The Advantages of Aluminium PCB Boards

Among all metal core printed circuit boards, Aluminium PCBs are the most common type - the base material consists of aluminium core with standard FR4. It has a thermal cladding that allows efficient heat radiation while cooling the parts and improving the overall performance of the product. At present, Aluminium PCBs is considered a solution for high power and high tolerance applications.

Advantages of Aluminum PCB boards contain following aspects：
✅Non-toxic
In this era of global warming, most manufacturing companies are trying to come up with products that will not damage or degrade the environment. Aluminum is environmentally friendly and recyclable, making it an ideal material for PCBs. PCBs are utilized in electronic equipment, and aluminium is the most practical material because it has no negative impact on the environment.

✅Unique and highly effective
Aluminum PCB is made of three layers. The circuit layer is made of copper, the dielectric layer is made of low resistance insulation material, and the base is made of aluminum. The dielectric layer contributes greatly to the effectiveness of the aluminium PCB because it conducts 5 to 10 times more heat than epoxy glass. This means that it will be able to transfer heat from the device being used.

✅Great heat radiator
Aluminum dissipate a lot of heat compared to basic FR4-based printed circuit boards. This means that it is more suitable for devices that release a lot of heat because aluminium effectively disperses heat. Equipment that needs to be cooled is made of aluminium sheets to prevent damage.

✅Affordability and availability
Aluminum is cheaper than copper, forged iron, brass or stainless steel, making it a suitable material for printed circuit boards. Manufacturer always keep in mind the cost of their equipment. Aluminum is an ideal material for making printed boards because of its price.

Most importantly, aluminium is available in many climatic conditions around the world and is therefore easy to refine and extract. Compared with other materials, the availability of aluminium makes it easier to manufacture large volume of printed circuit boards at affordable costs.

The availability of aluminium reduces the cost of making printed circular plates, and in return, the total price of the product is lower.This has a positive impact on consumers, as equipment made from aluminium PCB will be a little more affordable than products made from printed circular plates with substrates other than aluminium.

✅Effective thermal conductivity
Aluminum PCBs conduct and transfer heat from critical areas that may damage electronic equipment. A good example is led, which produces a lot of light and heat, while aluminum effectively diverts heat from the device. It is likely that the circuit damage is minimal, which will enhance the product life.

✅Versatility
Aluminum PCB can be utilized to make a series of products. These include but are not limited to computer central processing unit board, voltage regulator switch, high frequency amplifier, motor driver, automobile electronic voltage regulator and other electronic equipment.

The versatility of aluminum makes it an outstanding material because it simplifies the manufacturing process. Due to the availability and functionality of aluminum, many devices that require PCBs can be easily manufactured.

✅Higher durability
Aluminum boards are very strong and provide additional toughness, which is an additional advantage due to minimal damage. Accidents do occur during manufacturing, but aluminium boards are easy to handle because they are less fragile than ceramic or glass fibre substrates.

Durability makes them easier to use on a daily basis during manufacturing. The manufacturers’ goal is to reduce production costs, one of which is to ensure that the products used are not easily damaged because they can cause losses.

✅Improve reliability
Aluminum is more reliable and less likely to be damaged than ceramic and fiberglass substrates used to make PCBs. Like other bases, it's not brittle, and it's better than ceramics and glass.

Additionally, the aluminum PCB is suitable for high-voltage devices due to its strength and the ability to withstand stress. Due to its quality and reliability, these characteristics make aluminum the greatly desired material for manufacturing PCBs.
