PCB Layout Techniques to Optimize Power Module Performance

Starting from the layout of the power supply PCB board?, this paper introduces the PCB layout methods, examples and techniques to optimize the performance of the power supply module.

Analysis and Suppression Method of Ground Wire Interference in PCB Board Wiring

The solution to the common impedance coupling is to reduce the impedance of the common ground wire, or use a single-point ground connection in parallel to completely eliminate the common impedance on PCB board?.
