What Makes Copper Core PCBs Different From Standard Circuit Boards?
Copper core PCBs differ from standard circuit boards through their specialized multi-layer structure designed for superior thermal performance. The foundation of every metal core printed circuit board is a solid copper plate that efficiently conducts heat away from critical board components. This metal substrate is covered with a high-performance insulated metal layer that provides electrical isolation while still allowing heat transfer. Copper PCBs are then topped with copper foil where components are mounted.

Yes, OurPCB offers advanced PCB solutions including 8-layer copper core PCB designs. Our copper base PCBs support complex multilayer structures with various PCB materials and copper layers to meet your specific requirements. We excel in PCB fabrication and assembly for projects requiring these specialized capabilities.
What testing verifies the performance of your copper core circuit boards?
Our copper core PCB suppliers conduct comprehensive thermal validation using infrared thermography. This testing verifies actual heat dissipation across the entire board surface and identifies potential hot spots. Our PCB factory also performs reliability testing to ensure consistent performance under various operating conditions.
