Description

  The present invention relates to a carrier tape and a package.

  In general, for packaging electronic components such as LSIs and ICs, carrier tapes that are easy to handle and have excellent efficiency when mounting electronic components on a wiring board are used. The carrier tape has a plurality of recesses provided at predetermined intervals, and the electronic components are accommodated in the recesses.

  When the electronic component is housed in the concave portion of the carrier tape and the top cover tape is attached so as to close the opening of the concave portion, the electronic component is covered with a package including the carrier tape and the top cover tape. Further, the package is used for storage and transportation in a state of being wound around a reel.

  For example, Patent Document 1 proposes an embossed taping package in which an electronic component housed in a pocket (concave portion) of a carrier tape is sealed with a top cover tape and wound around a reel. Further, this embossed taping package is housed in an individual packaging box provided with impact buffering members at the four corners inside the box, and this individual packaging box is housed in an exterior box equipped with impact cushioning members at the four corners inside the box. Is done. That is, the packaging form for shipping electronic components described in Patent Document 1 is such that such an embossed taping package is housed in an individual packaging box and an outer packaging box.

  However, in the packaging form described in Patent Document 1, since the disk-shaped reel is housed in a rectangular parallelepiped or cubic individual packaging box, a large gap is formed between the reel and the individual packaging box, so that the loading efficiency is reduced. To do. Further, it may be necessary to use an impact buffering member to fill this gap. However, from the viewpoint of reducing the environmental load, there is a demand for reducing the use of such shock absorbing members.

  Moreover, when transporting by winding around a reel as in the prior art, curling occurs on the carrier tape. For this reason, it is also demanded to improve the reduction in work efficiency at the time of storing or taking out electronic components due to the curl.

<< First Embodiment >>
First, a first embodiment of the carrier tape and package of the present invention will be described.

  FIG. 1 is a top view and a longitudinal sectional view showing a first embodiment of the package of the present invention, FIG. 2 is a partially enlarged view of the package shown in FIG. 1, and FIG. 3 is another package shown in FIG. FIG. 4 is a longitudinal sectional view showing a state in which the packaging body shown in FIG. 1 is accommodated in an individual packaging box, and FIG. 5 is a diagram for explaining how the packaging body accommodated in the individual packaging box is taken out. FIG. In addition, in FIGS. 2-5, only the carrier tape is illustrated among the packaging bodies. 1 and 2, (a) is a top view and (b) is a longitudinal sectional view. In the following description, FIGS. 1 (b), 2 (b), and 3 are shown. 4 and 5, the upper side is referred to as “upper” and the lower side is referred to as “lower”.

  A package 1 shown in FIG. 1 is a packaging material for packaging an electronic component 10. Specifically, the packaging body 1 stores the electronic component 10 in an internal space formed between the carrier tape 2 and the top cover tape 3, and the electronic component 10 is affected by impact, contamination, etc. during storage or transportation. Protect.

  The present invention is characterized by the carrier tape 2 in the package 1. The carrier tape 2 is divided into a plurality of bent portions 21 that can be bent by 180 ° in the thickness direction and a plurality of non-folded portions 22 that are relatively difficult to bend. Each is provided intermittently via each non-bent portion 22. Such a carrier tape 2 accommodates the electronic component 10 and is folded in a so-called “spirally folded” shape by folding the bent portion 21 in a state of being laminated with the top cover tape 3, that is, in the state of the package 1. (See FIG. 4). For this reason, the folded package 1 can be put together in a rectangular parallelepiped shape, and can be stored in the rectangular parallelepiped individual packaging box with almost no gap. As a result, the amount of packaging material such as an impact buffering member can be suppressed, and a small and lightweight packaging form can be realized.

Hereinafter, the package 1 shown in FIGS. 1 and 2 will be described in detail.
The carrier tape 2 is obtained by performing various processes on a belt-like sheet, and includes a plurality of recesses (pockets) 23 along the longitudinal direction. Each of the recesses 23 can accommodate the electronic component 10. Such a recess 23 is formed, for example, by pressing a molding die corresponding to the shape of the recess 23 against the upper surface 20a of the sheet as a base material of the carrier tape 2 and press-molding. A through hole 231 is formed in the center of the bottom of each recess 23.

  The shape and depth of the recess 23 in a plan view ensure that the entire electronic component 10 is accommodated, and that the electronic component 10 can be moved from the recess 23 while preventing the electronic component 10 from shaking significantly in the recess 23 due to vibration during transportation. It is set so that an appropriate gap is secured between the electronic component 10 and the recess 23 so that it can be easily taken out. Moreover, these recessed parts 23 are provided at predetermined intervals along the central part in the width direction.

