style="text-indent:25px">SMT貼片指的是在PCB基礎(chǔ)上進行加工的系列工藝流程的簡稱。PCB為印刷電路板。SMT是表面組裝技術(shù)（表面貼裝技術(shù)），是電子組裝行業(yè)里比較流行的一種技術(shù)和工藝。電子電路表面組裝技術(shù)，稱為表面貼裝或表面安裝技術(shù)。它是一種將無引腳或短引線表面組裝元器件（簡稱SMC/SMD，中文稱片狀元器件）安裝在印制電路板的表面或其它基板的表面上，通過再流焊或浸焊等方法加以焊接組裝的電路裝連技術(shù)。在通常情況下我們用的電子產(chǎn)品都是由pcb加上各種電容，電阻等電子元器件按設(shè)計的電路圖設(shè)計而成的,所以各種各樣的電器需要各種不同的SMT貼片加工工藝來加工。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。</p><p style="text-indent:25px">清潔時不要將酒精酒在SMT貼片機的吸嘴標(biāo)記上。如果不小心灑上了，需要立即將其擦去。清潔吸嘴后，一定要再涂上硅酮潤滑油。將少量硅酮潤滑油涂在吸墊的外表面上，然后再用干布擦去潤滑油，可防止橡膠吸墊變質(zhì)。檢査空氣壓力，這一步主要檢查真空排出管的性能。首先打開真空閥門，然后用手指堵住吸嘴頂部，查看負壓是否大于0.08MPa（600mmHg）。SMT貼片機械潤滑：對以下部件每月進行一次潤滑。X軸球形螺釘，X軸引導(dǎo)器；y軸引導(dǎo)器、引導(dǎo)軸、球形螺釘、調(diào)節(jié)螺釘；傳輸導(dǎo)軌引導(dǎo)軸；貼裝頭球形螺桿、線性通路、潤滑油孔、多槽軸；托盤供料器的球形螺釘、滑動組件、多槽軸。SMT貼片工藝中，首先對物料進行檢驗，檢查物料的用量、規(guī)格、型號、品質(zhì)、性能是否符合要求。</p><div

style="text-indent:25px">SMT貼片加工中造成空洞、裂紋的原因很多，主要有以下方面因素：1、焊接面（PCB焊盤與元件焊端表面）存在浸潤不良；2、焊料氧化；3、焊接面各種材料的膨脹系數(shù)不匹配，焊點凝固時不平穩(wěn)；4、再流焊溫度曲線的設(shè)置未能使焊音中的有機揮發(fā)物及水分在進入回流區(qū)前揮發(fā)。無鉛焊料的問題是高溫、表面張力大、黏度大。表面張力的增加勢必會使氣體在冷卻階段的外逸更困難，氣體不容易排出來，使空洞的比例增加。因此，SMT貼片中無鉛焊點中的氣孔、空洞比較多。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。鎮(zhèn)江貼片加工廠價格</p><p

style="text-indent:25px">在SMT貼片加工的日常工作中，我們經(jīng)常會遇到一些做電力電子、電源、工業(yè)控制、充電樁的產(chǎn)品。上面大多數(shù)都是DIP插件物料，而且很多的物料因為跟貼片物料的耐溫性和加工要求不一致，就需要用到手工焊接，特別是常見的翼形引腳元件比較常見。一般情況下如果是不能機貼的話，會選擇用人工手焊的形式把之后剩余的幾個料焊接上去。那么翼形引腳的手工焊接方法您了解多少呢？一、逐個焊點焊接：1、用鑷子夾持器件，對準(zhǔn)方向使引腳與PCB焊盤對齊，居中貼放在相應(yīng)的焊盤上。2、選用圓錐形或鑿子形烙鐵頭，焊牢器件斜對角1~2個引腳。3、從引腳開始、順序逐個焊點焊接，同時加少許直徑0.5mm（或更細一些）的焊錫絲，將器件兩側(cè)或四周引腳全部焊牢。窄間距時，不容易控制焊錫絲的送入量，因此也可以涂助焊劑，然后用轉(zhuǎn)移法逐個焊點焊接。二、拖焊法：1、用鑷子夾持器件，對準(zhǔn)極性和方向，使引腳與焊盤對齊，居中貼放在相應(yīng)的焊盤上，用圓錐或鑿子形烙鐵頭先焊牢器件斜對角1~2個引腳。2、涂助焊劑。3、給烙鐵頭上錫。4、從引腳開始、順序向下緩慢勻速拖拉烙鐵，將器件兩側(cè)全部焊牢。中山大批量SMT貼片設(shè)備</p></p><br
