Description

【0001】
【発明の属する技術分野】
本発明は、電子部品と回路基板、又は回路基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接着剤テープに関し、特にリール状に巻かれた接着剤テープの接続方法、及び接着剤テープ接続体に関する。
【0002】
【従来の技術】
一般に、液晶パネル、PDP(プラズマディスプレイパネル)、EL(蛍光ディスプレイ)パネル、ペアチップ実装などの電子部品と回路基板、回路基板同士を接着固定し、両者の電極同士を電気的に接続する方法として、接着剤テープが用いられている。
特許文献1には、基材に接着剤が塗布された接着剤テープをリール状に巻き取ったものが開示されている。
この種の従来の接着剤テープは、幅が1〜3mm程度であり、リールに巻き取るテープの長さは50m程度である。
接着剤テープを接着装置に装着する場合、接着剤テープのリール(以下、単に「接着剤リールという」)を接着装置に取り付け、接着剤テープの始端部を引き出して、巻取りリールに取り付ける。そして、接着剤リールから巻き出された接着剤テープの基材側から加熱加圧ヘッドで接着剤を圧着回路基板等に圧着し、残った基材を巻取りリールに巻き取っている。
そして、接着剤リールの接着剤テープが終了すると、終了したリールと、基材を巻き取った巻取りリールを外し、新たな巻取りリールと新たな接着剤リールを接着装置に装着し、接着剤テープの始端を巻取りリールに取り付けている。

【発明が解決しようとする課題】
しかし、近年のPDP等におけるパネル画面の大型化にともない回路基板の接着面積が増大し、一度に使用する接着剤の使用量が増加してきた。また、接着剤の用途も拡大したため、接着剤の使用量が増加してきた。このため、電子機器の製造工場では、接着剤リールの交換頻度が多くなり、接着剤リールの交換に手間がかかるため電子機器の生産効率の向上が図れないという問題がある。
かかる問題に対して、リールに巻き取る接着剤テープの巻き数を多くすることで、1リール当りの接着剤量を増やし、リールの交換頻度を低減することが考えられるが、接着剤テープのテープ幅が1〜3mmと狭いため、巻き数を多くすると巻き崩れが生じるおそれがある。また、巻き数を多くするとテープ状に巻いた接着剤テープに作用する圧力が高くなり接着剤がテープの両幅から染み出してブロッキングの原因になるおそれがある。
更に、接着剤テープの巻き数を増やすと、リールの径寸法も大きくなり、既存の接着装置に装着し難く、既存の接着装置が使用できなくなるおそれがある。
そこで、本発明は、接着剤リールの交換が簡単にでき、電子機器の生産効率の向上を図ることができる接着剤テープの接続方法、及びその接続方法により製造される接着剤テープ接続体の提供を目的とする。
【0005】
【課題を解決するための手段】
前記課題を解決するために、請求項1に記載された発明は、電極接続用の接着剤が基材に塗布された、一方のリールに巻いた一方の接着剤テープと他方のリールに巻いた他方の接着剤テープとを接続する接着剤テープの接続方法であって、一方の接着剤テープの終端部と、他方の接着剤テープの始端部とを、いずれか一方の基材面に他方の接着剤面を重ね合わせ、両者の重ね合わせ長さを接着剤テープの幅の2倍乃至50倍の範囲として、両者を加熱圧着して接続することを特徴とする。
この請求項1に記載の発明では、接着剤テープの接着剤を利用して終了した接着剤テープの終端部と、新たに装着する接着剤テープの始端部とを接着して、接着剤リールの交換を行うので、接着装置への新たな接着剤リールの装着が簡単にできる。また、新たな接着剤リールの交換毎に巻取りリールの交換や新規接着剤の始端を巻取りリールに取り付ける作業が必要ないので、新しい接着剤リールの交換時間が少なくて済み、電子機器の生産効率が高まる。
重ね合わせ部分の長さを接着剤テープの幅の2倍乃至50倍としているのは、2倍よりも少ないと充分な接続強度が得られず、50倍よりも大きいと接続部分に使用する接着剤が多くなりすぎて、接着剤が無駄になるからである。
接続部分の加熱圧着は、接着剤リールを装着する接着装置の加熱加圧ヘッドを用いれば、接着装置を合理的に利用することができる。