  On the other hand, a plurality of sprocket holes 29 are provided at equal intervals along the longitudinal direction at both ends (edges) in the width direction of the carrier tape 2. When the teeth of a sprocket wheel (not shown) are fitted into the sprocket hole 29, the carrier tape 2 can be conveyed according to the rotation of the sprocket wheel.

  Examples of the constituent material (material) of the carrier tape 2 include various resin materials such as polystyrene, polyethylene, polypropylene, polyester (polyethylene terephthalate, etc.), polycarbonate, polyvinyl chloride, cloth such as nonwoven fabric, paper, and the like. Is mentioned. If necessary, conductive fillers such as carbon black, graphite, and carbon fiber are mixed with these resin materials. As a result, conductivity is imparted to the carrier tape 2 and charging is prevented, so that destruction of the electronic component 10 due to static electricity is prevented. Furthermore, on the surface of the carrier tape 2, a release agent made of a silicone resin, a fluorine resin, or the like, a conductive film, or the like may be formed.

  Here, assuming that the interval between adjacent recesses 23 is an “interval portion”, a plurality of interval portions 24 are arranged in the carrier tape 2 along the longitudinal direction. The plurality of spacing portions 24 include a spacing portion 24 having a groove 241 cut in the thickness direction and a spacing portion 24 not having the groove 241 at a constant rate. And the space | interval part 24 provided with the groove | channel 241 exists intermittently for every predetermined number.

  Specifically, in the carrier tape 2 shown in FIG. 1, one interval portion 24 having the groove 241 and three interval portions 24 not having the groove 241 adjacent thereto are alternately arranged along the longitudinal direction. Are lined up. Therefore, in the carrier tape 2 shown in FIG. 1, the interval portion 24 provided with the groove 241 is indicated by the symbol “A”, the three interval portions 24 not provided with the groove 241 are indicated by the symbol “B”, and the recess portion 23 is indicated by the symbol “C”. ”Can be schematically shown as... CACBBCBCBCCABCBCBCBCACBC.

  Of the spacing portions 24 as described above, one spacing portion 24 (symbol “A”) provided with the groove 241 is a portion corresponding to the bent portion 21 described above. On the other hand, the three spacing portions 24 (symbol “B”) that do not include the groove 241 correspond to the above-described unfolded portion 22 together with the four recesses 23 (symbol “C”) arranged so as to sandwich them. It constitutes a part. Therefore, when the carrier tape 2 is folded in a zigzag manner, as shown in FIG. 3, the carrier tape 2 can be folded back by the spacing portion 24 (folding portion 21) provided with the groove 241, and the three spacing portions 24 and the four recess portions 23 can be folded. And the non-bending portion 22 including the two is folded so as to overlap one another in the thickness direction. That is, the symbol “A” corresponds to the bent portion 21, and the series of the symbols “B” and “C” corresponds to the non-bent portion 22.

  By the way, by providing the groove 241, the bent portion 21 is less rigid than the unfolded portion 22 in bending in the thickness direction. In other words, the bent portion 21 is more flexible than the non-bent portion 22. For this reason, the bent portion 21 is not only easily bent by applying a load, but if the load is removed and the original shape is restored, the original shape (unfolded state) is obtained even if a slight bending flaw remains. Can be maintained.

  Here, even if the conventional carrier tape is wound around the reel, it is not assumed to be folded. Therefore, even if a load is applied to bend in the thickness direction, the carrier tape cannot be sufficiently folded. For this reason, the volume after bending was not sufficiently reduced.

  On the other hand, when a large load is applied and forcibly bent, a remarkable bending wrinkle occurs in the bent portion. In such a state, even if the load is removed, the folded state cannot be restored to the original state. As a result, significant bending wrinkles are generated in the carrier tape, which hinders the removal of electronic components from the carrier tape.

  In addition, when the carrier tape is wound around the reel, the carrier tape is still wrinkled. When the electronic component is stored in the recess or when the electronic component is taken out from the recess, the effect of the curl The problem is that work efficiency is reduced.

  On the other hand, the bending part 21 provided in the carrier tape 2 according to the present invention hardly generates bending wrinkles and curling wrinkles even when folded at this part. For this reason, the carrier tape 2 can be easily folded in a small size, and can be easily returned to the state before the folding by pulling the folded carrier tape 2. Accordingly, the carrier tape 2 is a packaging material suitable for packaging in a state where the carrier tape 2 is folded in a zigzag shape. The packaging body 1 using such a carrier tape 2 is a rectangular parallelepiped piece as shown in FIG. When it accommodates in the packaging box 4, the clearance gap between the package 1 and the individual packaging box 4 can be remarkably reduced compared with the past. Further, even when an impact buffer member that fills the gap is used, the amount of use can be greatly reduced.

