Description

本発明は、例えば液晶パネル、ＰＤＰパネル、ＥＬパネル、ペアチップ実装などの電子部品と回路板、回路板同士を接着固定すると共に、両者の電極同士を電気的に接続する異方導電材を供給するための異方導電材テープに関し、特に異方導電材テープの巻き形態に関する。   The present invention supplies, for example, an anisotropic conductive material that bonds and fixes an electronic component such as a liquid crystal panel, a PDP panel, an EL panel, and a pair chip mounting, a circuit board, and circuit boards, and electrically connects both electrodes. In particular, the present invention relates to a winding form of the anisotropic conductive material tape.

異方導電材テープによる接続方法として、相対峙する電極間にフィルム状の接着剤である異方導電材を挟み、加熱加圧することにより接続を行うことがなされている。フィルム状の接着剤中には、電極間の導通を得る為の導電粒子が混合され、樹脂としては、熱可塑性樹脂、熱硬化性樹脂、または熱可塑性樹脂と熱硬化性樹脂の混合系、光硬化性樹脂が用いられている（例えば、特許文献１参照）。
また、導電粒子を含まず、樹脂のみからなる回路接続方法も知られている（例えば、特許文献２参照）。
樹脂の代表的なものには熱可塑性樹脂系としてスチレン樹脂系、ポリエステル樹脂系があり、また熱硬化性樹脂系としてはエポキシ樹脂系、シリコーン樹脂系、アクリル樹脂系が知られている。熱可塑性樹脂系、熱硬化性樹脂系共に接続する為に、加熱加圧が必要である。熱可塑性樹脂系では樹脂を流動させ被着体との密着力を得る為に、また熱硬化性樹脂系では更に樹脂の硬化反応を行う為である。近年、接続信頼性の面から、熱可塑性樹脂と熱硬化性樹脂の混合系、熱硬化性樹脂系が主流となっている。また、低温度で接続することのできる光硬化樹脂系も工業的に用いられ始めている。 As a connecting method using an anisotropic conductive material tape, an anisotropic conductive material that is a film-like adhesive is sandwiched between opposed electrodes and connected by heating and pressing. In the film adhesive, conductive particles for obtaining electrical conduction between the electrodes are mixed. As the resin, a thermoplastic resin, a thermosetting resin, a mixed system of a thermoplastic resin and a thermosetting resin, light A curable resin is used (see, for example, Patent Document 1).
In addition, a circuit connection method that does not include conductive particles and is made only of resin is also known (for example, see Patent Document 2).
Typical examples of the resin include a styrene resin system and a polyester resin system as thermoplastic resin systems, and epoxy resin systems, silicone resin systems, and acrylic resin systems are known as thermosetting resin systems. Heating and pressing are necessary to connect both the thermoplastic resin system and the thermosetting resin system. This is because the thermoplastic resin system allows the resin to flow to obtain adhesion to the adherend, and the thermosetting resin system further performs a resin curing reaction. In recent years, from the viewpoint of connection reliability, a mixed system of a thermoplastic resin and a thermosetting resin and a thermosetting resin system have become mainstream. Also, a photo-curing resin system that can be connected at a low temperature has begun to be used industrially.

