style="text-indent:25px">SMT貼片膠的工藝特性：連接強(qiáng)度：SMT貼片膠必須具備較強(qiáng)的連接強(qiáng)度，在被硬化后，即使在焊料熔化的溫度也不剝離。點(diǎn)涂性：目前對印制板的分配方式多采用點(diǎn)涂方式，因此要求膠要具有以下性能：①適應(yīng)各種貼裝工藝；②易于設(shè)定對每種元器件的供給量；③簡單適應(yīng)更換元器件品種；④點(diǎn)涂量穩(wěn)定。適應(yīng)高速機(jī)：現(xiàn)在使用的貼片膠必須滿足點(diǎn)涂和高速貼片機(jī)的高速化，具體講，就是高速點(diǎn)涂無拉絲，再者就是高速貼裝時，印制板在傳送過程中，貼片膠的粘性要保證元器件不移動。拉絲、塌落：貼片膠一旦沾在焊盤上，元器件就無法實(shí)現(xiàn)與印制板的電氣性連接，所以，貼片膠必須是在涂布時無拉絲、涂布后無塌落，以免污染焊盤。</p><p style="text-indent:25px">SMT貼片選擇合適的封裝，其優(yōu)點(diǎn)主要是：1）有效節(jié)省PCB面積；2）提供更好的電學(xué)性能；3）對元器件的內(nèi)部起保護(hù)作用，免受潮濕等環(huán)境影響；4）提供良好的通信聯(lián)系；5）幫助散熱并為傳送和測試提供方便。表面安裝元器件選?。罕砻姘惭b元器件分為有源和無源兩大類。按引腳形狀分為鷗翼型和“J”型。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，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、抗素沖擊性和抗震性好、寄生損耗小，被廣泛應(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。SMT貼片加工技術(shù)是實(shí)現(xiàn)電子產(chǎn)品小型化、高集成不可缺少重要貼裝工藝。</p><div

style="text-indent:25px">制作首件時發(fā)現(xiàn)時實(shí)物與SMT貼片位置圖的參數(shù)不一致時，首先我們先核對其原始BOM，查一下到底是哪一個環(huán)節(jié)出錯，如果是SMT貼片位置圖問題，馬上反饋給品質(zhì)相關(guān)人員處。如果是工程程式打錯，則通知工程更換程序。更正之后需再次核對整塊板。紅膠板要測試其拉力。測試OK的板正常過爐之后，我們需檢查其焊接效果。當(dāng)正常生產(chǎn)時，如果同一位置或同一種缺陷多次出現(xiàn)時，我們應(yīng)立即通知工程改善，并監(jiān)督改善情況。正常情況下一訂單只做一次首件并保留到清尾。SMT貼片有良好的潤濕性，焊接點(diǎn)的邊緣應(yīng)當(dāng)較薄。SMT貼片設(shè)備</p><p