接着剤は、絶縁性接着剤中に導電粒子を分散した異方導電性接着剤であってもよいし、絶縁性接着剤のみであってもよいし、それらの接着剤中に絶縁性のスペーサ粒子を分散したものであってもよい。
【0006】
請求項2に記載された発明は、電極接続用の接着剤が基材に塗布された、一方のリールに巻いた一方の接着剤テープと他方のリールに巻いた他方の接着剤テープとを接続する接着剤テープの接続方法であって、一方の接着剤テープの終端部を接着剤が対面する方向に折り曲げ、他方の接着剤テープの始端部を接着剤が対面する方向に折り曲げ、両者の折り曲げ部分を互いに係止して重ね合わせ且つ両者の接着剤面を対面させて、重ね合わせ部分を加熱圧着することを特徴とする。
この請求項2に記載の発明によれば、請求項1に記載の発明と同様な作用効果を奏するとともに、一方の接着剤テープの終端部と他方の接着剤テープの始端部とを互いに鉤状にして係止するとともに、両者は接着剤面を互いに接続するので、接続強度が高い。
【0007】
請求項3に記載された発明は、請求項1又は請求項2に記載された発明において、一方の接着剤テープの終端部にはエンドマークが付されていることを特徴とする。
この請求項3に記載の発明によれば、請求項1又は請求項2記載の発明と同様な作用効果を奏するとともに、一方の接着剤テープの終端部はエンドマーク部分で行うことができるので、接続作業をする部分が解りやすく且つ必要最小限の位置で接続できるので接着剤テープの無駄を防止できる。また、エンドマーク部分を自動で検知でき、その検知信号により装置を制御したり、警報を発するようにすると作業効率を高めることができる。
【0008】
請求項4に記載された発明は、請求項1〜3のいずれか一項に記載の発明において、一方の接着剤テープと他方の接着剤テープとの重ね合わせ部分を、凹凸を形成した一方の金型と、これに噛み合う他方の金型とで挟んで加熱圧着することを特徴とする。
この請求項4に記載の発明によれば、請求項1〜3のいずれか一項に記載の発明と同様な作用効果を奏するとともに、接続部分に凹凸を形成することより、接続面積を広くできるとともに、凹凸部の係合により接着剤テープの引張り方向(長手方向)の接続強度を高めることができる。
【0009】
請求項5に記載された発明は、請求項1〜3のいずれか一項に記載の発明において、一方の接着剤テープと他方の接着剤テープとの重ね合わせ部分に貫通穴を形成した後、重ね合わせ部分を加熱圧着することを特徴とする。
この請求項5に記載の発明によれば、請求項1〜3のいずれか一項に記載の発明と同様な作用効果を奏するとともに、接続部分に貫通孔を形成することにより、貫通孔の内周に接着剤が染み出して、接着剤による接着面積が増えるので、更に接続強度を高めることができる。
請求項6に記載された発明は、電極接続用の接着剤が基材に塗布された、一方のリールに巻いた一方の接着剤テープの終端部と、他方のリールに巻いた他方の接着剤テープの始端部とを接続する接続部分を有する接着剤テープ接続体であって、上記接続部分は、一方の接着剤テープの終端部と、他方の接着剤テープの始端部とを、いずれか一方の基材面に他方の接着剤面を重ね合わせ、両者の重ね合わせ長さを接着剤テープの幅の2倍乃至50倍の範囲として、両者を加熱圧着して接続することにより設けられていることを特徴とする。
請求項7に記載された発明は、電極接続用の接着剤が基材に塗布された、一方のリールに巻いた一方の接着剤テープの終端部と、他方のリールに巻いた他方の接着剤テープの始端部とを接続する接続部分を有する接着剤テープ接続体であって、上記接続部分は、一方の接着剤テープの終端部を接着剤が対面する方向に折り曲げ、他方の接着剤テープの始端部を接着剤が対面する方向に折り曲げ、両者の折り曲げ部分を互いに係止して重ね合わせ且つ両者の接着剤面を対面させて、重ね合わせ部分を加熱圧着することにより設けられていることを特徴とする。
【0010】
【発明の実施の形態】
以下に添付図面を参照しながら本発明の実施の形態について説明するが、まず図1〜図4を参照して本発明の第1実施の形態について説明する。図1は第1実施の形態にかかる接着剤テープの接続方法を示す図であり、(a)は接着剤リール同士の接続を示す斜視図であり、(b)は(a)における接続部分の接続方法を示す斜視図であり、図2は接着装置における接着剤の圧着工程を示す概略図であり、図3は回路基板同士の接着を示す断面図であり、図4は接着剤テープの製造方法を示す工程図である。
