style="text-indent:25px">在SMT貼片加工過程中要用到多種檢測設(shè)備，以在線或離線的形式工作，以達到產(chǎn)品的制造、檢驗的要求。為了保證產(chǎn)品制造過程中的質(zhì)量，檢測設(shè)備的準(zhǔn)備非常重要。檢測設(shè)備：1.AOI的準(zhǔn)備內(nèi)容:檢查運行狀態(tài)，天津貼片元器件，工藝文件，檢測程序，SMT技術(shù)員設(shè)置工藝參數(shù)，光源，運行記錄等。2.ICT的準(zhǔn)備內(nèi)容:檢查運行狀態(tài)、工藝文件，檢測程序，設(shè)置工藝參數(shù)，運行記錄，針床夾具等。3，天津貼片元器件.AM的準(zhǔn)備內(nèi)容:檢査運行狀態(tài)，天津貼片元器件，工藝文件，檢測程序，設(shè)置工藝參數(shù)，防輻射，運行記錄等。SMT貼片工廠中，我們大多數(shù)的企業(yè)常用的錫膏合金主要成份為Sn/Pb合金，且合金進行比例為63/37。天津貼片元器件</p><div

2、Mark圖形放在模板的哪一面，應(yīng)根據(jù)印刷機具體構(gòu)造(攝像機的位置)而定。 3、Mark點刻法視印刷機而定，有印刷面、非印刷面、兩面半刻，全刻透封黑膠等。 4、是否拼板，以及拼板要求。如果拼板，應(yīng)給出拼板的PCB文件。插裝焊盤環(huán)的要求。由于插裝元器件采用再流焊工藝時，比貼裝元器件要求較多的焊膏量，因此如果有插裝元器件需要采用再流焊工藝時，可提出特殊要求。天津貼片元器件隨著SMT貼片無鉛化的發(fā)展，近來在傳統(tǒng)氣相焊設(shè)各的基礎(chǔ)上開發(fā)了學(xué)生一種可以基于噴射系統(tǒng)原理的新方法。</p><div

style="text-indent:25px">SMT貼片涂敷工藝及設(shè)備：SMT貼片進行涂敷的主要目的是將膠水或焊膏精確地涂敷于PCB上，使貼片工序貼裝的元器件能夠粘在PCB焊盤上。按照涂數(shù)方式的不同表面涂數(shù)工藝可分為以下幾種。根據(jù)SMT貼片加工焊膏與貼片膠組成成分的不同，焊膏涂敷通常采用模板絲網(wǎng)印刷工藝、噴涂工藝、點涂工藝，貼片膠涂敷通常采用注射點涂工藝、針式轉(zhuǎn)移工藝、絲網(wǎng)模板印刷工藝，二者的優(yōu)先選擇順序也分別是模板絲網(wǎng)印工藝和注射點涂工藝。焊膏或貼片膠涂敷時，SMT加工廠大批量生產(chǎn)一般使用大型自動化設(shè)備，諸如，印刷機、點膠機、點膏機等。小批量或手工涂敷時，通常采用臺式點膠或點膏機、臺式印劇機甚至手工涂敷。天津貼片元器件</p><p
