style="text-indent:25px">SMT貼片加工中出現(xiàn)元器件移位的原因是什么呢？1.錫膏本身的粘性不夠，元器件在搬運(yùn)時(shí)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(dòng)導(dǎo)致了元器件的移位。3、元器件在印刷、貼片后的搬運(yùn)過程中由于振動(dòng)或是不正確的搬運(yùn)方式引起了元器件移位。4、貼片加工時(shí)，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(jī)本身的機(jī)械問題造成了元器件的安放位置不對(duì)。SMT貼片加工中一旦出現(xiàn)元器件移位，就會(huì)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(duì)性進(jìn)行解決。中山加工SMT貼片流程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(jìn)行比例為63/37。</p><div
