Description
アゾール系化合物としては、イミダゾール、オキサゾール、チアゾール、セレナゾール、ピラゾール、イソオキサゾール、イソチアゾール、トリアゾール、オキサジアゾール、チアジアゾール、テトラゾール、オキサトリアゾール、チアトリアゾール、ベンダゾール、インダゾール、ベンズイミダゾール、ベンゾトリアゾールなどが挙げられる。これらに制限されるものではないが、イミダゾールが特に好ましい。
また、本発明の無電解めっき前処理剤層の膜厚は1〜200nmが好ましい。
市販のポリイミドフィルムカプトン(200H、東レデュポン製)の表面に、イミダゾールシラン(イミダゾールと3−グリシドキシプロピルトリメトキシシランの等モル反応生成物)1g/Lと、Pd石鹸(ナフテン酸Pd、日鉱マテリアルズ製)0.5g/L(Pd換算100mg/L)と、エポキシ樹脂(エピコートEP828、ジャパンエポキシレジン製)1g/Lを含んだ有機溶媒(ブタノール)系無電解めっき前処理剤を塗布した。150℃で溶媒除去し、膜厚70nmの前処理剤層を形成した後、無電解銅めっき(めっき液:NKM554、日鉱メタルプレーティング製)により膜厚0.5μmの銅めっき層を形成し、次に、電流密度2A/dm2で電気銅めっき(めっき液:硫酸銅系、日鉱メタルプレーティング製)を行ない、膜厚35μmの銅めっき層を形成した。その常態でのピール強度、その後空気中150℃、168時間エージングした後のピール強度をそれぞれ測定した。ピール強度はJIS C−6481に基づく90度引き剥がし試験による。以下の実施例、比較例においても同様である。結果は表1の通り、エージング後での強度も0.7kgf/cmと高い数値を示した。
市販のポリイミドフィルムカプトン(200H、東レデュポン製)の表面に、イミダゾールシラン(イミダゾールと3−グリシドキシプロピルトリメトキシシランの等モル反応生成物)1g/LとPd石鹸(ナフテン酸Pd、日鉱マテリアルズ製)0.5g/L(Pd換算100mg/L)と、フェノール樹脂(XLC−4L、三井化学製)2g/Lを含んだ有機溶媒(ブタノール)系無電解めっき前処理剤を塗布した。150℃で溶媒除去し、膜厚70nmの前処理剤層を形成した後、無電解銅めっき(めっき液:NKM554、日鉱メタルプレーティング製)により膜厚0.5μmの銅めっき層を形成し、次に、電気銅めっき(めっき液:硫酸銅系、日鉱メタルプレーティング製)を行ない、膜厚35μmの銅めっき層を形成した。その常態でのピール強度、その後空気中150℃、168時間エージングした後のピール強度をそれぞれ測定した。
実施例1のイミダゾールシランの変わりにアミノシラン(γ−アミノプロピルトリエトキシシラン、信越化学製)を用いた以外は実施例1と同様に処理・試験を行なった。結果は表1の通り、エージング後での強度も0.4kgf/cmと高い数値を示した。
エポキシ樹脂を含まない以外は実施例1と同様に処理・試験を行なった。結果は表1の通り、初期ピール強度は0.9kgf/cmと高かったが、エージング後のピール強度は0.1kgf/cmと低いものとなった。
スパッタリング法により銅シード層を0.5μm形成した後、実施例1と同様に電気銅めっきで35μmの銅めっき層を形成し、実施例1と同様に試験を行なった。結果は表1の通り、初期ピール強度は0.9kgf/cmと高かったが、エージング後は低いものとなった。
