In the high-speed PCB design, the clock and other key high-speed signal lines need to be shielded. If there is no shielding or only partial shielding, EMI leakage will be caused. It is suggested that the shielding wire should be grounded by drilling every 1000mil.

Switching regulators for voltage conversion use inductors to temporarily store energy. These inductors are usually very large in size and must be positioned in the printed circuit board (PCB) layout of the switching regulator. The current will not change instantaneously, but it is not difficult to change the inductance through. Changes can only be continuous, usually relatively slow.
