Aluminum PCB (metal core PCB, MCPCB) uses an aluminum base layer combined with a thermally conductive dielectric. It dissipates heat efficiently, making it ideal for high-power LED lighting and power electronics.

Aluminum PCB Structure:
- Aluminum base: provides strength and heat spreading.
- Dielectric layer: thermally conductive, electrically insulating.
- Copper circuit layer: carries the electrical signals.
- Protective coating: solder mask and silkscreen.

Key Advantages:
- Excellent thermal conductivity, up to 1-3 W/mK through the dielectric.
- Lightweight and cost-effective.
- Good mechanical strength and EMI shielding.
- Long lifetime under high temperature.

Aluminum PCB Applications:
- LED lighting and street lights.
- Power supplies and motor drivers.
- Automotive lighting and battery systems.
- High-power RF and telecom equipment.

Choose aluminum PCB when your design needs efficient heat dissipation and reliable high-power performance.
