Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a carrier tape used for taping and packaging small electronic components such as chip capacitors, ceramic capacitors and resistors used in electronic equipment such as computers, and more particularly to sprocket holes. The present invention relates to a storage carrier tape of a type in which electronic components are removably attached to a tape-shaped tape body by a non-adhesive method and wound around a reel.

[0002]

2. Description of the Related Art Chiped electronic parts such as diodes, capacitors and transistors used in electronic devices such as computers are packaged by a method of storing them in a strip-shaped tape body generally called a carrier tape and winding them on a reel. ing. As a carrier tape used in this method, for example, a paper or plastic tape body provided with a storage box and a sprocket hole of a predetermined size, or a band-shaped tape body provided with a large number of storage holes are formed. , The bottom of which is formed by adhering a tape with an adhesive layer on one side of the tape body (Actually published No. 57-157199).
(See Japanese Patent Laid-Open Publication), a double-sided adhesive tape having a double-sided adhesive of arbitrary shape and size attached to one side of the strip-shaped tape body at regular intervals is known.

[0003]

Among the conventional carrier tapes described above, in the case of a carrier tape using a double-sided adhesive, it is difficult for the carrier tape of the type to be housed in a box to be detached or displaced. Although there are advantages, there is a drawback that when the double-sided adhesive cures, it separates from the tape body together with the parts and falls off. Further, in the case of this type of carrier tape, the tape body (mounting paper, plastic film, etc.) once used cannot be reused repeatedly because of adhesive residue and must be discarded, which is uneconomical. In addition, the conventionally used double-sided adhesive cannot be applied to, for example, electronic parts made of silicon, so that the application is limited in terms of material, and it is not adhered if dust or oil adheres to the adhered surface. There are drawbacks. Further, this type of carrier tape is not suitable for accommodating components having lead portions.

In order to eliminate the above-mentioned drawbacks of the prior art, the present invention uses a non-adhesive type rubber substance which does not leave an adhesive residue, so that the tape body can be repeatedly used and no material is used. The present invention intends to propose a carrier tape for storing electronic components, which can be applied to all electronic components regardless of their use and can sufficiently cope with adhesion of dust and oil.

[0005]

SUMMARY OF THE INVENTION The present invention is a carrier tape capable of attaching and detaching electronic components by means of so-called glue instead of double-sided adhesive which has been used conventionally. A double-sided adhesive material having a constant thickness and made of a rubber-based material to be adhered by means of is attached at intervals, and an electronic component can be detachably mounted on the double-sided adhesive material.

[0006]

The rubber-based material adhered by the non-adhesive method in the present invention is so-called foam-like, and when a component is pressed against the surface, the component is attached by the suction action of the air trapped in the pores. Although the adhesive strength of the component is inferior to that of the conventional adhesive, the adhesive strength is such that the electronic component does not move or come off. Rubber materials having such characteristics have the characteristics that they can be easily attached and detached from any material such as paper and plastic, have no adhesive residue, and can be used repeatedly, and thus have a wide range of uses. .

The double-sided adhesive material made of this rubber-based material is in the form of a tape having a certain thickness and width. When it is used as a carrier tape, it can be arbitrarily selected according to the size and shape of electronic parts. The shape and size of the tape are attached to the strip tape body at intervals. It is also possible to use the tape in the form of a tape attached to the center of one side of the tape body. The electronic component can be attached by simply pressing it on the double-sided adhesive material, and can be easily taken out by a suction method or the like. Further, since the double-sided adhesive material has a certain thickness, the component can be floated and attached from the tape body. Therefore, even a component having a lead portion can be stored without any influence on the lead portion. Further, after the parts are taken out, the double-sided adhesive material remains on the tape body as it is, so that it can be reused.

Further, in order to prevent the double-sided adhesive material from transferring to the back surface of the tape body when wound on a reel, the back surface of the tape body is subjected to a peeling treatment. When no peeling treatment is applied, a strip-shaped release paper may be used. In this case, the strip-shaped release paper is placed on the double-sided adhesive material.

Since the tape body has a sprocket hole, the tape body can be automatically fed by using this sprocket hole, and the position of the hole can be detected by a photoelectric tube or the like to control the tape feeding. Therefore, a double-sided adhesive material of arbitrary shape and size can be attached to the tape body with considerable accuracy.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a perspective view showing a part of a carrier tape according to the present invention, and FIG. 2 is an enlarged side view showing a state where electronic components with leads are attached to the same tape. A tape body, 2 is a sprocket hole, 3 is a rubber-based double-sided adhesive material, and 4 is an electronic component.

That is, the carrier tape according to the present invention has a structure in which the rubber-based double-sided adhesive material 3 is adhered to the paper tape body 1 having the sprocket holes 2 at the side end portions at substantially regular intervals. It is a thing. The back surface of the paper tape body 1 is peeled off. Needless to say, the tape body is not limited to paper. When this carrier tape is wound on a reel (not shown), the double-sided adhesive 3 comes into contact with the back surface of the tape body 1, but since the back surface of the tape body 1 is peeled off as described above, the both surfaces are The adhesive does not transfer to the back surface of the tape body.

For example, when the electronic component 4 with a lead portion is stored in a carrier tape wound on a reel, another reel is attached while the carrier tape is rewound and the electronic component 4 is adhered to the double-sided adhesive material 3 of the tape. It is rolled up and stored.
In the case of this carrier tape, since the double-sided adhesive material 3 has elasticity, the pressure bonding force at the time of bonding the electronic component 4 is absorbed, and the tape body can be bonded stably and reliably without deformation. Further, since the double-sided adhesive material 3 has a constant thickness, the lead portion 4-1 is not bent or deformed.

When using the electronic component 4 thus tape-packaged, the tape can be rewound from the reel again, and the component can be taken out by, for example, a chucking method or a suction method. At that time, the double-sided adhesive material 3 does not adhere to the electronic component 4 and is not taken out, and the double-sided adhesive material 5 remains on the tape body as it is. Therefore, the carrier tape can be used repeatedly.

[0014]

As described above, since the carrier tape according to the present invention is a system for accommodating electronic parts by a non-adhesive type adhesive means that does not cause adhesive residue, the tape can be used repeatedly and the material can be used. Regardless of the type, all electronic parts can be stored, and it can handle dust and oil, and the adhesive to which electronic parts are attached has a certain thickness and floats above the tape body surface. Since it can be attached, even a component having a lead has an excellent effect that it can be stored without bending or deforming the lead portion.
