Design Guide for Heavy Copper PCB

 

Typical conductor width/spacing/thickness tolerance is +/-20%, although tighter tolerance is achievable.

 

The minimum width and thickness of a heavy copper PCB conductor is determined primarily on the basis of the current carrying capacity required and the maximum permissible conductor temperature rise.

 

A circuit board trace, depending on its size and manufacturing process, may not be rectangular in shape. Heavy copper conductors can significantly add to the overall board thickness.

 

Additive (plating) processed are preferred to subtractive (etching) processes but are more expensive).

 

 

 

Heavy Copper PCB General Info

 

Heavy Copper Board does not have a set of definition per IPC. According to PCB industry, however, peopel generally use this name to identify a printed circuit board with copper conductors 3 oz/ft2 - 10 oz/ft2 in inner and/or outer layers. And Extreme heavy copper PCB refers to 20 oz/ft2 to 200 oz/ft2 printed circuit board

 

Heavy copper normally used for a various products but not limited to: high power distribution, heat dissipation, planar transformers, power convertors, and so on
