鍍銅工藝中需要對(duì)工藝進(jìn)行控制，主要需要控制包括鍍液控制、溫度控制，鍍銅完成后需要對(duì)鍍液進(jìn)行清潔維護(hù)工作。鍍液的成分控制主要是對(duì)***銅、***和添加劑的控制。***銅作為主要的鍍劑，濃度要控制在合理的范圍；***則在鍍銅工藝中起到活化鋼絲表面和穩(wěn)定鍍液李銅鹽（銅元素）發(fā)生水解；添加劑的劑量起到緩沖銅層成績(jī)速度、細(xì)化結(jié)晶的作用。鍍銅加工中需要加熱，升溫加熱能促進(jìn)反應(yīng)速度，但是溫度也是需要控制在一定的范圍，如果溫度太高會(huì)降低鍍液的穩(wěn)定性，且反應(yīng)速度過(guò)快，不易控制，鍍出來(lái)的銅層效果不太好。 </p><p> 硫|酸鹽鍍銅電流密度范圍較寬，而且與鍍液溫度、濃度、攪拌密切相關(guān)。光亮電流密度范圍隨著鍍液中硫|酸銅含量的降低、硫|酸含量的增加而縮小，隨著溫度的增加、攪拌的加強(qiáng)，光亮電流密度范圍增大。陽(yáng)極電流密度對(duì)于鍍液的穩(wěn)定性和鍍層質(zhì)量也有明顯影響。當(dāng)陰極電流密度過(guò)高時(shí)，鍍層光亮度差，添加劑的消耗也快，且易鈍化，因此當(dāng)使用大電流電鍍時(shí)陽(yáng)極面積必須充足。光亮鍍銅工藝都要使用陰極移動(dòng)或空氣攪拌，以消除濃差極化，以便采用較高的陰極電流密度，加快速度。裝飾防護(hù)性酸性光亮銅更著重于亮度，印制板的酸性光亮銅更著重于鍍層的脆性和分散能力。</p><div
