There is no such difference between aluminum and other PCB. All of these circuit boards have the same type of layout, but this circuit system uses various copper layers along with the solder mask. Furthermore, it also adds a silkscreen layer over these copper layers. On the other hand, many other boards have to use fiberglass as their substrates, or sometimes, plastic also utilizes for this purpose. 

However, the Aluminum PCB uses metal for substrate material rather than conventional ones. Moreover, the combination of metal along with fiberglass is widespread in this sort. The most common type of this PCB is single-sided. Apart from this, we can use double-sided, which is very rare in this sort.

These circuits are most common in the case of heat removal such as LED as well as some other electronic device. When we use LED in our daily life and it produces intense light which leads to the heat issue. On the other hand, the layers of aluminum help to remove heat from LED, which leads to prolife the average life of this device. This is the main example of why this type of circuit is essential in this modern era.

There are three layers in the assembly of this PCB. The first one is the aluminum layer which is used as a base or substrate for another layer, and it is a very high thermal conductor layer. Secondly, the dielectric layer is located in the middle of these layers. In the last, the copper layer is situated on the top of the system, which is thicker as compared to other ones and it has more capacity to store the current in it.

Type of Flexible Aluminum 

There are three most common types of this type of PCB

1.  Flexible Aluminum PCB

In this sort, the dielectric is flexible and it is composed of ceramic along with aluminum material, which can boost the thermal efficiency of this material. Furthermore, we can fold these materials regardless of any harm.

1. Hybrid Aluminum PCB

In this type, engineers design non-thermal material along with thermal material such as aluminum. By the means of these products, we can produce a hole in the side of these layers, which help to pass different cables and enhance the design of this system.

1. Multilayers Aluminum PCB

In this type, we can add multiple layers according to the design of the products and we can easily boost the performance of these products.

Why Aluminum PCB is essential in this modern era?  

The most common problem in different electronics is heat which we need to remove to improve the life of these devices. In this particular condition, aluminum can perform in a better way as compared to other ones, namely fiberglass. Furthermore, engineers need durability in the various product that can provide by the means of metal rather than some ceramic or other materials. 

Advantages of Aluminum PCB

There are plenty of benefits of this modern PCB due to its extraordinary property as compared to its counterpart board. There are the following advantages of Aluminum that make this circuit unique.

• Reduction in Cost: Aluminum is a widespread element in our world. Therefore, there is no such hindrance in the process of refining this metal as compared to other metals. In this way, the cost of the board can reduce dramatically if we use aluminum for the production of PCB. Therefore, the usage and demand of this metal in increasing with time.

• Environmentally Friendly: The trend of repairing anything is very rare in our society. Hence, we should use only those materials that are environmentally friendly. Therefore, this condition could be fulfilled through Aluminum that is non-toxic, and we can easily recycle this material, which is an enormous amount of money. In this way, we can enhance the environment of our earth. 

• Removal of heat: The main problem of different electronic things is heating when we have used these devices for a long time. Therefore, we need to find such material that could help to mitigate this issue. On the contrary, this problem can be resolve by the means of Aluminum, which is very good metal in a heat removal case. In this way, it reduces damages of different products due to these problems.

• Lightweight: Weight reduction is also a very essential factor if we want to maintain the position of different products in this modern era. It is very amazing to note one thing that aluminum is very low weight as compared to other material that used in other PCB. Therefore, the use of this metal is growing day by day.

• Durability: This factor is inevitable in this modern era. Aluminum has extraordinary performance in this field. Because it has more strength as compared to other materials, such as glass fiber, which is commonly used in another type of circuit board system. For this purpose, the utilization of Aluminum is increasing with time.

Applications of Aluminum PCB

There is plenty of application of these type in our daily, but we will mention few of them, which are very common in our life.

• The use of aluminum PCB is very common in an audio device, such as a power amplifier.
• Wherever we need to provide power supply then engineers use this system for interconnection, namely, AC and DC converters are the main example of logic.
• The use of this PCB in computer and other automation devices are widespread due to its extraordinary properties.

• The usage of this circuit in automobiles is very normal due to its properties. For example, the use of this PCB in a power supply controller is very common.
• The demand for power modules is also increasing with time. For instance inverter as well as rectifier bridges
• The connection in the communication is mostly connected by the means of this PCB, such as the transmitter circuit.
• The use of this circuit board in different lights and lamps is very common. The main reason behind this use is that engineers need to remove heat from such devices, such as LED light. These conditions can fulfill through the use of Aluminum PCB.
