1、生產(chǎn)車間的溫濕度。根據(jù)電子加工車間的行業(yè)標(biāo)準(zhǔn)，它規(guī)定了SMT加工廠的環(huán)境溫度值在25±3℃之間，濕度值在：0.01%RH之間。因為整個加工過程中有很多的精密元器件，對溫濕度極其敏感。同時相對的濕度對靜電的管控和處理有非常大的益處，鎮(zhèn)江貼片電解，鎮(zhèn)江貼片電解。 2、專業(yè)的操作人員。因為SMT這個環(huán)節(jié)的工序流程必須要細(xì)致，所有工序看起來很簡單。但是如果不是很熟練的操作員就容易出現(xiàn)因為細(xì)節(jié)管控不到位導(dǎo)致SMT焊點可靠性不高、焊點缺陷率高，鎮(zhèn)江貼片電解。因此SMT貼片機需要經(jīng)過專業(yè)的培訓(xùn)之后才能正式上崗。經(jīng)過培訓(xùn)上崗的員工不僅能夠提高生產(chǎn)效率，而且還能提高良品率。SMT貼片加工過程中有時會出現(xiàn)一些工藝問題。鎮(zhèn)江貼片電解</p><div

style="text-indent:25px">SMT貼片指的是在PCB基礎(chǔ)上進(jìn)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,所以形形**的電器需要各種不同的SMT貼片加工工藝來加工?。</p><p style="text-indent:25px">SMT貼片加工中施加焊膏的工藝要求：1、施加的焊膏量均勻，一致性好。焊膏圖形要消晰，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。2、在一般情況下，焊盤上單位面積的焊膏量應(yīng)為0.8mg/mm3左右:對卒間距元器件，應(yīng)為0.5mgmm2左右。3、印刷在基板上的焊膏，與希望重量值相比，可允許有一定的偏差，至于焊膏覆蓋每個焊盤的面積，應(yīng)在75％以上。采用免清洗技術(shù)時，要求焊膏全部位于焊盤上，無鉛要求焊膏完全覆蓋焊盤。4、焊膏印刷后，應(yīng)無嚴(yán)重塌落，邊像整齊，錯位不大于02mm對容間距元器件焊盤，錯位不大于O0lm?；灞砻娌辉试S被焊膏污染。采用免清洗技術(shù)時，可通過縮小模板開口尺寸的方法，使焊膏全部位于焊盤上。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。</p><div

style="text-indent:25px">隨著SMT貼片加工的飛速發(fā)展,不但元器件的尺寸越來越小、SMT貼片元件密度越來越高,而且還不斷推出新型封裝形式,為了適應(yīng)高密度、高難度的電路板組裝技術(shù)的需要,貼裝機正在向高速度、高精度、多功能和模塊化、智能化方向發(fā)展。貼片加工設(shè)備的高速度：1.“飛行對中”技術(shù)。飛行對中技術(shù)把CCD圖像傳感器直接安裝在貼裝頭上,一起運動,實現(xiàn)了在拾起器件后,在運動到印制電路板貼裝位置的過程中對元件進(jìn)行光學(xué)對中。2.高速SMT貼片機模塊化。3.雙路輸送結(jié)構(gòu)。在保留傳統(tǒng)單路貼裝機的性能下,將PCB的輸送、定位、檢測等設(shè)計成雙路結(jié)構(gòu),這種雙路結(jié)構(gòu)的貼裝機,其工作方式可分為同步方式和異步方式。同步方式運轉(zhuǎn)時,完成兩塊大小相同的印制板的器件貼裝;異步方式運轉(zhuǎn)時,當(dāng)一塊印制板在進(jìn)行器件貼裝時,另一塊印制板完成傳送、基準(zhǔn)對準(zhǔn)、壞板檢查等步驟,從而提高SMT加工廠的生產(chǎn)效率。雙面SMT貼片：雙面PCB板是兩面都有布線，必須要在兩面間有適當(dāng)?shù)碾娐愤B接才行。鎮(zhèn)江貼片電解</p><p
