Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a series of taped chip-shaped electronic components.

As shown in FIG. 1A and 1B, the conventional chip-shaped electronic component series stores a plurality of chip-shaped electronic components 1 in recesses 3 provided in a continuous mounting tape 2, and covers them with an adhesive cover tape 4. A glued version was used.

However, in general, when electrolytic capacitors are stored for a long time, their leakage current tends to increase, and they may be aged by applying voltage again. In such cases, there was a drawback that it was not easy to apply electricity.

The present invention eliminates the above-mentioned drawbacks and provides a series of chip-shaped electronic components that can be easily energized with taped chip-shaped electronic components.

The present invention will be explained below with reference to embodiments shown in FIGS. 2 to 4.

FIG. 2A shows a mounting tape 5 made of plastic or the like, and a recess 6 into which a chip-shaped electronic component 1 can be inserted is formed in the tape 5. 7 is a tape feeding hole. FIG. 2B shows a cover tape 8 such as an adhesive tape, and when it is attached to the mounting tape 5, two energized conductive tapes made of conductive tape are arranged so that they come into contact with the solderable electrode portions 9 of the chip-shaped electronic component 1. A conductive material 10 for use is provided.

A chip-shaped electronic component 1, for example, a polar chip-shaped electrolytic capacitor, is attached to the electrode portion 9 using a taping material consisting of the above-mentioned mounting tape 5 and cover tape.
The cover tape 8 is inserted into the recess 6 so that the polarities are in the same direction, and the cover tape 8 is pasted to complete the process as shown in FIG. 2C.

The chip-shaped electronic component series of the present invention is constructed as described above.

Therefore, in a series of chip-shaped electronic components in which the chip-shaped electronic components 1 are taped and packaged by a method such as winding on a reel or zigzag, all the chip-shaped electronic components 1 are passed from the end of the taping material through the conductive material 10 for electricity supply. Since they can be connected in parallel and energized, voltage can be easily applied from one end of the taping material when aging is required, such as in an electrolytic capacitor. The depth of the recess 6 can be made shallower than the thickness of the chip-shaped electronic component 1, and the contact can be made stronger.

3 to 5 show other different embodiments. In FIG. 3, a mounting tape 11 is provided with a punched hole 12 into which a chip-shaped electronic component 1 is inserted, and a cover tape 13, 14 is provided with a punched hole 12 for inserting an electronic component 1. One continuous electrically conductive material 10 is provided so that the two electrode parts 9 of 1 are in contact with each other separately, and a mounting tape 11 is provided.
Cover tapes 13 and 14 are bonded to both sides of the cover tape, and the same effect is obtained.

FIG. 4 shows an example in which the punched hole 12 in FIG. 3 is removed, and the same effect is obtained.

In FIG. 5, the electrically conductive material 10 is extended to the side surface of the recess 6 provided in the mounting tape 5, and comes into contact with the electrode portion 9 of the chip-shaped electronic component 1, producing the same effect.

Note that instead of the continuous conductive tape of the conductive material 10 described above, a part of the taping material may be continuously metal-deposited to provide a conductive path, or a thin flexible conducting wire may be arranged. . Further, the mounting tape or cover tape may be made of an electrically conductive material, and the portions to be insulated may be covered with an insulating material. The above-mentioned conductive material for current-carrying may be provided on either side of the adhesive tape or mounting tape, and in either case, at least a portion of the taping material is made of a continuous conductive material for current-carrying, and chip-shaped electronic components are attached to the conductive material. 1 electrode part 9
are held in contact with each other, and various combinations are possible.

Further, by coloring one pole side of the above-mentioned conductive material for energization, the polarity classification when energizing can be made clearer and safety can be improved.

Figure 6 compares the leakage current characteristics of an electrolytic capacitor with a rating of 50WV and 1μF, which is obtained by aging a sample taped according to the present invention and by a conventional product which is taped after aging. It was confirmed that the device of the present invention has significantly reduced leakage current and is stable. Furthermore, it was demonstrated that the variation in leakage current was small and it was effective.

As mentioned above, the chip-shaped electronic component series of the present invention is
It is extremely advantageous in terms of quality and energization treatment, and has great industrial and practical value.
