Single-point grounding and multi-point grounding are two methods of establishing reference points in PCB design, where single-point grounding is used in low-frequency circuits for minimal wiring interaction, while multi-point grounding is preferred in high-frequency circuits to reduce parasitic effects.

This article compares PCB single-point and multi-point grounding methods, highlighting that single-point grounding is used for low frequencies to prevent common ground impedance issues, multi-point grounding is for high frequencies to reduce electromagnetic interference, and mixed grounding applies for intermediate frequencies based on the signal wavelength.
