Impedance control is required whenever the signal rise time is comparable to, or shorter than, the propagation delay of the PCB trace. In such cases, impedance mismatches along the signal path cause partial signal reflections, which distort the waveform and degrade timing margins.

Typical active components include integrated circuits (ICs), transistors, MOSFETs, diodes, voltage regulators, microcontrollers, and power management devices. While this functional definition is widely accepted, it represents only a surface-level understanding. From an engineering and manufacturing perspective, active components introduce a distinct set of challenges that go far beyond circuit functionality.
