Patent ID: 8069557

Claim:
A method of manufacturing a circuit forming board, comprising: impregnating an elongated reinforcing member with impregnation material, the reinforcing member extending in a first direction; transferring the reinforcing member in a second direction such that the first direction of the reinforcing member is parallel to the second direction, wherein said impregnating of the elongated reinforcing member with impregnation material occurs simultaneously with said transferring of the reinforcing member in the second direction; adhering films directly onto an upper surface and a lower surface, respectively, of the reinforcing member so as to be entirely peelable off of the upper and lower surfaces of the reinforcing member; and transferring the reinforcing member in a third direction orthogonal to the first direction of the reinforcing member, wherein said adhering of the films directly onto the upper surface and the lower surface, respectively, of the reinforcing member occurs simultaneously with said transferring of the reinforcing member in the third direction orthogonal to the first direction of the reinforcing member.
