Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides an IC for storing and forging a hybrid IC.
This relates to a storage body, and more specifically, a second elongated case that accommodates an IC is connected to a first elongated case that is cylindrical or has a concave cross section.
This invention relates to an IC storage body housed in a case.

[Conventional technology]

Conventionally, as a storage body for electronic parts, for chip parts,
In some cases, a housing cavity is formed in a paper or resin tape, a chip component is stored in the cavity, and then the cavity is sealed with a cover sheet.

Furthermore, for use in so-called IC packages in which ICs are housed in resin molds or ceramics, there are elongated cylindrical bodies having an internal cross-sectional shape similar to the cross-sectional shape of the IC package.

In addition to the IC housed in the above-mentioned puff cage, a fourth
A bare IC chip 52 is mounted on a substrate 51 as shown in FIG.
The so-called hybrid IC 55 is a so-called hybrid IC 55 in which the input/output terminals 53 are mounted in a specific direction of the substrate 51 and the substrate 51 is molded with an exterior resin 4 so as to cover the bare IC chip 2.
However, the storage body 56 shown in FIG. 4(b) is used.

FIG. 4(b) is an external view of a conventional storage body.

56 is a cylindrical extrusion-molded storage body made of vinyl chloride, polycarbonate, etc., and the interior 5 of the cylindrical storage body 56
Reference numeral 7 indicates the shape of the IC 55, specifically, it is molded into a predetermined shape so as to separate the substrate 51 and the terminals 53 so that stress is not applied to the terminals 53 when the IC 55 is stored.

A plurality of ICs 55 were housed in the interior 57 in an orderly line.

This storage body 56 is set in an automatic loading machine etc., and the IC55
When mounting on a predetermined electric circuit board (not shown),
The storage body 56 was tilted and fed to the automatic loading machine by the weight of the IC 55.

[Problem to be solved by the invention]

However, even if the above-mentioned storage body 56 is set in an automatic loading machine and tilted, the surface of the IC 55 is uneven, unlike an IC package, so the IC 55 is tilted inside 57, and the inside 57 is tilted. There was a problem that the IC 55 could not be fed to the automatic loading machine by its own weight because it got caught on the inner wall or the part 59 that separates the board 51 and the terminal 53 (this occurs with a probability of 2 to 3%). In addition, the above-mentioned storage body 5
6, the shape of the storage part which is the inside 57 is IC55
The decision was made based on the shape of the Therefore, the exterior resin 54
For this type of IC55, which often has different external dimensions, it is necessary to use many types of storage bodies 56 according to the IC55 of each size, which not only increases the cost of the storage body 56 itself but also the cost of the automatic loading machine. There was a problem in that it had to be adjusted according to each storage body 56.

That is, it is difficult to make the above-mentioned storage body 56 compatible with an automatic loading machine.

In addition, an IC 55 is provided in the storage part which is the inside 57 of the storage body 56.
In the work of storing the storage bodies 56, it is necessary to store them one by one from the loading port 58 on one side of the storage body 56, and such difficult manual work is required.

The present invention has been devised in view of the above-mentioned problems,
The purpose of this is to make it easy to store and remove ICs from the storage body, to be compatible with automatic loading machines, and to create ICs with excellent versatility.
The purpose is to provide a storage body.

[Technical means to solve the problem]

The technical means taken by the present invention to achieve the above-mentioned object include a first case having a support protrusion integrally formed opposite to an inner wall, guided by the support protrusion;
A second elongated case for accommodating the IC is accommodated in a supported manner, and locking means for fixing the second case are formed near openings at both ends of the first case.

[Effect]

According to the above-mentioned IC storage body, the ICs are accommodated in the plurality of holding holes formed in the second case, and the second case is formed on the inner wall side of the elongated first case having a cylindrical shape or a concave cross section. By sliding the end portion of the second case into the first case while supporting the end portion of the second case on the support protrusion, the IC is housed together with the second case inside the first case.

That is, it is only necessary to place the IC to be stored in the holding hole of the second case, which eliminates the difficult task of storing the IC toward the openings at both ends of the first case, and also allows the IC to be placed on the second case. Because it is stored in an orderly manner, I
There will be no clogging of C.

Further, for a wide variety of ICs, the external dimensions of the first case can be kept constant by simply selecting the second case from a plurality of types of second cases having different shapes of holding holes.

This eliminates the need for A adjustment for automatic loading machines, improving compatibility with automatic loading machines.

Furthermore, the general-purpose usability of the first case is improved, and a low-cost storage body is achieved as a whole.
