Stamping Heat Sink: The Ultimate Guide

Today’s guide explores all the vital information you need to know about stamping heat sink.

Whether you want to know about the fabrication process, uses, increasing efficiency, surface finish or mode of attaching stamped heat sinks – you will find all information right here.

So, keep reading to learn more.

1.  What Are Stamped Heat Sink?

These are types of heat sinks fabricated by subjecting metal to an intense pressures.

A heat sink is an element that helps to transfer heat away from a hot device.

It achieves this by increasing the device’s operating surface area and the amount of low-temperature fluid that flows through it.

One of the most important components in cooling electronic equipment is the heat sink.

A heat sink is required to transport heat away from the source and dissipate it through more optimized conduction.

Or convection for any heat source that cannot be efficiently cooled through its conduction cooling and requires more efficient cooling than a heat spreader.

Sheet metal is used to make stamped heat sinks.

2.  Stamping Heat Sink Process

The process of metal stamping the heat sink is not very complicated.

Stamped heat sinks are created by stamping a piece of metal through a press.

A tool is created in the shape of a heat sink, after which metal is transported through a stamping machine and the heat sinks are created by the stamp.

This is also a highly automated process, and as you might expect, once the heat sink design is finalized and the prototypes have been approved, the actual production is fairly easy.

Stamped heat sinks are commonly used in low-power applications due to their low performance.

They’re inexpensive, even less so than extruded heat sinks.

3.  Stamping Heat Sink Vs Cold Forging Heat Sinks

Cold forging produces round pin and elliptical pin heat sinks and is a highly precise procedure.

The forged heat sink has excellent microstructure integrity due to the high pressure and low temperature.

Stamping is commonly used to create tall heat sinks with heat pipes that go through the fins.

The pins on a forged heat sink are an intrinsic part of the base, they are simply squeezed out of the base, unlike stamped-fin.

Between the pins and the base, there is no air gap or thermal interface.

Without any additional resistance, heat can quickly dissipate from the base to the pins.

4.  Benefits Of Stamped Heat Sinks

Stamped heat sinks have certain attributes that make them advisable to use. They include;

  • Stamped heat sink offers a cheap one-time engineering fee, lowering prototype setup costs.
  • Stamped heat sinks provide a viable method for generating high-efficiency, high-aspect-ratio, low-weight heatsinks in tiny packages.
  • Stamped heat sinks offer catalog options for all package types.
  • For medium to large volume production, this is an excellent option.
  • Production is generally straightforward and low-cost because of its simplicity.
  • Stamps heat sinks are best for low-power applications.
  • Stamped heat sinks are fast and very easy to assemble.

5.  Extruded Heat Sink Vs Stamping Heat Sink

Extruded heat sinks are created by using a profile die to determine the fin density, pitch, and length, as well as the height and breadth of the base.

While stamped heat sinks are formed from sheet metal that has undergone a progressive punching process.

It adds details and characteristics to each stamp of metal that passes through the punching die.

extruded heat sink

Both extruded heat sink and stamping heat sink are affordable and save on cost.

Both of them are perfect for lower power applications but extruded heat sink can also work for medium power applications.

They both have a scalable high volume.

Extruded heat sinks allow for simple customizations.

Extruded heat sinks allow only for 1-piece construction for limited thermal resistance.

Stamping heat sinks has options for fast and easy assembly which is not the same for extruded heat sinks.

stamping heat sink

Stamping heat sink has catalog options for all package types.

Both extruded heat sinks and stamping heat sinks are not for high power applications.

They both have size limitations, with extruded heat sinks the width cannot be greater than 23 inches and the length cannot be greater than 47 inches.

With extruded heat sinks finishing can be a challenge, especially on larger sizes.

Stamping heat sink can only be used on one device and it is not for cooling multiple heat sources.

6.  Stamped Heat Sink Materials

When it comes to stamped heat sinks, aluminum and copper are the most common materials used due to their good properties.

Some materials can be used but are rarely used as they do not match up to the properties that copper and aluminum have.

Below are some of the properties of aluminum and copper that make them the best for stamped heat sinks.

Aluminum

Aluminum is the finest choice for stamping heat sinks because of its low cost and lightweight.

Furthermore, aluminum has excellent physical and thermal qualities.

Aluminum conducts heat very well and is the lightest metal that is non-reactive and not toxic.

It is very easy to work with aluminum and it is also cost-effective.

Aluminum may take on complex shapes for specialized cooling applications and is simple to extrude through complex dies.

