Impedance control PCB design is not simply about connecting wires; it's about ensuring that the signal source and load communicate in the same language. When the characteristic impedance is mismatched, the signal will reflect between the traces, causing waveform distortion and energy loss. This article shares how to move beyond DC circuit thinking, understand the relationship between impedance and trace geometry, dielectric materials, and the impact of layer stack-up planning..."}
