Good PCB grounding is critical for signal integrity and EMI control.
Ground Plane Best Practices:
1. Use a continuous ground plane on at least one layer.
2. Place ground vias frequently along high-speed return paths.
3. Connect analog and digital ground at a single point.
4. Avoid cutting slots in the ground plane.
5. Use stitching vias around board edges.
6. Decoupling capacitors need short ground return paths.
Common Mistakes: ground plane splits, too few vias, ground loops.
A clean ground plane is the foundation of reliable PCB design.
