In PCB, in addition to metal materials, there are other materials that can conduct electricity and heat.
1. Graphene: Graphene is an emerging PCB board substrate material with excellent electrical conductivity, thermal conductivity and mechanical properties, and is also very lightweight. However, due to the high production cost of graphene, it is not widely used yet.
2. Metal substrate: Metal substrate is a PCB board that uses metal as the base material. It has high thermal conductivity and mechanical strength and is suitable for high-power electronic equipment and high-frequency electronic equipment.
