Description
金めっきは、エレクトロニクス産業において、典型的には電気コネクタ及びプリント回路板中で耐食性の電気伝導層を銅ベース層上に設けるためにしばしば使用される。バリヤー金属を用いないと、前記銅原子は、前記金層に拡散する傾向があり、それによりその表面のさびつき及び酸化物及び/又は硫化物層の形成を引き起こす。ニッケル、ニッケルリン合金、ニッケルホウ素合金、ニッケルパラジウム合金又はパラジウムのような1つ又はそれ以上の適したバリヤー金属又は金属合金の中間層は、そのような望ましくない拡散を防止するために前記金めっきの前に前記銅基板上へ好ましくは堆積される。例えば、ニッケル及びニッケルリン合金の中間層は付加的に、前記金層のための機械的支持(backing)を提供し、かつその耐摩耗性を改善する。前記中間層はまた、前記金層中に存在する細孔により引き起こされる腐食を減少させる。
本発明は、水性後処理組成物及び金属表面及び/又は金属合金表面の防食のための前記組成物を用いる浸漬法及び/又は電解法に関する。前記水性後処理組成物は、少なくとも1つのポリシロキサンベタイン化合物及び少なくとも1つの含リン化合物を含んでなる。
本発明は、金属表面又は金属合金表面、好ましくは加工物の金表面又は金合金表面の耐食性を高める方法に関する。説明の目的のために、そのような加工物の1つは、電子リードフレーム、受動部品、ウェーハ上のバンプ又は電気コネクタのような電子部品である。
式I:
1.前記基板上へのニッケル層の堆積
2.場合により前記ニッケル層上へのニッケル−リン層の堆積
3.前記ニッケル又はニッケル−リン層上への金又は金ベースの合金層の堆積。
全ての例に記載された金属コーティングは、本明細書の10頁に提供されたプロセスシーケンスに従って第1表に示されたように調製した。
