Description
本発明のバリヤ層の利点は次の実施例から更に明らかになるであろう。
Cu−20%Ni
Fe
Ni
Cu
の群から選ばれた特定のバリヤ層の30マイクロインチ(0.75μ)によって被覆された銅合金C194クーポン、及びバリヤ層無しの銅合金C194及びC710(6.5%IACSの公称電気伝導率もつ、重量で80%の銅と20%のニッケルの公称組成) の対照クーポンを、電着によって40マイクロインチ(1μ)の艶消錫で被覆した。
銅合金C194クーポンを1μ(40マイクロインチ)の銅−30重量%ニッケル合金のバリヤ層で被覆し、それから1.25μ(50マイクロインチ)の艶消錫で被覆した。艶消錫は後で再フローされた。バリヤ層及び艶消錫はどちらも電解的に付着させられた。バリヤ層の銅とニッケルは同時付着された。
対照は後で再フローされた艶消錫によって電解的に被覆された銅合金C194クーポンであった。対照はバリヤ層を欠いていた。
図8は銅合金C194基質/銅−30%ニッケル/錫のプレートシステムにおいて基質/バリヤ層が熱的又は機械的加工を受けない場合に発現する銅/錫の金属間化合物を例証する2000Xの倍率の顕微鏡写真である。金属間化合物は残留錫を選択的に化学的に除去することによって裸出された。金属間化合物は急速に成長するスフェロイド(spheroid)からなる。
