Description

  The present invention relates to an electronic component package.

  Small electronic components such as electrical connectors and semiconductors are often handled in a form wound in a reel after being housed in a tape-like container and being used as an electronic component package at the time of shipment. For example, the tape-shaped container covers the embossed carrier tape with an embossed carrier tape in which a plurality of accommodating portions formed by embossing are arranged in the longitudinal direction of the tape, and a tape surface on the opening side of the accommodating portion. It consists of a cover tape. An electronic component package in which an electronic component is accommodated and formed in a container accommodating portion made of such an embossed carrier tape and a cover tape is handled as a product after being wound on a reel as described above. For example, when an electronic component is mounted on a substrate, the electronic component package as the product is set in an automatic mounting device or the like, and is sent out in the longitudinal direction of the tape at a constant speed, and the cover tape is peeled off. The electronic components are sequentially taken out from the housing portion, and the electronic components are automatically mounted on the substrate.

  Patent Document 1 discloses an electronic component package formed by accommodating electronic components in a container made of such an embossed carrier tape and a cover tape. 3A is a view of the electronic component package described in Patent Document 1 as viewed from above, and FIG. 3B is a cross-sectional view taken along the line BB in FIG. A taping component 11 as an electronic component package is formed by covering a top tape 13 as a cover tape on an upper surface of an embossed tape 12 containing an electronic component. As shown in FIG. 3A, the embossed tape 12 has a plurality of accommodating portions 14 formed by embossing arranged in the longitudinal direction of the tape. An electronic component (not shown) such as a container is accommodated. The top tape 13 covers the opening of the housing portion 14 and is thermocompression bonded to the upper surface of the embossed tape 12. The thermocompression bonding is performed by a seal portion 15 extending in the longitudinal direction at a position near both side edges of the top tape 13 as shown by a hatched region in FIG.

  4A and 4B are diagrams showing the taping component 11 when the electronic component is taken out. 4A is a view of the taping component 11 as viewed from above, and FIG. 4B is a schematic view of a BB cross section of FIG. When the electronic component is mounted on the substrate in the width direction, the taping component 11 is installed on an automatic surface mounting apparatus (not shown) while being wound on a reel, and one side end of the embossed tape 12 is mounted. An automatic feed pin (not shown) of the automatic surface mounting apparatus is engaged with an automatic feed hole 16 formed at a position close to the edge, and is fed forward (in the direction of arrow P) at a constant speed. At this time, the top tape 13 is peeled off from the upper surface of the embossed tape 12 by being continuously pulled by the automatic surface mounting device toward the rear oblique upper side, that is, in the direction of the arrow Q. Then, after the top tape 13 is peeled off, for example, the electronic component 18 in the housing portion 14 is sucked and taken out from above by a suction member 17 having a suction port at the lower end as shown in FIG. 4B. And surface-mounted on the board.

FIG. 5 is a diagram illustrating another example of the seal portion 15. The taping component 11 in FIG. 5 has basically the same form as the taping component 11 in FIGS. 3A and 3B, and only the position of the seal portion 15 is different. In the taping component 11 of FIG. 5, as shown as a hatched area, the seal portion 15 is formed between the accommodating portions 14 arranged in the longitudinal direction of the tape. Note that the usage pattern of the taping component 11 shown in FIG. 5 is the same as the usage pattern of the taping component 11 shown in FIGS. 3A and 3B described with reference to FIGS. 4A and 4B. It is.
JP-A-5-270565

  Since the seal portion 15 of the taping component 11 shown in FIG. 3 (A) is continuously formed in the longitudinal direction of the tape at both side edges of the top tape 13, the top seal 13 is peeled off. The magnitude of the peeling force, which is a necessary force, that is, the peeling strength is always constant, and the top seal 13 is not easily broken.

  However, since the seal portion 15 is not formed between the accommodating portions 14, the top tape 13 is separated from the embossed tape 12 between the accommodating portions 14, and a gap is formed between the top tape 13 and the embossed tape 12. As a result, for example, during handling in a state where the taping component 11 is wound on a reel, the electronic component may jump out of the accommodating portion 14 and enter the gap. In this case, since the electronic component is not in a fixed position, the automatic extraction of the electronic component is hindered. In recent years, electronic devices tend to be reduced in size and height, and electronic components used in electronic devices are becoming thinner. The problem of approaching is likely to occur.

  On the other hand, in the taping component 11 of FIG. 5, since the seal portions 15 indicated by diagonal lines are formed between the storage portions 14 arranged in the tape longitudinal direction, the positions corresponding to the storage portions 14 in the tape width direction, That is, the top tape 13 never leaves the embossed tape 12 at the center in the tape width direction. Accordingly, there is no gap between the top tape 13 and the embossed tape 12, so that the electronic component can be prevented from jumping out of the housing portion 14.

