Backplane PCB

365PCB specializes in high-layer count backplane PCBs (up to 50 layers) and CPCI backplane solutions with 25Gbps signal integrity. MIL-STD-202H compliant with 15+ years defense/aerospace experience.

What Are Backplane PCBs?

Backplane PCBs serve as the backbone for high-speed systems, connecting multiple daughterboards via high-density connectors.

Highlight: Our CPCI backplane designs support hot-swapping for industrial computing.