【0011】
接着剤テープ1はリール3、3aにそれぞれ巻かれており、各リール3、3aには巻き芯5と接着剤テープ1の両幅側に配置した側板7とが設けられている。
本実施の形態では、接着剤テープ1は長さが約50mであり、幅Wが約3mmである。
接着剤テープ1は、基材9と、基材9の一側面に塗布された接着剤11とから構成されている。
基材9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OPP(延伸ポリプロピレン)、ポリテトラフルオロエチレン、シリコーン処理した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。
【0012】
接着剤11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、ホットメルト系が用いられている。かかる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、ビニルエステル系樹脂、アクリル樹脂系、シリコーン樹脂系が用いられる。
接着剤11には、導電粒子13が分散されている。導電粒子13としては、Au,Ag,Pt,Ni,Cu,W,Sb、Sn,はんだなどの金属粒子やカーボン、黒鉛などがあり、これら及び非導電性のガラス、セラミックス、プラスチック等の高分子核材等に、前記した導電層を被覆等により形成したものでもよい。
さらに前記したような導電粒子を絶縁層で被覆してなる絶縁被覆粒子や、導電粒子と絶縁粒子の併用等も適用可能である。はんだ等の熱溶融金属や、プラスチック等の高分子核材に導電層を形成したものは、加熱加圧もしくは加圧により変形性を有し、接続後の電極間の距離が減少し、接続時に回路との接触面積が増加し信頼性が向上するので好ましい。特に高分子類を核とした場合、はんだのように融点を示さないので軟化の状態を接続温度で広く制御でき、電極の厚みや平坦性のばらつきに対応し易い接続部材が得られるのでより好ましい。
【0013】
次に、本実施の形態にかかる接着剤テープの使用方法について説明する。図2に示すように、接着装置15に接着剤テープ1のリール3aと、巻取りリール17とを装着し、リール3aに巻いた接着剤テープ1の先端を巻取りリール7に取り付け、接着剤テープ1を繰り出す(図2中矢印E)。そして、回路基板21上に接着剤テープ1を配置して、両リール3a、17間に配置された加熱加圧ヘッド19で接着剤テープ1を基材9側から圧接し、接着剤11を回路基板21に圧着する。その後、基材9を巻取りリール17に巻き取る。
上記の圧着後(仮接続)、回路基板21の電極と配線回路(電子部品)23の電極を位置合わせして本接続する。本接続は、図3に示すように、回路基板21に圧着された接着剤11に配線回路(又は電子部品)23を配置して、必要によりクッション材として、例えば、ポリテトラフルオロエチレン材24を介して加熱加圧ヘッド19により配線回路23を回路基板21に加熱加圧する。これにより回路基板21の電極21aと配線回路23との電極23aを接続する。
【0014】
本実施の形態による接着剤テープ1を用いたPDPは、そのサイズが大きくなっており、PDPの周囲全体に亘り圧着する場合があり、接続部分が多く、接着剤11は一度に用いる接着剤11の使用量が従来に比較して格段に多くなる。したがって、リール3aに巻いた接着剤テープ1の使用量も多くなり、リール3aに巻いた接着剤テープ1は比較的短時間で巻取りリール17に巻き取られて、リール3aに巻かれた接着剤テープ1のエンドマーク28が露出される(図1参照)。
【0015】
本発明の接着剤テープの接続方法は、(a)巻取りリール17をそのまま使用し、使用済みの接着剤テープ1の巻きが残り少なくなった接着剤テープを交換し、新たな接着剤テープと巻取りリール17を接続する場合と、(b)巻取りリール17として使用済みの接着剤テープ1の巻きが残り少なくなった接着剤テープを使用し、新たな接着剤テープと巻きが残り少なくなった接着剤テープを接続する場合がある。
(b)の場合、図1に示すように、リール3aの接着剤テープ1にエンドマーク28が露出したところで、リール3aを新たな接着剤リール3と交換するため、リール3aの接着剤テープ(一方の接着剤テープ)1の終端部30と、新たな接着剤リール3に巻かれた接着剤テープ(他方の接着剤テープ)の始端部32とを接続する。(図1(a)参照)