  However, the seal portion 15 of the taping component 11 of FIG. 5 is formed only between the accommodating portions 14 in the longitudinal direction of the tape, is not formed in the range of the accommodating portion 14, and is continuous in the longitudinal direction of the tape. Not. Therefore, when the top tape 13 is peeled from the embossed tape 12, the resistance force against the force pulling the top tape 13 is generated only in the seal portion 15 and not in the range corresponding to the accommodating portion 14. That is, the magnitude of the peel force that is originally required, that is, the peel strength, becomes discontinuous in the longitudinal direction and repeats abrupt changes in the same direction. However, since the automatic surface mounting apparatus continuously pulls the top tape 13, the top tape is formed at a portion where resistance to this force is generated, that is, at the front end of each seal portion 15, in other words, at the rear end of the accommodating portion 14. An excessive force acts on 13 rapidly, and the top tape 13 is easily broken.

  As described above, in the conventional electronic component package, it has been difficult to simultaneously achieve the two purposes of preventing the electronic component from jumping out of the housing portion and preventing the cover tape from breaking.

  In view of such circumstances, the present invention provides an electronic component packaging body capable of realizing both prevention of jumping out of an electronic component from a housing portion and prevention of breakage when the cover tape is peeled off. The task is to do.

  The electronic component package according to the present invention includes an embossed carrier tape having a plurality of receiving portions arranged in the tape longitudinal direction by embossing, and the housing in which the electronic components are housed. The embossed carrier tape is covered with the tape surface on the opening side of the portion, and the cover tape is fixed to a part of the tape surface.

  In such an electronic component packaging body, in the present invention, the fixing portion, which is a fixing portion between the embossed carrier tape and the cover tape, forms a band-like region extending in the longitudinal direction, and the accommodation on the tape surface of the embossed carrier tape is performed. It is characterized in that it is formed at both side positions and an intermediate position in the tape width direction in the outer peripheral edge area of the section.

  In the electronic component packaging body of the present invention, the fixing portions are formed at both side positions and an intermediate position in the tape width direction in the outer peripheral edge region of the housing portion. That is, since the plurality of fixing portions are located over the entire outer peripheral area of the housing portion, the cover tape is not separated from the tape surface of the embossed carrier tape in the outer peripheral region of the housing portion, and no gap is formed. Therefore, the electronic component does not jump out of the housing portion.

  The adhering portion forms a belt-like region extending in the tape longitudinal direction, and is formed at both side and intermediate positions in the tape width direction in the outer peripheral edge region of the accommodating portion. That is, since the plurality of fixing portions are continuously located in the longitudinal direction of the tape, a sudden change in the peel strength when the cover tape is peeled is reduced. In addition, as described above, the fixing portion has a strip shape extending in the longitudinal direction of the tape, that is, an elongated shape, and the total width of the fixing portion is small at any position in the longitudinal direction. The peeling force of is not so great.

  The fixing portion is preferably formed so that the total width of the plurality of fixing portions in the width direction of the embossed carrier tape is constant in the longitudinal direction of the embossed carrier tape. Thus, by making the sum of the widths of the plurality of fixing portions constant in the longitudinal direction of the tape, the peel strength at the time of peeling the cover tape can always be constant, so that the cover tape is difficult to break.

  It is preferable that the fixed part is formed so that the width of each fixed part in the width direction of the embossed carrier tape is the same. This is because the peeling force of the cover tape in the tape width direction becomes uniform.

  The fixing part may be formed by fusing the embossed carrier tape and the cover tape, or may be formed by bonding the embossed carrier tape and the cover tape.

  The present invention can also be applied to the case where the accommodating portions are arranged in the longitudinal direction of the embossed carrier tape in a plurality of rows in the width direction of the tape.

  In the present invention, since the adhering portions are formed at the both sides and the intermediate position in the tape width direction in the outer peripheral area of the housing part, the cover tape does not leave the tape surface of the embossed carrier tape in the outer peripheral area. As a result, the electronic component is prevented from jumping out of the housing portion, and always stays in the housing portion. As a result, the electronic component is fixed at a predetermined position when the electronic component is automatically taken out. Become. In addition, the fixing portion has a belt-like region extending in the longitudinal direction of the tape, and since the fixing portion is formed over the entire longitudinal direction, when the cover tape is peeled off, a sudden change in peeling strength is reduced, and the embossing is reduced. There is almost no shocking vibration to the carrier tape, the electronic component is stably in the housing portion, and the cover tape is not easily broken. In addition, since the entire width of the fixing portion can be small, the peeling force may be small.

