Aln PCB or aluminum nitride PCBs are PCBs containing conductive materials. This ceramic PCB has high thermal conductivity standing at around 170w/MK. This combines with its low thermal expansion coefficient as well as its strong dielectric.

All these properties make the Aln PCB or Aluminum nitride PCB have high performing solutions for circuits delivered for the high temperature and high current coefficient. Furthermore, aluminum nitride (Aln) can be seen in different colors, thicknesses, shapes, and sizes. These are very important in several applications. You can find this in automotive companies and radio frequency companies, power companies, LED converters, etc.

What are the Properties of Aluminum Nitride PCB (Aln PCB)?

Aln PCB has properties that make it a reliable choice for several applications. You can group them as physical, chemical, as well as environmental properties. Some factors can be considered. These factors are thermal expansion, density, dielectric constant, comprehensive strength, melting point, tensile strength, bulk modulus, breakdown potential, and minimum as well as maximum service temperature.

Thermal Expansion

Aln PCB has a thermal expansion with its maximum and minimum value standing at around 5.61 and 4.3 SI units respectively.

Melting Point

Aln PCB has a melting point of more than 2000 degrees Celsius

Thermal Conductivity

Aln PCB is well-known due to its great thermal conductivity having a value of 170w/Mk. With this value, it makes it a very good option for several applications.

Electrical Insulation

Aln PCB provides a reliable electrical resistance. Due to this, it is a reliable electrical insulator.

Density

Aln PCB comes with an average value of density of about 3.6g for every centimeter cube. Furthermore, in different environmental properties, the focus has to be on aluminum nitride’s response to moisture, temperature, corrosion, UV radiation, etc.

UV Radiation

Aln PCB helps in resisting UV radiation due to its oxide layer formation

It resists corrosion

Protective surface finishes and coating which are applied onto it protects and surrounds the Aln PCB. This helps to protect it from corrosive effects, which appears from its environment.

It resists extreme temperatures

Aln PCB offers strong resistance to extreme temperatures which could reach 1370 degrees Celsius. Temperatures that are higher can result in a material passing through bulk oxidation. Furthermore, Aluminum nitride (Aln) is usually stable in carbondioxide and hydrogen atmospheres.

Why Should You Choose Aluminum Nitride PCB (Aln PCB)

If thermal conductivity is the driver, then the best option to use is Aluminum. It includes a value of 170w/mK for the thermal conductivity. With this value, systems that are very demanding will find this PCB useful.

In addition, it includes properties such as small package sizes, strong dielectric, and high temperatures for operation. This occurs due to the hermetic packages, integration, low thermal expansion coefficient, etc.

Having these properties in place, it allows the use of Aln PCB in several fields and applications. These include high-current switches, high-power LEDs, lasers, etc. Moreover, Aln PCB manufacturing is achieved using high-grade materials which are both tough and resilient. This ensures that the product is very durable. This durability will help you to save any costs related to repair and maintenance.

Manufacturing the Aln PCB (Aluminum Nitride PCB)

Note that Aln (Aluminum nitride) is known as the synthetic or inorganic ceramic component which is manufactured majorly from aluminum and nitrogen steel. The manufacturing process of aluminum nitride involves two major processes.

• Carbothermal reduction and nitridation
• Direct nitridation

When manufacturing the Aln PCB (aluminum nitride PCB) the most preferred method is direct nitridation. Explaining further, Carbothermal nitridation as well as reduction serves as an alternative for direct nitridation. Moreover, for most cases, this is useful for alumina nitride production.

This method offers a great benefit because it is environmentally friendly. Therefore, it won’t produce harmful by-products, as well as greenhouse gasses. It is also energy efficient. However, the process of manufacturing has its own disadvantages. The process of milling might bring in some impurities. Furthermore, breaking the aluminum nitride formed. Here is why multiple steps may be needed for reduction in size so as to attain the particle’s desired size.

Aluminum Nitride PCB (Aln PCB) Cost

The prices for the aluminum nitride boards can vary. This is dependent on several factors such as color, board size, later, thickness, and surface finish, etc. Also, there are some cases where the quantity can determine the Aln PCB cost. For cases like this, manufacturers and suppliers might give people some discount, especially those making a bulk purchase.

Applications of the Aln PCB (Aluminum Nitride PCB)

One reliable product which serves several applications is the Aln PCB. They are applicable in different areas due to the great features and properties found inside the product. You can use aluminum nitride in applications requiring electrical insulation and thermal conductivity.

The applications of Aln PCB include transportation inverters, cooling systems, LEDs, semiconductor industries, telecommunications, etc. Aln PCB is also important in abrasive environments due to their ability to fight against extreme temperatures. Also, it ensures that the device is risk-free.

Disadvantages of Using Aln PCB (Aluminum Nitride PCB)

Hardly will you find any pitfalls in the Aln PCB. Compared to other printed circuit boards, the Aln PCB (aluminum nitride PCB is very expensive. Moreover, whenever the drive involves thermal conductivity or electrical insulation, then aluminum nitride PCB boards stand out as the best.

Another disadvantage of making use of Aln PCB is aluminum nitride may be exposed through the mouth, injection, or via inhalation. This can cause bone and lung toxicity. However, despite all these disadvantages, aluminum nitride boards have been the best solution for several applications due to the high-quality properties that it possesses.
