Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a carrier tape for taping various devices such as a semiconductor device having a plurality of lead terminals protruding on both sides of a main body.

[0002]

[Prior art]

 Conventionally, a carrier tape for taping such a device is configured, for example, as shown in FIG. That is, in FIG. 4, the carrier tape 1 has a long tape body 2 made of, for example, polypropylene, which extends in the left-right direction, and an embossed tape body 2 arranged along the longitudinal direction of the tape body 2. Thus, it is composed of a concave portion 3 having an open upper portion, and a cover tape 4 which is brought into close contact with the upper surface of the tape body 2 by thermocompression bonding or the like.

The recessed portion 3 is formed in such a shape that the device 5 can be accommodated from above, and the central portion of the bottom surface of the recessed portion 3 is trapezoidal upward in the recessed portion 3. The support surface 3a is formed so as to project. The supporting surface 3a is formed narrower than the width of the main body 5a of the device 5 to be housed, as shown in the figure.

Here, the device 5 includes, for example, a main body 5a formed in a substantially flat rectangular parallelepiped shape, and a plurality of lead terminals 5b protruding downward from both side surfaces of the main body 5a toward the outside in a crank shape. Is equipped with.

According to the carrier tape 1 configured as described above, after the device 5 is housed in each of the recessed portions 3 of the tape body 2 as shown in the figure, the heat is applied to the upper surface of the carrier tape 1. The cover tape 4 made of, for example, PET is brought into close contact by pressure bonding. By winding the carrier tape 1 in which the device 5 is accommodated in each recess 3 and the cover tape 4 is adhered in this manner around a reel (not shown), taping of a predetermined diameter is completed. .

Thus, in each device 5, the main body 5a is supported by the supporting surface 3a in the corresponding recessed portion 3, so that the lead terminal 5b contacts the bottom surface of the recessed portion 3. Then, it is not deformed or broken.

[0007]

[Problems to be solved by the device]

 However, in the taping of such a configuration, each device 5 has only its main body 5a placed on the supporting surface 3a of the recessed portion 3, and is locked in the lateral direction. Absent. Therefore, when a lateral force is applied to the carrier tape 1 or the recessed portion 3 itself of the carrier tape 1 is tilted, the device 5 has a support surface in the recessed portion 3. It will move laterally with respect to 3a. Therefore, each lead terminal 5b of the device 5 hits the side wall of the recessed portion 3, and the lead terminal 5b may be deformed or broken in some cases, and the yield of the device 5 may be increased. However, there was a problem that

Further, as the device 5 moves in the recessed portion 3, the device 5 is taken out from each recessed portion 3 of the carrier tape 1 by an automatic mounting machine, and the device 5 is automatically mounted on a printed circuit board or the like. If this is done, the accuracy of taking out the device 5 will decrease. Therefore, in some cases, the automatic mounting machine cannot take out the device 5, and the yield of the automatic mounting of the device 5 is reduced.

In view of the above points, the present invention has an object to provide a carrier tape for taping a device, which can prevent lateral movement of the device in the recess.

[0010]

[Means for Solving the Problems]

 According to the present invention, the above object has a plurality of recesses formed so as to be arranged along the longitudinal direction of the tape body, and each recess has a trapezoidal shape at the central portion of its bottom surface. When the device is housed in each recess, the supporting surface supports the bottom surface of the device body and the cover tape is adhered to the upper surface of the tape body by thermocompression bonding. In the carrier tape, the carrier tape is characterized in that both side edges of the above-mentioned supporting surface are provided with projecting ridges projecting upward, and the device is housed in the both ridges. To be achieved.

[0011]

[Action]

 According to the above configuration, since the trapezoidal support surface of the recessed portion provided in the tape body protrudes at both side edges, when the device is housed in the recessed portion, the device is That is, both sides of the main body can be laterally locked by both side edges of the supporting surface of the recess. This allows the device to move laterally on the support surface even when lateral forces are applied to the carrier tape or the recesses in the carrier tape itself are tilted. Instead, it can be fixed substantially. Therefore, since each lead terminal of the device does not hit the side wall of the recessed portion, the lead terminal is not deformed or broken.

Further, since each device does not move in the lateral direction in the recessed part, when the device in the recessed part is automatically mounted at a predetermined position such as a printed circuit board by the automatic mounting machine, the take-out accuracy is improved. It will be improved and each device can be taken out reliably.

【Example】

 Hereinafter, the present invention will be described in detail with reference to the embodiments shown in the drawings. FIG. 1 shows an embodiment of a carrier tape according to the present invention. In FIG. 1, a carrier tape 10 is formed by a long tape body 11 made of, for example, polypropylene, which extends in the left-right direction, and by embossing or the like so as to be aligned along the longitudinal direction of the tape body 11. It is composed of a concave portion 12 whose upper part is open and a cover tape 13 which is brought into close contact with the upper surface of the tape body 11 by thermocompression bonding or the like.

The recess 12 is formed in a shape such that the device 14 can be accommodated from above, and the central portion of the bottom surface of the recess 12 is substantially trapezoidal in the recess 12. It is provided with a support surface 12a formed so as to project toward.

The above structure is similar to that of the conventional carrier tape 1 shown in FIG. 4, but in the carrier tape 10 according to the present invention, the supporting surface 12a is a device to be accommodated as shown in the drawing. 14 is formed to be a little wider than the width of the body 14a of the device 14, and also has ridges 12b projecting upward on both side edges so as to sandwich the side edge of the body 14a of the device 14. , Formed.

The carrier tape 10 according to the present invention is constructed as described above, and when used, each device 14 is first placed in each recess 12 of the tape body 11 as shown in FIG. After accommodating the device 14 so that the lead terminals 14b of the carrier tape 10 extend in the longitudinal direction of the tape body 11, the cover tape 13 made of, for example, PET or the like is formed on the upper surface of the tape body 11 of the carrier tape 10 by thermocompression bonding. To be in close contact. In this way, the carrier tape 10 in which the device 14 is housed in each recess 12 and the cover tape 13 is adhered is wound around a reel (not shown), whereby taping with a predetermined diameter is completed. .

In this case, each device 14 has its main body 14a supported by the support surface 12a in the corresponding recessed portion 12, and both side edges thereof can be laterally locked by the protruding portions 12b. . As a result, the lead terminal 14b of each device 14 contacts the bottom surface of the recessed portion 12 so as not to be deformed or broken, and at the same time, a lateral force is applied to the carrier tape 10. Device 14 or the recess 12 itself of the carrier tape 10 is tilted, the device 14 does not substantially move laterally on the support surface 12a, and the device 14 does not move substantially. It will be fixed.

In the above embodiment, each device 14 is housed in the recess 12 so that its lead terminal 14 b extends along the longitudinal direction of the tape body 11. Not limited to this, as shown in FIG. 3, each device 14 may be housed in the recess 12 so that its lead terminal 14 b extends in a direction perpendicular to the longitudinal direction of the tape body 11. That is clear.
