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，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。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
