Abstract
PURPOSE: To obtain an excellent cut surface and prevent peeling of the resin layers of a printed-wiring board by a method wherein a maximum of the pressures not destroying the resin in the vicinity of the cut position is set and applied from both upper and lower sides of the printed-wiring board when it is cut by using a cutter.
CONSTITUTION: The printed-wiring board 1 is held being pressed by a pressing apparatus 2 from both upper and lower sides in the directions of arrows C. On doing this, both the upper and lower surfaces are so strongly passed that pressure contact part 3 more or less out into resin layers 4 of the printed-wiring board 1. Said pressure is set so as to be a maximum of the pressures not destroying the resin in the vicinity of the cut position. The board 1 is cut by means of a pair of cutters 6 vertically facing to each other. There is no possibility that the resin layers 4 of the board 1 are peeled off, because they are strongly pressed against a metal substrate 5 along the cutting line.
