Aluminum PCB boards are also known as metal core printed circuits, insulated metal substrate, aluminum clad, or aluminum base. They are metal-based and copper-clad laminates that are used to make electronics or other devices that require a lot of cooling. Aluminum PCBs make perfect thermal conductors for devices that generate a lot of heat, power switches, and power converting electronics.
Aluminum PCBs became famous in the 1970s, and back then, they were used in integrated circuits or amplified hybrid integrated circuits. Many advancements have taken place since then, and aluminum PCBs are now widely used and are made as a single layer or double layer printed circuit boards.
What are some of the advantages of Aluminum PCB boards?
They are unique and highly effective
Aluminum PCBs are made of three layers. The circuit layer made of copper, a dielectric layer made of insulating material that has low resistance and a base layer made of aluminum. The dielectric layer contributes a lot to the effectiveness of aluminum PCBs because it is 5 to 10 times more thermally conductive than the epoxy glass. This means it will be able to conduct heat away from the device being used.
Cheap and easily available
When compared to copper, wrought iron, brass, or stainless steel, aluminum is more affordable, making it a suitable material for printed circuit boards. Manufacturing companies always put in mind the production cost of devices, and aluminum is the perfect material for making printed circular boards due to its price.
On top of that, aluminum is available in many climatic conditions globally hence easy to refine and mine. Availability of the aluminum makes it easier to manufacture a vast of printed circuit boards at an affordable cost compared to the other materials.
The availability of aluminum lowers the manufacturing cost of the printed circular boards, and in return, the overall price of the products is lower. This leads to a positive impact on consumers because the devices made from aluminum PCBs will be a bit affordable compared to products made with printed circular boards from other substrates other than aluminum.
Great heat radiator
Aluminum dissipates a lot of heat compared to the basic FR4 based printed circuit board. This means that it is more suitable for devices that release a lot of heat since the aluminum will scatter the heat effectively. Devices that need cooling are made with aluminum PCBs to prevent them from getting damaged.
Aluminum PCBs are very sturdy and provide extra tenacity, which is an added advantage due to minimal breakages. Accidents do happen in the manufacturing process, but aluminum PCBs are easy to handle because they are not fragile and will not break easily compared to ceramic or fiberglass bases.
The durability makes them more convenient for everyday use in the manufacturing process. Manufacturing companies aim at lowering the production cost, and one of the ways is by ensuring the products being used are not easily damaged because it will lead to losses.
Ceramic and fiberglass bases are also used for making printed circular boards. However, they are not as feathery as aluminum, and this makes aluminum to have the edge over them. Aluminum is not bulky to carry, which makes the printed circular boards more economical in the end.
Aluminum printed circular boards are a huge improvement from the first printed circular boards, which were wired end to end on a chassis. These circuits were bulky, fragile, large, and heavy. The cost of production of making these products was high, not to mention labor-intensive. This, in return, made the products expensive.
In this era of increased global warming, most of the manufacturing companies are striving to come up with products that will not harm or degrade the environment. Aluminum is environmentally friendly, and it can easily be recycled, making it the perfect material for printed circular boards. A lot of devices and electronics currently have printed circular boards, and aluminum is the most realistic material to use since it does not negatively influence the environment.
Effective thermal conductivity
Aluminum PCBs conduct and transfer heat from critical areas that may damage electronics. A good example is LEDs, which produce a lot of light, creating immense heat, and the aluminum effectively directs the heat away from the device. Therefore, there is minimal circuit damage, which will intensify the lifespan of the product.
Aluminum PCBs can be used to manufacture an array of products. These include but not limited to computer central processing unit boards, Switches in regulators, High-frequency amplifiers, Motor drives, electronic regulators for cars among other electronic devices.
The versatility of aluminum makes it a prominent material because it simplifies the manufacturing process. Many devices that need a printed circular board can easily be manufactured due to the availability and functionality of aluminum.
When compared to ceramic and fiberglass bases used for making printed circular boards, aluminum is more reliable and has fewer chances of being damaged. It is not fragile, like the other bases, and it is stronger than both ceramic and glass.
In addition to that, aluminum PCBs are suitable for high-pressure devices due to their strength and ability to withstand stress. These attributes make aluminum to be the most sought after material for making printed circular boards due to its quality and reliability.
Aluminum printed circular boards have made a notable impact in the manufacturing of electronics and other appliances that generate a lot of heat. Their spectacular ability to conduct heat and transmit it away from critical parts of the device is what makes them stand out.
Aluminum is also non-toxic, readily available, and can be recycled as a means of conserving the environment. Not forgetting the versatility that comes with using aluminum for manufacturing a myriad of products. These advantages continue to make aluminum the perfect choice for making printed circular boards that are durable and reliable at the same time.
