The construction of a heavy copper circuit endows a board with benefits such as:

• Increased endurance to thermal strains.
• Increased current carrying capacity.
• Increased mechanical strength at connector sites and in PTH holes.
• Use of exotic materials to their full potential (i.e., high temperature) without circuit failure.
• Reduced product size by incorporating multiple copper weights on the same layer of circuitry (see Figure 1).
• Heavy copper plated vias carry higher current through the board and help to transfer heat to an external heatsink.
• On-board heatsinks directly plated onto the board surface using up to 120-oz copper planes.
• On-board high-power-density planar transformers