近年、被接続体の反り及び伸びを防ぐために異方導電材の接続時の接続温度の低温化が要求されている。また、異方導電材の接続用途の拡大や液晶パネル、ＰＤＰパネル、ＥＬパネル、ベアチップ実装などの需要拡大に伴い接続時のタクトタイムの短時間化の要求が、強くなされるようになっている。
また、異方導電材の接続需要及び用途の拡大に伴い、短時間接続のみならず、生産性向上が要求されている。液晶パネル、ＰＤＰパネル、ＥＬパネル、ベアチップ実装などの需要拡大により、異方導電材テープの使用量は増加している。一方、液晶パネルの大画面及びＰＤＰパネルなど大画面フラットパネルの需要拡大に伴い、異方導電材テープの１枚のパネルに使用される使用量も増加した。従来、異方導電材テープは、断面が円形の芯材にフィルム状の接着剤を巻き重ねたリール形状で供給されており、リールの取り替え時間が生産性向上を妨げていた。
一方、液晶パネルの狭額縁化に伴い、異方導電材テープの狭幅化が進んでおり、従来の同一円芯状に巻いたリール形状では巻崩れが発生し、製造上の工程内歩留が悪化していた。
本発明は、上記欠点に鑑みなされたもので、リールの取り替え時間の間隔を長くし、また巻き崩れによる作業性の低下をなくして生産性の向上に寄与する異方導電材テープを提供することを目的とした。 In recent years, in order to prevent warpage and elongation of the connected body, it is required to lower the connection temperature when the anisotropic conductive material is connected. In addition, the demand for shortening the tact time at the time of connection has been made stronger with the expansion of applications for connecting anisotropic conductive materials and the growing demand for liquid crystal panels, PDP panels, EL panels, bare chip mounting, and the like. .
Further, along with the expansion of demand for connection of anisotropic conductive materials and applications, not only short-time connection but also improvement in productivity is required. With the growing demand for liquid crystal panels, PDP panels, EL panels, bare chip mounting, etc., the amount of anisotropic conductive material tape used is increasing. On the other hand, with the expansion of demand for large screen flat panels such as large screens of liquid crystal panels and PDP panels, the amount used for one panel of anisotropic conductive material tape has also increased. Conventionally, anisotropic conductive material tapes are supplied in the form of a reel in which a film-like adhesive is wound around a core having a circular cross section, and the replacement time of the reel has hindered productivity improvement.
On the other hand, along with the narrowing of the frame of the liquid crystal panel, the width of the anisotropic conductive material tape has been reduced, and the conventional reel shape wound around the same core has collapsed, resulting in an in-process yield. Was getting worse.
The present invention has been made in view of the above-mentioned drawbacks, and provides an anisotropic conductive material tape that contributes to improvement in productivity by increasing the interval between reel replacement times and eliminating workability degradation due to collapse. Aimed.

また、［２］フィルム状の接着剤の片面に基材フィルムを設けた２層構造の異方導電材である上記［１］に記載の異方導電材テープである。
また、［３］フィルム状の接着剤の両面に基材フィルムを設けた３層構造の異方導電材である上記［１］に記載の異方導電材テープである。
また、［４］基材フィルムの片面または両面が剥離処理された基材フィルムである上記［２］または上記［３］に記載の異方導電材テープである。
また、［５］フィルム状の接着剤の幅が、０．５〜５ｍｍである上記［１］ないし上記［４］のいずれかに記載の異方導電材テープである。
また、［６］基材フィルムの強度が、１２ｋｇ／ｍｍ２以上で、伸びが、６０〜２００％、厚みが、１００μｍ以下である上記［２］ないし上記［５］のいずれかに記載の異方導電材テープである。そして、基材フィルムは、有色透明または有色不透明に着色してあると基材フィルムと接着剤の判別が容易であり、また、巻きだし部の位置が容易となり、作業性が向上する。 The present invention is [1] An anisotropic conductive material tape, wherein an anisotropic conductive material made of a film-like adhesive is wound many times in the longitudinal direction of a core material.
[2] The anisotropic conductive material tape according to [1], which is an anisotropic conductive material having a two-layer structure in which a base film is provided on one side of a film-like adhesive.
[3] The anisotropic conductive material tape according to [1], which is an anisotropic conductive material having a three-layer structure in which a base film is provided on both surfaces of a film-like adhesive.
[4] The anisotropic conductive material tape according to the above [2] or [3], wherein the base film is a base film from which one side or both sides of the base film is peeled.
[5] The anisotropic conductive material tape according to any one of [1] to [4], wherein the film-like adhesive has a width of 0.5 to 5 mm.
[6] The difference according to any one of [2] to [5] above, wherein the strength of the base film is 12 kg / mm 2 or more, the elongation is 60 to 200%, and the thickness is 100 μm or less. This is a conductive tape. If the base film is colored transparent or colored opaque, it is easy to distinguish between the base film and the adhesive, and the position of the unwinding part becomes easy, thereby improving workability.

