WebNov 17, 2024 · Let’s look closely at these two situations and how the structure of a via/pad + antipad can lead to signal integrity problems. Antipads on vias are precisely sized to hit a target impedance at high frequencies. For Dk = 3 to about Dk = 4, the frequency range where controlled impedance will be needed is slightly above about 3-5 GHz (see the ...
