Abstract

This invention provides a punching process method of a flexible printed circuit board (PCB), it forms a slit opening section through the flexible PCB. The board shreds do not coil from surface of the bottom mold, it comes out from the conical section of the bottom mold in order. Even though the stroke of a punching head of a metal mold cannot go through the punching hole of a bottom mold, it attains conical section protrusion position. At the approximate central location of a side edge section 22, it builds a punching head 12a for punching hole of a bottom mold 12. A protruded through section 21 is continuously installed along the length direction of the linear slit opening section 20. Since the vertically protruded section with length L and the side edge section of the slit opening section, therefore, the protruded through section 21 generates friction force between the bottom mold 12 and the board shreds 15. Eventually, it prevents board shreds from coiling on surface of the bottom mold.
