Metal PCB boards, also known as thermal PCB or metal back PCB, are based on metal materials and used for the heat dissipation part of the board. The metal core provides better thermal conductivity, reducing operating temperature and improving overall performance and reliability of electronic devices. Metal PCBs are more compact and lightweight compared to traditional PCBs, making them ideal for applications where space and weight are critical factors. They also provide electromagnetic shielding and are suitable for applications in which electromagnetic interference needs to be minimized. Metal PCBs offer a range of benefits for various applications, including improved thermal management, reduced size and weight, and enhanced electrical performance. They have high mechanical strength, excellent processing performance, good heat dissipation, good magnetic conductivity, and high tensile modulus, and are widely used in applications involving cooling issues and the use of a large number of LEDs.
