PCB Copper Weight: Why It Controls Performance More Than Layout
Why do two seemingly identical PCBs perform so differently under stress? The answer lies beneath the surface: copper weight. This critical specification dictates your board’s current-carrying capacity, thermal management, and overall reliability. In this guide, we break down how to select the ideal copper thickness to prevent overheating and voltage drops without blowing your manufacturing budget. Whether you’re designing for automotive electronics or high-power industrial systems, learn how to optimize your copper weight for peak performance.
