Abstract

Provided is a carrier tape with improved tensile strength and flexural rigidity in a longitudinal direction of a base material, including recesses that can be provided at a narrow pitch in a first surface of the base material, and manufacturable at reduced cost, as well as to provide an apparatus and a method for manufacturing such a carrier tape. A carrier tape of the present invention is constituted by a strip-shaped base material, and includes a plurality of recesses provided in a first surface of the base material and for containing electronic components, a covering unit configured to seal openings of the recesses, and a projection provided on a second surface of the base material along a longitudinal direction of the base material. A length of the projection extends over at least two of the recesses.

First claim

What is claimed is:

1. A carrier tape constituted by a strip-shaped base material, the tape comprising:
a plurality of recesses provided in a first surface of the base material and for respectively containing electronic components;
a covering unit configured to seal openings of the recesses; and
a projection provided on a second surface of the base material along a longitudinal direction of the base material, a length of the projection being such that the projection extends over at least two of the recesses, the projection being provided at a position immediately under the recesses, wherein
the first surface, the second surface and the projection are one piece and being the same material and the plurality of recesses and the projection are formed by a punch.

2. The carrier tape according to claim 1 , wherein
in a direction perpendicular to the longitudinal direction of the base material, a width of the projection is greater than that of the recesses.

3. The carrier tape according to claim 2 , wherein
a depth of the recesses is such that each recess reaches down to a position of the projection provided on the second surface of the base material.

4. The carrier tape according to claim 2 , wherein
the base material is made of paper.

5. The carrier tape according to claim 1 , wherein
the base material is made of paper.

6. A carrier tape constituted by a strip-shaped base material, the tape comprising:
a plurality of recesses provided in a first surface of the base material and for respectively containing electronic components;
a covering unit configured to seal openings of the recesses; and
a projection formed of at least a portion of a second surface of the base material along a longitudinal direction of the base material, the projection being formed at a position immediately under the recesses, wherein
the projection is provided from a first end of the base material along an entire length of the base material in the longitudinal direction to a second end of the base material.

7. The carrier tape according to claim 6 , wherein
in a direction perpendicular to the longitudinal direction of the base material, a width of the projection is greater than that of the recesses.

8. The carrier tape according to claim 7 , wherein
a depth of the recesses is such that each recess reaches down to a position of the projection provided on the second surface of the base material.

9. The carrier tape according to claim 7 , wherein
the base material is made of paper.

10. The carrier tape according to claim 6 , wherein
the base material is made of paper.
