Abstract

A base tape includes a tape main body including a pair of main surfaces opposed to each other and extending in a length direction with a longitudinal direction of the base tape being defined as the length direction and a direction of a short side being defined as a width direction, the tape main body including a plurality of component accommodation portions located at a predetermined distance from each other in the length direction, each of the plurality of component accommodation portions defining and functioning as an accommodation area of an electronic component.

First claim

What is claimed is:

1. A base tape that accommodates a plurality of electronic components, the base tape comprising:
a tape main body including a pair of main surfaces opposed to each other and extending in a length direction, with a longitudinal direction of the base tape being defined as the length direction and a direction of a short side being defined as a width direction, the tape main body including a plurality of component accommodation portions at a predetermined distance from each other in the length direction, each of the plurality of component accommodation portions defining and functioning as an accommodation area of the plurality of electronic components; wherein
each of the component accommodation portions includes:
an accommodation recess including a rectangular or substantially rectangular opening in one main surface of the tape main body;
a first inclined portion located on a first side of opposed sides in the width direction, of four sides of the opening, the first inclined portion extending from the one main surface toward inside of the accommodation recess to become smaller in height than a second side of the opposed sides in the width direction; and
a second inclined portion located on a first side of opposed sides in the length direction, the second inclined portion extending from the one main surface toward the inside of the accommodation recess to become smaller in height than a second side of the opposed sides in the length direction; and

a magnitude of a gradient θ 1 of the first inclined portion is smaller than a magnitude of a gradient θ 2 of the second inclined portion.

2. The base tape according to claim 1 , wherein the second inclined portion is provided on a side of a forward feed direction of the base tape, in the length direction of the accommodation recess.

3. The base tape according to claim 1 , wherein a condition of 2×D 1 ≤D and 2×D 2 ≤D is satisfied, where a direction orthogonal or substantially orthogonal to the length direction and the width direction is defined as a height direction, and D represents a depth of the accommodation recess in the height direction, D 1 represents a depth of the first inclined portion in the height direction, and D 2 represents a depth of the second inclined portion in the height direction.

4. The base tape according to claim 3 , wherein a condition of D 1 ≤D 2 is satisfied.

5. The base tape according to claim 1 , wherein the first inclined portion and the second inclined portion are each in a shape of a curved surface.

6. A series of electronic components comprising:
the base tape according to claim 1 ;
an electronic component of the plurality of electronic components located in the accommodation recess; and
a cover tape that covers a portion of the one main surface of the tape main body to close the opening in the accommodation recess where the electronic component is located.

7. The series of electronic components according to claim 6 , wherein a condition of W≤T and T≤L is satisfied, where a dimension of the electronic component in the length direction is defined as a W dimension, a dimension of the electronic component in the width direction is defined as an L dimension, and a dimension of the electronic component in a height direction is defined as a T dimension.

8. The series of electronic components according to claim 6 , wherein the electronic component is a multilayer ceramic capacitor.

9. The base tape according to claim 1 , wherein each of the magnitude of the gradient θ 1 of the first inclined portion and the magnitude of the gradient θ 2 of the second inclined portion is between about five degrees and about seventy degrees.

10. The series of electronic components according to claim 7 , wherein the L dimension is between about 0.2 mm and about 1.6 mm.

11. The base tape according to claim 1 , wherein the tape main body has a thickness less than about 1.1 mm.

12. The base tape according to claim 1 , wherein the tape main body has a thickness between about 0.2 mm and about 0.3 mm.

13. The series of electronic components according to claim 6 , wherein
the base tape further includes a plurality of feed holes located at a predetermined distance from each other in the length direction; and
the cover tape does not cover at least one of the plurality of feed holes.

14. The series of electronic components according to claim 6 , wherein the cover tape is transparent or semitransparent.

15. The base tape according to claim 1 , wherein the tape main body has a multilayered structure including at least three layers.

16. The base tape according to claim 1 , wherein the tape main body is made of a multi-layered cardboard.

17. The base tape according to claim 5 , wherein a condition of 2×R 1 ≤D and 2×R 2 ≤D is satisfied, where a direction orthogonal or substantially orthogonal to the length direction and the width direction is defined as a height direction, and D represents a depth of the accommodation recess in the height direction, R 1 represents a radius of curvature of the first inclined surface, and R 2 represents a radius of curvature of the second inclined surface.
