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:
- Busbar
- Connections (see also our sculptured jumpers)
