[0003] [Patent Document 1] Japanese Patent Application Publication No. 6-171666 Summary of the Invention [Problem to be solved by the invention]

[0004] In such electronic component packaging bodies, a cylindrical core member fits into a mounter, and when the mounter automatically mounts electronic components, the electronic component packaging tape (electronic component carrier tape) is gradually pulled out as the electronic component packaging body rotates. When the electronic component packaging tape (electronic component carrier tape) is completely pulled out, the core member remains in the mounter. This requires the work of removing the core member, which reduces the workability of automatic electronic component mounting.

[0007] The electronic component packaging tape according to the present invention comprises the above-mentioned electronic component carrier tape, a long cover tape attached to the electronic component carrier tape so as to cover the openings of the plurality of pockets, and the plurality of electronic components housed in each of the plurality of pockets.

[0008] The electronic component packaging body according to the present invention is configured by winding the above-mentioned electronic component packaging tape around the core member as the winding start point. [Effects of the Invention]

DETAILED DESCRIPTION OF THE INVENTION

[0011] An example of an embodiment of the present invention will be described below with reference to the accompanying drawings, in which the same or equivalent parts are designated by the same reference numerals.

[0012] [First embodiment] (Electronic component packaging) Fig. 1 is a side view showing an electronic component packaging body according to a first embodiment. As shown in Fig. 1, the electronic component packaging body 1 is configured by winding an electronic component packaging tape 10 starting from one end T1, i.e., a core member 40. For example, the electronic component packaging tape 10 is wound so that the cover tape side, which will be described later, is on the inner periphery. The electronic component packaging body 1 is also sometimes called a taping reel.

[0013] (Electronic component packaging tape and electronic component carrier tape) Fig. 2 is a plan view showing an electronic component packaging tape and an electronic component carrier tape according to the first embodiment, and Fig. 3 is a cross-sectional view taken along line III-III of the electronic component packaging tape and electronic component carrier tape shown in Fig. 2. As shown in Fig. 2 and Fig. 3, an electronic component packaging tape 10 includes an electronic component carrier tape 20, a cover tape 30, and a plurality of electronic components 100.

[0014] The electronic component carrier tape 20 is a long or strip-shaped member. The electronic component carrier tape 20 has a plurality of pockets 21 formed therein, spaced equally along the length. The pockets 21 are recesses for accommodating electronic components 100 and have openings for removing the electronic components. The electronic component carrier tape 20 also has a plurality of feed holes 22 formed therein, spaced equally along the length. The feed holes 22 are used for transporting electronic components during automatic mounting by a mounter. The material of the electronic component carrier tape 20 is not particularly limited, but resin, paper, or the like can be used. The electronic component carrier tape 20 and the electronic component packaging tape 10 are sometimes referred to as a series of electronic components because the electronic components are connected to each other.

[0015] The cover tape 30 is a long or strip-shaped member. The cover tape 30 is attached to the electronic component carrier tape 20 so as to cover the openings of the multiple pockets 21 and not block the feed holes 22. This seals each electronic component 100 in each pocket 21. The cover tape 30 is attached to the electronic component carrier tape 20 in a releasable manner. The material of the cover tape 30 is not particularly limited, but resin, paper, or the like is used.

[0016] The plurality of electronic components 100 are accommodated in the plurality of pockets 21 of the electronic component carrier tape 20. Examples of the electronic components 100 include various surface-mount electronic components such as multilayer ceramic capacitors using dielectric ceramics, piezoelectric components using piezoelectric ceramics, thermistors using semiconductor ceramics, and inductors using magnetic ceramics.

[0017] (core member) A flat core member 40 is disposed at one longitudinal end T1 of the electronic component carrier tape 20, i.e., at one longitudinal end T1 of the electronic component packaging tape 10. The core member 40 is made of the same material as the electronic component carrier tape 20 and is disposed in a convex shape on the main surface of the electronic component carrier tape 20 facing the cover tape 30. For example, the core member 40 may be formed by superimposing one or more pieces of the electronic component carrier tape 20 on the main surface of the one end T1 of the electronic component carrier tape 20. Alternatively, the core member 40 may be attached by folding one end of the electronic component carrier tape 20 back once or multiple times. The core member 40 may also be disposed in a convex shape on the main surface of the electronic component carrier tape 20 opposite the cover tape 30.

