Electroless Plating

Similar to that of clear chromate and anodizing electrochemical processes, Nickel electroless plating requires no electrical current.

An even metal layer will be formed on the skived fin heat sink by an electroless nickel plating

Anodized Finish

It’s an electrochemical process that creates a corrosion-resistance and durable surface finish.

This involves an electric current being connected through the medium and aluminum components dipped into an acid electrolyte bath.

The aluminum act as an anode while a cathode is mounted inside the anodizing tank.

This will allow oxygen ions to be released and combine with the aluminum surface and be anodized.

6.  Which Design Specifications Should You Consider In Skived Fin Heat Sink?

The following parameter indicates the limitation and recommended values of skived fin heat sink that are of low cost and high quality.

  • Maximum fin height of 100 mm of 4 inches
  • Maximum fin length is 500 mm or 20 inches
  • Maximum width: unlimited
  • Minimum fin spacing or gap of 0.1 mm or 0.004 inches

The slimmer design prevents the accumulation of heat into the heat sink. This makes it easier to remove heat, which boosts the life of electronic component and the speed.

  • The fin spacing or gap maximum of 8.0 mm or 0.31 inches
  • Recommended fin height is less than 50 or 2 inches
  • The material is copper(C11000) or aluminum (6063/1060)
  • A recommended thickness for copper fins is between 0.1 mm- 0.6 mm or 0.004 inches -0.024 inches
  • A recommended thickness for aluminum is between 0.2 mm- 1.2 mm or 0.008 inches-0.047 inches

7.  How Can You Increase The Efficiency Of Skived Fin Heat Sink?

The distance from the base of the skived fin heat sink rises as the fin heat transferred to the coolant medium reduces.

The fins’ overall efficiency increases when you preferably use a material that decreases the fins aspect ratio and has a higher thermal conductivity.

8.  Which Factor Affect The Cooling Efficiency Of Skived Fin Heat Sink?

Surface Color And Finish

The heat transfer from the skived fin heat sink occurs by conduction through the air, radiation, and convention of the surrounding air.

In the case where convection is low, radiative cooling can be of more significance.

Radiation governs the flow of heat between the environment and the skived fin heat sink.

Thermal Resistance

Thermal resistance does not factor non-uniform distribution of heat and is not fit for modeling systems that are not in thermal equilibrium.

Despite the fact that thermal resistance is an approximation in terms of value, it allows skived fin heat sink and semiconductor devices thermal characteristics in analysis and modeling.

Fin Arrangements, Size, Shape, And Location

Maximization of the heat transfer is through Optimizing the size and the shape of the fins.

Additionally, optimization of the configuration assists in the reduction of fluid flow resistance hence enabling more into the heat sink.

Through modeling, different fin configurations and shapes performance is evaluated.

The performance of skived fin heat sink is also determined by its fins design and shape.

Electronic Cooling Efficiency

The fins’ overall efficiency will improve when the material that has a high thermal conductivity and also decreasing aspect ratio of the fins is used.

The distance from the skived fin heat sink base raises as the heat transferred to the coolant medium by a fin reduces.


Skived fin heat sinks are designed using materials such as aluminum alloys and copper.

These materials have high thermal conductivity and are also resistant to corrosion.

The high thermal conductivity of these materials and high heat capacity helps in the absorption of more heat energy.

Conductive Thick Plate Between The Heat Sink And The Heat Source

A conductive thick plate being placed as a heat-transfer interface between the cooling fluid and the heat source can improve the performance of cooling.

In such arrangement, instead of the heat source being cooled with a cooling fluid in a direct contact it is cooled under the thick plate.

Through conducting the heat current in a manner likely to be optimal, the thick plate can enhance the heat transfer significantly.

Thermal Interface Material

It is a conductive material that increases the heat spreading and reduces the thermal resistance when applied between the heat source and heat sink.


They are normally utilized to extract heat to a skived heat sink from a variety of heat-generating bodies. Cavities impacted in a source of heat are the regions formed between adjacent fins standing for the essential promoters of condensation or nucleate boiling.

Attachment Methods

Selecting an appropriate method of attaching skived fin heat sink to a component or an electronic device will improve its thermal performance.

9.  Which Features Should You Look For In Skived Fin Heat Sink?

10.  How Do Skived Fin Heat Sink Work?

Skived fin heat sink work by absorbing heat from the parts. It consists of fins resembling that of a radiator.

As the parts warm-up, heat will transfer to the fins and a fan will release it. A fan is attached over a skived fin heat sink for circulation of air.

The fan draws the hot air away from the parts. Heat moves inside the skived fin heatsink and away from the source through natural conduction.

This will move it across the thermal gradient from a high temperature to a low-temperature environment.

The skived fin heat sink thermal conductivity will directly affect the working process.

11.  What Are The Components Of Skived Fin Heat Sink?

Some of the main components include:

  • Material
  • Thermal resistance
  • Cavities (inverted fins)
  • Microprocessor cooling
  • Fin arrangements
  • Surface color
  • Light-emitting diode lamps
  • A conductive thick plate between the source of heat and the heat sink.

12.  Which Types Of Skived Fin Heat Sinks Are There?

The following are the main types of the skived fin heat sink.

Active Skived Fin Heat Sink

For the achievement of suitable cooling within the parts, this type of skived fin heat sink contains added fans.

Blowing the hot air into the parts approaching the skived fin heat sink is the function of the fans.

Fans also blow out hot air from the parts towards the environment proving its efficiency as it boosts the heat sink thermal gradient.

active skived fin heat sink

Active skived fin heat sink

To achieve suitable heat transfer rates, active skived fin heat sink uses several cooling mechanisms such as forced liquids, fans, thermoelectric coolers, and blowers.

 Passive Skived Fin Heat Sink

When cooling parts, this type of skived fin heat sink will apply the convention methodology. Heat will transfer to the fins of the skived fin heat sink since it weighs less.

Through the application of heat spreaders, a passive skived fin heat sink achieves a natural convention and a high rate of heat dispersion.

Passive skived fin heat sink

There will be a continuous occurrence of convention process making airflow inside and around the skived fin heat sink.

Skived fin heat sink depends on pipes, heat spreaders, thermal interface material and sinks to sustain a suitable operating temperature level.

Hybrid Skived Fin Heat Sink

This type of skived fin heat sink uses a combination of active and passive skived fin heat sinks.

It’s less common and it normally operates with control systems to cool units.

This will depend on the temperature requirement. The system does not cool actively but cools passively when the heat sink is functioning at cool levels.

Hybrid skived fin heat sink

The active part will activate and assist in cooling the parts when the temperatures reach a higher level.

13.  How Does Skived Fin Heat Sink Compare To Bonded Heat Sink?

Skived fin heat sink fins are cut from single block metal usually copper while bonded heat sinks are produced by bonding individual fins into a base.

Skived fin heat sink allows a high fin density whereas bonded heat sinks are suitable for applications requiring large heat sink such as electric welder.

Skived fin heat sinks do not have interface joints like that found in bonded heat sinks which restricts the heat flow.

Skived fin heat sinks are from a single piece of metal which gives a lower thermal resistance.

On the other hand, bonded heat sinks both aluminum and copper are used to make fins thereby improving thermal performance.

Bonded heat sink

Bonded heat sink

The skived fin heat sink has a high weight and thick base which makes it directionally sensitive while Bonded heat sinks are expensive.

14.  Is Skived Fin Heat Sink Same As Pin Fin Heat Sink?

No, skived fin heat sink is a type of heat sink that gives a decreased thermal resistance since it is constructed from a single piece metal material.

Pin Fin heat sink
