Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a carrier tape for carrying electronic parts used for obtaining a taping package for electronic parts such as ICs and LSIs, and a hard protective cover used for the carrier tape.

[0002]

2. Description of the Related Art Recently, in order to automatically produce various electronic devices, electronic parts have been automatically mounted on a circuit board. In order to facilitate the handling of electronic components in the process of automatically mounting the electronic components, a taping package in which individual electronic components are packaged in a tape-shaped carrier is used. The automatic mounting is performed so that the electronic components sequentially sent out in step 1 are automatically mounted on a predetermined circuit board.

Some taping packages used for automatic mounting of such electronic components use a tape having an adhesive portion. 9 and 10 show an example of an adhesive carrier tape used for a conventional taping package. FIG. 10 is a sectional view taken along the line BB of FIG. In this type of tape, feed holes 6 are provided at one side or both sides of a base tape 2 made of paper or other material at regular intervals, and the central portion of the base tape 2 in the width direction is Windows are opened at predetermined intervals in the length direction of the base tape 2. Further, on the adhesive tape attaching surface 2a of the base tape, the adhesive tape 3 is provided at the central portion in the width direction.
Is adhered, and the adhesive surface 3a of the adhesive tape 3 is exposed at the window portion opened in the base tape so that the adhesive surface 3a is exposed by facing the electronic component fixing surface 2b of the base tape 2. The bay window 5 is formed.

An electronic component 4 such as an IC or LSI is aligned and supplied on the adhesive surface exposing window 5 of the adhesive carrier tape, and is fixed to the adhesive surface 3a exposed from the adhesive surface exposing window 5. A sprocket (not shown) is fitted in the feed hole 6 provided on the side portion of the base tape 2, and the adhesive carrier tape is fed by the rotation of the sprocket, and the electronic component 4 on the tape is transported.

FIG. 3 shows a conventional adhesive carrier tape at the time of winding. The adhesive carrier tape 7 to which the electronic components 4 that have been aligned and supplied are fixed is wound up on a winding reel 9 as shown in FIG. 3 and is shipped as a taping package.

[0006]

By the way, the adhesive carrier tape is wound up toward the center of the reel as the tape is wound, and at that time, the IC or IC fixed to the electronic component fixing surface of the adhesive carrier tape is wound. An electronic component such as an LSI is rubbed on the back surface of the adhesive tape of the adhesive carrier tape on the outside of the tape winding. Therefore, in the conventional adhesive carrier tape of this type, the electronic component was peeled off from the adhesive surface and dropped, or the electronic component was scratched by friction with the tape.

[0007] The taping package used for transportation is a wound body in a state in which the electronic component fixing surface is wound inside, and therefore, when a force is applied to the wound body from the outside during transportation. In some cases, the tightening is loose and electronic parts such as ICs and LSIs may fall out and be lost from the taping package. Further, even if the electronic components have not been lost, the electronic components peeled off from the adhesive surface at the time of winding are loosened in order to mount these electronic components on a predetermined circuit board or the like. There were accidents in which the adhesive carrier tape fell off and could not be mounted on a circuit board or the like, or the angle was misaligned, causing mounting failure.

Even before the adhesive carrier tape is wound, electronic parts such as ICs and LSIs are transferred in an exposed state, and therefore, parts of the conveying device may be contacted and damaged during the transfer. There was also the danger of falling out or loss.

On the other hand, the present invention is an IC or an LSI.
