What is Single Sided Aluminum PCB?

A single-sided aluminum PCB has a bare aluminum base plate as the core, with a layer of dielectric laminate and copper traces on one side. The aluminum base plate is typically 0.5mm to 3mm thick and made of aluminum alloys like 5052, 6061, or 7075 for optimal thermal and mechanical performance. The dielectric layer is screen printed or bonded to the aluminum, followed by copper patterning to form the circuits.

Compared to other types of PCBs, Single Sided Aluminum PCB has the following differences:

Unlike double-sided or multilayer PCBs, it has only one copper foil circuit layer.
The aluminum substrate provides better heat dissipation performance due to its excellent thermal conductivity.
Single-sided aluminum PCB is typically used in electronic devices that require high power handling and heat dissipation, such as LED lighting, automotive electronics, and computer equipment.

Due to the unique properties of the aluminum substrate, single-sided aluminum PCB has a wider range of applications and higher reliability, especially in applications where excellent heat dissipation performance is required.

Single Layer Aluminum PCB Stack up & Structure.

Single Sided Aluminum PCB Stack up

Single Sided Aluminum PCB stack up refers to the arrangement of the layers in the PCB. As the name suggests, single sided aluminum PCBs have only one copper foil circuit layer on one side of the aluminum substrate.

The stack up for a single sided aluminum PCB typically includes the following layers:

Copper Foil Circuit Layer: This layer contains the circuit pattern that is used to connect the various electronic components.
Dielectric Layer: This layer is made up of a non-conductive material, such as epoxy or polyimide, and is used to insulate the copper circuit layer.
Aluminum Substrate Layer: This layer serves as the foundation of the PCB and provides excellent thermal conductivity for efficient heat dissipation.

The stack up for a single sided aluminum PCB is relatively simple compared to other types of PCBs. However, it is still important to ensure that the stack up is designed correctly in order to achieve optimal performance and reliability.

Benefits of Single Layer Aluminum PCB

Advantages of Single Layer Aluminum PCBs

Single Sided Aluminum PCB has excellent performance and reliability, suitable for applications that require high power handling and excellent thermal performance

Single Layer Aluminum PCB Manufacturing Process

The manufacturing process of Single Sided Aluminum PCB typically includes the following steps:

Material preparation: Prepare materials such as aluminum substrate, copper foil, drilling plate, etching solution, deposition solution, etc.
Copper foil lamination: Paste the copper foil onto the aluminum substrate and firmly fix it on the substrate through a hot pressing process.
Graphic drawing: Use printing plate-making technology to draw circuit graphics and component installation positions on the copper foil.
Drilling: Use automatic drilling machines or mechanical drill bits to drill holes at specified positions for the next step of circuit board connection.
Etching: Put the circuit board into an etching solution to remove unwanted copper foil, leaving only the required circuit paths.
Deposition: Deposit a protective coating on the circuit board to protect it from environmental impacts and mechanical damage.
Final inspection: Use professional testing equipment to test key parameters such as electrical performance, mechanical strength, and temperature resistance to ensure that the circuit board quality meets the requirements.
Cutting and punching: According to customer requirements, use cutting tools and drilling machines to cut the circuit board into the specified size and shape.
Packaging and shipping: Package the circuit board, mark it according to customer requirements, and ship it.
