Abstract
This invention relates to a flexible PCB. It discharges the punching dusts from a lower die taper part one after another without flying out the dust on the surface of the lower die. Even though using a die with a stroke so short, a punching- process through punch inserted in the die does not reach a position. It projects to the lower die taper part from its punch hole at the shape work such as removal of blind through-holes or unused portions of a flexible PCB. A flexible PCB 14 has circular lands formed on both sides of an insulation layer 17 with copper foils 16a, 16b. When punching a portion surrounded by the dashed line A, the copper foil of a part 18 inside the dashed line A is previously etched to expose the insulation layer 17. The part of the dashed line A is punched by a punching-through punch to make the inside portion 18 of the punching dust easy to bend, as this portion is of only the insulation layer 17. Moreover, it relaxes the repulsion force of the punching dust and the lower die. Eventually, it prevents the dust from flying out of the lower die.
