Aluminum PCBs are widely used in LED lighting, power conversion, automotive modules, and products where heat must leave the board quickly.
Main advantage
The metal core improves heat transfer compared with standard FR4. That helps LEDs and power devices run cooler and more reliably.
Typical applications
- LED modules
- Power supplies
- Automotive lighting
- Motor drivers
If your product is thermally limited, aluminum PCB may be a better solution than simply increasing copper on FR4.
