Impedance Control PCB

Impedance Control PCB 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. PCB Impedance Control is important for signal integrity: it is the propagation of signals without distortion.


Impedance control is matching PCB trace dimensions and locations with the properties of the substrate material to make sure that the strength of a signal traveling along a trace is within a required range. So Controlled impedance in the fabrication and design of PCB is a complex and broad topic.

product structure

Impedance Control PCB strictly control the trace width, thickness and dielectric thickness, PCB circuit tolerance of impedance trace ≤±5% is better for impedance matching. Application in High-frequency, high-speed devices and 5G communication equipment, etc.
