A metal PCB, also known as a metal core PCB (MCPCB) or metal-backed PCB, is a type of printed circuit board that has a metal core layer instead of the traditional fiberglass epoxy substrate found in standard PCBs. The metal core provides improved thermal conductivity and heat dissipation capabilities, making metal PCBs suitable for applications requiring efficient heat management.
The metal core typically consists of aluminum, copper, or alloy materials, with aluminum being the most common choice due to its lightweight and cost-effectiveness. The metal core serves as a heat sink, helping to dissipate heat generated by power components or high-power LEDs mounted on the PCB.
Metal PCBs are commonly used in various high-power and high-temperature applications such as LED lighting, automotive lighting, power converters, motor controllers, and solid-state relays. The design and manufacturing processes for metal PCBs are similar to those for standard PCBs, with additional considerations for thermal management and compatibility with metal substrates.
