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. 

copper_line-spaceHere you will find information on the materials and specialized methods used by Saturn Electronics as well as the latest articles, calculators and DFM rules. Our goal is to provide Heavy Copper PCB Designers and Users with the most advanced, up-to-date information--with an emphasis on the advanced techniques utilized during the Etching and Plating processes.

Why heavy copper Important criteria
1.  Higher voltages 1.  Length
2.  Impedance control 2.  Width
3.  Resistance 3.  Thickness

High-Voltage PCBs
We will also provide information pertaining to Power Electronics and the application of heavy copper PCBs for high voltages and currents.
