Why Controlled Impedance Really Matters

January 30, 2018
Every day, PCB designs and components become smaller, faster – in other words, more complicated. It is now crucial to slow certain circuits down in order to allow specific functions of components to perform before others. The time of simple interconnecting traces and conductors is over. What is controlled impedance? Controlled impedance is the characteristic impedance of a transmission line formed by PCB conductors. It is relevant when high-frequency signals propagate on the PCB transmission lines. Controlled impedance is important for signal integrity: it is the propagation..
