Heavy Copper Resource Center

High-Power Heavy Cu Resource Center

Heavy / Thick / Extreme copper printed circuit boards (>2 ounce copper per layer) are not commonly designed or consumed.  Yet, their high current carrying capacity and thermal benefits do lend them to be great fits for certain applications.  Due to their scarcity, though, good information for designers can be hard to find.  We aim to make this resource center a bridge between design and fabrication.  Should there be a topic or question we have not addressed, please contact Jim Kelch and we will do our best to research the topic and add relevant information to this portal.