Aluminum can also be black anodized, making it highly resistant to corrosion and providing better cooling via radiation, and all this is made possible using a low-cost chemical process.

Copper

Copper is twice as conductive as aluminum and has a higher thermal conductivity.

Also, copper is a metal with a high melting point.

It has double the corrosion resistance to that of aluminum.

Copper has antimicrobial resistance.

One of the biggest drawbacks of copper is that it is heavy and expensive.

7.  Uses Of Stamped Heat Sink

Stamped fin heat sinks are a versatile solution for a wide range of applications.

When creating stamped fin heat sinks, the combination of copper and aluminum is exceptionally responsive to the cooling requirements.

This is of improved performance circuits, such as overclocked computers.

Other applications for a stamped fin heat sink include forced convection currents, high-power chips (often over a hundred watts), and compact, hard-to-fit space constraints.

Finally, heat sinks are critical components of electronic systems that allow them to perform properly while regulating their temperatures under high loads.

8.  Machining Heat Sink Vs Stamping Heat Sink

The cost of a machining heat sink is quite high while that of a stamping heat sink is low.

With machining heat sinks, one can get the most complicated geometries and this allows for a lot of design ideas.

Machining heat sinks offer high thermal conductivity hence is ideal for high power applications but with stamping heat sinks, only low power applications are allowed.

There is a size limitation with machining heat sink but it allows for larger sizes compared to stamping heat sink.

9.  Essential Stamped Heat Sink Features

Stamped heat sinks have certain features that make them desirable.

The features include;

  1. Stamped heat sinks have a high thermal conductivity
  2. They have extreme fin thickness
  3. Stamped heat sinks are very cost-effective
  4. They have extreme efficiency which is one of the features that make them very popular. Because of this, they are the best choice for the smallest size of packaging.
  5. Stamped heat sinks have high density
  6. Stamped heat sinks have ingenious approaches to different thermal application designs.

10.  Stamped Fin Heat Sink Vs Skived Pin Heat Sink

Skiving is a method of fabricating from a single piece of metal by slicing layers from the top of the base.

To make fins, these layers are folded back to be perpendicular to the base, and the procedure is repeated at regular intervals.

Whereas, stamped heat sinks are formed from sheet metal that has undergone a progressive punching process.

Which adds details and characteristics to each stamp of metal that passes through the punching die.

skived pin heat sink

skived pin heat sink

Both stamped fin heat sink and skived pin heat sink are a great choice for low power applications and are not for high power applications.

They both have size limitations and cannot accommodate certain sizes.

Stamped fin heat sinks are cost-effective while skived pin heat sinks have lower tooling costs.

Stamped fin heat sinks are not for cooling multiple heat sources while skived pin heat sinks have a very high efficiency of cooling and better performance.

Stamped fin heat sinks have a scalable high volume while skived pin heat sinks are not as conducive to high volume.

Skived pin heat sinks have thin fins which make them a lot fragile compared to stamped fin heat sinks.

11.  Surface Finishes For Stamped Heat Sink

Surface finishes are protective coatings that protect the surface of the metal from different issues such as corrosion and help eliminate surface defects.

The following are some of the surface finishes you can use on stamped heat sink;

  1. Powder coating – a dry finishing procedure that protects the surface of a metal.
  2. Mill finish – used to describe materials that have no finish applied to them.
  3. Painted finish – this involves coating the surface of the material using paint.
  4. Polishing – involves rubbing or applying a chemical treatment to a surface making it smooth and shiny.
  5. Anodizing – changes the surface material making it durable, decorative, and able to resist corrosion.
  6. Electroplating – involves plating a metal onto the other using the hydrolysis method.
  7. Sandblasting – changes the material surface by either roughening the surface or making it smooth.
  8. PVDF – polyvinylidene fluoride allows for a wide range of matte-finish colors.
  9. Brushed finish – involves roughening the surface of the material to remove any form of corrosion.
  10. Silver plating – involves coating base metals with a layer of silver.

12.  Increasing Efficiency Of Stamped Heat Sink

To increase the efficiency of stamped heat sinks, there are certain features that one has to look into and make sure they are at their best to offer the best services.

Listed below are some of the ways efficiency of stamped heat sinks can be achieved;

Having Optimum Number Of Fins

Stamped heat sink fins take heat from an electrical gadget and distribute it into the cooling fluid around it.

As the distance from the heat sink’s base grows, the heat transmitted by a fin to the coolant medium decreases.

