Method of manufacturing electronic circuit apparatus

Claim 1

A method of manufacturing a flexible printed circuit sheet for use in electrical and electronic equipment, which comprises the steps of: providing a flexible base sheet having a belt-like configuration and a flexible base material with a layer of electrically conductive material covering the entire surface of at least one side of said flexible base material and having rows of guide holes at predetermined intervals along the opposite longitudinal edges of said base sheet; forming electrically conductive circuit patterns on said base sheet at predetermined intervals in the longitudinal direction and at positions between the rows of said guide holes by removing electrically conductive material from said base sheet for leaving circuit elements constituting said circuit pattrns, said circuit patterns each occupying an area on said base sheet which has a periphery and including peripheral edge circuit elements extending along at least substantially the entire periphery of each area occupied by the respective circuit patterns and leaving electrically conductive material around the respective areas with the conductive material edge thereof spaced outwardly from the periphery of the respective areas, the electrically conductive material which is left on said base sheet extending to the base sheet edges and around said guide holes; moving said flexible base sheet and positioning the circuit patterns successively at a parts attaching position by engagement of moving and positioning means in said guide holes and connecting electronic parts to the individual successive circuit patterns as the circuit patterns are successively positioned at said parts attaching position; and thereafter moving said base sheet for positioning successive circuit patterns in a cutting position and cutting individual flexible printed circuit sheets from said base sheet by cutting through said flexible base sheet on a line along and adjacent the edges of said peripheral edge circuit elements between said peripheral edge circuit elements and the conductive material edge left around the areas for separating the portions of said base sheet having said circuit patterns thereon from the remainder of said base sheet.
