What Are Skived Heat Sinks?
Skived Heat Sinks are a great way to cool powerful electronics. They are made by cutting thin fins from a solid metal block. This makes one smooth piece that moves heat away fast. The skiving process lets you make very thin fins that are close together. This gives more space for heat to leave. Because of this, you get better cooling than with many old designs.
Skiving Process Overview
A special tool cuts fins from a copper or aluminum block. You can see how this is different from other ways in the table below:
| Feature | Skived Heat Sink | Extruded Heat Sink |
|---|---|---|
| Manufacturing Process | Shaving thin slices from a solid block of material | Forcing material through a die |
| Fin Design | Very thin and closely spaced fins | Thicker fins |
| Thermal Performance | Enhanced heat dissipation due to increased surface area | Different thermal performance due to thicker fins |
Here are the steps to make a skived heat sink:
- Material Selection: Pick copper or aluminum for good heat movement.
- Preparation: Hold the metal block in the skiving machine.
- Slicing: Sharp blades cut thin layers to make the fins.
- Formation: Shape the fins to the right height and smooth the surface.
The skiving process makes sure the fins are the right size and smooth. This helps the heat sink fit well and work every time.
Single-Piece Construction
You get a heat sink made from one piece. The fins and base are not separate. This design removes extra barriers for heat to move. You get better heat transfer and a stronger product.

How Skived Heat Sinks Work
Thermal Management Principles
Heat Dissipation & Airflow
You need to move heat away from your device quickly. Skived Heat Sinks do this by creating many thin fins from a single block of metal. These fins give you a large surface area. More surface area means more heat can leave your device. Air flows between the fins and carries the heat away. This process keeps your device cool and working well.
You can see the main parts of heat movement in the table below:
| Thermal Resistance Component | Description |
|---|---|
| R_TIM | Heat moves from your device to the heat sink base. The material and thickness of the thermal interface matter here. |
| R-base-fin | Heat moves from the base to the fins. If the fins are part of the base, heat moves faster. |
| R-fin-air | Heat leaves the fins and goes into the air. Air speed helps this step. |
| R_air-rise | Air gets warmer as it passes through the heat sink. More airflow keeps things cooler. |
Skived Heat Sinks stand out because they have:
- A larger surface area for heat to escape.
- Better airflow between closely spaced fins.
- High fin density, which boosts cooling power.
Eliminating Thermal Resistance
You want heat to move with as little resistance as possible. Skived Heat Sinks use a single-piece design. There are no joints or glue between the base and fins. This means heat travels directly from your device, through the base, and out the fins. You do not lose energy at any connection points. This design gives you better performance than traditional heat sinks.
Performance in High-Power Devices
Handling High Heat Flux
High-power devices make a lot of heat in a small space. Skived Heat Sinks handle this by using thin fins and tight spacing. The manufacturing process slices layers from a metal block. This creates continuous paths for heat to travel. You can get fins as thin as 0.25 mm and as tall as 70 mm. These features help your device stay cool, even when it works hard.
Reliability Over Time
You need a heat sink that lasts. Skived Heat Sinks use a single piece of metal. There are no adhesives or bolts that can fail. This design resists stress from vibration and temperature changes. You get steady cooling for years. The seamless construction keeps your device safe and reliable, even in tough conditions.

Skived Heat Sinks vs. Other Solutions
Extruded vs. Skived
You might ask how extruded heat sinks are different from skived heat sinks. Extruded heat sinks are made by pushing hot metal through a shaped mold. This makes fins that are thick and all the same shape. Skived heat sinks are made by shaving thin fins from a solid block. This gives you more surface area for cooling.
Here is a table that shows the main differences:
| Feature | Skived Heat Sinks | Extruded Heat Sinks |
|---|---|---|
| Manufacturing Process | Precision machining from a solid block | Forcing heated metal through a shaped die |
| Thermal Performance | High thermal performance with intricate fins | Good thermal performance with standard fins |

Skived heat sinks let you pick more designs. They cool better than extruded heat sinks. You get a heat sink that fits your device and keeps it cool.
Bonded-Fin vs. Skived
Bonded-fin heat sinks use fins that are glued or soldered to a base. This can make thin fins, but heat has to move through extra layers. These joints can slow down cooling. Skived heat sinks use one solid piece of metal. Heat goes straight from the base to the fins. You get less resistance and better cooling.
If your device gets very hot, a single-piece design is a good choice. It works better and lasts longer.
Stamped & Die-Cast Comparison
Stamped heat sinks are made by pressing metal with strong force. Die-cast heat sinks are made by pouring melted metal into molds. These ways are good for making lots of heat sinks at once. But they can cost more to set up.
Here is a table that compares the cost implications:
| Heat Sink Type | Manufacturing Process Description | Cost Implications |
|---|---|---|
| Skived | Uses a Skive Machine to shave fins from a thick plate of aluminum or copper. | Low NRE; single-piece material reduces thermal resistance. |
| Die-Cast | Forces liquid aluminum into reusable steel molds under high pressure. | Good for complex designs in high volume; higher initial costs for mold creation. |
| Stamped Fin | Applies extreme pressure to form fins, which are then bonded. | High tooling costs; low cost per piece; suitable for thin fins with limited thermal performance. |

Design & Sourcing Guide
Key Design Parameters
When you make a custom skived heat sink, you need to think about some important things. These choices decide how well your heat sink works and how long it will last.
Material Selection
You have to pick the right material for your device. Copper moves heat very fast, about 400 W/m-K. Aluminum is lighter and costs less money. Both materials work well, but you should choose what your device needs.
| Material | Thermal Conductivity | Weight | Cost |
|---|---|---|---|
| Copper | ~400 W/m-K | Heavier | Higher |
| Aluminum | ~205 W/m-K | Lighter | Lower |
Think about how much cooling you need, how heavy it can be, and how much you want to spend before you pick.
Fin Geometry & Airflow
The shape and size of the fins matter a lot for cooling. Skived heat sinks let you use thin fins that are close together. You can make fins from 0.25 mm to 2 mm thick. Tall fins with high aspect ratios (up to 50) help cool small spaces. You also need to think about how air moves—natural or forced airflow changes how you design the fins.
| Design Parameter | Description |
|---|---|
| Fin Density | High-density fins increase surface area |
| Aspect Ratio | Up to 50 for compact, efficient cooling |
| Airflow | Match fin spacing to airflow type |
Base Thickness & Dimensions
The base spreads heat to all the fins. It needs to be thick enough to move heat well, but not too thick or heavy. Always check how much space you have in your device. Small designs are best for tight spots.
Tip: Write down your device’s power, top temperature, and space before you start your design.
Working with Manufacturers
Importance of Drawings
You should give clear drawings and details to your manufacturer. This helps them know what you need and make the right heat sink. Include these things:
