pcb design mistakes

Copper Thickness, Dielectric Loss, and Power Integrity What’s the Connection?

Every PCB designer has faced that frustrating moment: the simulation looks flawless, but the real board doesn’t behave as expected. Maybe the voltage dips under load, noise creeps into sensitive circuits, or thermal hotspots appear out of nowhere. Often, the root cause isn’t obvious. It’s hidden in the materials themselves — the copper that carries
