- Overview of Aluminum Substrate
Aluminum core PCBs are the most common type of metal core PCBs. The base material consists of an aluminum core and standard FR4. It features thermal cladding to efficiently dissipate heat while cooling components and improving the product's overall performance. Aluminum Backed PCBs are currently considered the solution for high power and tight tolerance applications.

• Advantages of aluminum substrates
The aluminum PCB has the advantages of environmental protection: the aluminum material is non-toxic and recyclable. Using aluminum for circuit boards is beneficial for saving energy because it is easy to assemble. For printed circuit board suppliers, using this metal helps protect the planet's environment. |
The aluminum PCB has good heat dissipation: It is well known that high temperatures can cause serious damage to electronic products, so it is wise to use materials that help heat dissipation. aluminum, on the other hand, can dissipate heat away from critical components, thereby minimizing its harmful effects on the circuit board. |

The aluminum PCB have better durability: Aluminum materials provide circuit board products with strength and durability that ceramic or fibreglass substrates cannot. And aluminum is a strong substrate that reduces accidental breakage during manufacturing, handling, and everyday use. |
The aluminum base plate is lightweight: Aluminum is not only incredibly durable but also a lightweight metal. aluminum adds strength and toughness without adding any extra weight.

• Aluminum PCB layer
aluminum PCB is a unique layering system consisting of the following layers: |
- Circuit layer: Printed circuit foils are 1 oz to 5 oz thick.
- Dielectric layer: |
- Dielectric layer: Some options can be available for dielectric layers, which provide electrical isolation with minimal thermal resistance. It is also used to bond circuit layers and substrates together. Each specific dielectric has its UL certification. Please see the list below for various options for our stock materials to ensure fast delivery. |
• Aluminum PCB Applications
Below are some examples of applications using aluminum PCBs.
|
- Power Conversion aluminum clad offers a variety of thermal performances, is compatible with mechanical fasteners, and is highly reliable. |
|
- Motor Drives Thermal-clad dielectric choices provide the electrical isolation needed to meet operating parameters and safety agency test requirements.
- Solid State Relays aluminum offers a very thermally efficient and mechanically robust substrate to drive heat away from critical system components.
- Automotive Electronic regulator, ignition, power supply controller, etc.The automotive industry uses aluminum boards, as they need long-term reliability under high operating temperatures coupled with their requirement of effective space utilization. Most commonly used in automotive lighting system components.
- Consumer Products Most commonly found in street lighting, traffic control lighting, interior building lights, landscape lighting, and camping gear, aluminum PCBs are lightweight and very small. |
