蝕刻工藝是一項我們都不陌生的工藝，在很多的行業中，都是有涉及到的。那么蝕刻工藝在施工的時候有什么需要注意的問題呢？下面小編給大家介紹一下蝕(shi)刻加工的工藝需要(yao)注意的問題有哪些。

一(yi)、我們(men)需(xu)要(yao)做的(de)(de)就(jiu)是,提升板(ban)(ban)子與板(ban)(ban)子之間蝕(shi)刻(ke)(ke)效率的(de)(de)一(yi)致(zhi)性若是我們(men)在(zai)(zai)進(jin)行(xing)連續的(de)(de)板(ban)(ban)子蝕(shi)刻(ke)(ke)工藝的(de)(de)時候,首先要(yao)做的(de)(de)就(jiu)是讓(rang)蝕(shi)刻(ke)(ke)速(su)率一(yi)致(zhi),這(zhe)樣(yang)才可(ke)以獲得均勻蝕(shi)刻(ke)(ke)的(de)(de)板(ban)(ban)子。而(er)我們(men)想要(yao)達到這(zhe)一(yi)要(yao)求(qiu)的(de)(de)話呢,就(jiu)必(bi)須保(bao)證蝕(shi)刻(ke)(ke)液在(zai)(zai)蝕(shi)刻(ke)(ke)工藝的(de)(de)全過程始終(zhong)保(bao)持(chi)在(zai)(zai)佳的(de)(de)蝕(shi)刻(ke)(ke)狀態(tai)。這(zhe)就(jiu)要(yao)求(qiu)我們(men)選擇容易再生(sheng)和補償,蝕(shi)刻(ke)(ke)速(su)率容易控制(zhi)的(de)(de)蝕(shi)刻(ke)(ke)液。選用(yong)能提供恒定(ding)的(de)(de)操作條件和對各(ge)種(zhong)溶(rong)(rong)液參(can)數能自(zi)動(dong)控制(zhi)的(de)(de)工藝和設備。通過控制(zhi)溶(rong)(rong)銅(tong)量, PH值,溶(rong)(rong)液的(de)(de)濃度(du),溫度(du),溶(rong)(rong)液流量的(de)(de)均勻性等來實(shi)現。

二、還需要提(ti)高整(zheng)個(ge)(ge)(ge)板(ban)(ban)(ban)(ban)(ban)(ban)子(zi) 表面(mian)(mian)蝕(shi)刻(ke)(ke)(ke)(ke)(ke)工(gong)藝速(su)率(lv)(lv)的(de)(de)均(jun)(jun)勻(yun)性(xing)(xing)板(ban)(ban)(ban)(ban)(ban)(ban)子(zi)上(shang)(shang)下(xia)兩面(mian)(mian)以及板(ban)(ban)(ban)(ban)(ban)(ban)面(mian)(mian)上(shang)(shang)各(ge)個(ge)(ge)(ge)部位(wei)的(de)(de)蝕(shi)刻(ke)(ke)(ke)(ke)(ke)均(jun)(jun)勻(yun)性(xing)(xing)是(shi)(shi)由(you)板(ban)(ban)(ban)(ban)(ban)(ban)子(zi)表面(mian)(mian)受到(dao)蝕(shi)刻(ke)(ke)(ke)(ke)(ke)劑流量(liang)的(de)(de)均(jun)(jun)勻(yun)性(xing)(xing)決定的(de)(de)。蝕(shi)刻(ke)(ke)(ke)(ke)(ke)過(guo)程中(zhong)(zhong)，上(shang)(shang)下(xia)板(ban)(ban)(ban)(ban)(ban)(ban)面(mian)(mian)的(de)(de)蝕(shi)刻(ke)(ke)(ke)(ke)(ke)速(su)率(lv)(lv)往往不(bu)一(yi)(yi)致。-般(ban)來說，下(xia)板(ban)(ban)(ban)(ban)(ban)(ban)面(mian)(mian)的(de)(de)蝕(shi)刻(ke)(ke)(ke)(ke)(ke)速(su)率(lv)(lv)高于(yu)上(shang)(shang)板(ban)(ban)(ban)(ban)(ban)(ban)面(mian)(mian)。因為上(shang)(shang)板(ban)(ban)(ban)(ban)(ban)(ban)面(mian)(mian)有溶液(ye)的(de)(de)堆積,減弱了蝕(shi)刻(ke)(ke)(ke)(ke)(ke)反應(ying)的(de)(de)進(jin)行。可(ke)以通(tong)過(guo)調整(zheng)上(shang)(shang)下(xia)噴(pen)嘴的(de)(de)噴(pen)啉壓力來解(jie)決上(shang)(shang)下(xia)板(ban)(ban)(ban)(ban)(ban)(ban)面(mian)(mian)蝕(shi)刻(ke)(ke)(ke)(ke)(ke)不(bu)均(jun)(jun)的(de)(de)現象。蝕(shi)刻(ke)(ke)(ke)(ke)(ke)印制板(ban)(ban)(ban)(ban)(ban)(ban)的(de)(de)一(yi)(yi)一(yi)(yi)個(ge)(ge)(ge)普遍問題是(shi)(shi)在(zai)相同時間里使(shi)全部板(ban)(ban)(ban)(ban)(ban)(ban)面(mian)(mian)都蝕(shi)刻(ke)(ke)(ke)(ke)(ke)工(gong)藝干凈是(shi)(shi)很難做到(dao)的(de)(de),板(ban)(ban)(ban)(ban)(ban)(ban)子(zi)邊(bian)緣(yuan)比板(ban)(ban)(ban)(ban)(ban)(ban)子(zi)中(zhong)(zhong)心部位(wei)蝕(shi)刻(ke)(ke)(ke)(ke)(ke)的(de)(de)快(kuai)。采用噴(pen)淋(lin)系(xi)統并使(shi)噴(pen)嘴擺動是(shi)(shi)一(yi)(yi)個(ge)(ge)(ge)有效的(de)(de)措施(shi)。 更進(jin)一(yi)(yi)步的(de)(de)改(gai)善(shan) 可(ke)以通(tong)過(guo)使(shi)板(ban)(ban)(ban)(ban)(ban)(ban)中(zhong)(zhong)心和板(ban)(ban)(ban)(ban)(ban)(ban)邊(bian)緣(yuan)處的(de)(de)噴(pen)淋(lin)壓力不(bu)同,板(ban)(ban)(ban)(ban)(ban)(ban)前沿和板(ban)(ban)(ban)(ban)(ban)(ban)后端間歇蝕(shi)刻(ke)(ke)(ke)(ke)(ke)的(de)(de)辦法,達到(dao)整(zheng)個(ge)(ge)(ge)板(ban)(ban)(ban)(ban)(ban)(ban)面(mian)(mian)的(de)(de)蝕(shi)刻(ke)(ke)(ke)(ke)(ke)均(jun)(jun)勻(yun)性(xing)(xing)。
