Well, many electronic applications and products need these boards. As there are a variety of fan boards, you need to use the right one for your product. Its early system prototypes can assist you in refining fan selection.
As there is the complexity of airflow, you need to choose the right fan by trial and error. We use the boards to bring about cool air replacing the hot air in the enclosure. Printed circuit board layouts and heat sinks transmit the heat from the hot electronic components.
Manufacturers use these boards as they are able to move the hot air by making a pressure differential. In short, we can say fan boards are an integral part of electronic devices. That is why the use of these boards is so important.
What Is The Manufacturing Process Of A Fan Board?
The manufacturing process of a fan board is likely to manufacture a printed circuit board. There are certain procedures to follow to get an accurate board. The manufacturing process of a fan board is as follows.
These boards move the air by producing a differential of pressure. By blocking the air, there can be pressure produced and no movement of air. But if you put the board out in the open, the fan will face no external pressure across the board and the airflow will get maximized.
These boards mainly operate somewhere in-between these extreme points. Manufacturers point many board datasheets by specifying the stable no flow pressure, CFM, or maximum free airflow in cubic feet/minute as well.
The electric system compound supplies the resistance of the airflow. This resistant system controls the airflow’s amount at significant pressures. The manufacturer needs to increase the airflow with increasing pressure for turbulent airflow.
You can easily adjust the DC fan speed by changing the DC voltage. When the airflow value changes with the fan speed, the pressure of the board changes as well. You can read the pressure with the help of a water manometer. These board pressure units are “in. H2O”, “in. wg” as such.
As a part of the prototype processing, the manufacturer fits a tube near to the electronic package along with the fan. Then run it to a water manometer in order to get the pressure measurement in the enclosure. The manufacturing company uses a DC fan to enable system air resistance measurement.
Manufacturing Process Of A Fan Board
This is the basic manufacturing process of a fan board. It can be changed regarding the application’s requirements. Advanced technology boards need a modified high technology manufacturing process.
What Is A Mechanical Fan Board?
A mechanical fan board is widely used in electrical devices. We can say it is the most used fan board in industries.
Mechanical boards supply automatic operation to support the mainboard. It plays a vital role to operate the main printed circuit board. The support system of a mainboard depends on a mechanical fan board.

Why Do You Use Fan Board In Desktop?
Fan boards are a major part of a desktop. A desktop can not operate perfectly without the assistance of the right fan. These boards help to run desktops smoothly.
We use fan boards on a desktop to operate every normal function smoothly and without hassle. The boards are able to give desktops the ability to install any functionality. It is placed inside of a desktop attached to the back or front case.
Fan board is an integral part of any desktop mounted inside of a computer case. Its main job is to provide active cooling for the computer. It draws cooler air from outside into the internal case of the computer.
Not only does it bring in cooler air, but the board also gets the warm air inside out. It passes the air beyond the heat sink to decrease the temperature of a component.
There are some standard sizes of fan boards for computers. These boards are controlled and powered with a 4 pin or 3 pins fan connector.
Fan Board In Desktop
Generally, we use axial fans on desktops. There are exceptions like sometimes we use centrifugal fans. Centrifugal fan board used in a desktop can be either blower or squirrel-cage.
How Do You Customize A Fan Board?
You may require to customize your fan board according to the requirement of your application or product. These boards are very much customizable as to your necessities. Manufacturing companies can customize the boards with proper knowledge and high technologies.

- Portable Fan
- Desktop Fan
- Mini Fan
- Multilayer Fan
- Rechargeable Fan
- Induction Cooker Fan
- Custom Fan
- 60w Fan
- 12v Fan
There are some more fan boards with individual purposes for application.
How Does Fan Board Work?
You can consider a fan board as a low-pressure air pump. It uses power brought from a motor. And then gives output as an airflow at a significant pressure given.
In a fan board, a propeller turns torque within the motor in order to raise the static pressure covering the board. This way the air particles’ kinetic energy increases.
The boards in the ventilation system application have three basic laws. These three basic laws give us the option to correlate the relationship between the major features of a fan board. The correlating features are static pressure, horsepower, fan airflow rate, and speed.
