d) Chromate finish – It entails converting metal surfaces to ensure excellent corrosion resistance.

12.  How Active Custom Heat Sink Compare With Passive Custom Heat Sink

Custom heat sinks are classified into two main categories based on the working principle and the overall design construction.

Ordinarily, active custom heat sink features a mechanical element designed to facilitate the cooling process.

As such, the fans and blowers in this custom heat sink design perform effectively in the general cooling process.

However, the active custom heat sink is seemingly more expensive than passive custom heat sink.

Passive custom heat sinks, on the other hand, do not come with any mechanical element.

Thus, the functionality module of this heat sink works by cooling the device or appliance through a convention process.

Therefore, it implies that heat dissipates into the air as air flows across this particular custom heat sink design.

You will, thus, notice that passive custom heat sink seemingly exhibits more reliability since you hardly find them with any moving component.

13.  Heat Transfer Principle In Custom Heat Sink

Custom heat sink works like most designs, only that it is customized to meet the conditions or requirements of a specific application.

The process begins when heat is produced at the system device, which is regarded as the source. Amount of heat produced should be reasonable enough to enable the component to eliminate heat to function.

Heat transfer the sets in by moving from the source towards the custom heat sink. At this point, thermal conductivity of the custom heat sink determines the heat transfer rate.

The next phase is heat distribution, which merely involves heat movement to the custom heat sink, either actively or passively.

It normally happens as heat moves down temperature difference, particularly from high to low temperature surroundings.

Thus, the thermal profile of custom heat sink could be uneven, making it quite hot at the source and cold on the ends.

Finally, heat dissipates through fluid moving across custom heat sink and applies thermal convection and diffusion to reduce heat.

For effective heat dissipation, there should be a temperature difference between heat sink and environment.

14.  Factors Influencing Custom Heat Sink Performance

Several factors determine the actual performance of custom heat sink, and the main ones include the following;

Thermal resistance

Ordinarily, the design of this component allows heat to flow between ambient air and semi-conductor die.

Thus, resistance exists from the device’s casing to heat sink and from the heat sink to ambient air.


The overall size of custom heat sink determines its general efficiency.

In essence, smaller heat sinks are less efficient than bigger ones.


Copper and aluminum are the base materials for manufacturing highly effective custom heat sinks.

But they have different alloys possessing a wide range of properties that influence the overall performance of this component.

Spreading resistance

Heat never spread uniformly through a typical custom heat sink base.

However, spreading resistance causes an incredible temperature gradient between device edges and heat sink edges.

15.  How To Attach Custom Heat Sinks To Boards

Custom heat sinks used in various applications tend to be somewhat highly versatile.

Some common methods you can use to attach them include the following;

Using Thermal Tape

It entails using adhesive tape designed from different acrylic substances.

This tape is usually pressure-sensitive making it easy to adhere to the surface.

However, when using thermal tape, always ensure chip and custom heat sink surface are clean to allow the tape to bond correctly.

Using Thermal Epoxy

It involves using a compound with either single or dual part but combined with adhesives and fillers containing thermal conductive features.

This method guarantees incredible mechanical adhesion and affordability.