  In addition, although the bending part 21 exists intermittently for every predetermined number among the some space | interval parts 24, it is preferable that this number is constant in the carrier tape 2 whole. Thereby, since the package 1 can be bent at a constant interval, the package 1 after being bent can be collected into a rectangular parallelepiped shape.

  As described above, the groove 241 imparts flexibility to the bent portion 21, but the formation direction may be parallel to the fold line of the carrier tape 2. In FIG. 2, the groove 241 is formed over the entire width of the carrier tape 2, but may be formed only in a part of the width.

  Further, in the carrier tape 2 shown in FIG. 2, three grooves 241 are formed in one bent portion 21, but the number of the grooves 241 is not particularly limited, and the number of the bent portions 21 is increased as the number is increased. What is necessary is just to set suitably according to the material, thickness, etc. of the carrier tape 2 from a viewpoint that flexibility can be improved. As an example, it is preferable that it is 1-10 between the recessed part (pocket) 23 and the flat part between the recessed part (pocket) 23 adjacent to this, and it is more preferable that it is 3-5.

  The width of the groove 241 is preferably about 0.05 to 1.0 mm, more preferably about 0.1 to 0.5 mm.

  On the other hand, the cross-sectional shape of the groove 241 is not particularly limited, and may be a V shape, a U shape, a rectangular shape, or the like.

  Further, the depth of the groove 241 is appropriately set according to the thickness of the base material of the carrier tape 2, but is preferably about 10 to 80% of the thickness of the base material, and is about 20 to 50%. More preferably.

  Further, the groove 241 may be formed on any surface of the carrier tape 2, and when a plurality of grooves 241 are provided, the grooves 241 may be formed on different surfaces. Good.

  For example, all of the three grooves 241 shown in FIG. 2B are formed on the lower surface 20b side of the carrier tape 2, but the formation surface is not particularly limited, and may be as shown in FIG. Good.

  Each carrier tape 2 shown in FIG. 3 is the same as the carrier tape 2 shown in FIG. 2 except that the formation surface of the groove 241 is different.

  Among these, in the carrier tape 2 shown in FIG. 3A, all three grooves 241 are formed on the upper surface 20 a side of the carrier tape 2.

  On the other hand, in the carrier tape 2 shown in FIG. 3B, among the three grooves 241 arranged in parallel, the grooves 241 at both ends are formed on the upper surface 20a side of the carrier tape 2, and the remaining central groove 241 is the carrier groove 241. It is formed on the lower surface 20 b side of the tape 2.

  Further, in the carrier tape 2 shown in FIG. 3C, the central groove 241 is formed on the upper surface 20a side of the three grooves 241 arranged in parallel, and the remaining grooves 241 are the carrier grooves 241 on both sides. It is formed on the lower surface 20 b side of the tape 2.

  In the carrier tape 2 shown in FIG. 3 as described above, the same operation and effect as the carrier tape 2 shown in FIG. 2 can be obtained.

  Such a groove 241 can be formed by, for example, scanning while pressing a needle-shaped member in addition to pressing the forming die against the base material of the carrier tape 2.

  In addition to the groove 241, each bent portion 21 shown in FIG. 1 is provided with five through holes 242 that penetrate the carrier tape 2 in the thickness direction. By providing such a through hole 242, the substantial width of the carrier tape 2 is reduced by the amount of the through hole 242 in each bent portion 21, and the rigidity is accordingly reduced. As a result, the flexibility of each bending part 21 becomes higher.

  It is preferable that the substantial width of each bent portion 21 including the through hole 242 is about 1 to 70% with respect to the substantial width of each non-folded portion 22. By appropriately setting the length in the width direction of the through hole 242 so that the substantial width of each bent portion 21 falls within the above range, the bending ease of each bent portion 21 and the mechanical strength against tensile load Can be achieved. The substantial width of the bent portion 21 including the through holes 242 is obtained by subtracting the total width of the through holes 242 from the width of the carrier tape 2.

  Further, these five through holes 242 shown in FIG. 1 are arranged at equal intervals along the width direction of the bent portion 21. Thereby, the flexibility of the bending part 21 becomes high uniformly in the whole width direction.

  The shape of each through hole 242 in plan view is not limited to that shown in FIG. 1, and may be any shape such as a circle such as a perfect circle, an ellipse, or an ellipse, a polygon such as a triangle, a rhombus, or a parallelogram. May be. Moreover, the arrangement pattern of each through-hole 242 may be regular or irregular.

