style="text-indent:25px">簡(jiǎn)述smt貼片加工中焊接材料的分類(lèi)特點(diǎn)：smt貼片加工中焊料按其組成部分，可以分為錫鉛焊料、銀焊料、銅焊料。按照使用的環(huán)境濕度又可分為高溫焊錫(在高溫下使用的焊錫)和低溫焊錫(在低溫環(huán)境下使用的焊料)。常用的焊錫配比如下：錫60%、鉛40%，熔點(diǎn)182℃;錫50%、鉛32%、鎘18%，熔點(diǎn)150℃;錫55%、鉛42%、鉍23%，熔點(diǎn)150℃。焊料的形狀有圓片、帶狀、球狀、焊錫絲等幾種。常用的焊錫絲，在其內(nèi)部夾有固體助焊劑松香。焊錫絲的直徑種類(lèi)很多，常用的有4mm、3mm、2mm、1.5mm等。</p><p style="text-indent:25px">SMT貼片加工對(duì)環(huán)境的要求、濕度和溫度都是有一定的條件要求，同時(shí)為了保證電子元器件的質(zhì)量，使得能提前完成加工數(shù)量，對(duì)工作環(huán)境有如下幾點(diǎn)要求：首先是溫度要求，廠房?jī)?nèi)常年佳溫度在二十三±三℃，不可以超過(guò)極限溫度十五到三十五℃。其次是濕度要求，貼片加工車(chē)間的濕度對(duì)產(chǎn)品的質(zhì)量有很大的影響，環(huán)境濕度越大，電子元器件就容易受潮，就會(huì)影響導(dǎo)電性能，同時(shí)在焊接時(shí)不順暢，濕度太低，車(chē)間里的空氣干燥，就會(huì)產(chǎn)生靜電，所以在進(jìn)入SMT貼片加工車(chē)間時(shí)，加工人員還需穿防靜電服。一般情況下要求車(chē)間保持恒定濕度在百分之四十五到百分之七十RH左右。SMT降低成本達(dá)30%~50%。</p><div