<First embodiment>
FIG. 1A is a view of the electronic component package according to the first embodiment of the present invention as viewed from above. The electronic component package 1 includes a tape-shaped embossed carrier tape 2 (hereinafter referred to as “carrier tape 2”) in which a plurality of storage portions to be described later for storing electronic components are formed by embossing, and an opening of the storage portion. And a cover tape 3 that covers the carrier tape 2 on the side tape surface. As shown in FIG. 1, the carrier tape 2 has a width of a dimension D1, and the cover tape 3 has a width of a dimension D2 smaller than the dimension D1. The carrier tape 2 and the cover tape 3 are overlapped with each other in the entire width direction of the cover tape 3, but in FIG. 1 (A), the storage portion of the carrier tape 2 is shown by a solid line for easy understanding. It is.

  The carrier tape 2 has a plurality of receiving portions 4 which are formed so as to be immersed downward from the upper surface (in the drawing, in a direction sunk from the paper surface) in the longitudinal direction of the tape. The cover tape 3 covers the carrier tape 2 with an opening side tape surface, that is, an upper surface, of the housing portion 4 in which an electronic component (not shown) is housed, and a hatched area in FIG. Are fixed by a plurality of fixing portions 5 shown as. In the present embodiment, the fixing portion 5 is formed by fusing the carrier tape 2 and the cover tape 3. The means for forming the fixing portion 5 itself is not limited to fusion, and other known fixing means, for example, the fixing portion 5 may be formed by bonding the carrier tape 2 and the cover tape 3.

  Each fixing portion 5 forms a belt-like region extending in the tape longitudinal direction, and is formed with the same width (dimension in the direction perpendicular to the tape longitudinal direction). As shown in FIG. 1 (A), the adhering portion 5 is formed at both side and intermediate positions in the tape width direction in the outer peripheral edge region of the accommodating portion 4 on the upper surface of the carrier tape 2. In the present embodiment, two side edge adhering portions 5A are formed in the range of each accommodating portion 4 in the longitudinal direction of the tape near the both end edges of the cover tape 3 with the accommodating portion 4 interposed therebetween. Two intermediate fixing portions 5B are formed in an intermediate position in the tape width direction, that is, in a region between the storage portions 4 in the range between the storage portions 4 in FIG. As shown in FIG. 1A, the side edge fixing part 5A and the intermediate fixing part 5B have the same width, and the side edge fixing part 5A is formed slightly longer than the intermediate fixing part 5B. .

  For example, when electronic components are automatically mounted on a substrate, the electronic component package 1 according to the present embodiment is installed in an automatic mounting apparatus (not shown) while being wound around a reel. The electronic component packaging 1 installed in the automatic mounting apparatus is used for automatic feeding of the automatic mounting apparatus in the automatic feeding holes 6 formed at regular intervals in the longitudinal direction near the side edge of the carrier tape 2. A pin (not shown) is engaged and fed forward (in the direction of arrow P) at a constant speed.

  At this time, the cover tape 3 is pulled away from the upper surface of the carrier tape 2 by being continuously pulled by the automatic surface mounting device in the backward direction, that is, in the direction opposite to the arrow P. Then, after the cover tape 3 is peeled off, for example, an electronic component in the housing portion 4 is sucked and taken out from above by a suction member (not shown) and mounted at a predetermined position on the substrate.

  In the present embodiment, since the plurality of fixing portions 5 are formed over the entire outer peripheral area of the accommodating section 4, the cover tape 4 is not separated from the upper surface of the carrier tape 2 in the outer peripheral area, and no gap is generated. As a result, the electronic component is prevented from jumping out of the housing part 4 and always stays in the housing part 4. As a result, automatic removal of electronic components is stable and easy.

  As shown in FIG. 1A, in the longitudinal direction, the rear end portion of the side edge fixing portion 5A and the front end portion of the intermediate fixing portion 5B are in the same position, and the rear end portion of the intermediate fixing portion 5B. And the front end portion of the side edge adhering portion 5A are in the same position. In other words, the side edge fixing portions 5A and the intermediate fixing portions 5B are alternately and continuously formed in the longitudinal direction. Therefore, when the cover tape 3 is peeled off from the upper surface of the carrier tape 2, a resistance force against the force pulling the cover tape 3 is continuously generated.

