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 without circuit failure.
- Reduced product size by incorporating multiple copper weights on the same layer of circuitry .
- Heavy copper plated vias carry higher current through the board and help to transfer heat to an external heatsink.