The heat sink is a cooling procedure to transfer dissolute heating from the device components into a cool temperature. This procedure serves the concept of conduction. In this conception, the heat transmits to a low thermal resistant area from a significant high thermal resistant area.
Well, all this cooling is necessary to ensure the reliability and longevity of the device. Heat is the main concern of fan boards. When the temperature of the device’s components exceeds its tolerance, the board takes countermeasures to solve the problem.
Fan boards ensure appropriate reduction of the heat from the components. It takes down the temperature to the device operating range to increase reliability. That is how a fan board basically works.
Watch the following video to learn in detail about how the fan board works.
What Is Noise In Fan Board?
Noise is a crucial fact in fan boards. You need to control the noise system in your fan. Noise level is a major datasheet parameter in fans.
Noise In Fan Board
Noise level is generally explained in dBA at a meter distance. As the dBA numbers get higher, the noise gets louder. It becomes really annoying when the noise is above 55 dBA.
The typical noise is 60 dBA in fan boards. Ears are very sensitive in the fan noise frequency range. As the speed reduces, the fan noise also decreases.
Air obstructions near the outlet and inlet make the fan noise worse. These obstructions can be like filters, heat sinks, tall components, filter assemblies, PC boards, cables, brackets, finger guards, debris, transformers, panels, walls, etc.
You can cut fan RPMs by half to reduce the noise by 15 dB. Airflow rate is proportional to fan RPMs. The system’s air resistance decreases the airflow and the fan’s RPMs.
Fan noise gets better in quality at lower RPMs. With airflow resistance, fans are generally quieter.
DC fan motor produces a pulse system load current. The peak of the current pulse is a lot high than the average of the current. You need to make sure there is no availability of sensitive circuitry in order to stop the current to cause a power supply ripple.
It is hard to filter when the ripple current’s frequency is low. For this reason, most systems apply another power supply for the fan boards.
How To Design With Multiple Fan Boards?
Sometimes you may need multiple fans for your device or application. Manufacturers use multiple fans to escalate airflow in those systems that are too hot. One fan exhausts cool air into the enclosure while the other fan blows warm air in a multiple fans series configuration.
Multiple Fan Boards
Multiple fan boards in series are effective for high resistance systems to airflow. In multiple fan series, the pressure gets nearly double. Still, the free airflow can not rise.
Manufacturers apply a parallel fan configuration in low air resistant fans. This parallel fan configuration works with double fans that blow in a similar direction. Here also the free airflow rate gets nearly doubled.
The static pressure can not increase in fans with low air resistant fans as two of the fans blow in the same direction. You can actually see the airflow’s relative increase in both the parallel and series combination of the multiple fans. If the fans finely match the system resistance, there is near about a 30 percent rise in the airflows.
That is why it is good to work with multiple fan boards in your product. You can personalize the boards according to the requirement of your application while designing multiple fan boards. Add your requirements when you design your multiple fan boards for the manufacturer.
How To Handle Fan Boards?
As fan boards are delicate and fragile, they need special care for handling. Micro fans that are printed circuit board mounted are very fragile. It requires special supervision in assembly.
PCB mounted micro fans can not be washed. The manufacturer needs to hand solder the wires. The boards also require special packaging and padding.
The manufacturer needs to provide special packaging and padding to ship the finished board assemblies. They need to handle the boards by their edges. You must not make a pile of the boards.
Fan boards are very precision balanced. If you mishandle the boards, the boards won’t work properly. Mishandling the boards can add a slight dysfunctionality to imbalance the noise level.
If the boards are not handled properly, their cooling performance and reliability decrease. While designing your fan board, add your handling requirements for the manufacturer to assembly.
How Do You Choose The Right Manufacturer For Fan Board?
You should choose the right manufacturer for your fan board. It is very important to get your fans as per your requirements. Check out if they use advanced technology and proper knowledge for manufacturing fan boards.
Look for if they have worked before with your industry fans. The manufacturing company should provide services for customization. Also, check the manufacturer’s experience in this field before you choose one.
