Top Industrial Applications for Heavy Gauge Copper PCB Solutions
In industries where reliability under extreme conditions is non-negotiable, heavy gauge copper PCB solutions have emerged as a cornerstone technology. Heavy Copper PCBAs (Printed Circuit Board Assemblies) leverage thicker copper layers—often exceeding 3 oz per square foot—to deliver unparalleled current-carrying capacity, thermal resilience, and mechanical stability. These attributes make them indispensable in applications that demand high-power handling, prolonged operational lifetimes, and resistance to thermal fatigue. From renewable energy infrastructures to aerospace systems, heavy copper boards bridge the gap between conventional PCB limitations and the rigorous demands of modern industrial innovation.

Power Electronics and Energy Systems
