(D)一般式(1):
を含有することを特徴とする。
表1〜表3に示す配合で、樹脂組成物を作製した。作製した樹脂組成物は、すべて液状であった。また、〔(B)成分の酸無水、フェノールまたはアミン当量〕/〔(A)成分のエポキシ当量〕は、実施例1〜27、比較例1、2のすべてで0.82にした。
作製した直後の樹脂組成物の粘度(単位:mPa・s)を、東機産業社製E型粘度計(型番:TVE−22H)を用い、毎分50回転の条件で測定した。表1〜表3に、測定結果を示す。
樹脂組成物のゲルタイムは、150℃に熱した熱板上に、樹脂組成物:5±1mgを供給し、攪拌棒によって円を描くようにして攪拌しながら攪拌棒を持ち上げて引き離した場合に、糸引きが5mm以下となるまでの時間を測定することによって得た。ゲルタイムの適正範囲は、10〜100秒である。表1〜表3に、測定結果を示す。
樹脂組成物の揺変指数を、東機産業社製E型粘度計(型番:TVE−22H)を用いて測定した。揺変指数は、毎分5回転の条件で求められた測定値を、毎分50回転の条件で求められた測定値で除した比率、すなわち、(毎分5回転での粘度)/(毎分50回転での粘度)がから求めた。揺変指数の適正範囲は、0.8〜3.0である。表1〜表3に、測定結果を示す。
各樹脂組成物を、硬化後の寸法が5mmφ×3mmになるように、150℃で30分間硬化させた。これを、ブルカーASX社製熱機械分析装置(型番:TMA4000SAシリーズ)を用いてTMA法圧縮モードで測定し、熱膨張係数を求めた。熱膨張係数の適正範囲は、3〜20ppm/℃である。
樹脂組成物のマイグレーション特性を評価するために、THB試験を行った。ここで、銅製ワイヤーを使用するパターンでは、ワイヤーピッチが約100μmであったので、加速試験として、ラインピッチが10μmの櫛歯電極を使用した。ポリイミド(東レ・デュポン製カプトン)基板上に形成された櫛歯電極(ライン/スペース=10μm/10μm、SnメッキしたCu電極)上へ、各樹脂組成物を塗布し、硬化(150℃×30分)させ、評価サンプルを作製した(n=3)。評価サンプルを、温度85℃、湿度85%の恒温層へ入れ、櫛歯電極へ60Vの電圧を印加させながら、抵抗値を測定し、109Ω以下になるまでの時間を評価した。なお、THB試験は、500時間までの評価を行った。THB試験は、80時間以上であると好ましく、500時間以上であると、より好ましい。表1〜表3に、測定結果を示す。
温度サイクル試験(―55℃/125℃(30分/30分))を行い、温度サイクル試験後の抵抗値の変化を評価した。温度サイクル試験では、抵抗値の変化がない状態が100回以上であると好ましく、500回以上であると、より好ましい。
