実施例1~7の樹脂組成物で得られた多層銅張積層板について、耐薬品性を評価した。尚、評価サンプルは、前記で得られた多層銅張積層板の外層銅箔をエッチング除去し、所定の大きさに切断して用いた。
評価サンプルを、80℃の膨潤液(アトテックジャパン社製・「スウェリングディップ セキュリガント P500」)に5分間浸漬し、さらに80℃の過マンガン酸カリウム水溶液(アトテックジャパン社製・「コンセントレート コンパクト CP」)にて10分浸漬して酸化処理を行った後、中和した。乾燥後にSEMにて樹脂表面を観察した。
エッチング除去した評価サンプルの表面は、サンプル作成の際に用いた厚さ12μmの銅箔(三井金属鉱業社製)の粗面が転写された状態になる。過マンガン酸カリウム水溶液で過剰に酸化処理すると、樹脂が酸化除去されフィラーが露出する。SEMによる樹脂表面の観察では、転写された粗度形状、樹脂のひび割れ、及びフィラー露出の有無を確認し、酸化処理前の銅箔粗面の転写形状が維持されている状態を問題なし(OK)と評価した。また、酸化処理前の銅箔粗面の転写形状が維持されておらず、フィラーが露出した状態を問題あり(NG)と評価した。
参考のため、多層銅張積層板の外層銅箔をエッチング除去して得られた評価サンプル(すなわち薬液処理なしのもの)のSEM写真を図1に示す。また、評価サンプルを薬液処理した後にOKと判定された例の写真を図2に示す。また、評価サンプルを薬液処理した後にNGと判定された例の写真を図3に示す。
また、表3に示した参考実験1および2の結果から、本発明の樹脂組成物は、フェノール樹脂を含有しないことが、優れた耐湿信頼性および耐薬品性が得られる点で好ましいことが分かった。従来、エポキシ樹脂、シアネート樹脂およびフェノール樹脂を含有する樹脂組成物がプリント配線板の絶縁層またはプリプレグに用いられているが、PCT環境での耐湿信頼性および耐薬品性が充分でないことが多い。これに対し、実施例で用いた樹脂組成物は、フェノール樹脂を含有しないため、耐湿信頼性および耐薬品性が優れていた。
