How to reduce ground bounce in PCB
ByGrace November 23, 2024November 21, 2024
What is ground bounce in PCBA? All ground points on a circuit board assembly should be at the same potential. For some reason, the voltage at the ground reference point of a single board can fluctuate. This phenomenon is called ground bounce. Ideally, for an IC package mounted on a board: How to properly ground…
