Heavy Copper PCB

Even there is no actual definition for heavy copper in IPC, however, the industry generally accept that pcbs with 3OZ or
more copper thickness in inner/outer layers are heavy copper pcb.
 
Generally, heavy copper are used in, but not limited to, high power distribution, heat dissipation, planar transformers, and
power convertors
