Description
本出願は、日本国において2009年9月30日に出願された日本特許出願番号特願2009-225771を基礎として優先権を主張するものであり、この出願を参照することにより、本出願に援用される。
図1は、本発明の一実施の形態に係る異方性導電フィルムを示す断面図である。この異方性導電フィルム10は、200kPa以上のタック力を有する第1の樹脂層11と、導電性粒子を含有する第2の樹脂層12とが積層されている。この異方性導電フィルム10を用いて電子部品をガラス基板に実装させる場合、電子部品側が第1の樹脂層11、ガラス基板側が第2の樹脂層12となるように固着される。特に、本実施の形態に係る異方性導電フィルム10は、表面実装機によって第1の樹脂層11上に電子部品が複数仮搭載され、熱圧着により電子部品と他の電子部品とを同時実装するのに用いられる。表面実装機としては、例えば1.0~0.1秒/チップ程度に高速仮搭載可能なものを用いることができる。また、表面実装機を用いて仮搭載する電子部品としては、表面実装機に適用可能なSMD(Surface Mount Device)であれば、特に制限されないが、例えば液晶表示装置を製造する際のSMDとしてはコンデンサを挙げることができる。
の観点から、第2の樹脂層12の最低溶融粘度は、第1の樹脂層11の最低溶融粘度よりも高いことが好ましい。具体的には、第2の樹脂層12を構成する樹脂の最低溶融粘度は、100~100000Pa・sであることが好ましく、第1の樹脂層11を構成する樹脂の最低溶融粘度は、10~10000Pa・sであることが好ましい。最低溶融粘度については、サンプルを所定量回転式粘度計に装填し、所定の昇温速度で上昇させながら測定することができる。
12上に透明なカバーフィルムを有する構成としてもよい。また、異方性導電フィルム10は、リール形状に限らず、短冊形状であってもよい。
次に、上述した異方性導電フィルムの製造方法について説明する。本実施の形態における異方性導電フィルムの製造方法は、200kPa以上のタック力を有する第1の樹脂膜を、導電性粒子を含有する第2の樹脂膜上に形成する。ここで、第1の樹脂膜と第2の樹脂膜とを貼り付けてもよいし、一方の樹脂膜を形成後、他方の樹脂を塗布乾燥(重ね塗り)させてもよい。なお、第1の樹脂膜及び第2の樹脂膜は、それぞれ第1の樹脂層11及び第2の樹脂層12を構成する。
次に、異方性導電フィルムを用いた電子部品の実装方法について説明する。本実施の形態に係る異方性導電フィルムは、タック力が高いため小型SMDを高速仮搭載しても位置ずれが生じにくい。また、2層構造であるため、粒子捕捉性が良く、ファインピッチのICを実装することができる。すなわち、本実施の形態に係る異方性導電フィルムによれば、大きさ、種類などの異なる電子部品を一括実装することができる。
