How Trace Width Copper Thickness and Dielectric Height Affect Impedance Control PCB
In high-speed PCB design, impedance control PCB performance depends on three core parameters: trace width (W), copper thickness (T), and dielectric height (H). These factors directly govern characteristic impedance, signal integrity, and manufacturing yield. Understanding their interplay is essential for achieving tight tolerances (±5% or ±10%) and reliable data transmission. 1. How Trace Width (W)…
