Printed Circuit Board High Copper Weight
High-power PCB applications need more intensive heat management to cope with high currents and this is possible only through a heavy copper PCB. The copper thickness of traditional PCBs ranges between 1oz. and 3oz. whereas, the thickness of heavy copper goes from 4 oz to 10 oz. There is also another category of a heavy copper PCB known as a super-copper PCB which is 20oz to 200oz per square foot. Such a PCB is suitable for applications that need a high amount of current and high-power thermal or heat management. Heat dissipation in a large PCB becomes easier due to thick copper. ...
