style="text-indent:25px">SMT貼片加工模板制作工藝要求：Mark的處理步驟規(guī)范有哪些？ 1、Mark的處理方式，是否需要Mark，放在模板的那一面等。 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。SMT貼片加工技術(shù)是實現(xiàn)電子產(chǎn)品小型化、高集成不可缺少重要貼裝工藝。</p><div

style="text-indent:25px">SMT貼片加工中出現(xiàn)元器件移位的原因是什么？1.錫膏本身的粘性不夠，元器件在搬運時發(fā)生振蕩、搖晃等問題而造成了元器件移位。2、焊膏中焊劑含量太高，在回流焊過程中過多的焊劑的流動導致了元器件的移位。3、元器件在印刷、貼片后的搬運過程中由于振動或是不正確的搬運方式引起了元器件移位。4、貼片加工時，吸嘴的氣壓沒有調(diào)整好，壓力不夠，造成元器件移位。5、貼片機本身的機械問題造成了元器件的安放位置不對。SMT貼片加工中一旦出現(xiàn)元器件移位，就會影響電路板的使用性能，因此在加工過程中就需要了解元器件移位的原因，并針對性進行解決。北京電子</p><p
