Thick copper plates have significant advantages in carrying high currents, good heat dissipation, and reducing thermal strain, greatly reducing the risk of board burning and making them an excellent option for high current PCB design. In addition, thick copper plates can also increase the mechanical strength of circuit boards and reduce the volume of end products.
