Abstract
A circuit board-use member has a reinforcing plate, a removable organic layer, a flexible film having a circuit pattern, and a peeling-assist layer laminated in that order; a method forms a circuit board by forming a circuit pattern on a flexible film which is adhered to a reinforcing plate with a removable organic layer interposed therebetween, and peeling the film from the plate at an angle ranging from more than 0° to 80°; and an apparatus for forming a circuit board has one of a separation means for separating the flexible film from the reinforcing plate while the film contacts a curved support body; a curved separation means for separating the reinforcing plate from a support body for the flexible film while the plate is curved; or a moving means for relatively moving holding means and peeling means having a wedge-shaped member for peeling the flexible film.

4. A method for forming a circuit board comprising the step of:
- peeling a flexible film from a circuit board-use member which comprises the flexible film having a circuit pattern formed on one surface thereof, and a reinforcing plate adhered to the opposite surface of the flexible film to said one surface with a removable organic layer interposed therebetween, wherein the flexible film is peeled away from the reinforcing plate while a peel angle is being maintained in the range of more than 0°
to 80°

14. An apparatus for forming a circuit board by peeling a flexible film from a flexible film substrate comprising a reinforcing plate and the flexible film which is provided with a circuit pattern and which is adhered to the reinforcing plate, the apparatus comprising one of the following means:
-
i) means for separating the flexible film from the reinforcing plate while the flexible film is being in contact with a curved support body;
ii) means for separating the reinforcing plate from a support body for the flexible film while the reinforcing plate is being curved; and
iii) means for relatively moving a support body and peeling means, the support body supporting a circuit board-use member, the peeling means having a wedge-shaped peeling member for peeling the flexible film. - View Dependent Claims (15, 16, 17, 18, 19, 20, 22)