  Moreover, it is preferable that the length (distance in the longitudinal direction) of each bent portion 21 is longer than the length of the interval portion 24 located in the non-folded portion 22. Thereby, bending in each bending part 21 becomes easier.

  In addition, it is preferable that the length of each bending part 21 is the length more than the depth for two of the recessed parts 23. FIG. If it is such length, when the packaging body 1 is folded in a zigzag manner as shown in FIG. 3, the non-bending portions 22 adjacent in the vertical direction are parallel to each other without being inclined. As a result, the package 1 can be efficiently folded without a gap.

  The top cover tape 3 is bonded to the carrier tape 2 as described above so as to close the recess 23 in a state where the electronic component 10 is stored in the recess 23. Thereby, the package 1 is obtained.

  The top cover tape 3 is affixed to the carrier tape 2 by a method such as thermocompression bonding or adhesive bonding.

  As shown in FIG. 1, the top cover tape 3 is partially bonded to the center portion of the carrier tape 2 so as to exclude both ends of the carrier tape 2 in which the sprocket holes 29 are formed.

  Examples of the constituent material (material) of the top cover tape 3 include polyethylene and polyester (for example, polyethylene terephthalate).

  The packaging body 1 is accommodated in the individual packaging box 4 as described above, and the packaging body 1 accommodated in the individual packaging box 4 as described above is used when the electronic component 10 is mounted on a wiring board or the like. By pulling the upper end portion, it is fed out from above as shown in FIG. Therefore, a conventional apparatus for loading a reel or the like is not necessary, and for example, in the process of mounting the electronic component 10 on a wiring board, the production facility can be simplified.

  In the carrier tape 2, the same processing may be applied to any of the bent portions 21, but different processing may be performed between the bent portions 21.

  For example, the package 1 can be accommodated in the rectangular parallelepiped box 4 in a folded state as shown in FIG. 4, but in this state, the package 1 is folded with the bent portion 21a shown in FIG. The curvature radius is different between the portion 21b. The reason is that the radius of curvature of the bent portion 21a corresponds to the thickness of the electronic component 10 (the depth of the recess 23), whereas the radius of curvature of the bent portion 21b becomes extremely small. Therefore, for the carrier tape 2, even if it can be bent relatively easily if it is about the radius of curvature of the bent portion 21a, it cannot withstand bending at the radius of curvature of the bent portion 21b, and a remarkable bending wrinkle occurs. There is also a fear. Furthermore, the bending direction is different between the bent portion 21a and the bent portion 21b. Considering these points, it can be said that the processing applied to the bent portion 21 is preferably made different between the bent portion 21a and the bent portion 21b.

  Specifically, by changing at least one of the formation surface, the number of formations and the formation density of the grooves 241 and at least one of the formation number and the width of the through holes 242 between the bent portions 21a and the bent portions 21b, The bent part 21 can be suitable for the bent part 21a or the bent part 21b.

<< Second Embodiment >>
Next, a second embodiment of the carrier tape and package of the present invention will be described.

  FIG. 6 is a top view and a longitudinal sectional view showing a second embodiment of the package of the present invention. In FIG. 6, only the carrier tape is shown in the package. 6A is a top view, and FIG. 6B is a longitudinal sectional view.

  Hereinafter, although the second embodiment will be described, the description will focus on the differences from the first embodiment, and the description of the same matters will be omitted.

  The present embodiment is the same as the first embodiment except that each bent portion 21 is further provided with notches at both ends in the width direction of the carrier tape 2.

  That is, the carrier tape 2a shown in FIG. 6 has a groove 241 and a through hole 242 formed in each bent portion 21 as in the first embodiment. Further, the carrier tape 2a shown in FIG. 6 has notches 243 formed at both end portions in the width direction so as to open to the end surfaces.

  By adding the notch 243 in this way, the bending rigidity of each bent portion 21 is further reduced, the bendability of each bent portion 21 is further improved, and the occurrence of significant bending wrinkles due to bending is further reliably suppressed. can do.

  The notch 243 shown in FIG. 6 has a substantially rectangular shape in plan view, but the shape is not particularly limited, and a circle such as a perfect circle, an ellipse, or an ellipse, a triangle, a polygon such as a pentagon, etc. Any shape is possible.

  The carrier tape and package according to the second embodiment as described above exhibit the same operations and effects as those of the first embodiment.

<< Third Embodiment >>
Next, a third embodiment of the carrier tape and package of the present invention will be described.

