PCB Trace Spacing Optimization: Why Impedance Fluctuation Outweighs Crosstalk in High-Speed Design (Prevention Strategies)
In PCB design, engineers often remain vigilant about signal integrity in high-speed circuits but tend to overlook impedance control for low-speed traces. When adjacent trace spacing exhibits irregular variations, even for non-high-speed signals, unexpected signal quality issues may arise. The impedance perturbations caused by spacing variations pose a greater threat than crosstalk and deserve …
