Today we are here to discuss its beneficial uses in PCB aluminum. So, let’s dive in!

What is PCB aluminum?

The aluminum PCB circuit boards are actually the boards that have a very thin layer of conductive material. These circuit boards are also famous as,

  1. Aluminum base
  2. Aluminum clad
  3. Metal Coe Printed Circuit Boards (MCPCB)
  4. Thermally Conductive PCBs
  5. Insulated Metal Substrate (IMS).

Today in several other MCPCB boards, aluminum PCB boards are very popular. In these circuit boards, electronic designers use aluminum alloy as a base instead of using the fiber glass base. Moreover, designers use this alloy in order to provide highest thermal conductivity and electrical insulation.

In fact, in PCB aluminum, the aluminum protects all components of the electronic device from extra heat. Actually, it provides the better stability to the modern and complex electronic devices.

Today this special aluminum substrate is very common to use in LED industry. Additionally, these boards have great efficiency that several other important industries are also depending on them. So, they are rapidly making use of aluminum circuit boards in all their special devices.

What are other important categories of PCB aluminum? 

According to some important characteristics, electronic engineers have divided  PCB boards into three important categories. Such as,

  • High-frequency Aluminum PCB
  • High Thermal-Conductive Aluminum PCB
  • Universal Aluminum PCB.
High-frequency Aluminum PCB:

In this type of PCBs boards, electronic designers create the dielectric layer by combining

polyimide or polyolefin resin glass fiber pre-preg.

  • Microwave
  • Radio frequency
  • Mobile phones
  • Applications of high-speed designs, etc.
High Thermal-Conductive Aluminum PCB:

In this type of aluminum PCB circuit boards designers creates dielectric layer by making use of epoxy resin. In addition, this resin contains highly thermal conductivity.


These type of aluminum PCB boards are ideal to use in all LED applications. Like,

PCB aluminum

  • Automotive lighting
  • Traffic lights
  • General lighting and so on.
Universal Aluminum PCB:

In this kind of aluminum PCB boards, designers fabricate the dielectric layer with the help of epoxy glass fiber pre-preg.

  • Industrial power equipment
  • High-power audio equipment
  • Semiconductor refrigeration devices
  • Thermal printer heads
  • Solar cell substrate
  • Automotive applications and many, many more

Why PCB aluminum are perfect choice to use in LED industry?

Basically, Aluminum is a perfect choice to use in highly advanced LED industry. Because aluminum has many advantages to use in aluminum PCBs. Actually, it is low cost in comparison to other metals, such as, steel and copper. Moreover, aluminum is extremely light weight and has greater durability.

Aluminum has great abilities of heat transferring. So, all these important reasons have made aluminum PCB boards highly advantageous in LED industry.

4 reasons to use PCB aluminum in LED industry

There are many reasons to use aluminum PCB boards in LED industry. But we are here to discuss top 4 reasons among several others. Moreover, these are:

1) Extremely light weight:

As we have already described that aluminum is very light in weight. So, aluminum boards are also very light in weight. Hence, the applications which use aluminum boards will be absolutely light in weight. The devices which use aluminum circuits will be very easy to handle.

2) Extremely better to avoid several damages:

Actually, heat is the major factor to control in electronic devices. So, it can damage your expensive and helpful gadgets. In such circumstances, aluminum PCBs are best to use. Because aluminum has ability to transfer heat away from all the vital components of electronic appliances.

By using aluminum PCB circuit boards, you can avoid many damages as they are 10 times extra reliable and efficient.

3) Cost effective:

Basically, aluminum is the only metal which you can find everywhere in almost all climates. Furthermore, it is extremely easy to mine as well as refine. So, PCB aluminum boards are inexpensive to use in LED industry.

4) You can increase LED density:

When manufacturers use fiber glass designs, they have to use a smaller number of LEDs on the board. But when they use aluminum substrate, they can easily increase the number of LEDs on the board. Because aluminum substrate helps to reduce as well as transfer heat away from the board.

Moreover, aluminum has great thermal conductivity. So, aluminum PCBs are highly beneficial to use in LED industry.