本発明によれば、被接続部材に対して良好な転写性（貼付け性）を有し、良好な接続信頼性を有し、そのことにより工程内における歩留を高め、さらに作業性をも向上した、従来より長尺の異方導電材テープの供給が可能であり、生産性、作業性が向上する。   According to the present invention, it has good transferability (sticking property) to the connected member, has good connection reliability, thereby increasing the yield in the process and further improving workability. Thus, it is possible to supply an anisotropic conductive material tape that is longer than conventional ones, and productivity and workability are improved.

本発明の一実施形態は、図１及び図２に示したように、糸巻き状にフィルム状の接着剤２と両面を剥離処理した基材フィルム１の２層構造あるいはフィルム状の接着剤２と接着剤面を剥離処理した２種の基材５、６の３層構造からなる異方導電材テープの供給形態である。
異方導電材テープを側板３の付いた芯材（巻芯）４の長手方向に多数回巻き積層して糸巻き状に巻くことにより、巻崩れのない、長尺の異方導電材テープの供給が可能あり、生産性の向上が可能となる。
基材フィルム１、５、６の引張り強度は、１２ｋｇ／ｍｍ２以上、基材フィルム１、５、６の破断伸びは６０〜２００％にすることにより、基材フィルムが強度を持ち、伸びが小さいため、異方導電材であるフィルム状接着剤２を接続部材に転写する前のプロセスにおいて、フィルム状接着剤２が伸びたり、厚みが薄くなったり、幅が細くなったりすることを防止できる。また、基材フィルム１、５、６の厚みはハンドリング及び環境面から考えると１００μｍ以下が望ましい。
薄いと上記効果に劣るようになるので０．５μｍ以上とするのが好ましい。フィルム状の接着材である異方導電材が、粘着性がなく、ブロッキング現象を示さないものであればフィルム状の接着材を基材フィルム無しで単独で糸巻き状に巻くことができる。
基材フィルムの剥離処理は、シリコンまたはフッ素処理を行うことにより容易に行うことができ、基材フィルムの片面にのみ剥離処理を行うと、基材フィルムの表裏に離型性に差を設けることができ、基材フィルムに対する背面転写を防止することができる。また、基材フィルムの両面に剥離処理を行うと、フィルム状接着剤面はシリコン及びフッ素処理を行い、剥離性を有するものとする。 As shown in FIGS. 1 and 2, one embodiment of the present invention includes a two-layer structure of a film-like adhesive 2 and a base film 1 that has been peeled on both sides, or a film-like adhesive 2, as shown in FIGS. This is a supply form of an anisotropic conductive material tape having a three-layer structure of two types of base materials 5 and 6 having the adhesive surface peel-treated.
Supply of a long anisotropic conductive material tape without winding collapse by winding an anisotropic conductive material tape many times in the longitudinal direction of the core material (winding core) 4 with the side plate 3 and winding it in a bobbin shape. It is possible to improve productivity.
The base film 1, 5, 6 has a tensile strength of 12 kg / mm 2 or more, and the base film 1, 5, 6 has an elongation at break of 60 to 200%. Since it is small, it is possible to prevent the film-like adhesive 2 from being stretched, thinned, or thinned in the process before transferring the film-like adhesive 2 that is an anisotropic conductive material to the connecting member. . Further, the thickness of the base film 1, 5, 6 is preferably 100 μm or less in view of handling and environmental aspects.
If it is thin, the above effect will be inferior, so 0.5 μm or more is preferable. If the anisotropic conductive material that is a film-like adhesive is not sticky and does not exhibit a blocking phenomenon, the film-like adhesive can be wound alone in a bobbin shape without a base film.
The release treatment of the base film can be easily performed by performing silicon or fluorine treatment. When the release treatment is performed only on one side of the base film, a difference in the releasability is provided between the front and back of the base film. The back transfer to the base film can be prevented. Moreover, when a peeling process is performed on both surfaces of the base film, the film-like adhesive surface is subjected to silicon and fluorine treatment to have peelability.

