Copper PCB

Industrial-grade copper circuit boards with 2oz-20oz copper layers, 25μm+ plating, and 20A/mm² current capacity. MIL-PRF-31032 and IPC-6012 Class 3 compliant for aerospace/military use.

What is a Copper PCB?

"Copper clad PCB boards utilize pure C11000 electrolytic copper foils (99.9% purity) for extreme current carrying capacity and thermal dissipation (385 W/m·K)."

Key Applications:

  • Power converters (1000A+ busbars)

  • EV battery management systems

  • Industrial motor drives
