style="text-indent:25px">由于SMT貼片無(wú)鉛焊接溫度比有鉛焊接高，尤其大尺寸、多層板，以及有熱容量大的元器件時(shí)，峰值溫度往往要達(dá)到260℃左右，冷卻凝固到室溫的溫差大，因此，無(wú)鉛焊點(diǎn)的應(yīng)力也比較大。再加上較多的IMC，IMC的熱膨脹系數(shù)比較大，在高溫工作或強(qiáng)機(jī)械沖擊下容易產(chǎn)生開裂。QFP、Chp元件及BGA焊點(diǎn)空洞，分布在焊接界面的空洞會(huì)影響PCBA中個(gè)元器件的連接強(qiáng)度；SOJ引腳焊點(diǎn)裂紋及BGA焊球與焊盤界面的裂紋缺陷，焊點(diǎn)裂紋和焊接界面的裂紋都會(huì)影響PCBA產(chǎn)品的長(zhǎng)期可靠性。另一類是處于焊接界面的空洞(或稱微孔)，這類空洞非常小，甚至只有通過(guò)掃描電子顯微鏡（SEM）才能發(fā)現(xiàn)?？斩吹奈恢煤头植伎赡苁窃斐呻娺B接失效的潛在原因。特別是功率元件空洞測(cè)會(huì)使元件熱阻增大，造成失效。研究表明，焊接界面的空洞（微孔）主要是由于Cu的高溶解性造成的。由于無(wú)鉛焊料的熔點(diǎn)高，而且又是高Sn焊料，Cu在無(wú)鉛焊接時(shí)的溶解速度比Sn-Pb焊接時(shí)高許多。無(wú)鉛焊料中銅的高溶解性會(huì)在銅與焊料的界面產(chǎn)生“空洞”，隨著時(shí)間的推移，這些空洞有可能會(huì)削弱焊點(diǎn)的可靠性。加工SMT貼片過(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。</p><div

style="text-indent:25px">在SMT貼片加工中，隨著PCBA電路板的集成度越來(lái)越高，集成電路的內(nèi)絕緣層越來(lái)越薄，這個(gè)怎么解釋呢？大家可以從相關(guān)芯片的制程能力新聞中可以窺探一二，比如說(shuō)5nm的制程工藝在指甲蓋大小的體積內(nèi)要塞進(jìn)上百億個(gè)晶體管，可想而知精密度的大小問(wèn)題。那么就會(huì)牽扯到互連導(dǎo)線寬度與間距的問(wèn)題，毋庸置疑間距是越來(lái)越小的。例如，CMOS器件絕緣層的典型厚度約為0.Ium，其相應(yīng)耐擊穿電壓在80～100V：VMOS器件的絕緣層更海，擊穿電壓為30V。而在電子產(chǎn)品制造及運(yùn)輸、存儲(chǔ)等過(guò)程中所產(chǎn)生的靜電電壓遠(yuǎn)遠(yuǎn)超過(guò)CMOS器件的擊穿電壓，往往會(huì)使器件產(chǎn)生硬擊穿或軟擊穿（器件局部損傷）現(xiàn)象，使其失效或嚴(yán)重影響產(chǎn)品的可靠性。杭州smt貼片電子廠</p><p
