About Aluminum PCBs
Aluminum PCBs are built with layers of silkscreen, solder mask, and copper, along with a metal substrate that replaces the fiberglass commonly found in traditional boards.
The base material of aluminum PCBs integrates an FR4 layer and an aluminum core, offering exceptional heat conduction capabilities. These boards are ideal for high-power or tight-tolerance applications due to their superior thermal properties, which help in reducing thermal expansion, unlike copper or other materials.
The thermal layer in aluminum PCBs is designed to effectively dissipate heat, ensuring that your components stay cool and continue to operate efficiently. Partnering with a reliable metal-core PCB manufacturer can ensure optimal performance tailored to your unique thermal and mechanical needs.
Aluminum PCBs: Key Benefits
sing aluminum in your PCB manufacturing can enhance heat dissipation, minimizing thermal stress and circuit degradation.
Compared to fiberglass or ceramic materials, aluminum offers better durability and strength for electronic devices.
Aluminum is fully recyclable and non-toxic, making it a sustainable option. Its lightweight nature and ease of assembly contribute to reduced energy consumption during manufacturing.
Aluminum PCBs are known for their durability and light weight, offering the ideal combination of strength and resilience without adding unnecessary weight.
Thanks to aluminum's sturdy properties, these PCBs are resistant to damage during handling, transportation, and daily use, making them ideal for high-reliability applications.
Compared to other metal options, aluminum provides a more cost-efficient solution without compromising quality, making it ideal for high-volume production.
Aluminum excels at transferring heat away from sensitive components, enhancing the longevity and efficiency of your electronic devices by keeping temperatures in check.
Aluminum PCB Materials and Structure
Aluminum PCBs are a cost-effective solution for high-performance electronics. Available in single-layer, double-layer, and multi-layer designs, they are perfect for applications like LED lights, solar panels, and more.
Common aluminum substrate materials include:
- 6061: A versatile aluminum alloy with good strength and machining properties.
- 5052: Known for its excellent bending properties and resistance to corrosion.
- 3003 & 1100: Pure aluminum with excellent thermal conductivity.
The dielectric material used in our aluminum PCBs is a specialized polymer filled with ceramics, ensuring reliable insulation.
Rigid and Flexible Aluminum PCBs
At Mars PCB, we offer both rigid and flexible aluminum PCBs:
- Rigid Aluminum PCBs: These are commonly used in industrial, automotive, and communication applications. Available in 1-layer, 2-layer, and 4-layer designs.

We support both prototype and mass production of these PCBs to meet the specific needs of your project.
The Build Layout of Aluminum PCBs
Copper Foil Layer
- This layer is typically thicker than standard copper-clad laminates, usually ranging from 1 oz to 10 oz. The increased thickness improves the board’s current-carrying capacity and overall performance.
Dielectric Layer
- The dielectric layer, which ranges from 50 μm to 200 μm in thickness, offers excellent thermal conductivity. It is crucial for ensuring low thermal resistance, making it ideal for heat-sensitive applications.
Aluminum Base
- The third layer is an aluminum base, known for its high thermal conductivity, which ensures efficient heat dissipation and robust mechanical performance.
Aluminum Base Membrane Layer
- This protective layer prevents scratches and damage to the aluminum surface. Depending on the application, the membrane can be heat-resistant, with options up to 250°C.