この接着剤テープ1の接続は、図1(b)に示すように、接着剤リール3aの接着剤テープ1の終端部30と、新たな接着剤リール3の接着剤テープ1の始端部32とについて、終端部30の基材9面に始端部32の接着剤11を重ね合わせる。両者の重ね合わせ長さHを接着剤テープ1の幅Wの約2.5として、テーブル36に置き、接着装置15の加熱加圧ヘッド19で加熱加圧して接着する。
これにより、使用済みのリール3aに巻かれた接着剤テープ1と、新たなリール3に巻かれた接着剤テープ1とが接続される。次に、使用済みのリール3aと新たなリール3を入れ替えて、新たなリール3を接着装置15に装着する。したがって、巻取りリール17に接着剤テープを装着する作業が必要ない。
この実施の形態では、加熱加圧ヘッド19を利用しているので、接着剤同士の圧着用器具を別途用いることなく、接着剤1が巻かれたリール3、3aの交換ができる。
【0016】
(a)の巻取りリール17をそのまま使用し、使用済みの接着剤テープ1の巻きが残り少なくなった接着剤テープを新たな接着剤テープと交換し、新たな接着剤テープと巻取りリール17を接続する場合は、使用済みリール3aの接着剤テープ1のエンドマーク28が露出したときに接着剤テープ1のエンドマーク28付近を切断し、巻取りリール17側に残った接着剤テープの終端部30と新たな接着剤リール3の接着剤テープ1の始端部32を重ね合わせる。そして、両者の重ね合わせ部分を接着装置15の加熱加圧ヘッド19で加熱加圧して接着する。
巻取りリール17では基材9だけを巻き取っているので、接着剤リールの数本分を巻き取ることができるので、巻取りリール17の交換回数を少なくすることができ、作業効率が良い。
【0017】
ここで、図4を参照して本実施の形態にかかる接着剤テープ1の製造方法について説明する。
巻出機25から巻きだされた基材(セパレータ)にコーター27により、樹脂と導電粒子13が混合された接着剤11を塗布し、乾燥炉29で乾燥した後、巻取機31で原反を巻き取る。巻き取られた接着剤テープの原反は、スリッタ33により所定幅に切断されて巻き芯に巻き取れられた後、巻き芯に側板7,7が両側から装着されて、あるいは、側板付巻き芯に巻き取られ、除湿材とともに梱包され、好ましくは、低温(−5℃〜−10℃)に管理されて出荷される。
【0018】
次に、本発明の他の実施の形態について説明するが、以下に説明する実施の形態では上述した実施の形態と同一の部分には同一の符合を付することによりその部分の詳細な説明を省略し、以下では上述した実施の形態と異なる点を主に説明する。
図5に示す第2実施の形態では、接着剤テープ1の重ね合わせ部分34を、表面にあるぎざぎざ(凹凸)が互いに嵌合する一方の金型41と他方の金型43とで挟持し、重ね合わせ部分34に凹凸45を形成する。このように凹凸45を形成することにより、重ね合わせ部分34における接着面積を増やすことができ、且つ重ね合わせ部分34の凹凸45の係合により引張り方向(接着剤テープの長手方向)の強度を高くできる。凹凸形成の際に、接着剤11が流動して重ね合わせ部分の端面同士が接着剤により接着され、さらに、重ね合わせ部分34の引張り方向の強度が高まる。
【0019】
図6に示す第3実施の形態では、新しい接着剤1が巻かれたリール3の始端部32を略V字形状に折り曲げ、使用済みリール3aに巻かれた接着剤テープ1の終端部30も略V字形状に折り曲げて、両者を鉤状にして接着剤11を対面させて互いに係止し(図6(a))、加熱加圧ヘッド19で加熱加圧して、両者を接続する(図6(b))。この第3実施の形態では、終端部30と始端部32とを鉤状に連結するので強固に連結できるとともに、互いに接着剤11を重ねて接続するので、更に強固な接続を得ることができる。上記と同様に重ねた部分の接着剤が流動し端面でも接着されるので、さらに強固な接続を得ることができる
【0020】
図7に示す第4実施の形態では、第1実施の形態において、加熱加圧前又は、加熱加圧と同時に重な合わせ部分34に貫通孔47をあける。貫通孔47をあけることで、貫通孔47の周囲から加熱加圧時に接着剤11が染み出し、これらが接着するので、接着力を高めることができ、重ね合わせ部34では強固な接続を得ることができる。
