WebIn general terms, a via connects one PCB layer to another. Vias may join traces, pads and other conductive elements on a PCB through a copper cylinder placed inside holes. These holes pass through the affected layers on the board. PCB Vias need a certain volume of copper on a layer to ensure that the layers are really connected. Web20 de set. de 2024 · If the signal in the trace is, say, 5GHz, and the cavity's resonances are 3 and 9GHz (give or take, plus other modes), then adding some vias in certain locations could raise the resonance to 5GHz, causing a null in that trace's response. So, that said, there may be cases where a dubious design gets worse from more via stitching.
