Aluminum Backed PCBs
Printed Circuit Board can be classified into different types according to different standard, such as single layer PCB, double layer PCB, and Multilayer PCB. But now we are going to introduce you the Aluminum-Backed PCBs.
Aluminum-backed PCBs are designed in much the same way as their copper-backed counterparts by using the aluminum or copper substrate board.
These types of boards have a thermal clad layer which disperses heat quite efficiently. At the same time, the layer is also cooling components which results in an increase in the overall performance of your PCB.

Let’s look at aluminum printed circuit boards a bit closer and figure out why we choose them. Here are some advantages of Aluminum-backed PCBs when come compared with fiberglass PCB boards.
1. Heat dissipation. This is the most obvious advantage. Aluminum is one of the best materials available for dissipating heat away from crucial components of circuit boards by transferring heat out into the open air to avoid too much heat on these components could result in severe damage to your board.
2. Low cost. Aluminum is easy and inexpensive to mine, which helps to cut expenses in manufacturing process. Thus, building products with aluminum is less expensive.
3. Environmentally friendly. Aluminum is non-toxic and easily recyclable, causing less effect to the environment.
4. Longer lifetime. Unlike the other materials on the board, such as the copper foil and insulation, aluminum PCBs will be less likely to peel away, further lengthening the lifetime of the product.
All of these advantages make Aluminum PCBs become an excellent choice for applications require high outputs of power within very tight tolerances. They are widely used in automotive and power electronics, and anything else that heat would be harmful to the components such as LED lighting, the largest usage for the Aluminium-based PCBs.