図２は、図１の基材フィルムを２種類とし、異方導電材を含み、３層構造からなる異方導電材テープの供給形態を説明する模式図である。

本発明に用いられるフィルム状の接着剤２は、高信頼性を有する熱硬化性樹脂系であるエポキシ樹脂系、接着剤の低応力化を図り、接着剤の相溶性に効果のあるシリコーン樹脂系、これらより更に低温度・短時間で接続することが可能なラジカル系は主にアクリル系接着剤を使用するが、これらに制限するものではない。
さらに、本発明の異方導電材テープに用いられる基材フィルムは、強度及び異方導電材を構成する接着剤の剥離性の面からシリコン及びフッ素剥離処理したＰＰ（ポリプロピレン）、ＯＰＰ（延伸ポリプロピレン）、ＰＥＴ（ポリエチレンテレフタレート）などを用いるが、これらに制限するものではない。
異方導電材を用いた接続は、タクトタイムの向上が求められており、異方導電材の転写性が要求されている。異方導電材テープを側板３の付いた芯材（巻芯）４に糸巻き状に巻くことにより、異方導電材テープの取り替え時間の間隔を長くすることができ、巻崩れのない、長尺の異方導電材テープの供給が可能であり、生産性の向上が可能となる。
図２は、基材フィルムを２種類とし、異方導電材を含み、３層構造からなる異方導電材テープの供給形態であり、接着剤である異方導電材が柔らかい場合、巻芯側の次の基材フィルムによる接着剤の変形を防止することができる。 The present invention will be described more specifically with reference to the drawings.
FIG. 1 is a schematic view for explaining one embodiment of a supply form of an anisotropic conductive material tape having a two-layer structure comprising a film-like adhesive of the present invention and a base film having both surfaces peeled.
FIG. 2 is a schematic diagram illustrating a supply form of an anisotropic conductive material tape having two types of base film of FIG. 1 and including an anisotropic conductive material and having a three-layer structure.
The anisotropic conductive material tape of the present invention comprises a film-like adhesive 2 which is an anisotropic conductive material applied on a base film 1 and is used for connecting highly refined electronic components. In order to prevent foreign matter and contamination, a structure in which the base film 1 is outside the adhesive is shown.
The film-like adhesive 2 used in the present invention includes a highly reliable epoxy resin system that is a thermosetting resin system, a silicone resin system that is effective in reducing the adhesive stress and is effective in adhesive compatibility. The radical system that can be connected at a lower temperature and in a shorter time than these mainly uses an acrylic adhesive, but is not limited thereto.
Furthermore, the base film used for the anisotropic conductive material tape of the present invention is made of PP (polypropylene) or OPP (stretched polypropylene) that has been subjected to silicon and fluorine peeling treatment in terms of strength and peelability of the adhesive constituting the anisotropic conductive material. ), PET (polyethylene terephthalate), and the like are used, but are not limited thereto.
The connection using the anisotropic conductive material is required to improve the tact time, and the transfer property of the anisotropic conductive material is required. By winding the anisotropic conductive material tape around the core material (winding core) 4 with the side plate 3 in a bobbin-like manner, the interval of the anisotropic conductive material tape replacement time can be lengthened, and there is no collapse. The anisotropic conductive material tape can be supplied, and the productivity can be improved.
FIG. 2 is a supply form of an anisotropic conductive material tape comprising two types of base films, including an anisotropic conductive material, and having a three-layer structure. When the anisotropic conductive material as an adhesive is soft, the core side The deformation of the adhesive by the next base film can be prevented.

さらに、基材フィルムの物性値である基材フィルムの引張り強度は、１２ｋｇ／ｍｍ２以上で、基材フィルムの破断伸びは、６０〜２００％にすることにより、基材フィルムに物理的強度が得られ、フィルム状の接着剤の伸びに伴う、薄膜化、幅方向に細くなることを防ぐことが可能である。また、基材の厚みは１００μｍ以下にすることにより、ハンドリング及び環境面での対応が可能である。 Furthermore, the tensile strength of the base film, which is a physical property value of the base film, is 12 kg / mm 2 or more, and the base film has a physical strength of 60% to 200% by breaking elongation. As a result, it is possible to prevent thinning and thinning in the width direction accompanying the elongation of the film-like adhesive. Further, when the thickness of the substrate is 100 μm or less, handling and environmental measures can be taken.
