CARRIER-TAPE FABRICATION DIE AND CARRIER-TAPE FABRICATION METHOD

摘要

A die for fabricating a carrier tape such that the carrier tape is provided with a plurality of housing holes for housing electronic components therein in a state where the housing holes are arranged in a longitudinal direction and penetrates the carrier tape in a thickness direction. The die is less prone to be damaged and is less prone to induce breakages in the interval portions between the housing holes in the carrier tape. A male die includes housing-hole formation convex portions which are constituted by a plurality of first housing-hole formation convex portions having respective tip ends at a relatively-higher heightwise position, and a plurality of second housing-hole formation convex portions having respective tip ends at a relatively-lower heightwise position.

1. A carrier-tape fabrication die for use in fabricating a carrier tape from a tape material, the carrier tape being provided with a plurality of housing holes for housing an electronic component therein in a state where the housing holes are arranged in a longitudinal direction and penetrates the carrier tape in a thickness direction, the carrier-tape fabrication die comprising:
a male die and a female die which are provided such that the male die and the female die are brought together and separated from each other; the male die having a plurality of housing-hole formation convex portions arranged therein corresponding to the plurality of the housing holes to be formed, and the female die having a plurality of housing-hole formation concave portions arranged to receive the respective housing-hole formation convex portions, the housing-hole formation convex portions being adapted to be fitted into the housing-hole formation concave portions while punching a portion of the tape material, thereby forming the housing holes in the tape material, when the male die and the female die are brought into engagement with each other with the tape material sandwiched therebetween, the plurality of housing-hole formation convex portions including a plurality of first housing-hole formation convex portions having a tip end at a relatively-higher heightwise position, and a plurality of second housing-hole formation convex portions having a tip end at a relatively-lower heightwise position, and the plurality of housing-hole formation convex portions being arranged such that at least one of the second housing-hole formation convex portions is positioned between the two first housing-hole formation convex portions and the two first housing-hole formation convex portions being spaced from each other.
