A pair of sides facing each other is referred to as side sides 23 and 24. The wiring board 3 is formed to be narrower than the distance between the pair of side edges 23 and 24.

Next, the storage body 10 will be described. The storage body 10 has a plurality of unit storage bodies 20 and is packed in a state where the plurality of unit storage bodies 20 are stacked.
The unit storage body 20 includes a tray 30, a first sheet member 40, and a second sheet member 50.

  The tray 30 is made of, for example, a synthetic resin such as PET, PP, PS, and has a rectangular bottom plate 31 and a side wall 32 standing from the peripheral edge of the bottom plate 31. Specifically, the side wall 32 is erected from the four sides of the bottom plate 31 so that the region surrounded by the side wall 32 has a rectangular shape.

FIG. 2 is a top view illustrating a schematic configuration of the first sheet member 40. The first sheet member 40 is a sheet member made of foamed plastic, for example, and is formed in a rectangular shape so as to have four side portions respectively opposed to the side wall 32 as shown in FIGS. The first sheet member 40 is formed in a size that fits within a region surrounded by the side wall 32 when placed on the bottom plate 31. In addition, it is preferable to make the clearance gap between the 1st sheet member 40 and the side wall 32 as small as possible in order to prevent the rattling during conveyance.
Further, the first sheet member 40 is formed with a plurality of openings 41 for individually storing the electronic members 1. The first sheet member 40 is formed in such a thickness that the upper or lower portion of the electronic member 1 does not protrude from the upper or lower surface of the first sheet member 40 when the electronic member 1 is stored in the opening 41.

The opening 41 is an opening that penetrates from the upper surface to the lower surface of the first sheet member 40, and a main body storage portion 42 in which the main body portion 2 of the electronic member 1 is stored, and the wiring substrate 3 is stored in the main body storage portion 42 And a wiring board storage portion 43 to be provided.

In the first side 421, an opening 425 that is continuous with the wiring board housing portion 43 is formed. All of the second sides 422 are in contact with the other end 22 of the main body 2. Both ends of the third side 423 and the fourth side 424 are in contact with the main body 2, and the intermediate portions 426 and 427 are separated from the main body 2. Intermediate portions 426 and 427 between the third side 423 and the fourth side 424 are formed in a semicircular shape so that a finger can easily enter.

  The wiring board storage portion 43 is formed so as to be connected to the main body storage portion 42 through the opening 425 of the main body storage portion 42. The wiring board housing portion 43 surrounds the wiring board 3 so as not to contact the wiring board 3.

The second sheet member 50 is made of, for example, foamed plastic such as foamed polyethylene, and two sheets are provided for each unit storage body 20 as shown in FIG. The second sheet member 50 is formed in a rectangular shape whose outer shape is substantially the same as that of the first sheet member 40 so as to cover all the openings 41 of the first sheet member 40. Further, the second sheet member 50 is formed thinner than the first sheet member 40. The two second sheet members 50 included in one unit storage body 20 are placed on the bottom plate 31 of the tray 30 so that the second sheet member 50 is placed below the first sheet member 40 after packing. The other second sheet member 50 is placed on the first sheet member 40 to cover the upper side of the first sheet member 40.
The sum of the thickness of the two second sheet members 50 used in the unit storage body 20 and the thickness of the first sheet member 40 is set to be the same as the depth of the tray 30.

Next, a method for packing the electronic member 1 will be described.
First, the tray 30 and the electronic member 1 are prepared (tray preparation process, electronic member preparation process).
Next, the electronic member 1 is fitted into the opening 41 of the first sheet member 40 (fitting step). At this time, the second side 422, the third side 423, and the fourth side 424 of the opening 41 are in contact with the main body 2 of the electronic member 1.

Next, the two second sheet members 50 are arranged so as to overlap the opening 41 of the first sheet member 40 (second sheet member arranging step). Of the two second sheet members 50, one second sheet member 50 is disposed below the first sheet member 40, and the other second sheet member 50 is disposed above the first sheet member 40.
Then, the superposed first sheet member 40 and second sheet member 50 are placed on the bottom plate 31 inside the side wall 32. (Installation process). Thereby, one unit storage body 20 is formed. The above process is repeated to form a plurality of unit storage bodies 20 and stack the plurality of unit storage bodies 20 (lamination process).

Thereafter, as shown in FIG. 3, a plurality of stacked unit storage bodies 20 are stored together with a desiccant 6 in a flexible container 5 made of, for example, a seal bag, and sealed while sucking the gas in the container 5. (Sealing process).
Next, after the plurality of sealed unit storage bodies 20 are stored in the carton box 7, the carton box 7 is stored in the inner box 8. At this time, the upper and lower surfaces of the carton box 7 are covered with the intermediate plate 71.
After being stored in the inner box 8, the upper part of the inner box 8 is closed and sealed with tape 9 as shown in FIG. After sealing, the inner box 8 is stored in the outer box 11, and the upper part of the outer box 11 is closed and sealed with tape 9 as shown in FIG. 5. Thereby, the packaging of the electronic member 1 is completed.

  As described above, according to the present embodiment, when the electronic member 1 is packed, the electronic member 1 is stored in the opening 41 of the first sheet member 40, and the first sheet member 40 is stored in the bottom plate 31 of the tray 30. Therefore, it is not necessary to remake the tray 30 made of synthetic resin every time the shape of the electronic member 1 is different. On the other hand, the first sheet member 40 needs to be remade so as to have an opening 41 corresponding to the shape of the electronic member 1 every time the shape of the electronic member 1 is different. It is possible to remake the resin tray 30 at a lower cost than remaking it. As described above, since the highly versatile tray 30 can be used to store the electronic member 1, it is possible to suppress the cost for packaging.

