standard thickness of the copper layers. Often a thickness of 35 or 70 µm are used by PCB manufacturers. The choice of thickness of the layers plays an important role for the temperature rise in the windings induced by the currents. Safety Standards like IEC 950 require a distance of 400 µm through PCB material (FR2 or FR4) for mains
