METHOD AND DEVICE FOR DIVIDING PRINTED WIRING BOARD

PROBLEM TO BE SOLVED: To provide a printed wiring board dividing method and a device, which split a printed wiring board into separate pieces, causing a less stress to the board when the wiring board is divided, providing the separated pieces a high degree of flexibility, and realizing an in-line alignment single flow. SOLUTION: The separate pieces 61 are linked together with linking bridges 62, the linking bridges 62 of the printed wiring board 60 supported by a sheet frame 63 are cut with a cutter of a nail clipper type having an upper cutting blade 24 and a lower cutting blade 25, whereby the shape of the separate piece 61 is ensured of a high degree of flexibility. The upper and lower blade 24 and 25, are moved up and down by a cam drive system of a lever structure, so that a high power is not necessary for a drive source, and the dividing device can be miniaturized. Furthermore, the dividing device copes flexibly with a cutting position by an NC control, and an in-line alignment single flow can be realized. COPYRIGHT: (C)2003,JPO
