在PCBA加工中(zhong)，將嚴(yan)格要求工作(zuo)人員(yuan)按照儀(yi)表(biao)或SMT組件(jian)(jian)的物料清單，PCB印刷和外包加工要求進行操作(zuo)，但電(dian)(dian)(dian)子組件(jian)(jian)通常會(hui)或多或少地(di)被靜(jing)(jing)電(dian)(dian)(dian)破壞(huai)，會(hui)釋(shi)放出靜(jing)(jing)電(dian)(dian)(dian)在釋(shi)放電(dian)(dian)(dian)磁脈沖時(shi)(shi)，在計(ji)算錯(cuo)誤時(shi)(shi)有時(shi)(shi)還會(hui)損壞(huai)設(she)備(bei)和電(dian)(dian)(dian)路。1.所有接(jie)觸組件(jian)(jian)和產品的人員(yuan)均應穿著防(fang)靜(jing)(jing)電(dian)(dian)(dian)服(fu)，防(fang)靜(jing)(jing)電(dian)(dian)(dian)手鐲(zhuo)和防(fang)靜(jing)(jing)電(dian)(dian)(dian)鞋。2.防(fang)靜(jing)(jing)電(dian)(dian)(dian)系統必須具有可(ke)靠的接(jie)地(di)裝(zhuang)置。防(fang)靜(jing)(jing)電(dian)(dian)(dian)接(jie)地(di)線(xian)不得連接(jie)至(zhi)電(dian)(dian)(dian)源的零(ling)線(xian)，且不得與防(fang)雷(lei)接(jie)地(di)線(xian)共用。3.所有組件(jian)(jian)均視為(wei)靜(jing)(jing)電(dian)(dian)(dian)敏(min)感(gan)設(she)備(bei)。

在電子加(jia)工(gong)(gong)(gong)生(sheng)產(chan)行業中企業遇到(dao)加(jia)急訂單是(shi)常有的(de)(de)事，沈陽(yang)貼片(pian)加(jia)工(gong)(gong)(gong)，而進(jin)行pcba加(jia)工(gong)(gong)(gong)工(gong)(gong)(gong)藝打樣(yang)的(de)(de)好(hao)處之一就是(shi)提高了生(sheng)產(chan)力，并(bing)且(qie)提高了生(sheng)產(chan)加(jia)工(gong)(gong)(gong)速度。無論(lun)是(shi)外包形式生(sheng)產(chan)加(jia)工(gong)(gong)(gong)pcba加(jia)工(gong)(gong)(gong)工(gong)(gong)(gong)藝板還是(shi)企業自(zi)(zi)己的(de)(de)生(sheng)產(chan)部門先完成打樣(yang)再進(jin)行批量(liang)生(sheng)產(chan)，就相當(dang)于把(ba)完成的(de)(de)成品提前做出來并(bing)且(qie)查(cha)漏補缺修改成合格(ge)品，再以此(ci)為樣(yang)批量(liang)加(jia)工(gong)(gong)(gong)生(sheng)產(chan)，其效率自(zi)(zi)然就會提高很多(duo)。

SMT來(lai)料(liao)加(jia)(jia)工(gong)(gong)(gong)是(shi)指電(dian)子(zi)委托(tuo)方因(yin)自身設備和技術經驗的(de)不(bu)足(zu)等原因(yin)，貼(tie)片(pian)加(jia)(jia)工(gong)(gong)(gong)焊(han)接，提供物(wu)料(liao)至(zhi)電(dian)子(zi)加(jia)(jia)工(gong)(gong)(gong)方，進(jin)行PCB加(jia)(jia)工(gong)(gong)(gong)生(sheng)產。SMT加(jia)(jia)工(gong)(gong)(gong)周期(qi)一(yi)般(ban)在3天左右(you)。SMT來(lai)料(liao)加(jia)(jia)工(gong)(gong)(gong)因(yin)不(bu)需加(jia)(jia)工(gong)(gong)(gong)進(jin)行物(wu)料(liao)采購(gou)，貼(tie)片(pian)加(jia)(jia)工(gong)(gong)(gong)價格，因(yin)此，其加(jia)(jia)工(gong)(gong)(gong)費用主要是(shi)由焊(han)點多少及PCB板的(de)復雜難度來(lai)決定(ding)。過(guo)小(xiao)批(pi)量生(sheng)產則會收取一(yi)定(ding)的(de)工(gong)(gong)(gong)程費用。SMT來(lai)料(liao)加(jia)(jia)工(gong)(gong)(gong)雖是(shi)PCBA的(de)基礎加(jia)(jia)工(gong)(gong)(gong)，但是(shi)其工(gong)(gong)(gong)藝要求還是(shi)比較(jiao)嚴(yan)格的(de)，有能(neng)力(li)的(de)電(dian)子(zi)加(jia)(jia)工(gong)(gong)(gong)廠家可以很好的(de)確保其質(zhi)量。
