1. 厚沉積堿性(xing)銅電刷(shua)鍍液的(de)性(xing)質

  ①. 厚(hou)沉積堿(jian)性銅電刷(shua)鍍液(ye)呈堿(jian)性，pH=8.5~9.5,呈藍紫色。

  ②. 沉積速(su)率快，一次(ci)鍍厚能(neng)力大。

  ③. 可以直(zhi)接在不(bu)銹鋼(gang)工件上沉積銅(tong)(tong)，不(bu)會產生置(zhi)換反應，乙(yi)二胺與銅(tong)(tong)形成(cheng)的配離子(zi)最穩定，金屬鐵原子(zi)不(bu)能從胺合銅(tong)(tong)的配離子(zi)中置(zhi)換銅(tong)(tong)。

  ④. 鍍液價格(ge)較貴(gui)，且(qie)含乙二胺，有毒，加強勞動保護，不可與(yu)皮膚接觸。

2. 厚沉積堿(jian)性銅電刷鍍銅液的用途

  厚沉積堿性銅(tong)電刷鍍銅(tong)主要(yao)(yao)用來沉積過渡層和需要(yao)(yao)用銅(tong)來沉積厚尺(chi)寸的場合。

3. 厚沉積(ji)堿性銅(tong)電刷鍍(du)液(ye)成分(fen)

 甲基磺酸銅［Cu(CH₃SO₃)₂]  322g/L   、氯化鈉（NaCl)  1g/L

 乙二胺［（NH₂CH₂)₂]  178mL/L  、pH8.5~9.5

4. 厚沉積堿(jian)性銅電(dian)刷(shua)鍍液的配制

  在1000mL燒(shao)杯(bei)(bei)中加(jia)入(ru)甲(jia)基磺酸銅322g,加(jia)入(ru)蒸餾水400mL,攪(jiao)拌(ban)(ban)溶(rong)解后，在攪(jiao)拌(ban)(ban)下緩慢滴加(jia)乙二(er)胺(an)178mL,再加(jia)入(ru)氯(lv)化鈉1g,攪(jiao)拌(ban)(ban)溶(rong)解，用乙二(er)胺(an)或甲(jia)基碳酸調節pH約9,最后倒人(ren)1000mL量筒或量杯(bei)(bei)中，加(jia)蒸餾水至(zhi)刻度(du)。

  如(ru)(ru)(ru)無甲(jia)基磺(huang)(huang)(huang)酸(suan)銅(tong)(tong)(tong)，可(ke)用堿(jian)式碳(tan)酸(suan)銅(tong)(tong)(tong)［Cu(OH)2·CuCO3]和甲(jia)基磺(huang)(huang)(huang)酸(suan)（CH3SO3H)配(pei)制成甲(jia)基磺(huang)(huang)(huang)酸(suan)銅(tong)(tong)(tong)。方(fang)法如(ru)(ru)(ru)下(xia)：稱取堿(jian)式碳(tan)酸(suan)銅(tong)(tong)(tong)161g放入1000mL燒杯中(zhong)(zhong)，加(jia)(jia)(jia)蒸(zheng)餾水(shui)400mL,在攪拌(ban)下(xia)滴(di)加(jia)(jia)(jia)甲(jia)基磺(huang)(huang)(huang)酸(suan)至碳(tan)酸(suan)銅(tong)(tong)(tong)中(zhong)(zhong)使(shi)恰好溶(rong)(rong)解(jie)為止(zhi)，即化合(he)得甲(jia)基磺(huang)(huang)(huang)酸(suan)銅(tong)(tong)(tong)。甲(jia)基磺(huang)(huang)(huang)酸(suan)不可(ke)過量(liang)(liang)，否則(ze)溶(rong)(rong)液pH將低(di)于8.5。如(ru)(ru)(ru)有少量(liang)(liang)甲(jia)基磺(huang)(huang)(huang)酸(suan)銅(tong)(tong)(tong)未溶(rong)(rong)解(jie)，可(ke)加(jia)(jia)(jia)熱攪拌(ban)溶(rong)(rong)解(jie)。然后冷卻(que)至室溫，在攪拌(ban)下(xia)緩慢滴(di)加(jia)(jia)(jia)乙二胺(an)178mL,用乙二胺(an)和甲(jia)基磺(huang)(huang)(huang)酸(suan)調節pH至9左(zuo)右(you)，加(jia)(jia)(jia)氯化鈉(na)1g,攪拌(ban)溶(rong)(rong)解(jie)后倒入1000mL量(liang)(liang)筒或量(liang)(liang)瓶中(zhong)(zhong)，加(jia)(jia)(jia)蒸(zheng)餾水(shui)至刻度。
