style="text-indent:25px">SMT貼片加工注意事項(xiàng)：SMT屬于表面組裝的一項(xiàng)技術(shù)，現(xiàn)階段電子組裝行業(yè)比較流行的技術(shù)，SMT貼片加工主要指把元件通過貼處設(shè)備貼到印有膠或錫膏的PCB上，然后過焊接爐。SMT貼片加工以組裝密度高、電子產(chǎn)品體積小、高頻特性好等優(yōu)點(diǎn)得到廠家認(rèn)可，因?yàn)镾MT貼片機(jī)的工作效率和穩(wěn)定的性能為我們的生產(chǎn)帶來了極大的優(yōu)勢(shì)，有了SMT貼片機(jī)，就能提高生產(chǎn)效率和能提供高質(zhì)量的產(chǎn)品給顧客。SMT貼片機(jī)相當(dāng)于一個(gè)貼片機(jī)器人，是比較精密的自動(dòng)化生產(chǎn)設(shè)備，貼片阻容元件可以先在一個(gè)焊點(diǎn)上點(diǎn)錫，再放上元件的一頭，用鑷子夾著元件，焊上一頭后看下是否放正了，若已經(jīng)放正即可焊上另一頭。</p><p style="text-indent:25px">貼片加工和焊接檢測(cè)是對(duì)焊接產(chǎn)品的檢測(cè)。一般需要檢測(cè)的點(diǎn)有：檢測(cè)點(diǎn)焊表面是否光潔，有無孔洞、孔洞等；點(diǎn)焊是否呈月牙形，有無多錫少錫，有無立碑、橋梁、零件移動(dòng)、缺件、錫珠等缺陷。各部件是否有不同水平的缺陷；搜查焊接時(shí)是否有短路、導(dǎo)通等缺陷，檢查印刷電路板表面的顏色變化。在貼片加工過程中，要保證印刷電路板的焊接質(zhì)量，必須始終注意回流焊工藝參數(shù)是否合理。如果參數(shù)設(shè)置有問題，則無法保證印刷電路板的焊接質(zhì)量。因此，在正常情況下，爐溫必須每天測(cè)試兩次，低溫測(cè)試一次。只有不斷完善焊接產(chǎn)品的溫度曲線，設(shè)定焊接產(chǎn)品的溫度曲線，能力擔(dān)保加工產(chǎn)品的質(zhì)量。一般來說smt貼片機(jī)都會(huì)存在拋料問題，而拋料會(huì)產(chǎn)生缺件不良。</p><div