  Further, the number of side edge fixing portions 5A formed in the range of the accommodating portion 4 in the longitudinal direction of the tape is the same as the number of intermediate fixing portions 5B formed in the range between the accommodating portions 4 in the longitudinal direction. Yes, the total width of the side edge fixing portions 5A and the total width of the intermediate fixing portions 5B are equal. That is, since the adhering portion 5 has a constant width in the tape longitudinal direction, the resistance to the force of pulling the cover tape 3 is also constant. Therefore, the magnitude of the peeling force required when peeling the cover tape 3, that is, the peeling strength is always constant without changing as shown in FIG. A strong force does not act abruptly and the cover tape 3 is not easily broken. Further, the adhering portion 5 has a strip shape extending in the longitudinal direction of the tape, that is, an elongated shape, and its width dimension is small, so that the peeling force when peeling the cover tape does not have to be very large.

  In the present embodiment, the peel strength is made constant by forming the fixed portions with the same width and positioning a fixed number of fixed portions in the longitudinal direction of the tape. However, the adhering portions do not necessarily have to be formed with the same width or a certain number in the longitudinal direction, and the total width of the adhering portions in the width direction of the carrier tape is the sum of the widths of the carrier tape. What is necessary is just to be formed so that it may become fixed in a longitudinal direction. For example, when the width dimension of the accommodating portion 4 is small, one intermediate fixing portion may be formed with a width equal to the total width of the side edge fixing portions. When the width dimension of the accommodating portion 4 is large, for example, intermediate fixing portions having a width that is half the width of the side edge fixing portion are formed by the number of times that of the side edge fixing portions. You may arrange | position by narrowing the space | interval of the said width direction of intermediate adhering parts by distributing to the whole direction. By forming the fixing portions in this way, the interval between the intermediate fixing portions is narrowed, so that the electronic components can be prevented from jumping out from the housing portion 4, and even if the number of intermediate fixing portions increases, Since the total width of the fixing portions is constant in the longitudinal direction, the peel strength is also constant, and the cover tape can be favorably prevented from breaking.

  In this embodiment, as shown in FIG. 1 (A), the accommodating portions are arranged in a line in the longitudinal direction of the tape, but as a modification, the accommodating portions form a plurality of rows in the width direction of the tape and the longitudinal direction May be arranged.

<Second embodiment>
This embodiment is different from the first embodiment in that many intermediate fixing portions are formed and side edge fixing portions are continuously formed in the longitudinal direction. Since the basic configuration of the electronic component package according to the present embodiment is the same as that of the first embodiment, the same parts as those of the first embodiment are denoted by the same reference numerals and description thereof is omitted.

  FIG. 2A is a view of the electronic component package according to the present embodiment as viewed from above. Of the fixing part 5 ′ of the electronic component packaging body 1 according to the present embodiment, the side edge fixing part 5 ′ A is continuously formed in the longitudinal direction of the tape at a position near both side edge parts of the cover tape 3. Yes. Further, the intermediate fixing part 5′B itself has the same shape as the intermediate fixing part 5B in the first embodiment, but in the present embodiment, three intermediate fixing parts 5B are formed between the accommodating parts 4. ing. That is, in the present embodiment, one intermediate fixing portion 5'B is formed more than the intermediate fixing portion 5B of the first embodiment. In the present embodiment, since the interval between the intermediate fixing portions in the tape width direction is narrowed by the number of intermediate fixing portions, compared to the first embodiment, the cover tape 2 and the carrier tape 3 It is difficult to form a gap between them, and the effect of preventing the electronic component from jumping out of the housing portion 4 is improved.

  In this embodiment, since the sum of the widths of the fixing portions is not equal between the range of the accommodating portion 4 in the tape longitudinal direction and the range between the accommodating portions 4, the resistance force generated when the cover tape 3 is peeled off is Accordingly, the peel strength is not constant in the longitudinal direction as shown in FIG. 2B. However, the total width of the fixing portions formed in the range between the accommodating portions in the tape longitudinal direction in this embodiment is smaller than that in the conventional electronic component package described with reference to FIG. Therefore, the required peeling force is small. Therefore, the degree of change in the peel strength in the present embodiment shown in FIG. 2B is also smaller than that in the conventional electronic component packaging body, and an excessive force acts on the cover tape 3 rapidly. Therefore, the cover tape 3 is not broken. Thus, according to the electronic component packaging body of this embodiment, the electronic component is effectively prevented from jumping out of the housing portion 4 and the cover tape 3 is prevented from being broken when the cover tape 3 is peeled off. be able to.

  In this embodiment, as shown in FIG. 2A, the accommodating portions are arranged in a line in the longitudinal direction of the tape. However, as a modification, the accommodating portions form a plurality of rows in the width direction of the tape. May be arranged.
