Flexible Printed Circuits (FPC)

Flexible printed circuits (FPC) are stamped from strip with a maximum thickness of 105 µm. The strip can either be made by electrodeposition (ED) or - as done at Wieland - by rolling and annealing (RA). Compared to electrodeposition, rolling and annealing operations have the advantage that the mechanical properties, such as

  • strength
  • resilience and relaxation
  • grain size

can be adjusted.


The dry and high-quality surfaces of rolled products facilitate subsequent laminating operations. The Wieland alloy K14 (Cu-PHC) is particularly suitable.

If you have any questions regarding temper and strip thickness, please contact us at .
