Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a taping package in which electronic components are packaged with a tape-like packaging material and a method for manufacturing the same, and in particular, a taping package product in which a product name or an identification symbol is displayed on a tape-like packaging material by laser light irradiation printing, and a method for manufacturing the same. It relates to a manufacturing method.
[0002]
[Prior art]
Conventionally, surface-mounted electronic components such as resistors, capacitors, coils, varistors, thermistors, and diodes have been used for printed wiring boards of electric and electronic devices, but electronic components are mounted on the printed wiring board surface. In the case, from the viewpoint of automation of manufacturing, a form of a taping package 10 (also referred to as a series of electronic components) in which the electronic component 1 is packaged with a tape-like packaging material as shown in FIG. The product name and identification symbol of the component 1 are displayed only on the outer surface of the reel on which the taping package 10 has been wound.
[0003]
When surface-mounted electronic components first appeared, their dimensions were so large that it was possible to print the product name and identification symbol on the surface of each electronic component. As can be seen, devices are becoming lighter, thinner and smaller, and the surface-mounted electronic components used are becoming smaller, with widths, lengths, and thicknesses less than 1 mm each. The background is that it has become difficult to print the names and identification symbols of electronic components on the surface of the electronic components.
[0004]
The specific configuration of the taping packaged product is roughly divided into, as shown in FIG. 5, the upper and lower surfaces of a storage tape 11 having a recess (hole) 12 for storing the electronic component 1 and a feed hole 15 formed therein. There is a three-layer configuration in which cover tapes 13 and 14 cover each, or a two-layer configuration in which the upper surface of a storage tape (tape with embossment) having a bottomed recess for storing electronic components is covered with a cover tape.
[0005]
Known examples of the taping package include the following Patent Documents 1 and 2.
[0006]

