How Via Transitions Ruin Impedance Control PCB and How to Fix Them
In high-speed PCB design, via transitions ruin impedance control by introducing capacitance and inductance that create signal reflections. This pillar page explains the physics, real-world impacts, and proven fixes for maintaining consistent 50Ω impedance through via structures. The Physics of How Via Transitions Ruin Impedance Control PCB Capacitive and Inductive Nature of Vias A via…
