  • Patent number: 6362433
    Abstract: A flexible printed circuit board that is intended to minimize curling is formed having a first polyimide-resin layer with a conductor pattern formed on one surface thereof and supporting that conductor pattern. A second polyimide-resin is formed on another surface of the conductor pattern and covers and protects the circuit of the conductor pattern. The polyimide-resin layers are chosen so that a difference between a coefficient of linear thermal expansion of the first polyimide-resin layer and the coefficient of linear thermal expansion of the second polyimide-resin layer is 3×10−6/K or smaller.

  • Patent number: 6233821
    Abstract: The present invention aims to obtain a flexible printed wiring board with good flatness. According to the present invention, a copper-clad film 3 is formed by applying a polyamic acid solution on one surface of a copper foil 2 and thermally contracting the polyamic acid layer la so that the other surface of the copper foil 2 may form a convex surface of a curling surface to form a polyimide film 1. A polyamic acid solution is applied on the other surface of the copper foil 2 of the copper-clad film 3, and then the polyamic acid layer 5a is thermally contracted to form a protective film 5, whereby a flexible printed wiring board 10 is obtained.