[0015]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of a taping package and a method of manufacturing the same according to the present invention will be described with reference to the drawings.
[0016]
1 and 2 show a first embodiment of the present invention. FIG. 1 is a perspective view in which the bottom side of a taping package is directed upward, FIG. 2A is a front sectional view, and FIG. The figures are shown respectively. In these figures, a taping package 20 includes a storage tape 21 provided with a plurality of storage recesses 22 for storing the chip-shaped electronic components 1 one by one so as to be distributed in the length direction thereof. The cover tape 23 and the lower cover tape 24 are used as a tape-like packaging material. The storage tape 21 is provided with a plurality of feed holes 25 at an arrangement pitch correlated with the storage recess 22. Such a storage tape 21 is generally made of a material such as paper, polystyrene, or polyester. However, since the storage recess 22 described above is provided as a hole that penetrates in the thickness direction of the storage tape 21, The lower cover tape 24 is bonded (pressed) to the bottom surface side of the storage tape 21 so as to close the lower opening. After the electronic components 1 are stored one by one in the storage recess 22, the upper cover tape 23 is bonded (pressed) to the storage tape 21 so as to close the upper opening of the storage recess 22.
[0017]
In the present embodiment, as the lower cover tape 24, a material obtained by applying a resin laminating process using thin paper as a base material and performing an antistatic process is used. Then, after packaging the electronic component 1 with the tape-shaped wrapping material (the storage tape 21, the upper cover tape 23, and the lower cover tape 24), the electronic component stored by irradiating the lower cover tape 24 with a laser beam. Is printed at a position P indicated by a dashed line in the figure, for example. In this case, good visibility can be ensured by scoring (forming a branding) the thin paper as the base material of the lower cover tape 24 through the laminated resin. The resin lamination using the thin paper as the base material may be performed on one side or both sides of the thin paper. In the case of one side, the resin lamination is performed on the outer surface of the thin paper.
[0018]
An experimental example of laser beam irradiation printing is shown below.
(1) Conditions for the lower cover tape:
A thin paper having a weight of 14 gf / m ² per unit area is used as a base material, and a 20 μm-thick translucent polyethylene film laminated and subjected to antistatic processing is used. The lower cover tape is crimped to the storage tape.
(2) Conditions for laser beam irradiation printing:
Printing speed: 200 mm / sec Laser output: 18% (when the rated output of the laser printer is 100%)
Processing surface output: 2W (irradiation intensity on lower cover tape surface)
Focus: focus on lower cover tape Printing time: 0.28 seconds
FIG. 3 shows the state of printing in the above experimental example of laser light irradiation printing on the lower cover tape of the taping package. The lower cover tape is scorched (part of the thin paper is scorched) by laser light irradiation, and clear printing is obtained.
[0020]
When a laser printing apparatus is combined with a taping machine, a taping and packaging step of packaging electronic components with a tape-like packaging material and a printing step by laser beam irradiation can be performed almost simultaneously (linked). For example, in the order of the characteristic measurement process of the electronic component → the editing process → the taping and packaging process → the laser printing process → the winding process on the reel, or the characteristic measuring process → the taping and packaging process → the laser printing process → the winding process on the reel The steps can be executed in conjunction with each other in order.
[0021]
According to the first embodiment, the following effects can be obtained.
[0022]
(1) In the case where a small number of printed wiring boards are manufactured, for example, when a taping package is separated from a reel or cut off from a reel in a production line and used, a different part or a different kind of electronic part may be used. As a result, confusion can be prevented beforehand, and there is no need for rework, leading to a reduction in manufacturing costs.
[0023]
(2) There is an advantage that printing by laser beam irradiation can be controlled and managed by a simple computer system. Also, this is a method in which the surface of the tape-shaped packaging material is carbonized with laser light to express characters and symbols. The laser light focus is sharp, even small characters can be printed, and more complicated control is possible. Therefore, even small letters can be easily printed on the flat surface of the tape-shaped packaging material by laser light irradiation, making it possible to prevent the mixed use of different parts and different kinds of electronic parts beforehand, Can be maintained, and as a result, manufacturing costs can be reduced.
[0024]
(3) Since printing is performed by laser beam irradiation, the printing speed is high, and the process of measuring the characteristics of the electronic component → the taping / packaging process → the printing process → the winding process onto the reel can be linked, thereby contributing to an improvement in productivity.
[0025]
(4) Unlike the printing method using ink, there is a great secondary advantage that no industrial waste is involved because printing is performed by laser light irradiation.
[0026]
(5) By making the cover tape of the tape-shaped wrapping material resin-laminated on the thin paper, the thin paper can be scorched and printed by laser light irradiation, and the visibility is improved. Can be.
[0027]
FIG. 4 shows a second embodiment of the present invention. The taping package 20A includes a storage tape 21 provided with a plurality of storage recesses 22 for storing the electronic components 1 one by one so as to be distributed in a length direction thereof, a lower cover tape 24A, and an upper cover tape. 23 is used as a tape-shaped packaging material. Here, unlike the first embodiment, the lower cover tape 24A does not use a thin paper base material, has a structure of only a resin tape, and uses a paper mount tape as the storage tape 21.
[0028]
After wrapping the electronic component 1 with a tape-shaped wrapping material (the storage tape 21, the upper cover tape 23, and the lower cover tape 24A), the lower cover tape 24A is irradiated with a laser beam to obtain either the product name or the identification code. One or both are printed, for example, at a position P indicated by a dashed line in the figure. In this case, good visibility can be secured by scoring the surface of the mounting tape forming the storage tape 21 through the lower cover tape 24A.
[0029]
The other configuration is the same as that of the first embodiment, and the same operation and effect can be obtained.
[0030]
In each of the above embodiments, the storage tape, the upper cover tape, and the lower cover tape, the lower cover tape side of the tape-shaped packaging material was irradiated with laser light and printed on the bottom side of the tape-shaped packaging material. However, a similar effect can be obtained by a configuration in which laser light is irradiated on the upper cover tape side and printing is performed on the upper surface side of the tape-shaped packaging material. Further, the upper surface and the lower surface of the tape-shaped packaging material may be printed by laser beam irradiation.
[0031]
Further, in each of the above-described embodiments, the case of the tape-like packaging material having a three-layer structure including the storage tape, the upper cover tape, and the lower cover tape has been described. The present invention is also applicable to a case where a tape-like packaging material having a two-layer structure in which the upper surface of the formed storage tape (embossed tape) is covered with a cover tape is used.
[0032]
Although the embodiments of the present invention have been described above, it will be obvious to those skilled in the art that the present invention is not limited to the embodiments and various modifications and changes can be made within the scope of the claims.
[0033]

Since the product names and identification symbols of the electronic components stored in the packaging material are displayed, it is possible to prevent the mixed use of different components and different types of electronic components beforehand, eliminating the need for rework and reducing manufacturing costs. It leads to reduction.
[0035]
(2) Printing is performed by laser beam irradiation, and even small characters can be printed on a flat surface of a tape-shaped packaging material in a legible manner.
[0036]

Therefore, the laser beam focus is sharp, even small characters can be printed, and more complicated control is possible. Therefore, even small letters can be easily printed on the flat surface of the tape-shaped packaging material by laser light irradiation, making it possible to prevent the mixed use of different parts and different kinds of electronic parts beforehand, Can be maintained, and as a result, manufacturing costs can be reduced.
[0038]
(2) Since printing is performed by laser beam irradiation, the printing speed is high, and the process of measuring the characteristics of the electronic component → the taping / packaging process → the printing process → the winding process onto the reel can be linked, thereby contributing to an improvement in productivity.
[0039]
