PK-HTE-LP3


▲ Hoz matte side
PK-HTE-LP3 is matte side treated E.D. copper foil, characterized by high temperature elongation property. By precisely controlling the plating, the copper nodule can be well controlled in size and distribution. That can offer proper roughness and adequate bonding to prepregs.

*The Foz foil in developing.
**The peel is tested by building up foil to 18μm.

Note：
  • 1)Roughness is determined by contact stylus profilometer(JIS94).
  • 2)Peel is evaluated by using 4 pieces of normal FR4 prepregs(7628, Tg 140℃, RC43%)
