style="text-indent:25px">鍍銀工藝蕞早出現(xiàn)在十九世紀(jì)元年，蕞早的鍍銀**是英國(guó)伯明翰兩兄弟與1838年提出申請(qǐng)的，當(dāng)時(shí)電鍍銀使用的電鍍液是呈堿性的**物鍍液。到現(xiàn)在為止，鍍銀液的配方和早期的配方基本上沒(méi)有太大的區(qū)別，***的區(qū)別可能在于提高了銀配位離子濃度從而達(dá)到快速鍍銀的目的罷了。近些年來(lái)，快速發(fā)展的額電子元器件都選擇性鍍銀，比如引線框架的選擇性鍍銀，并采用噴射鍍的方法進(jìn)行鍍銀。電鍍銀所用的電流密度高達(dá)300~3000A/dm，鍍液中**銀鉀[KAg(CN)2]的濃度高達(dá)40~75g/L，陽(yáng)極采用白金或鍍鉑的鈦陽(yáng)極。</p><div