【0021】
本発明は、上述した実施の形態に限らず、本発明の要旨を逸脱しない範囲で種々変形可能である。
例えば、上述した第2実施の形態において、凹凸45は山型にすることなく、丸みを帯びた丸型であってもよい。
第4実施の形態において、貫通孔47の数は、特に制限はなく幾つあってもよい。また、貫通孔47の径も制限されない。また、第2、第3実施の形態において、更に重ね合わせ部分34に貫通孔47を形成してもよい。
【0022】
【発明の効果】
請求項1に記載の発明によれば、接着剤テープの接着剤を利用して終了した接着剤テープの終端部と、新たに装着する接着剤テープの始端部とを接着して、接着剤リールの交換を行うので、接着装置への新たな接着剤リールの装着が簡単にできる。また、新たな接着剤リールの交換毎に基材の巻取りリールの交換や新規接着剤の始端を巻取りリールに取り付ける必要がないので、新しい接着剤リールの交換時間が少なくて済み、製造効率が高まる。
請求項2に記載の発明によれば、請求項1に記載の発明と同様な効果を奏するとともに、一方の接着剤テープの終端部と他方の接着剤テープの始端部とを互いに鉤状にして係止するとともに、両者は接着剤面を互いに接続するので、接続強度が高い。
請求項3に記載の発明によれば、請求項1又は請求項2記載の発明と同様な効果を奏するとともに、一方の接着剤テープの終端部はエンドマーク部分で行うことができるので、接続作業をする部分が解りやすく且つ接着剤テープの無駄を防止できる。
請求項4に記載の発明によれば、請求項1〜3のいずれか一項に記載の発明と同様な効果を奏するとともに、接続部分に凹凸を形成することより、接続面積を広くできるとともに、接続部分における接着剤テープの引張り方向(長手方向)の強度を高めることができる。
請求項5に記載の発明によれば、請求項1〜3のいずれか一項に記載の発明と同様な効果を奏するとともに、接続部分に貫通孔を形成することにより、貫通孔の内周に接着剤が染み出して、接着剤による接着面積が増えるので、更に接続強度を高めることができる。

[Problems to be solved by the invention]
However, with the recent increase in panel screen size in PDPs and the like, the adhesion area of circuit boards has increased, and the amount of adhesive used at one time has increased. Moreover, since the use of adhesives has expanded, the amount of adhesives used has increased. For this reason, there is a problem in the electronic device manufacturing factory that the frequency of replacement of the adhesive reel is increased, and it takes time to replace the adhesive reel, so that the production efficiency of the electronic device cannot be improved.
For such problem, by increasing the number of turns of adhesive tape wound into a reel, increasing the amount of adhesive per reel, it is conceivable to reduce the frequency of replacing the reels, the tape of the adhesive tape Since the width is as narrow as 1 to 3 mm, if the number of windings is increased, collapse may occur.
