- the purpose is.
- One embodiment of the present disclosure includes a base material layer, a heat seal layer arranged on one surface side of the base material layer, and an intermediate layer arranged between the base material layer and the heat seal layer.
- a cover tape for packaging electronic components wherein the transmission image sharpness according to JIS K7374 is 30% or more with an optical comb having a width of 0.5 mm.
- One embodiment of the present disclosure includes a carrier tape having a plurality of storage portions for storing electronic components, electronic components stored in the storage portions, and the above-mentioned electronic component packaging arranged so as to cover the storage portions. Provided with a cover tape and a packaging.
- the position embodiment of the present disclosure includes a carrier tape having a plurality of storage portions for storing electronic components, and the above-mentioned cover tape for packaging electronic components used for covering the storage portions of the carrier tape. , Provides a set for packaging.
- the cover tape for packaging electronic components of the present disclosure when a CCD camera is used, the visibility of electronic components is improved to the extent that an image of electronic components is clearly reflected. Therefore, by using the cover tape for packaging electronic components or the packaging body of the present disclosure, the position, orientation, and angle of the electronic components can be reliably grasped, and the electronic components can be mounted with high accuracy and in a short time.
- the member when expressing the mode of arranging another member on a certain member, when simply expressing “above” or “below”, unless otherwise specified, the member is in contact with the certain member. Including the case where another member is arranged directly above or directly below, and the case where another member is arranged above or below a certain member via another member. Further, in the present specification, when expressing the mode of arranging another member on the surface of a certain member, when simply expressing "on the surface side" or “on the surface”, unless otherwise specified, the certain member is used. It includes both the case where another member is arranged directly above or directly below the member so as to be in contact with each other, and the case where another member is arranged above or below one member via another member.
- the cover tape for packaging electronic components and the packaging body of the present disclosure will be described in detail.
- the cover tape for packaging electronic components of the present disclosure includes a base material layer, a heat seal layer arranged on one surface side of the base material layer, and the base material layer and the heat seal layer.
- a cover tape for packaging electronic components having an intermediate layer arranged between the two, wherein the transmission image sharpness according to JIS K 7374 is 30% or more with an optical comb having a width of 0.5 mm. ..
- the haze value and total light transmittance of a cover tape for packaging electronic parts are used as indicators of visibility. It was used.
- the position, orientation, angle, etc. of the electronic component are confirmed by an inspection device such as a CCD camera in response to a request to perform the mounting process while confirming the position, orientation, and angle of the electronic component in the storage portion. In order to do so, it is necessary to make the amount of reflected light that reaches the CCD camera or the like from the electronic component larger than the amount of ambient light.
- the present inventors can analyze the position, orientation, angle, etc. of electronic components from an image obtained by a CCD camera or the like when a cover tape having only good haze value and total light transmittance is used. I found that it can be difficult.
- the present inventors considered using the transmission image sharpness as an index of the visibility of the cover tape. Furthermore, the present inventors have a wide (for example, 2.0 mm) transmission image sharpness of the optical comb of the mapability measuring device, which is insufficient as an index of visibility, and the width of the optical comb is 0.5 mm. It has been found that the following narrow transmission image sharpness is effective as a standard for visibility of electronic parts through a cover tape. When the width of the optical comb of the image quality measuring instrument is 2.0 mm and the transmitted image sharpness is 2.0 mm, a good value is shown even when the diffusion angle of the light transmitted through the cover tape for packaging electronic components is relatively wide.
- the reflected light of the electronic component transmitted through the tape does not actually determine the amount of light reaching the CCD camera or the like.
- the width of the optical comb is 0.5 mm and the transmission image sharpness is used, the amount of light in a region where the diffusion angle of light is narrow is evaluated. Therefore, the amount of reflected light actually reaching the CCD camera or the like is evaluated. Therefore, it is considered that it can be used as an index of whether or not the image is clearly captured when a CCD camera is used.
- the surface of the heat seal layer may change due to adhesion between the cover tapes, etc., depending on the environment during transportation. Specifically, the surface properties of the heat-sealed surface may change, causing unevenness in the transparency of the cover tape, resulting in a mottled pattern, which may lead to a problem such as deterioration of visibility.
- the cover tape has a high amount of reflected light from electronic components that actually reach the CCD camera or the like, the cover film has high visibility as a whole even if the surface surface of the heat seal surface changes. Therefore, the rate of change in visibility depending on the location can be lowered, and the occurrence of defects can be suppressed.
- FIG. 1 is a schematic cross-sectional view showing an example of the cover tape of the present disclosure.
- the cover tape 1 of the present disclosure includes a base material layer 2, a heat seal layer 3 arranged on one surface side of the base material layer 2 and a base material layer 2. It has an intermediate layer 4 arranged between the heat seal layer 3 and the heat seal layer 3.

