Abstract

An electronic component conveying tape includes an elongated carrier tape including recessed storage portions at regular intervals in a length direction, and each storing an electronic component, and an elongated cover tape attached to one surface in a thickness direction of the carrier tape to cover openings of the storage portions. The carrier tape is made of paper, and fibers included in the carrier tape are sloped toward the thickness direction relative to the length direction.

First claim

What is claimed is:

1. An electronic component conveying tape comprising:
an elongated carrier tape including a plurality of recessed storage portions at regular intervals in a length direction, and each storing an electronic component; and
an elongated cover tape attached to one surface in a thickness direction of the carrier tape to cover openings of the plurality of storage portions; wherein
the carrier tape is made of paper, and fibers included in the carrier tape are sloped toward the thickness direction relative to the length direction.

2. The electronic component conveying tape according to claim 1 , wherein, in a plan view seen from a plane passing through the thickness direction and the length direction, at least about 70% of all of the fibers are fibers having a thickness direction orientation degree of about 20° to about 70°, which is a slope towards the thickness direction relative to the length direction.

3. The electronic component conveying tape according to claim 1 , wherein, in a plan view seen from a plane passing through the length direction and the thickness direction, an average of a thickness direction orientation degree, which is a slope toward the thickness direction relative to the length direction, for all of the fibers is about 0° to about 45°.

4. The electronic component conveying tape according to claim 1 , wherein, in a plan view seen from a plane passing through the length direction and a width direction, at least about 70% of all of the fibers are fibers having a width direction orientation degree of about −60° to about 60°, which is a slope toward the width direction relative to the length direction.

5. The electronic component conveying tape according to claim 1 , wherein in a plan view seen from a plane passing through the length direction and the width direction, an average of a width direction orientation degree, which is a slope toward the width direction relative to the length direction, for all of the fibers is about −45° to about 45°.

6. The electronic component conveying tape according to claim 1 , wherein dimensions of the storage portions are each about 0.665±0.03 mm in the length direction, about 0.335±0.03 mm in the width direction, and about 0.335±0.03 mm in a depth direction.

7. The electronic component conveying tape according to claim 1 , wherein each of the plurality of recessed storage portions has a rectangular or substantially rectangular shape in a plan view of the carrier tape.

8. The electronic component conveying tape according to claim 1 , wherein the carrier tape includes feed holes in a line at regular intervals in the length direction.

9. The electronic component conveying tape according to claim 8 , wherein each of the feed holes has a circular or substantially circular shape in in a plan view of the carrier tape.

10. The electronic component conveying tape according to claim 1 , wherein the cover tape is made of a transparent resin.

11. An electronic component conveying reel comprising:
a core material; and
the electronic component conveying tape according to claim 1 wound around the core material; wherein
the fibers provided in a vicinity of the cover tape in the thickness direction is sloped toward a side opposite to a side on which the electronic component conveying tape in the length direction is fed.

12. The electronic component conveying reel according to claim 11 , wherein, in a plan view seen from a plane passing through the thickness direction and the length direction, at least about 70% of all of the fibers are fibers having a thickness direction orientation degree of about 20° to about 70°, which is a slope towards the thickness direction relative to the length direction.

13. The electronic component conveying reel according to claim 11 , wherein, in a plan view seen from a plane passing through the length direction and the thickness direction, an average of a thickness direction orientation degree, which is a slope toward the thickness direction relative to the length direction, for all of the fibers is about 0° to about 45°.

14. The electronic component conveying reel according to claim 11 , wherein, in a plan view seen from a plane passing through the length direction and a width direction, at least about 70% of all of the fibers are fibers having a width direction orientation degree of about −60° to about 60°, which is a slope toward the width direction relative to the length direction.

15. The electronic component conveying reel according to claim 11 , wherein in a plan view seen from a plane passing through the length direction and the width direction, an average of a width direction orientation degree, which is a slope toward the width direction relative to the length direction, for all of the fibers is about −45° to about 45°.

16. The electronic component conveying reel according to claim 11 , wherein dimensions of the storage portions are each about 0.665±0.03 mm in the length direction, about 0.335±0.03 mm in the width direction, and about 0.335±0.03 mm in a depth direction.

17. The electronic component conveying reel according to claim 11 , wherein each of the plurality of recessed storage portions has a rectangular or substantially rectangular shape in a plan view of the carrier tape.

18. The electronic component conveying reel according to claim 11 , wherein the carrier tape includes feed holes in a line at regular intervals in the length direction.

19. The electronic component conveying reel according to claim 18 , wherein each of the feed holes has a circular or substantially circular shape in in a plan view of the carrier tape.

20. The electronic component conveying reel according to claim 11 , wherein the cover tape is made of a transparent resin.