[0018] 10 is a perspective view showing a fitting portion between a cylindrical core member and an electronic component packaging tape (electronic component carrier tape) in a conventional electronic component packaging body. As shown in FIG. 10, the conventional electronic component packaging body 1X is configured such that one end T1 of the electronic component packaging tape 10X (electronic component carrier tape 20X) is simply inserted into a hole 40h of a cylindrical core member 40X, and the electronic component packaging tape 10X (electronic component carrier tape) 20X is wound around the cylindrical core member 40X.

[0019] In such an electronic component packaging body 1X, the cylindrical core member 40X fits into a mounter, and when the mounter automatically mounts electronic components, the electronic component packaging tape 10X (electronic component carrier tape 20X) is gradually pulled out as the electronic component packaging body 1X rotates. When the electronic component packaging tape 10X (electronic component carrier tape 20X) is completely pulled out, the core member 40X remains in the mounter. This requires the work of removing the core member 40X, which reduces the workability of automatic mounting of electronic components.

[0020] In this regard, according to the electronic component carrier tape 20, electronic component packaging tape 10, and electronic component packaging body 1 of the first embodiment, the core member 40 is not cylindrical but flat, and is disposed and fixed at one end T1 of the electronic component carrier tape 20, i.e., the electronic component packaging tape 10. As a result, when electronic components are automatically mounted by a mounter, the core member 40 is pulled out together with the electronic component packaging tape 10 (electronic component carrier tape 20) and does not remain in the mounter. Therefore, there is no need to remove the cylindrical core member as in the conventional case, and the workability of automatic mounting of electronic components can be improved.

[0021] Furthermore, the flat core member 40 can stabilize one end T1 at the start of winding when winding the electronic component packaging tape 10 (electronic component carrier tape 20).

[0022] Furthermore, when the electronic component packaging body 1 is fitted to a mounter, the flat core member 40 functions as a fitting portion. For example, as shown in FIG. 1, the fitting portion of the mounter has a cylindrical shape with three protrusions (indicated by dashed lines). The flat core member 40 can be fitted suitably with the fitting portion of such a mounter. Furthermore, because the core member 40 is convex, it can be fitted suitably with the fitting portion of such a mounter.

[0023] [Second embodiment] (Electronic component packaging) Fig. 4 is a side view showing an electronic component packaging body according to a second embodiment. As shown in Fig. 4, an electronic component packaging body 1A of the second embodiment includes an electronic component packaging tape 10A instead of the electronic component packaging tape 10 in the electronic component packaging body 1 of the first embodiment shown in Fig. 1. The electronic component packaging body 1A is configured by winding the electronic component packaging tape 10A starting from one end T1, i.e., the core member 40A.

[0024] (Electronic component packaging tape and electronic component carrier tape) Fig. 5 is a plan view showing an electronic component packaging tape and an electronic component carrier tape according to a second embodiment, and Fig. 6 is a cross-sectional view taken along line VI-VI of the electronic component packaging tape and electronic component carrier tape shown in Fig. 5. As shown in Figs. 5 and 6, an electronic component packaging tape 10A of the second embodiment includes an electronic component carrier tape 20A instead of the electronic component carrier tape 20 in the electronic component packaging tape 10 of the first embodiment shown in Figs. 2 and 3. The other configurations of the electronic component packaging tape 10A are the same as those of the electronic component packaging tape 10 of the first embodiment.

[0025] (core member) The electronic component carrier tape 20A has a core member 40A instead of the core member 40 in the electronic component carrier tape 20 of the first embodiment. Other configurations of the electronic component carrier tape 20A are the same as those of the electronic component carrier tape 20 of the first embodiment.

[0026] A flat core member 40A is disposed at one longitudinal end T1 of the electronic component carrier tape 20A, i.e., at one longitudinal end T1 of the electronic component packaging tape 10A. The core member 40A is made of an adhesive material and is disposed in a convex shape on the main surface of the electronic component carrier tape 20A facing the cover tape 30. Examples of the adhesive material include an adhesive tape. For example, the core member 40A may be formed by superimposing an adhesive tape on the main surface of the electronic component carrier tape 20A at one end T1. Alternatively, the core member 40A may be disposed in a convex shape on the main surface of the electronic component carrier tape 20A opposite the cover tape 30.

