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，肇慶一站式SMT貼片焊接。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，肇慶一站式SMT貼片焊接。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，肇慶一站式SMT貼片焊接。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。雙面SMT貼片：雙面PCB板是兩面都有布線，必須要在兩面間有適當(dāng)?shù)碾娐愤B接才行。肇慶一站式SMT貼片焊接</p><div

style="text-indent:25px">SMT生產(chǎn)工藝有兩條基本的工藝流程，即焊膏一回流焊工藝和貼片膠一波峰焊工藝。焊膏一回流焊工藝就是先在印制電路板焊盤(pán)上印刷適量的焊膏，再將片式元器件貼放到印制電路板規(guī)定的位置上，之后將貼裝好元器件的印制電路板通過(guò)回流爐完成焊接過(guò)程。這種SMT貼片加工工藝流程主要適用于只有表面組裝元件的組裝。貼片膠一波峰焊工藝就是先在印制電路板焊盤(pán)間點(diǎn)涂適量的貼片膠，再將片式元器件貼放到印制電路板規(guī)定位置上，然后將經(jīng)過(guò)貼片加工好元器件的印制電路板通過(guò)回流爐完成膠水的固化，之后插裝元器件，之后將插裝元器件與表面組裝元器件同時(shí)進(jìn)行波峰焊接。這種工藝流程適用于表面組裝元器件和插裝元器件的混合組裝。佛山專業(yè)SMT貼片流程SMT貼片加工可靠性高、抗振能力強(qiáng)。</p><div
