style="text-indent:25px">SMT貼片加工對環(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，對工作環(huán)境有如下幾點(diǎn)要求：首先是溫度要求，廠房內(nèi)常年佳溫度在二十三±三℃，不可以超過極限溫度十五到三十五℃。其次是濕度要求，貼片加工車間的濕度對產(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，就會影響導(dǎo)電性能，同時(shí)在焊接時(shí)不順暢，濕度太低，車間里的空氣干燥，就會產(chǎn)生靜電，所以在進(jìn)入SMT貼片加工車間時(shí)，加工人員還需穿防靜電服。一般情況下要求車間保持恒定濕度在百分之四十五到百分之七十RH左右。</p><p style="text-indent:25px">電子產(chǎn)品采用SMT技術(shù)有什么優(yōu)點(diǎn)和好處？1. 電子產(chǎn)品可以設(shè)計(jì)的更輕薄短小，零件變得更小，電路板的體積也會變得更??；2. 設(shè)計(jì)出更**的產(chǎn)品，可以讓電子產(chǎn)品應(yīng)用到更多領(lǐng)域，比如CPU和智能手機(jī)；3. 適合大量生產(chǎn)，因?yàn)镾MT技術(shù)代替了人工插件作業(yè)，以自動(dòng)化貼片機(jī)來放置電子零件，所以更適合大量生產(chǎn)出***的產(chǎn)品，并且更穩(wěn)定。4. 降低生產(chǎn)成本，SMT整線設(shè)備基本實(shí)現(xiàn)了全自動(dòng)化，從印刷機(jī)到貼片機(jī)再到回流焊，不僅提高了產(chǎn)能，同時(shí)降低了人力成本。SMT電子產(chǎn)品追求小型化，以前使用的穿孔插件元件已無法縮小。</p><div style="width:100%;text-align: center;"><img

style="text-indent:25px">多年來，采用單調(diào)彎曲點(diǎn)測試方法是封裝的典型特征，該測試在 IPC/JEDEC-9702 《板面水平互聯(lián)的單調(diào)彎曲特性》中有敘述。該測試方法闡述了印刷電路板水平互聯(lián)在彎曲載荷下的斷裂強(qiáng)度。但是該測試方法無法確定大允許張力是多少。對于制造過程和組裝過程，特別是對于無鉛 PCA 而言，其面臨的挑戰(zhàn)之一就是無法直接測量焊點(diǎn)上的應(yīng)力。為多采用的用來描述互聯(lián)部件風(fēng)險(xiǎn)的度量標(biāo)準(zhǔn)是毗鄰該部件的印刷電路板張力，這在 IPC/JEDEC-9704 《印制線路板應(yīng)變測試指南》中有敘述。電子產(chǎn)品追求小型化，以前使用的穿孔插件元件已無法縮小。江蘇樣片SMT貼片生產(chǎn)廠家</p><p style="text-indent:25px">貼裝所用設(shè)備為貼片機(jī)，位于SMT生產(chǎn)線中絲印機(jī)的后面。江蘇樣片SMT貼片生產(chǎn)廠家</p><p style="text-indent:25px">簡述smt貼片加工中焊接材料的分類特點(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。焊錫絲的直徑種類很多，常用的有4mm、3mm、2mm、1.5mm等。江蘇樣片SMT貼片生產(chǎn)廠家</p><p
