Improve Circuit Board Reliability and Reduce Failure Rate
What Is Metal Base PCB
A Metal Base PCB is a type of circuit board that has a metal base layer, usually made of aluminum or copper, instead of the traditional epoxy or fiberglass substrate found in standard printed circuit boards. The metal base provides several advantages, making it suitable for specific applications where enhanced thermal performance is crucial.
☑ Widely compatible circuit design adapts to various devices
☑ Enhance mechanical strength to adapt to harsh working environments
☑ Simplify heat dissipation design and reduce PCB board production costs
☑ Adapt to high-power applications and meet electronics circuit complex needs
☑ Reduce electromagnetic interference and improve anti-interference ability
