Stack up of Multilayer Aluminum PCB

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:

Multilayer Aluminum PCB Stack up
  • Top layer: Copper layer for component mounting and signal routing
  • Insulating layer: Prepreg or polyimide
  • Internal layer 1: Aluminum layer for power distribution and heat dissipation
  • Insulating layer: Prepreg or polyimide
  • Internal layer 2: Aluminum layer for power distribution and heat dissipation
  • Insulating layer: Prepreg or polyimide
  • Internal layer 3: Aluminum layer for power distribution and heat dissipation
  • Insulating layer: Prepreg or polyimide
  • Bottom layer: Copper layer for component mounting and signal routing

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.


What are the benefits of use multilayer aluminum PCB?

There are several benefits of using Multilayer Aluminum PCBs:

High thermal conductivity

Aluminum has high thermal conductivity, which means it can quickly dissipate heat generated by components on the board, improving the overall reliability and lifespan of the system.

Excellent heat dissipation

The metal core of the Multilayer Aluminum PCB acts as a heatsink, which can effectively dissipate heat from the components to the surrounding environment.

Low thermal expansion coefficient

The coefficient of thermal expansion (CTE) of aluminum is close to that of silicon, which is commonly used in electronic components, making Multilayer Aluminum PCBs less prone to mechanical stress caused by temperature changes.

Good electromagnetic shielding performance

Aluminum has good electromagnetic shielding properties, which can reduce electromagnetic interference (EMI) and improve the overall performance of the system.

Higher power density

Multilayer Aluminum PCBs can handle higher power densities due to their improved thermal management capabilities, which makes them ideal for high power applications.
