style="text-indent:25px">SMT生產(chǎn)工藝有兩條基本的工藝流程，即焊膏一回流焊工藝和貼片膠一波峰焊工藝。焊膏一回流焊工藝就是先在印制電路板焊盤上印刷適量的焊膏，再將片式元器件貼放到印制電路板規(guī)定的位置上，之后將貼裝好元器件的印制電路板通過回流爐完成焊接過程。這種SMT貼片加工工藝流程主要適用于只有表面組裝元件的組裝。貼片膠一波峰焊工藝就是先在印制電路板焊盤間點(diǎn)涂適量的貼片膠，再將片式元器件貼放到印制電路板規(guī)定位置上，然后將經(jīng)過貼片加工好元器件的印制電路板通過回流爐完成膠水的固化，之后插裝元器件，之后將插裝元器件與表面組裝元器件同時(shí)進(jìn)行波峰焊接。這種工藝流程適用于表面組裝元器件和插裝元器件的混合組裝。SMT貼片機(jī)的精度和質(zhì)量息息相關(guān)，如果長(zhǎng)時(shí)間不做清理會(huì)造成堵塞氣路，造成氣路不暢。宿遷smt怎么樣</p><p

style="text-indent:25px">當(dāng)焊膏印刷，有必要準(zhǔn)備一個(gè)材料粘貼工具，鋼葉片﹑擦拭紙，氣流成洗滌劑﹑攪拌刀。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。焊料的主要成分粘貼分為兩個(gè)部分的錫粉和助焊劑。助焊劑主要是可以起到有效去除氧化物﹑破壞融錫表面進(jìn)行張力和防止再度發(fā)生氧化的作用。錫膏中錫粉顆粒與助熔劑的體積比約為1：1，重量比約為9：1。SMT加工中錫膏使用前必須經(jīng)過解凍和回溫?cái)嚢璨僮骱蟛拍苁褂??；販夭荒芡ㄟ^使用加熱的方式可以進(jìn)行回溫。PCBA制造中比較容易忽視的一個(gè)環(huán)節(jié)就是“BGA、IC芯片的存儲(chǔ)。芯片的存儲(chǔ)要注意包裝和存放在干燥的環(huán)境中，保持**元器件的干燥和抗氧化。很多非常重要的問題可能大家都會(huì)注意到，但是在一些細(xì)節(jié)的問題上,我們經(jīng)常會(huì)忽視，往往這些也同樣需要SMT貼片加工中需要特別注意。宿遷smt怎么樣</p><p