- a cover tape 1 arranged so as to cover the portion 12 is provided.
- the cover tape 1 is heat-sealed on the carrier tape 11, and heat-sealing portions 3h are provided on both ends of the heat-sealing layer 3 of the cover tape 1 in a line shape with a predetermined width.
- the carrier tape 11 can have a feed hole 14.
- the transmission image sharpness is a value indicating how clear an image of an object that can be seen through plastic can be seen.
- the cover tape of the present disclosure has a transmission image sharpness of 30% or more, preferably 40% or more, particularly preferably 50, as measured by using an optical comb having a width of 0.5 mm in accordance with JIS K 7374. % Or more.
- the cover tape of the present disclosure is superior in visibility due to the clarity of the transmitted image as compared with the conventional cover tape, even if the surface property of the heat seal layer is changed by winding, the subsequent visibility occurs. It is less likely that sexual deterioration will occur.
- the upper limit of the transmission image sharpness measured using an optical comb having a width of 0.5 mm is not particularly limited, but is usually 70% or less.
- the transmission image sharpness according to JIS K7374 may be in the range of 20% or more, in particular, 30% to 70% with an optical comb having a width of 0.25 mm.
- the transmission image sharpness according to JIS K7374 is preferably 10% or more, particularly preferably in the range of 20% to 60% with an optical comb having a width of 0.125 mm.
- the transmitted image sharpness is determined by measuring the amount of light transmitted through the test piece of the cover tape through a moving optical comb and calculating it. Specifically, after attaching the test piece of the cover tape to the sample mounting base, the optical comb perpendicular to the ray axis of the transmitted light of the test piece is moved, the received light waveform is measured through the optical comb, and the light receiving waveform is measured on the ray axis.
- the maximum amount of light (M) when there is a transmissive part of the comb and the minimum amount of light (m) when there is a light-shielding part of the comb are read.

Abstract
Description
以下、本開示の電子部品包装用カバーテープおよび包装体について、詳細に説明する。
本開示の電子部品包装用カバーテープは、基材層と、前記基材層の一方の面側に配置されたヒートシール層と、前記基材層と前記ヒートシール層との間に配置された中間層と、を有する電子部品包装用カバーテープであって、JIS K 7374による透過像鮮明度が、幅0.5mmの光学櫛で30%以上であることを特徴とする。
本発明者らは、単に、ヘイズ値や全光線透過率だけが良好なカバーテープを用いた場合には、CCDカメラ等により得られる像から電子部品の位置、向きや角度等を解析することが困難な場合があることを見出した。
透過像鮮明度とは、プラスチックを透過して見える物体の像がどの程度鮮明に見えるかを示す値である。本開示のカバーテープは、JIS K 7374に準拠して、幅が0.5mmの光学櫛を用いて測定される透過像鮮明度が30%以上であり、好ましくは40%以上、特に好ましくは50%以上である。
C(n)={(M-m)/(M+m)}×100
ここで、C(n):光学櫛の幅n(mm)のときの透過像鮮明度(%)、M:光学櫛の幅n(mm)のときの最高光量、m:光学櫛の幅n(mm)のときの最低光量である。
