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貼片加工模板制作工藝要求：Mark的處理步驟規(guī)范有哪些？ 1、Mark的處理方式，是否需要Mark，放在模板的那一面等。 2、Mark圖形放在模板的哪一面，應(yīng)根據(jù)印刷機(jī)具體構(gòu)造(攝像機(jī)的位置)而定。 3、Mark點(diǎn)刻法視印刷機(jī)而定，有印刷面、非印刷面、兩面半刻，全刻透封黑膠等。 4、是否拼板，以及拼板要求。如果拼板，應(yīng)給出拼板的PCB文件。插裝焊盤(pán)環(huán)的要求。由于插裝元器件采用再流焊工藝時(shí)，比貼裝元器件要求較多的焊膏量，因此如果有插裝元器件需要采用再流焊工藝時(shí)，可提出特殊要求。SMT貼片加工的優(yōu)點(diǎn):組裝密度高、電子產(chǎn)品體積小、重量輕。</p><div

style="text-indent:25px">制作首件時(shí)發(fā)現(xiàn)時(shí)實(shí)物與SMT貼片位置圖的參數(shù)不一致時(shí)，首先我們先核對(duì)其原始BOM，查一下到底是哪一個(gè)環(huán)節(jié)出錯(cuò)，如果是SMT貼片位置圖問(wèn)題，馬上反饋給品質(zhì)相關(guān)人員處。如果是工程程式打錯(cuò)，則通知工程更換程序。更正之后需再次核對(duì)整塊板。紅膠板要測(cè)試其拉力。測(cè)試OK的板正常過(guò)爐之后，我們需檢查其焊接效果。當(dāng)正常生產(chǎn)時(shí)，如果同一位置或同一種缺陷多次出現(xiàn)時(shí)，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貼片指的是在PCB基礎(chǔ)上進(jìn)行加工的系列工藝流程的簡(jiǎn)稱(chēng)。湖州貼片電解電容廠家</p><p style="text-indent:25px">由于smt貼片加工的工藝流程的復(fù)雜，所以出現(xiàn)了很多的smt貼片加工的工廠。湖州貼片電解電容廠家</p><p style="text-indent:25px">SMT貼片加工中出現(xiàn)元器件移位的原因是什么？1.錫膏本身的粘性不夠，元器件在搬運(yùn)時(shí)發(fā)生振蕩、搖晃等問(wèn)題而造成了元器件移位。2、焊膏中焊劑含量太高，在回流焊過(guò)程中過(guò)多的焊劑的流動(dòng)導(dǎo)致了元器件的移位。3、元器件在印刷、貼片后的搬運(yùn)過(guò)程中由于振動(dòng)或是不正確的搬運(yùn)方式引起了元器件移位。4、貼片加工時(shí)，吸嘴的氣壓沒(méi)有調(diào)整好，壓力不夠，造成元器件移位。5、貼片機(jī)本身的機(jī)械問(wèn)題造成了元器件的安放位置不對(duì)。SMT貼片加工中一旦出現(xiàn)元器件移位，就會(huì)影響電路板的使用性能，因此在加工過(guò)程中就需要了解元器件移位的原因，并針對(duì)性進(jìn)行解決。湖州貼片電解電容廠家</p><p
