PCBA打樣廠有一些板材需要覆銅處理。根據(jù)覆銅板的機械剛度,有剛性覆銅板和柔性覆銅板之分。鍍銅可以有效降低SMT芯片加工產(chǎn)品的接地阻抗,提高抗干擾能力,降低壓降,提高功率效率,減少回路面積。鍍銅是貼片印刷電路板非常有用的加工方法,在鍍銅加工中需要注意的點很多。所謂鍍銅,就是把PCB上的閑置空間作為基準面,然后用實心銅填充。這些銅區(qū)域也被稱為銅填充。鍍銅的意義在于降低地線阻抗,提高抗干擾能力;降低壓降,提高功率效率;此外,連接地線以減少回路面積。銅包線有幾個問題需要處理:一是異地單點連接,用0歐姆電阻或磁珠

PCBA打樣小批量的質(zhì)量檢測有哪些,為了完成PCBA加工一次合格率和高牢靠性的質(zhì)量目的,需求對印刷電路板設(shè)計計劃、元器件、材料、工藝、設(shè)備、規(guī)章制度等停止控制。其中,基于過程控制在PCBA打樣制造業(yè)中尤為重要。在PCBA打樣制造過程的每一步,都要按照合理的檢測辦法,防止各種缺陷和隱患,才干進入下一道工序。 PCBA打樣加工和焊接檢測是對焊接產(chǎn)品的全面檢測。普通需求檢測的點有:檢測點焊外表能否光亮,有無孔洞、孔洞等;點焊能否呈月牙形,有無多錫少錫,有無立碑、橋梁、零件挪動、缺件、錫珠等缺陷。各

我經(jīng)常聽到人們談論SMT指針。對于業(yè)內(nèi)廣大人士來說,這種設(shè)備并不陌生。其實SMT指針也叫部分計數(shù)器。那么,你對這個設(shè)備的功能了解多少?   據(jù)相關(guān)業(yè)內(nèi)人士介紹,SMT芯片加工中使用的SMT指針是基于光電傳感原理,通過零件載體利用導孔與零件的對應關(guān)系,可以精確測量SMD零件的數(shù)量,從而達到方便快捷計數(shù)的目的……

車間是PCBA工廠的大動脈,大局部的消費與加工都要在車間內(nèi)部停止。關(guān)于一家PCBA工廠而言,車間的環(huán)境及人員素質(zhì)是彰顯其公司文化修養(yǎng)與優(yōu)秀水平的關(guān)鍵。那么今天,我們就走進車間,理解一下PCBA打樣加工對車間環(huán)境及人員的請求吧。 PCBA打樣加工的PCBA消費設(shè)備和SMT貼片加工工藝對車間的電源、通風才能、溫度、濕……