  Further, since the plurality of second sheet members 50 are provided for each unit storage body 20, the upper and lower portions of the first sheet member 40 can be covered with the second sheet member 50. Thereby, since the upper surface and lower surface of the electronic member 1 are covered with the 2nd sheet | seat member 50, the surface of the electronic member 1 can be protected. Furthermore, even if the shape of the electronic member 1 is changed and the thickness of the first sheet member 40 is reduced while the depth of the tray 30 remains the same, the thickness direction is adjusted by adjusting the number of the second sheet members 50. It becomes possible to fill the gap.

Moreover, since the sum of the thickness of the second sheet member 50 used for the unit storage body 20 and the thickness of the first sheet member 40 is the same as the depth of the tray 30, the second sheet member is removed from the side wall 32 of the tray 30. 50 and the first sheet member 40 are prevented from protruding.
Further, the third side 423 and the fourth side 424 of the opening 41 of the first sheet member 40 are in contact with the main body 2 of the electronic member 1 at both ends, and the intermediate portions 426 and 427 are separated from the main body 2. Therefore, the electronic member 1 can be easily removed from the opening 41 by inserting a finger into the intermediate portions 426 and 427.
Further, since the intermediate portions 426 and 427 are provided at the edge of the main body storage portion 42, when removing the electronic member 1 from the opening portion 41, a finger is applied to the main body portion 2 having higher rigidity than the wiring board 3. You can hang it. Therefore, it is possible to easily remove the electronic member 1 from the opening 41 as compared with the case where the wiring board 3 is removed with a finger.

Note that the present invention is not limited to the above embodiment, and can be modified as appropriate. In the following description, the same parts as those in the above embodiment are denoted by the same reference numerals and the description thereof is omitted.
For example, in the above embodiment, the case where the sum of the thickness of the second sheet member 50 used in the unit storage body 20 and the thickness of the first sheet member 40 is the same as the depth of the tray 30 has been described as an example. When the second sheet member 50 is not used, the thickness of the first sheet member 40 and the depth of the tray 30 are preferably the same.

  Moreover, FIG. 6 is explanatory drawing which shows the modification of the 1st sheet member 40 and the 2nd sheet member 50, (a) is a top view which shows the modification of an upper 2nd sheet member, (b) is 1st. The top view which shows the modification of a sheet | seat member, (c) is a top view which shows the modification of a lower 2nd sheet | seat member. As shown in FIG. 6, a first notch 45 that is recessed inward is formed on one of the four sides of the first sheet member 40A. The first notch 45 is formed in a semicircular shape so that a finger can easily enter. The predetermined part of the first notch 45 is arranged closer to the wiring board storage part 43 than the main body storage part 42 in the nearest opening 41. Since the wiring board storage portion 43 is smaller than the main body storage portion 42, the remaining space can be effectively used as the first notch portion 45.

  The second sheet member 50A is formed with a second notch 46 that is recessed inwardly on one of the four sides. The first notch 45 is formed in a semicircular shape so that a finger can easily enter. The second notch 46 is formed so as to overlap the first notch 45 of the first sheet member 40A when the second sheet member 50A is viewed from the front side (see FIG. 6A). When the second sheet member 50A is turned upside down, the second notch 46 is disposed at a position where it does not overlap with the first notch 45 at all (see FIG. 6C).

  Moreover, in the said embodiment, although the intermediate locations 426 and 427 illustrated the case where it formed in the 3rd side 423 and the 4th side 424 of the main body accommodating part 42, in the 1st sheet | seat member 40A shown in FIG. A location 428 is formed in a corner portion including a second side 422a on the opposite side of the main body storage portion 42 from the wiring board storage portion 43 and a fourth side 424a. The intermediate portion 428 is formed in a substantially three-quarter shape so that a finger can easily enter. When the intermediate portion 428 is formed at the corner portion composed of the second side 422a and the fourth side 424a in this way, a finger can be put on the corner portion of the main body 2 of the electronic member 1, and the electronic member 1 Can be easily taken out.

  When the first sheet member 40A and the second sheet member 50A are used, the second sheet member 50A disposed immediately above the first sheet member 40A is shown in FIG. In this manner, the second cutout portion 46 and the first cutout portion 45 are arranged so as to overlap each other. On the other hand, the second sheet member 50A disposed below the first sheet member 40A is disposed so that the second notch 46 and the first notch 45 do not overlap each other as shown in FIG. Thus, when the second cutout portion 46 of the second sheet member 50A overlaps the first cutout portion 45 of the first sheet member 40A immediately below the second sheet member 50A, the second sheet member 50A and The first sheet member 40A can be easily removed from the tray 30 together.

  In addition to the installation location described above, for example, the intermediate location is the first location on the opposite side of the main body storage portion 42 from the wiring board storage portion 43, as in the intermediate location 429 of the first sheet member 40B shown in FIG. The center of the two sides 422b is set as the installation place, or the main body storage portion 42 and the wiring board storage portion 43 on the third side 423c and the fourth side 424c as in the intermediate portion 430 of the first sheet member 40C shown in FIG. For example, the vicinity of the boundary may be the installation location.

  In the above modification, in order to make it easy to remove the first sheet member 40A and the second sheet member 50A from the tray 30, the first sheet member 40A and the second sheet member 50A are provided with the notches 45 and 46. However, as shown in FIG. 9, a third notch 38 is provided on the side wall 32 of the tray 30, and a finger is inserted into the third notch 38 to connect the first sheet member 40A and the second sheet member 50A. You may make it remove from the tray 30. FIG. Since it is not necessary to change the position of the third notch 38 in accordance with the design change of the first sheet member 40A, also in this modification, the design change of the storage body that is required every time the shape of the electronic member is different. Such costs can be suppressed.
