What are Metal Core PCB?
Metal Core PCBs (MCPCBs) are printed circuit boards with a metal base, typically aluminum or copper, for efficient heat dissipation. They improve thermal management, making them ideal for high-power and high-heat applications like LED lighting and power electronics. MCPCBs enhance performance and reliability by reducing heat buildup.
If you’re working on projects that include Passive Infrared (PIR) Sensors, MCPCBs offer excellent thermal performance and are an ideal choice.