The total efficiency of the fins can be improved by using a material with better thermal conductivity and reducing the aspect ratio of the fins.

Material

Aluminum and copper are materials with strong thermal conductivity, and you can use them to create heat sinks.

Copper has qualities that make it a good heat sink material, but it is denser and more expensive than aluminum.

Its thermal conductivity, antimicrobial resistance, biofouling resistance, corrosion resistance, and heat absorption are all excellent.

Stamped Heat Sink Fins Location, Arrangement, Size, And Shape,

The placement of fins on a stamped heat sink has a significant effect on the flow of the coolant medium.

When the arrangement is optimized, the fluid flow resistance is reduced, letting more air pass through the heat sink.

The shape and style of its fins also influence its efficiency.

The heat transmission density can be increased by optimizing the shape and size of the fins.

The performance of various fin forms and configurations may be evaluated via modeling.

Thermal Resistance

The resistance between the heat sink and the fluid in motion, the die and the component casing, and the resistance between the casing and the heat sink, are all examples of heat flow resistance.

The total heat flow resistance between the die and the coolant fluid is known as thermal resistance.

Heat sink geometries and factors that permit maximum heat dispersion are determined through analyses of various heat sink designs.

Thermal resistance does not account for non-uniform heat distribution and is therefore inappropriate for modeling non-thermal equilibrium systems.

13. Stamped Heat Sink Attachment Method

Selecting an effective way of installing a stamped heat sink to an electrical gadget can improve its thermal performance.

The thermal and mechanical requirements of the thermal management solution should be considered during the selection process.

Standoff spacers, flat spring clips, epoxy, and thermal tape are all common heat sink attachment methods.

When attaching the stamped heat sink to an electronic gadget choose a method that will suit it the best.

Thermal Interface Material

Thermal contact resistance is increased by surface imperfections, roughness, and gaps, which inhibits the efficiency of a thermal solution.

By lowering the thermal contact area between an electronic component and its heat sink.

These imperfections increase heat flow resistance and thereby heat sink efficiency.

By increasing the interface pressure and minimizing the surface roughness, thermal resistance is lowered.

These methods of resistance reduction have limitations in most circumstances.

Thermal interface materials are utilized to overcome these limitations.

When choosing a thermal interface material for a certain thermal application, take into account the material’s electrical resistivity.

Also, contact pressure, and the size of the surface gaps to ensure its effectiveness.

14.  How To Reduce Cost Of Stamping Heat Sink

When purchasing a stamping heat sink, there are certain things a buyer has to do to ensure they get the best prices.

Stamping heat sinks have different prices and it depends on where you are buying them.

These are some of the ways you can use to get reduced prices for the stamping heat sinks;

1. Talk to various suppliers – talking to several suppliers helps you get various prices. Make sure you let the manufacturer you are buying from know you are talking to the others and they have cheaper prices.

2. Make sure to let them know you will buy a lot from them, by doing this they can reduce the price since they want to keep you as a customer.

3. Ensure you do your business with one manufacturer.

By doing this the manufacturer will have no problem giving you some discounts as they know you will be ordering a lot from them.

4. Be someone manufacturers want to do business with, this means you should be honest and make good deals. Manufacturers tend to have a good relationship with honest people and they end up giving them the best prices.

5. Ensure you don’t accept the first offer because most manufacturers are willing to change their prizes a bit depending on your bargaining power.

6. Ensure you don’t negotiate the price only but also try to ask for discounts on different things such as the shipping fee or the total amount of the goods bought.

7. Make sure you offer large deposits for your products, by doing so you may be able to get huge discounts.

15.  Die Casting Heat Sink Vs Stamping Heat Sink

One uses a single piece of metal to make die-cast heat sinks.

Die-cast heat sinks are generally made in large quantities for applications.

Which need to be light, have a high cosmetic surface quality, or have highly complex geometries.

On the other hand, you can form stamped heat sinks are from sheet metal.

That is, it should undergo a progressive punching process that adds details and characteristics to each stamp of metal that passes through the punching die.

Die casting heat sink

die casting heat sink

Die casting heat sinks are the best choice for higher power performance applications, whereby stamping heat sinks are best suited for lower power applications.

Die casting heat sinks have high tooling costs compared to stamping heat sinks, which are generally cost-effective.

Die casting heat sinks often take less time to manufacture than stamped heat sinks once they’ve been set up, which saves money when making heatsinks in large quantities.

Die casting heat sinks are suitable for complex geometries, which is not the case for stamping heat sinks.
