Product Detail

Product Tags

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.
