Understanding Impedance Control in PCB Design

Impedance control ensures stable electrical resistance in PCB traces, critical for high-speed circuits.

What is Impedance Control in PCBs?

• Maintains signal integrity and reduces distortion.
• Essential for high-frequency applications like 5G and RF devices.

Factors Affecting PCB Impedance

• Trace width, thickness, and dielectric constant.
• Layer stack-up and copper thickness.

Importance of Impedance Control

Impedance control minimizes electromagnetic interference (EMI) and ensures reliable circuit performance in advanced electronics.

By implementing impedance control, designers enhance PCB quality and stability.
