Thick copper PCB

Available in different thicknesses of copper (up to 500 µm), differential copper PCBs can meet your most specific needs for various mechanical and electrical characteristics. Using a differential etching process, we can reduce the thickness of conductors in areas that must be flexible while maintaining the full original thickness of the copper for high-power conductors and terminals. An insulating film is then applied to each surface. The copper remains accessible on both faces in the selected areas.


We offer the following surface finishes:

  • Immersion silver
  • Immersion tin
  • Electrolytic tin
  • Electrolytic tin/lead
  • Remelted tin
  • HAL
  • Immersion nickel/gold
  • Electrolytic nickel/gold

Differential copper PCBs can be used for applications such as:
