Manufacturing process and advantages of aluminum printed circuit board PCB

Introduction of aluminum printed circuit board PCB
Aluminum printed circuit boards PCB have the ability to dissipate heat from electronic products. Aluminum PCB is one of the most commonly used types. It has standard FR4 laminate and aluminum core. The circuit board effectively helps to dissipate heat with the help of its characteristic thermal insulation layer. These printed circuit boards are most widely used in applications involving tight tolerances and high power.


 
Manufacturing Process of aluminum printed circuit board PCB
During the manufacture of an aluminum printed circuit board PCB, a thin dielectric layer is added between the circuit layer and the base layer. The dielectric layer is both electrically insulating and thermally conductive. After adding the dielectric layer, the circuit layer or copper foil is etched. This allows you to get the desired pattern. The metal base layer of the circuit board helps remove all heat from the circuit with the help of a thin dielectric layer.
 
Advantages of aluminum printed circuit board PCB
1. Lightweight: Aluminum is an extremely light metal. Therefore, it helps to increase the strength and elasticity of the PCB.
2. Heat dissipation: Aluminum is a material that is able to carry the heat generated away from the vital components on the board, protecting them from any potential damage.
3. Long lasting: Aluminum is a strong and durable material with high durability. By using an aluminum circuit board, the risk of accidental breakage during handling, manufacturing or everyday use is eliminated. It can provide better strength to products compared to fiberglass and ceramic substrates.
4. Environmental protection: aluminum printed circuit board PCB is easy to assemble and helps to save energy. Apart from that, the material is recyclable and non-toxic.
5. Economy: Aluminum is cheaper than other metals, and aluminum is easy to mine and refine, which helps keep costs down.
