style="text-indent:25px">施加焊膏要求：施加的焊膏量均勻，一致性好。焊膏圖形要清晰，相鄰的圖形之間盡量不要粘連。焊膏圖形與焊盤圖形要一致，盡量不要錯位。在—般情況下，焊盤上單位面積的焊膏量應為0.8mg/mm2左右。對窄間距元器件，應為0.5mg/mm2左右(在實際操作中用模板厚度與開口尺寸來控制)。印刷在PCB上的焊膏重量與設計要求的重量值相比，可允許有一定的偏差，焊膏覆蓋每個焊盤的面積，應在75%以上。焊膏印刷后，應無嚴重塌落，邊緣整齊，錯位不大于0.2mm，對窄間距元器件焊盤，錯位不大于0.lmm。PCB不允許被焊膏污染。+SMT發(fā)展起來，由于其涉及多學科領(lǐng)域，使其在發(fā)展初期較為緩慢，隨著各學科領(lǐng)域的協(xié)調(diào)發(fā)展。</p><div

style="text-indent:25px">smt貼片加工的優(yōu)點:組裝密度高、電子產(chǎn)品體積小、重量輕，貼片元件的體積和重量只有傳統(tǒng)插裝元件的1/10左右，一般采用SMT之后，電子產(chǎn)品體積縮小40%~60%，重量減輕60%~80%。可靠性高、抗振能力強。焊點缺陷率低。高頻特性好。減少了電磁和射頻干擾。易于實現(xiàn)自動化，提高生產(chǎn)效率。降低成本達30%~50%。節(jié)省材料、能源、設備、人力、時間等。正是由于smt貼片加工的工藝流程的復雜,所以出現(xiàn)了很多的smt貼片加工的工廠,專業(yè)做smt貼片的加工,在深圳,得益于電子行業(yè)的蓬勃發(fā)展,smt貼片加工成就了一個行業(yè)的繁榮。福建專業(yè)SMT貼片電容</p><p
