1、焊劑和焊音中添加的活化劑帶有少量西化物、酸或鹽，焊接后形成極性殘留物履蓋在焊點(diǎn)表面。當(dāng)電子產(chǎn)品加電時，極性殘留物的離子就會朝極性相反的導(dǎo)體遷移，嚴(yán)重時會引起短路。 2、目前常用焊劑中的鹵化物、氯化物具有很強(qiáng)的活性和吸濕性，在湘濕的環(huán)境中對基板和焊點(diǎn)產(chǎn)生腐蝕作用，使基板的表面絕緣電阻下降并產(chǎn)生電遷移，嚴(yán)重時會導(dǎo)電，引起短路或斷路。北京小型smt貼片機(jī)SMT貼片加工技術(shù)目前已普遍應(yīng)在電子行業(yè)中。</p><div

1、SMT貼片技術(shù)員佩戴好檢驗(yàn)OK的靜電環(huán)，插件前檢查每個訂單的電子元件無錯/混料、破損、變形、劃傷等不良現(xiàn)象 2、電路板的插件板需要提前把電子物料準(zhǔn)備好，注意電容極性方向須正確無誤 3、SMT印刷作業(yè)完畢后進(jìn)行無漏插、反插、錯位等不良產(chǎn)品的檢查，將良好的上錫完成品流入下一工序。 4、SMT貼片組裝作業(yè)前請配戴靜電環(huán),金屬片緊貼手腕皮膚并保持接地良好,雙手交替作業(yè)。 5、?USB/IF座子/屏蔽罩/高頻頭/網(wǎng)口端子等金屬元件,插件時須戴手指套作業(yè)。 6、所插元器件位置、方向須正確無誤,元件平貼板面,架高元件必須插到K腳位置。 7、如有發(fā)現(xiàn)物料與SOP以及BOM表上規(guī)格不一致時,須及時向班/組長報告。 8、物料需輕拿輕放不可將經(jīng)過SMT前期工序的PCB板掉落而導(dǎo)致元件受損,晶振掉落不可使用。 9、上下班前請將工作臺面整理干凈,并保持清潔。 10、嚴(yán)格遵守作業(yè)區(qū)操作規(guī)則，首件檢測區(qū)、待檢區(qū)、不良區(qū)、維修區(qū)、少料區(qū)的產(chǎn)品嚴(yán)禁私自隨意擺放，上下班交接要注明未完工序。</p><p 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貼片表面需要完整而平滑光亮，不能有缺陷。</p><div

style="text-indent:25px">IPQC需利用電橋（LCR表）、萬用表和貼片位置圖來檢查首件，用電橋測量電容和0402電阻的容值、阻值是否與BOM一致，再檢查元器件的絲印、方向是否與stm貼片位置圖一致。在測試首件過程中，我們用貼片位置圖（必須是執(zhí)行較新ECN的）上的參數(shù)來核對PCB上元器件的參數(shù)。所有的電容需用LCR表測試，在測的時候盡量按同一個方向測試，以免有漏測現(xiàn)象。如是0402的電阻也需用LCR表測試，大于0402的電阻及其它物料需核對其絲印、方向是否正確，物料的方向一般以PCB板方向?yàn)闃?biāo)準(zhǔn)（如果貼片位置圖的方向與PCB的方向不一致時，需找相關(guān)人員確認(rèn)），確保無多料、少料、錯件、錯位、反向、移位等不良現(xiàn)象。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。北京小型smt貼片機(jī)</p><p style="text-indent:25px">SMT貼片機(jī)的維護(hù)和保養(yǎng)是整個PCBA制造工序中的重要事情。北京正規(guī)smt貼片</p><p style="text-indent:25px">對于直接接觸stm貼片產(chǎn)品的操作人員，要戴防靜電手腕帶，并要求戴防靜電手腕帶的操作人員每天上、下年上班前各測試一次，以保證手腕帶與人體的良好接觸。同時，每天安排相關(guān)人員監(jiān)督檢查，并對員工進(jìn)行貼片加工防靜電方面的知識培訓(xùn)和現(xiàn)場管理。生產(chǎn)過程中手拿產(chǎn)品時，*能拿產(chǎn)品邊緣無電子元器件處;生產(chǎn)后產(chǎn)品必須裝在防靜電包裝中;安裝時，要求一次拿一塊產(chǎn)品，不允許一次拿多塊產(chǎn)品。SMT加工廠在返工操作時，必須將要修理的產(chǎn)品放在防靜電裝置中.再拿到返修工位。整個生產(chǎn)過程中用到的設(shè)備和工具都應(yīng)具有防靜電能力。SMT貼片加工之后經(jīng)過測試驗(yàn)收合格的產(chǎn)品，應(yīng)用離子噴槍噴射一次再包裝起來。北京正規(guī)smt貼片</p><p
