Many engineers only discover this late in a project, when signal loss and noise interference trace back to an ill-chosen board material. This article walks through real cases to explore why ordinary circuit boards become performance limiters at high frequencies, and how to avoid common traps through smarter material selection, layout discipline, and manufacturing awareness.
