Carrier reel, carriage method using the carrier reel, and method for manufacturing electronic device

Abstract: A carrier reel according to the present invention is constituted by a flange portion having a first surface and a second surface which is opposed to and substantially parallel to the first surface, and a hub portion which is provided between the first surface and the second surface and to which the flange portion is connected. A bearing portion at which a shaft used for taking out each electronic component after carriage is supported is provide to the hub portion, and spaces for accommodating therein a drying agent, i.e., drying agent accommodating portions are formed at the part of the hub portion except the bearing portion. The drying agent is accommodated in the drying agent accommodating portions. The carrier reel having the drying agent accommodated therein is put in a damp proof bag to be sealed. The sealed damp proof bag is then packaged to be carried. As a result, it is possible to provide the carrier reel by which the cubic volume of the entire package becomes constant irrespective of characteristics of electronic components to be carried and provide a carriage method using such a carrier reel.

BACKGROUND OF THE INVENTION

[0001] (i) Field of the Invention

[0002] The present invention relates to a carrier reel used for carrying a plurality of products, electronic components of, e.g., a semiconductor apparatus in particular, and to a carriage method using the carrier reel.

[0003] (ii) Description of the Prior Art

[0004] In case of carrying electronic components of, e.g., a semiconductor apparatus, there is adopted a carriage method by which a carrier tape which is a tape accommodating a plurality of electronic components therein are wound around the carrier reel and the carrier reel is fed to carry a plurality of electronic components.

[0005] The carrier reel used in this method has such a structure as that a flange portion consisting of two surfaces which is distanced from each other by a tape width and provided in parallel with and opposed to each other is connected to a hub portion provided between the two surfaces.

[0006] In the carriage method for electronic components adopting such a carriage method, after carriage, an axial rod is inserted into a through hole and the like provided in the center of a body portion of the real to mount the carrier reel having the carrier tape wound around the reel on an automatic assembling line, and the individual electronic components are supplied by drawing the carrier tape, thereby performing mounting and assembling of each electronic component.

SUMMARY OF THE INVENTION

[0007] It is, therefore, an object of the present invention to provide a carrier reel for carrying a plurality of electronic components, by which the volume of the entire package becomes constant irrespective of characteristics of the electronic components to be carried and to provide a carriage method using the carrier reel.

[0008] To achieve this aim, the present invention provides a carrier reel comprising: a flange portion having a first surface and a second surface which is opposed to and substantially parallel to the first surface; and a hub portion which is provided between the first surface and the second surface and connected to the flange portion, a carrier tape in which a plurality of electronic components are mounted being wound around the hub portion, accommodation portions accommodated a drying agent being provided to the hub portion.

[0009] In addition, the present invention provides a carriage method using the carrier reel comprising: winding a carrier tape in which a plurality of electronic components are mounted around a hub portion of a carrier reel which comprises a flange portion having a first surface and a second surface which is opposed to and substantially parallel to the first surface and a hub portion which is provided between the first surface and the second surface and is connected to the flange portion, the hub portion having accommodation portions accommodated a drying agent provided thereto; accommodating the drying agent in the accommodation portions; and putting the carrier reel around which the carrier tape is wound into a bag, sealing the bag and performing carriage after accommodating the drying agent in the accommodation portions.

BRIEF DESCRIPTION OF THE DRAWINGS

[0010] While the specification concludes with claims particularly pointing out and distinctly claiming the subject matter which is regarded as the invention, it is believed that the invention, the objects, features and advantages thereof will be better understood from the following description taken in connection with the accompanying drawings in which:

[0011] FIG. 1 is a cross-sectional view showing a carrier tape in a first embodiment according to the present invention;

[0012] FIG. 2 is a plane view of a carrier reel in the first embodiment according to the present invention;

[0013] FIG. 3 is a perspective view of the carrier reel in the first embodiment according to the present invention, taken along the line III-III in the plane view;

[0014] FIG. 4 is an inclined plane view showing a carriage method using the carrier reel in a second embodiment according to the present invention; and

[0015] FIG. 5 is a schematic view showing a packaging method for electronic components using the carrier reel in the second embodiment according to the present invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0016] Preferred embodiments according to the present invention will now be described with reference to the accompanying drawings.

[0017] FIGS. 1 to 3 are views showing a first embodiment according to the present invention. FIG. 1 is a cross-sectional view of a carrier tape wound around a carrier reel of this embodiment; FIG. 2, a plane view of the carrier reel; and FIG. 3, a cross-sectional view taken along the III-III line in FIG. 2.

[0018] Description will first be given as to the carrier tape wound around the carrier reel in this embodiment.

[0019] As shown in FIG. 1, a carrier tape 1 in which electronic components are accommodated is constituted by a carrier tape main body 1a and a cover tape 1b. Embossed pockets 3 which are concave portions are provided to the carrier tape main body 1a at predetermined intervals in the lengthwise direction. A chip type electronic component such as a capacitor or an LSI mounted on a printed board is accommodated in each embossed pocket 3. Particularly, in FIG. 1, a resin sealed type semiconductor device 2 which is easily affected by humidity during carriage, e.g., a semiconductor device sealed by epoxy-based mold resin is accommodated. Further, the cover tape 1b prevents an electronic component accommodated in the embossed pocket 3 from coming off.

[0020] FIGS. 2 and 3 are views showing a carrier reel in the first embodiment.
