What are the benefits of use multilayer aluminum PCB?
There are several benefits of using Multilayer Aluminum PCBs:
Multilayer Aluminum PCB is a type of aluminum printed circuit board that consists of multiple layers of aluminum circuitry separated by insulating layers, typically made of prepreg or polyimide. It offers a number of advantages, such as high thermal conductivity, excellent heat dissipation, low thermal expansion coefficient, and good electromagnetic shielding performance, making it well-suited for applications in power electronics, LED lighting, automotive, aerospace, and other industries that require high power and high reliability.
The stackup of a Multilayer Aluminum PCB typically includes alternating layers of aluminum circuitry and insulating material, such as prepreg or polyimide. The specific stackup design may vary depending on the requirements of the PCB, but a common configuration is as follows:
The stackup may also include additional internal layers and ground planes depending on the specific design requirements. Vias and plated through holes are typically used to provide electrical connections between different layers. The precise stackup design is critical to the performance of the Multilayer Aluminum PCB, as it affects the electrical, thermal, and mechanical properties of the board.
