Copper base PCB uses a solid copper substrate as the metal core. Copper offers even higher thermal conductivity than aluminum, making copper base boards the first choice for extreme heat dissipation in high-power electronics.

Copper PCB Structure:
- Copper base: the solid copper core for maximum heat spreading.
- Thermally conductive dielectric layer.
- Copper circuit layer with fine traces.
- Solder mask and surface finish protect the board.

Key Advantages:
- Thermal conductivity up to 398 W/mK, far higher than aluminum.
- Excellent heat dissipation for high-current designs.
- Higher mechanical strength and rigidity.
- Superior electrical conductivity for power delivery.

Copper PCB Applications:
- High-power LED modules and laser drivers.
- Industrial power supplies and inverters.
- Automotive power electronics and battery management.
- High-frequency RF modules and microwave systems.

Choose copper base PCB when your application demands the ultimate thermal performance and high-current carrying capacity.
