style="text-indent:25px">隨著電子行業(yè)的不斷進(jìn)步發(fā)展，SMT表面組裝技術(shù)也愈加成熟，設(shè)備和功能也在不斷完善，SMT貼片加工技術(shù)已經(jīng)逐漸取代傳統(tǒng)插裝技術(shù)，成為電子組裝行業(yè)里非常流行的一種工藝技術(shù)。SMT貼片加工技術(shù)為什么會如此流行呢？一起來看看它的特點就知道了，珠海定制SMT貼片工藝。一、電子產(chǎn)品體積小，組裝密度高SMT貼片元件的體積*為傳統(tǒng)封裝元件的10%左右，重量也只為傳統(tǒng)插裝元件的10%。SMT技術(shù)通常可使電子產(chǎn)品的體積減少40%~60%，使質(zhì)量減少60%~80%，面積和重量都大幅度減少。SMT貼片加工組裝元件網(wǎng)格已從1，珠海定制SMT貼片工藝，珠海定制SMT貼片工藝.27mm發(fā)展到目前的0.63mm網(wǎng)格，部分已達(dá)到0.5mm網(wǎng)格。采用通孔安裝技術(shù)，可提高組裝密度。SMT貼片加工廠在貼片加工中需要注意哪些環(huán)節(jié)?珠海定制SMT貼片工藝</p><div

style="text-indent:25px">SMT貼片工藝中，首先對物料進(jìn)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；接著刷錫膏，錫膏需要解凍、拌勻，鋼網(wǎng)調(diào)校、錫膏印刷、檢查膏面均勻?qū)φ?；接著使用貼片機進(jìn)行貼片工藝，需要注意位置、型號、方向、極性、整齊度；為了保證PCB板的品質(zhì)，新品檢員必須以無錯件、錯極、漏件、錯位的高標(biāo)準(zhǔn)要求檢查PCB板的貼面，錫膏必須均勻著附好，元件必須高低平整對齊；其次將經(jīng)檢驗合格的PCB板過回流焊，進(jìn)行250°高溫凝固也就是俗稱回流焊，貼片完成后還要進(jìn)行AOI的影像檢測，避免在SMT貼片中造成的錯料混料假焊。浙江貼片smt廠SMT貼片選擇合適的封裝，其優(yōu)點主要是：有效節(jié)省PCB面積。</p><div

style="text-indent:25px">貼片膠的流動性過大會引起塌落，塌落常見問題是點涂后放置過久會引起塌落，如果貼片膠擴展到印制線路板的焊盤上會引起焊接不良。而且塌落的貼片膠對那些引腳相對較高的元器件來講，它接觸不到元器件主體，會造成粘接力不足，因此易于塌落的貼片膠，其塌落率很難預(yù)測，所以它的點涂量的初始設(shè)定也很困難。針對這一點，我們只好選擇那些不容易塌落的也就是搖溶比較高的貼片膠。對于點涂后放置過久引起的塌落，我們可以采用在點涂后的短時間內(nèi)完成貼片膠裝、固化來加以避免。</p><p style="text-indent:25px">SMT其實離我們每個人的實際生活都很近，我們早上去上班坐公交用的IC卡，上班進(jìn)公司打上班卡用的設(shè)備，都是SMT加工出來的，還有我們每個人每天都離不開的手機，電腦，平板，都是SMT做出來的，手機越來越薄，重量越來越清，也得益于SMT技術(shù)的更新?，F(xiàn)代人生活的方方面面都與SMT有著千絲萬縷的聯(lián)系。那么何為SMT貼片呢?SMT對于大多數(shù)人來說很陌生，很多人都不知道SMT是什么?也感覺跟他們的生活沒有關(guān)系，正因如此人們對SMT知之甚少。SMT就是表面組裝技術(shù)(SurfaceMountedTechnology的縮寫),是目前電子組裝行業(yè)里非常流行的一種技術(shù)和工藝。加工SMT貼片過程中就需要了解元器件移位的原因，并針對性進(jìn)行解決。</p><div

style="text-indent:25px">SMT貼片膠的使用目的：①波峰焊中防止元器件脫落(波峰焊工藝)。在使用波峰焊時，為防止印制板通過焊料槽時元器件掉落，而將元器件固定在印制板上。②再流焊中防止另一面元器件脫落(雙面再流焊工藝)。雙面再流焊工藝中，為防止已焊好的那一面上大型器件因焊料受熱熔化而脫落，要使有SMT貼片膠。③防止元器件位移與立處(再流焊工藝、預(yù)涂敷工藝)。用于再流焊工藝和預(yù)涂敷工藝中防止貼裝時的位移和立片。④作標(biāo)記(波峰焊、再流焊、預(yù)涂敷)。此外，印制板和元器件批量改變時，用貼片膠作標(biāo)記。SMT貼片加工根據(jù)產(chǎn)品類型不同，貼片價格也是不相同的，在工藝流程上也是有所區(qū)別。上海貼片加工廠價格</p><p style="text-indent:25px">SMT貼片加工要求各裝配位號元器件的類型、型號和極性等特征標(biāo)記要符合產(chǎn)品的裝配圖和BOM表要求。珠海定制SMT貼片工藝</p><p style="text-indent:25px">在SMT貼片機上對優(yōu)化好的產(chǎn)品程序進(jìn)行編輯：①調(diào)出優(yōu)化好的程序。②做 PCB MarK和局部Mak的 Image圖像。③對沒有做圖像的元器件做圖像，并在圖像庫中登記。④對未登記過的元器件在元件庫中進(jìn)行登記。⑤對排放不合理的多管式振動供料器，根據(jù)器件體的長度進(jìn)行重新分配，盡量把器件體長度比較接近的器件安排在同一個料架上：并將料站持放得緊一點，中間盡量不要有空閑的料站，這樣可縮短拾元件的路程。⑥把程序中外形尺較大的多引腳、窄間距器件，如160條引腳以上的QFP，大尺寸的PLCC、BGA，以及長插座等改為 Single Pickup單個拾片方式，這樣可提高貼裝精度。⑦存盤檢查是否有錯誤信息，根據(jù)錯誤信息修改程序，直至存盤后沒有錯誤信息為止。珠海定制SMT貼片工藝</p></p><br /><p>文章來源地址: http://www.cdcfah.com/cp/2528565.html</p></div></div></div></div></div><div id="lpmeqxj"
