The fine pattern with the thinness of the thinnest 6 µm is possible, and the high strength foil makes the handling performance excellent.

Feature

  • Since it is a high strength foil even with the thinness of 6 µm, its handling performance is excellent.
  • The fine pattern is available by the VLP level of the roughening treatment and the thinness of 6μm.

Typical application

  • Package substrate
  • High-density multi-layer circuit board