[0027] In the electronic component carrier tape 20A, electronic component packaging tape 10A, and electronic component packaging body 1A of the second embodiment, the core member 40A is not cylindrical but flat, and is disposed and fixed at one end T1 of the electronic component carrier tape 20A, i.e., the electronic component packaging tape 10A. As a result, when electronic components are automatically mounted by a mounter, the core member 40A is pulled out together with the electronic component packaging tape 10A (electronic component carrier tape 20A) and does not remain in the mounter. Therefore, there is no need to remove the cylindrical core member as in the conventional method, and the workability of automatic mounting of electronic components can be improved.

[0028] Furthermore, the flat core member 40A can stabilize one end T1 at the start of winding when winding the electronic component packaging tape 10A (electronic component carrier tape 20A).

[0029] Furthermore, when the electronic component packaging body 1A is fitted to a mounter, the flat core member 40A functions as a fitting portion. For example, as shown in FIG. 4, the fitting portion of the mounter has a cylindrical shape with three protrusions (indicated by dashed lines). The flat core member 40A can be suitably fitted to the fitting portion of such a mounter. Furthermore, since the core member 40A is convex, it can be suitably fitted to the fitting portion of such a mounter. Furthermore, since the core member 40A is made of an adhesive material, it can be suitably adhered to the fitting portion of such a mounter.

[0030] [Third embodiment] (Electronic component packaging) Fig. 7 is a side view showing an electronic component packaging body according to a third embodiment. As shown in Fig. 7, an electronic component packaging body 1B of the third embodiment includes an electronic component packaging tape 10B instead of the electronic component packaging tape 10 in the electronic component packaging body 1 of the first embodiment shown in Fig. 1. The electronic component packaging body 1B is configured by winding the electronic component packaging tape 10B starting from one end T1, i.e., the core member 40B.

[0031] (Electronic component packaging tape and electronic component carrier tape) Fig. 8 is a plan view showing an electronic component packaging tape and an electronic component carrier tape according to a third embodiment, and Fig. 9 is a cross-sectional view taken along line IX-IX of the electronic component packaging tape and the electronic component carrier tape shown in Fig. 8. As shown in Figs. 8 and 9, an electronic component packaging tape 10B of the third embodiment includes an electronic component carrier tape 20B instead of the electronic component carrier tape 20 in the electronic component packaging tape 10 of the first embodiment shown in Figs. 2 and 3. The other configurations of the electronic component packaging tape 10B are the same as those of the electronic component packaging tape 10 of the first embodiment.

[0032] (core member) The electronic component carrier tape 20B has a core member 40B instead of the core member 40 in the electronic component carrier tape 20 of the first embodiment. Other configurations of the electronic component carrier tape 20B are the same as those of the electronic component carrier tape 20 of the first embodiment.

[0033] A flat core member 40B is disposed at one longitudinal end T1 of the electronic component carrier tape 20B, i.e., at one longitudinal end T1 of the electronic component packaging tape 10B. The core member 40B is made of a curing agent. Examples of the curing agent include a thermosetting resin such as an epoxy resin, and a photocuring resin. For example, the core member 40B may be formed by impregnating the one longitudinal end T1 of the electronic component carrier tape 20B with a curing agent.

[0034] In the electronic component carrier tape 20B, electronic component packaging tape 10B, and electronic component packaging body 1B of the third embodiment, the core member 40B is not cylindrical but flat, and is disposed and fixed at one end T1 of the electronic component carrier tape 20B, i.e., the electronic component packaging tape 10B. As a result, when electronic components are automatically mounted by a mounter, the core member 40B is pulled out together with the electronic component packaging tape 10B (electronic component carrier tape 20B) and does not remain in the mounter. Therefore, there is no need to remove the cylindrical core member as in the conventional case, and the workability of automatic mounting of electronic components can be improved.

[0035] Furthermore, the flat core member 40B can stabilize one end T1 at the start of winding when winding the electronic component packaging tape 10A (electronic component carrier tape 20A).

[0036] Furthermore, when the electronic component packaging body 1B is fitted to a mounter, the flat core member 40B functions as a fitting portion. For example, as shown in Fig. 7, the fitting portion of the mounter has three cylindrical protrusions (indicated by dashed lines). The flat core member 40B can be fitted suitably to the fitting portion of such a mounter.

[0037] Although the present invention has been described above with reference to the preferred embodiment, it is not limited to the preferred embodiment and various modifications and variations are possible. For example, the preferred embodiments may be combined. For example, the core members 40, 40A, and 40B may contain two or more of the same material, adhesive, and hardener as the electronic component carrier tape. [Explanation of symbols]
