    Abstract: PROBLEM TO BE SOLVED: To provide a method for manufacturing a flexible printed circuit board capable of arranging circuit lines with a high density by forming the cross sectional shape of the circuit in a shape close to a rectangular shape from a trapezoidal shape.
    SOLUTION: A laminate sticking an aluminum foil and a film made of a synthetic resin is prepared. The surface of the aluminum foil in the laminate is resist-treated, and a resist and a non-resist are formed and etched. A non-resist site is post-treated by a ferric-chloride aqueous solution after etching. Then, the non-resist site is finish-treated by an aqueous solution selected from a group consisting of a sodium-hydroxide aqueous solution, a sodium-carbonate aqueous solution, a sodium-phosphate aqueous solution, a phosphoric-acid aqueous solution, a nitric-acid aqueous solution, and a chromic-acid aqueous solution. The flexible printed circuit board thus obtained is used as an antenna coil for an IC tag and an IC chip.

    Abstract: PROBLEM TO BE SOLVED: To provide a method for making a rim edge of a circuit line sharp, in a process of manufacturing a printed circuit board through printing a resist ink with a gravure printing technique.
    SOLUTION: A laminated body is prepared by laminating a synthetic resin film with an aluminum foil. Further, the resist ink is prepared by dissolving a resin into an organic solvent and blending fine powders of silica in the solution. A predetermined pattern is printed on the surface of the aluminum foil of the laminated body by using the resist ink with the gravure printing technique to form a resist part in which the resin film is stuck on the surface of the aluminum foil and a non-resist part on which the resin film is not stuck on the surface of the aluminum foil. Then, the aluminum foil exposed in the non-resist part is removed by etching. Further subsequently, the resin film remaining in the resist part is removed. Thus obtained printed circuit board shows a sharp rim edge of the circuit line due to the action of the fine powders of silica.
