Abstract
【解決手段】流路形成基板10と、該流路形成基板10上に設けられた一つ以上の実装部90を有するアクチュエーター装置300と、前記実装部90に電気的に接続されて、駆動信号をアクチュエーター装置300に供給する可撓性を有する配線基板200と、を具備し、前記アクチュエーター装置の前記実装部と前記配線基板との接合が、p−アミノフェノール型エポキシ樹脂、ビスフェノールA型エポキシ樹脂及びビスフェノールF型エポキシ樹脂を含有するエポキシ接着剤を介して行われている。
【選択図】 図2
Description
かかる態様では、流路形成基板と配線基板との接合を、所定組成のエポキシ樹脂を用いて行っているので、噴射される液体との接触によっても膨潤が抑えられ、長期に亘って導通不良が生じることがない。
かかる態様では、噴射される液体との接触によっても接着剤の膨潤が抑えられ、長期に亘って導通不良が生じることがない液体噴射装置を実現できる。
図1は、本発明の第1の実施の形態に係る液体噴射ヘッドの一例であるインクジェット式記録ヘッドの概略構成を示す分解斜視図であり、図2は、図1の平面図及びそのA−A′線断面図である。
p−アミノフェノール型エポキシ樹脂を5〜10質量%と、ビスフェノールA型エポキシ樹脂を5〜10質量%と、ビスフェノールF型エポキシ樹脂を45〜50質量%と、脂肪族ポリアミンを主成分とする硬化剤を30〜40質量%とを含有するエポキシ樹脂接着剤を用いた。
p−アミノフェノール型エポキシ樹脂を6〜10質量%と、ビスフェノールA型エポキシ樹脂を2〜5質量%と、ビスフェノールF型エポキシ樹脂を30〜40質量%と、脂肪族ポリアミンを主成分とする硬化剤を20〜30質量%とを含有するエポキシ樹脂接着剤を用いた。
p−アミノフェノール型エポキシ樹脂を20〜25質量%と、ビスフェノールA型エポキシ樹脂を10〜15質量%と、ビスフェノールF型エポキシ樹脂を40〜50質量%と、脂肪族ポリアミンを主成分とする硬化剤を10〜20質量%とを含有するエポキシ樹脂接着剤を用いた。
ビスフェノールA型エポキシ樹脂を40質量%と、硬化剤を40〜50質量%とを含有するエポキシ樹脂接着剤を用いた。
実施例1〜3及び比較例のエポキシ樹脂接着剤の硬化物をサンプルとし、溶剤系のインクに144時間(6日間)浸漬し、浸漬後の硬化物の重量増加率を測定した。
実施例1のエポキシ樹脂接着剤を含む異方性導電性材料を用いてCOF基板410を流路形成基板10に接合した記録ヘッドと、比較例のエポキシ樹脂接着剤を含有する異方性導電性材料を用いた記録ヘッドとを、60℃飽和インク雰囲気中に放置し、長期使用状態を模した加速試験を行った。
上記実施の形態は、流路形成基板10に圧力発生室12が並設された列を2列設けたものであるが、この場合の列数には特別な制限はない。一列でも良いし、3列以上であっても構わない。複数列の場合には少なくとも2列一組を相対抗させて設ければ良い。
