style="text-indent:25px">SMT是電子元器件的基礎(chǔ)元件之一，稱為表面組裝技術(shù)（或是表面貼裝技術(shù)），分為無引腳或短引線，是通過回流焊或浸焊加以焊接組裝的電路裝連技術(shù)，也是目前電子組裝行業(yè)里流行的一種技術(shù)和工藝。特點(diǎn)：我們的基板，可用于電源供應(yīng)，訊號傳輸、散熱、提供結(jié)構(gòu)的作用。特性：能夠承受固化和焊接的溫度和時間。平整度符合制造工藝的要求。適合返修工作。適合基板的制造工藝。低介質(zhì)數(shù)和高電阻。有利于提高產(chǎn)品的可靠性。此外，SMT工序簡單，焊接較少，適合于自動化生產(chǎn)，生產(chǎn)效率也高，勞動強(qiáng)度低，生產(chǎn)成本降低等優(yōu)點(diǎn)。因此，近年來，SMT得了快速發(fā)展，已成為世界電子整機(jī)組裝技術(shù)的主流。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)。北京批量SMT貼片</p><p 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。北京批量SMT貼片</p><p style="text-indent:25px">無源器件主要包括單片陶瓷電容器、鉭電容器和厚膜電阻器，外形為長方形或園柱形。園柱形無源器件稱為"MELF"，采用再流焊時易發(fā)生滾動，需采用特殊焊盤設(shè)計(jì)，一般應(yīng)避免使用。長方形無源器件稱為"CHIP"片式元器件，它的體積小、重量輕、細(xì)菌素沖擊性和抗震性好、寄生損耗小，被多應(yīng)用于各類電子產(chǎn)品中。為了獲得良好的可焊性，必須選擇鎳底阻擋層的電鍍。表面安裝芯片載體有兩大類:陶瓷和塑料。陶瓷芯片封裝的優(yōu)點(diǎn)是:氣密性好，對內(nèi)部結(jié)構(gòu)有良好的保護(hù)作用，信號路徑較短，寄生參數(shù)、噪聲、延時特性明顯改善，降低功耗。缺點(diǎn)是因?yàn)闊o引腳吸收焊膏溶化時所產(chǎn)生的應(yīng)力，封裝和基板之間CTE失配可導(dǎo)致焊接時焊點(diǎn)開裂。常用的陶瓷餅片載體是無引線陶瓷習(xí)片載體LCCC。北京批量SMT貼片</p><p
