style="text-indent:25px">在SMT貼片加工的日常工作中，我們經(jīng)常會(huì)遇到一些做電力電子、電源、工業(yè)控制、充電樁的產(chǎn)品，上面大多數(shù)都是DIP插件物料，而且很多的物料因?yàn)楦N片物料的耐溫性和加工要求不一致，就需要用到手工焊接，特別是常見的翼形引腳元件比較常見。一般情況下如果是不能機(jī)貼的話，會(huì)選擇用人工手焊的形式把之后剩余的幾個(gè)料焊接上去。那么翼形引腳的手工焊接方法您了解多少呢？一、逐個(gè)焊點(diǎn)焊接：1、用鑷子夾持器件，對(duì)準(zhǔn)方向使引腳與PCB焊盤對(duì)齊，居中貼放在相應(yīng)的焊盤上，江蘇smt專業(yè)貼片加工公司。2、選用圓錐形或鑿子形烙鐵頭，焊牢器件斜對(duì)角1~2個(gè)引腳。3、從***條引腳開始、順序逐個(gè)焊點(diǎn)焊接，同時(shí)加少許直徑0.5mm（或更細(xì)一些）的焊錫絲，將器件兩側(cè)或四周引腳全部焊牢。窄間距時(shí)，不容易控制焊錫絲的送入量，因此也可以涂助焊劑，然后用轉(zhuǎn)移法逐個(gè)焊點(diǎn)焊接，江蘇smt專業(yè)貼片加工公司。二、拖焊法：1、用鑷子夾持器件，對(duì)準(zhǔn)極性和方向，使引腳與焊盤對(duì)齊，居中貼放在相應(yīng)的焊盤上，用圓錐或鑿子形烙鐵頭先焊牢器件斜對(duì)角1~2個(gè)引腳，江蘇smt專業(yè)貼片加工公司。2、涂助焊劑。3、給烙鐵頭上錫。4、從***條引腳開始、順序向下緩慢勻速拖拉烙鐵，將器件兩側(cè)全部焊牢。在SMT貼片加工中，隨著PCBA電路板的集成度越來越高，集成電路的內(nèi)絕緣層越來越薄。江蘇smt專業(yè)貼片加工公司</p><div

1、用自動(dòng)上板機(jī)，或人工把PCB輕輕放在傳送帶（或夾具）上，機(jī)器自動(dòng)完成噴涂助焊劑、干燥、預(yù)熱、波峰焊、冷卻等操作。2、在波峰焊出口處接住PCB。3、按照行業(yè)標(biāo)準(zhǔn)《焊點(diǎn)質(zhì)量評(píng)定》SJ/T10666-1995或IPC-A-610E進(jìn)行首件焊接質(zhì)量檢驗(yàn)。根據(jù)首件焊接結(jié)果調(diào)整焊接參數(shù)，直到質(zhì)量符合要求后才能進(jìn)行連續(xù)批量生產(chǎn)。PCBA首件檢驗(yàn)我們之前就已經(jīng)反復(fù)強(qiáng)調(diào)過，其重要性不言而喻。為什么說在波峰焊后要進(jìn)行首件檢測呢？其實(shí)PCBA的主要生產(chǎn)流程包括：錫膏印刷、SMT貼片、回流焊焊接、DIP插件、波峰焊焊接。如果沒有問題的話，經(jīng)過了波峰焊焊接的電路板就可以拿回去組裝成完成品了。那么如果我們對(duì)一個(gè)已經(jīng)走完了生產(chǎn)流程的產(chǎn)品不加檢驗(yàn)就去生產(chǎn)，如果出現(xiàn)品質(zhì)異常，那么已經(jīng)組裝好的產(chǎn)品也要拆下來重新返修。所以除非是客戶明確表示不用做首件檢測的情況，其余情況下，PCBA加工廠一定要在波峰焊接完成之后進(jìn)行首件檢測，經(jīng)過檢驗(yàn)合格之后跟客戶確認(rèn)，下一步在進(jìn)行量產(chǎn)和批量生產(chǎn)才是一個(gè)可行的方案。無錫正規(guī)smt貼片SMT貼片的加工流程介紹。</p><div

1.貼裝頭：空氣通道一為了保證機(jī)器的精確性和安裝速度，要求定期清潔空氣通道（從空氣過濾組件到吸嘴托進(jìn)行吹氣）?？諝膺^濾器一一每星期將空氣過濾器從空氣過濾組件中拿出一次，査看其污染情況。如果被灰塵堵塞，予以更換。 2.吸嘴：如果吸嘴有污物，如焊料，堵在吸嘴里，吸氣就不會(huì)有力。如果在吸嘴的底面有污物，會(huì)造成漏氣，同時(shí)造成進(jìn)行圖像處理時(shí)，系統(tǒng)不能識(shí)別較小的元件。用酒精清潔吸嘴，用吹風(fēng)機(jī)吹去灰塵（每周至少一次）。檢查橡膠吸墊是否有裂縫和污染。SMT貼片加工中出現(xiàn)的連錫，漏焊等各種工藝問題。</p><div

style="text-indent:25px">SMT貼片加工焊接后的清洗是指利用物理作用、化學(xué)反應(yīng)的方法去除SMT再流焊、波峰焊和手工焊后殘留在表面組裝板表面的助焊劑殘留物及貼片加工組裝工藝過程中造成的污染物、雜質(zhì)的工序污染物對(duì)表面組裝板的危害 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(shí)，極性殘留物的離子就會(huì)朝極性相反的導(dǎo)體遷移，嚴(yán)重時(shí)會(huì)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(duì)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(shí)會(huì)導(dǎo)電，引起短路或斷路。江蘇smt專業(yè)貼片加工公司</p><p
