What is 2 Layer Aluminum PCB?
2-layer aluminum PCB, or double-sided aluminum PCB is a type of aluminum printed circuit board that features a thin layer of aluminum on both sides of the board, providing excellent heat dissipation and thermal management properties. The aluminum layer acts as a heat sink, allowing the board to dissipate heat more efficiently than traditional PCBs.
Common specifications for 2 layer aluminum PCBs are:
> Aluminum thickness: 0.8mm to 3.0mm> Dielectric layer thickness: 0.1mm to 0.3mm> Copper thickness after plating: 20μm to 35μm> Minimum track/spacing: 6mil/6mil (0.15mm/0.15mm)> Minimum hole size: 0.3mm> Hole to hole spacing: 0.6mm> Finished board thickness tolerance: ±0.1mm
The two aluminum layers are typically connected by a series of vias, which allow for electrical connections to be made between the top and bottom layers of the board. The vias are typically drilled through the core material and then plated with copper to create a conductive path between the two aluminum layers.
On top of the aluminum layers, a layer of copper is applied, which is then etched away to create the desired circuit pattern. The remaining copper traces and pads are then coated with a layer of solder mask to protect them from oxidation and to provide insulation between the copper and other components on the board.
Finally, a silkscreen layer is applied to the board, which is used to label the various components and provide other information about the board, such as the manufacturer’s logo or part number.
Overall, the structure of a 2-layer aluminum PCB is similar to that of a traditional 2-layer PCB, but with the added benefit of improved thermal performance thanks to the use of aluminum layers as heat sinks.
The structure of a 2 layer aluminum PCB typically consists of a thin layer of aluminum foil that is laminated to both sides of a core material, such as FR-4 or ceramic. The core material provides the structural integrity of the board, while the aluminum layers act as a heat sink to dissipate heat generated by the components on the board.
The Structure and Components of 2 Layer Aluminum PCBs
The use of aluminum in double sided aluminum PCBs also makes them more durable and reliable than other types of PCBs. Aluminum is highly resistant to corrosion and oxidation, which helps to prevent the degradation of the board over time.
Improved reliability
Easy to design and manufacture
Double sided aluminum PCBs can be designed and manufactured using standard PCB fabrication processes, which makes them easy to integrate into existing designs and manufacturing processes.
Despite their many advantages, double sided aluminum PCBs are relatively cost-effective compared to other types of high-performance PCBs. This makes them a popular choice for applications where cost is a concern.
Cost-effective
High power handling capacity
Double sided aluminum PCBs can handle higher levels of power than other types of PCBs, thanks to their excellent heat dissipation properties. This means they can be used in applications that require high power levels, such as power electronics, automotive electronics, and LED lighting.
Excellent heat dissipation
Double sided aluminum PCBs are designed with a thin layer of aluminum on both sides of the board, which provides excellent thermal conductivity and helps to dissipate heat more efficiently than other types of PCBs. This makes them ideal for high-power applications where heat management is critical.
Double sided aluminum PCBs offer several unique features and benefits that make them a popular choice for a variety of applications. Here are some of the key features of double sided aluminum PCBs:

Applications of Double Sided Aluminum PCB
Double sided aluminum PCBs are widely used in a variety of applications that require high thermal performance and reliable operation. Here are some of the key applications of double-sided aluminum PCBs:
1. LED Lighting: High-power LED lighting systems require efficient thermal management to ensure reliable and long-lasting operation. Double-sided aluminum PCBs provide excellent heat dissipation, making them an ideal choice for LED lighting applications.2. Automotive Electronics: Automotive electronics often operate in high-temperature environments, making reliable thermal management critical. Double-sided aluminum PCBs can handle high power levels and dissipate heat effectively, making them well-suited for automotive applications such as power modules, LED headlights, and motor control systems.3. Power Electronics: Power electronics, such as power supplies and inverters, generate a lot of heat and require efficient thermal management to ensure reliable operation. Double-sided aluminum PCBs are capable of handling high power levels and dissipating heat effectively, making them an excellent choice for power electronics applications.4. Telecommunications: Telecommunications equipment, such as base stations and routers, require reliable and efficient thermal management to ensure optimal performance. Double-sided aluminum PCBs can handle high power levels and dissipate heat effectively, making them well-suited for telecommunications applications.5. Medical Devices: Medical devices often require precise temperature control and reliable operation, making efficient thermal management critical. Double-sided aluminum PCBs can provide reliable operation and precise temperature control, making them a popular choice for medical device applications.
Overall, the superior thermal performance and reliability of double-sided aluminum PCBs make them an excellent choice for a wide range of applications where thermal management is critical.
As shown in the table, double-sided aluminum PCBs offer better thermal and electrical performance compared to single-sided aluminum PCBs due to their two layers of aluminum and thicker copper layers. They also have higher component density capabilities, making them ideal for more complex designs.
Multilayer aluminum PCBs can offer higher component density than double-sided aluminum PCBs due to their multiple layers, but they also require a more complex manufacturing process and are typically the most expensive option.
Overall, the choice between double-sided aluminum PCBs, single-sided aluminum PCBs, and multilayer aluminum PCBs depends on the specific requirements of the application, including component density, electrical performance, thermal performance, and cost.
Differences between Double Sided, Single Sided, and Multilayer Aluminum PCBs
Here’s a comparison of the differences between double-sided aluminum PCBs, single-sided aluminum PCBs, and multilayer aluminum PCBs:
The manufacturing process for double sided aluminum PCBs involves several steps. Here is an overview of the process:
1. Substrate preparation: The first step is to prepare the aluminum substrate. The substrate is cleaned and coated with a layer of dielectric material, which acts as the insulating layer between the two layers of aluminum.
2. Imaging and etching: The next step is to image the PCB design onto the substrate using a photoresist. The photoresist is exposed to UV light through a mask and then developed to remove the unexposed areas. The substrate is then etched to remove the exposed aluminum, leaving behind the circuit traces.
3. Drilling: After the circuit traces are formed, the PCB is drilled to create the necessary holes for component mounting.
4. Plating: The PCB is then plated with a layer of copper to increase its conductivity and provide a surface for component mounting. The plating process involves several steps, including cleaning, etching, and deposition of the copper layer.
5. Solder mask and silkscreen: Once the copper layer is in place, the PCB is coated with a layer of solder mask to protect the circuit traces and prevent solder bridging. A silkscreen layer is also applied to add component labels and other markings.
6. Surface finish: Finally, a surface finish is applied to protect the copper and prevent oxidation. Common surface finishes for double-sided aluminum PCBs include HASL (hot air solder leveling), ENIG (electroless nickel immersion gold), and OSP (organic solderability preservatives).
Once the PCB is complete, it undergoes a series of quality control checks to ensure that it meets the necessary specifications and standards. The PCB can then be shipped to the customer for use in their application.