本開示における基材層は、後述するヒートシール層や中間層を支持する層である。
基材層としては、0.5mmもしくは0.25mmの光学櫛を用いて測定されるカバーテープの透過像鮮明度を上記値以上とすることができ、かつ、保存および搬送時の外力に耐える機械的強度や、製造およびテーピング包装に耐える耐熱性等を有していれば、特に限定されるものではなく、種々の材料が適用できる。
具体的には、界面活性剤等の帯電防止材を樹脂中に練り込むことによって帯電防止処理を行い、帯電防止材を含む基材層とする態様が挙げられる。また、帯電防止処理方法として、2軸延伸フィルム等である基材層のヒートシール層側とは反対側の面に、必要に応じて、界面活性剤、ケイ素有機化合物、導電性カーボンブラック、導電性高分子、金属蒸着、金属酸化物などの導電性微粒子等を用いて、帯電防止層を最外層に設けることもできる。このように帯電防止処理を施すことにより、基材層の表面にゴミ、チリなどの付着防止あるいは他の面との接触による静電気の発生を防止することができる。
本開示におけるヒートシール層は、中間層の基材層と反対側の面側に配置される。ヒートシール層は、本開示のカバーテープを用いて包装体を製造する際に、キャリアテープに対してヒートシールすることにより、カバーテープとキャリアテープとが接着される。
上記粒径は、日機装株式会社 ナノトラック UPA-EX150を用い、動的光散乱法を用いて測定することができる。
なお、ここで50%粒径とは、粒径分布において、50%の粒子が含まれる粒径をいう。
粉体抵抗率=測定値×円柱の断面積/円柱の厚み
本開示のヒートシール層の表面抵抗率は、高抵抗率計(株式会社三菱化学アナリテック 高抵抗率計 ハイレスタ-UP)を用いて測定される。
しかしながら、分散剤の選定を誤ると、反って導電性微粒子の分散が不安定化し、コート剤が不均一(ゲル)化する場合や、塗膜の透明性(ヘイズ)が悪化する場合がある。そのため、分散剤の使用の有無に関わらず、安定した分散状態にすることが重要であり、そのようなコート剤を使用すると透明性が向上する。ただし、分散を進めすぎると、透明性が良くなる一方で、塗膜の導電性(表面抵抗率)が悪化する。即ち、ヒートシール層としては、導電性微粒子が適度に均一に分散した層であることが好ましい。
本開示においては、図1に示すように、基材層2およびヒートシール層3の間に中間層4が配置されている。中間層により、基材層およびヒートシール層の密着性を向上させることができる。さらに、中間層により、本開示のカバーテープをキャリアテープにヒートシールする際に、クッション性を向上させることができるために、より均一にヒートシール層に熱を与えることができる。さらに、中間層の選択によりカバーテープの透過像鮮明度の調整が容易となる。
本開示においては、例えば図3に示すように、基材層2と中間層4との間に、接着層5を有していてもよい。接着層を基材層に形成することで、基材層が接着力に乏しい場合であっても、基材層と中間層との間の密着性を向上させることができる。接着層としては、基材層、中間層に用いられる材料に応じて適宜選択すればよく、特に限定されるものではない。例えば、低密度ポリエチレン、密度0.915~0.940g/cm3のエチレン-α・オレフィン共重合体、ポリエチレンビニルアセテート共重合体、アイオノマー、ポリプロピレン、ポリブタジエン、ポリウレタン、ポリエステル、あるいは、それらの変性物のいずれかであるポリオレフィン、イソシアネート系、イミン系の接着剤等により形成することができ、厚さは0.2~60μm程度が好ましい。接着層は、基材層上に塗布あるいは押出し成形することができ、この接着層上に中間層をドライラミネーションあるいは押し出しラミネーションすることができる。なお、この層は上述した通り必要に応じて形成される層である。
本開示においては、例えば図3に示すように、上記ヒートシール層3と上記中間層4との間にプライマー層6を設けてもよい。特に、中間層4とヒートシール層3との間のデラミネーションを抑制することが要求される場合や、中間層4とヒートシール層3との接着性を向上させることが要求される場合に、好ましく適用することができる。
本開示のカバーテープは、上述の各層を積層してなるカバーテープにおける全光線透過率が70%以上であることが好ましく、特に、75%以上であることが好ましい。また、本開示においては、本開示のカバーテープのヘイズ値が、30%以下であることが好ましく、特に、25%以下であることが好ましい。
上記ヘイズ値および全光線透過率は、JIS K 7136およびJIS K 7361に準拠して測定した値である。
しかしながら、ヘイズ値及び全光線透過率のみを視認性の指標として用いても、透過像鮮明度のように光拡散の強さが考慮されないため、CCDカメラ等によるカメラ検査に必要とされる優れた視認性を得るカバーテープとすることができない。
本開示の包装体は、電子部品を収納する複数の収納部を有するキャリアテープと、上記収納部に収納された電子部品と、上記収納部を覆うように配置された、上述のカバーテープと、を備える。
以下、本開示の包装体の各構成について説明する。
本開示におけるカバーテープについては、上記「A.電子部品包装用カバーテープ」の項に記載したので、ここでの説明は省略する。
本開示におけるキャリアテープは、電子部品を収納する複数の収納部を有する部材である。
本開示の包装体に用いられる電子部品としては、特に限定されず、例えば、IC、抵抗、コンデンサ、インダクタ、トランジスタ、ダイオード、LED(発光ダイオード)、液晶、圧電素子レジスタ、フィルター、水晶発振子、水晶振動子、コネクタ、スイッチ、ボリュウム、リレー等が挙げられる。ICの形式についても、特に限定されない。
本開示の包装体は、電子部品の保管および搬送のために用いられる。電子部品は、包装体の状態で保管および搬送され、実装に供される。実装時には、カバーテープを剥離し、キャリアテープの収納部に収納されている電子部品を取り出し、基板等へ実装される。
本開示の包装体セットは、電子部品を収納する複数の収納部を有するキャリアテープと、前記キャリアテープの収納部を覆うために用いられる、上述した電子部品包装用カバーテープと、を有するものである。
また、本開示の包装体セットに用いられる電子部品包装用カバーテープは、上記「A.電子部品包装用カバーテープ」で説明したものと同様であるので、ここでの説明は省略する。