  FIG. 7 is a top view and a longitudinal sectional view showing a third embodiment of the package of the present invention. In FIG. 7, only the carrier tape is shown in the package. 7A is a top view and FIG. 7B is a longitudinal sectional view. The upper side in FIG. 7B is referred to as “upper” and the lower side is referred to as “lower”.

  Hereinafter, the third embodiment will be described, but the description will focus on differences from the first embodiment and the second embodiment, and the description of the same matters will be omitted.

  The present embodiment is the same as the second embodiment except that each bent portion 21 is processed in a bellows shape.

  That is, in the carrier tape 2b shown in FIG. 7, instead of the groove 241 and the through hole 242, a sheet that is a base material of the carrier tape 2b of each bent portion 21 is formed in a bellows shape. As a result of such a bellows-shaped molding, the folding portions 21 are easy to be folded and the occurrence of significant bending wrinkles due to the folding is suppressed in each folding portion 21.

  Further, the bellows-like portion 244 shown in FIG. 7 is preferably formed so as to protrude toward the lower surface 20b side of the carrier tape 2b. Since the bellows-like portion 244 formed in this manner is formed so as to repeat the mountain fold and the valley fold, the thickness of the carrier tape 2b is increased by an amount corresponding to the height of the mountain or the depth of the valley. It has become. By forming the bellows-like portion 244 so as to protrude toward the lower surface 20b of the carrier tape 2b, the influence of the thickness of the bellows-like portion 244 on the total thickness of the carrier tape 2b can be minimized. it can. That is, since the concave portion 23 protrudes on the lower surface 20b side of the carrier tape 2b, if the thickness of the bellows-like portion 244 is less than the depth of the concave portion 23, the bellows-like portion 244 becomes the upper surface 20a or the lower surface of the carrier tape 2b. Protruding from 20b can be prevented. Thereby, when folded in a zigzag shape, the carrier tape 2b can be folded without a gap.

  The carrier tape and package according to the third embodiment as described above exhibit the same operations and effects as those of the first embodiment.

<< Fourth Embodiment >>
Next, a fourth embodiment of the carrier tape and package of the present invention will be described.

  FIG. 8 is a top view and a longitudinal sectional view showing a fourth embodiment of the package of the present invention. In FIG. 8, only the carrier tape is shown in the package. 8A is a top view and FIG. 8B is a longitudinal sectional view. The upper side in FIG. 8B is referred to as “upper” and the lower side is referred to as “lower”.

  Hereinafter, the fourth embodiment will be described, but the description will focus on the differences from the first to third embodiments, and description of similar matters will be omitted.

  The present embodiment is the same as the first embodiment except that the sheet serving as the base material of the carrier tape 2 is replaced with a thinner sheet in each bent portion 21.

  That is, in the carrier tape 2c shown in FIG. 8, the sheet | seat used as the base material of the carrier tape 2c of each bending part 21 is replaced by the connection sheet 245 which consists of a thinner sheet. In other words, the strip-shaped unfolded portions 22 are connected to each other via the connection sheet 245, whereby the carrier tape 2c is configured.

  The connecting sheet 245 is bonded to the lower surface of the carrier tape 2c so as to connect the two adjacent non-bent portions 22 to each other. A method for attaching the connection sheet 245 to the non-bent portion 22 is not particularly limited, and methods such as thermocompression bonding and adhesion using an adhesive can be used.

  The carrier tape and package according to the fourth embodiment as described above exhibit the same functions and effects as those of the first embodiment.

  As mentioned above, although the manufacturing method of the carrier tape and package of this invention was demonstrated based on embodiment of illustration, this invention is not limited to these, You may add arbitrary processes.

  Further, the carrier tape of the present invention may be a combination of two or more of the above embodiments. For example, a through hole may be added to the third embodiment or the fourth embodiment.

  Further, the article stored in the package 1 is not limited to the electronic component 10 and may be any article such as a machine part.

  In the fourth embodiment, the thickness of the connecting sheet 245 is thinner than that of the base material of the carrier tape 2b. However, the bending rigidity of the connecting sheet 245 is smaller than the bending rigidity of the non-bending portion 22. For example, the thicknesses may be the same, and in this case, the respective constituent materials (materials) may be made different so as to cause a difference in bending rigidity.

  Instead of using the connecting sheet 245, processing may be performed so as to partially reduce the thickness of the sheet serving as the base material of the carrier tape 2b at each bent portion 21.

The space | interval part 24 provided with the groove | channel 241 exists intermittently for every predetermined number.
Moreover, in each said embodiment, although the process of the groove | channel 241, the through-hole 231 grade | etc., Is not given to the space | interval part 24 located in the non-bending part 22, such a process is located in the non-bending part 22.
