Guidelines for grounding a PCB board and the different types, methods, and rules involved. Grounding is essential for correct functionality and safety in a printed circuit board. Understanding power ground, signal ground, virtual ground, surge and lightning protection ground, and other methods is crucial for successful PCB grounding. Following grounding rules such as leaving nothing unattached, providing a common ground point, minimizing series vias, and planning for dynamic variance between grounds is important for a successful grounding activity.
