Best answer

Ordinary metals mainly play the role of electrical and thermal conductors in PCBs. In PCB, they are used to connect various components and wires on the circuit board to form electrical paths and realize the transmission of current. At the same time, these metal materials can also effectively dissipate heat from the circuit board and maintain the stability and reliability of the circuit board. Common common metals include aluminum, copper, iron, nickel, lead, tin and zinc.
