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(jiàn)的翼形引腳元件比較常見(jiàn)。一般情況下如果是不能機(jī)貼的話(huà)，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(pán)對(duì)齊，居中貼放在相應(yīng)的焊盤(pán)上。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(kāi)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。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(pán)對(duì)齊，居中貼放在相應(yīng)的焊盤(pán)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。2、涂助焊劑。3、給烙鐵頭上錫。4、從***條引腳開(kāi)始、順序向下緩慢勻速拖拉烙鐵，將器件兩側(cè)全部焊牢。</p><p style="text-indent:25px">SMT貼片波峰焊首件焊接并檢驗(yàn)： 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(guò)，其重要性不言而喻。為什么說(shuō)在波峰焊后要進(jìn)行首件檢測(cè)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(méi)有問(wèn)題的話(huà)，經(jīng)過(guò)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(lái)重新返修。所以除非是客戶(hù)明確表示不用做首件檢測(cè)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(cè)，經(jīng)過(guò)檢驗(yàn)合格之后跟客戶(hù)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。SMT基本工藝：錫膏印刷-->
