Metal PCB, also known as Metal Core PCB (MCPCB), is a type of printed circuit board where the base material is made of metal instead of the traditional glass fiber reinforced resin (FR-4). Metal PCBs offer excellent heat dissipation capabilities, good mechanical strength, and electromagnetic shielding, making them widely used in high-power electronic devices, LED lighting, and automotive electronics. Metal PCBs effectively reduce circuit temperatures, thereby improving the operational stability and reliability of electronic components.
