Through my personal modification experience, I discovered that thick copper layers show significant advantages in handling high currents \u2013 they effectively reduce impedance, improve heat dissipation efficiency, and lower the temperature of the equipment by more than ten degrees Celsius at peak power. However, thick copper design is not simply about thickening the copper foil; it requires professional process adjustments to avoid lamination or drilling problems. This article shares the value of thick copper PCBs in practical applications and the details that need attention."}
