WebAug 14, 2024 · The density you need to place stitching vias is related to the frequency content of the signals in your circuit. If the maximum frequency in the circuit is 500 MHz (corresponding to roughly 30 cm wavelength in FR4), then I'd expect that if the stitching vias are spaced no further than 3 cm apart you'll be fine. WebJul 29, 2024 · The two copper lands connect to the bottom ground plane through several stitched vias, effectively turning the track into an external microstrip. Placing a ground plane in the layer above the track and connecting it to the two copper lands and the bottom ground plane through more stitched vias turns the track into an internal microstrip.
