METHOD OF MANUFACTURING FLEXIBLE PRINTED CIRCUIT SHEETS Abstract of the Disclosure The present invention relates to a method of manufacturing a flexible printed circuit sheet for use in electrical and electronic equipment. The method comprises the steps of providing rows of guide holes at predeter- mined intervals along opposite edges in the longitudinal direction of a flexible base sheet of belt-like configur- ation prepared by applying electrically conductive foil onto at least one entire surface of a flexible base material. Electrically conductive circuit patterns are formed, defined by frames formed by leaving the electric- ally conductive foil at the peripheral portions thereof and provided at predetermined intervals in the longitudinal direction between the rows of the guide holes along the opposite edges. The flexible base sheet is moved and positioned through engagement of the guide holes with a drive unit for selectively forming part or all of an electronic circuit by attaching electronic parts for connection to the electronic circuit patterns.
