style="text-indent:25px">在SMT貼片加工中，隨著PCBA電路板的集成度越來越高，集成電路的內(nèi)絕緣層越來越薄，這個(gè)該怎么解釋呢？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題。那么就會(huì)牽扯到互連導(dǎo)線寬度與間距的問題，毋庸置疑間距是越來越小的。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)等過程中所產(chǎn)生的靜電電壓遠(yuǎn)遠(yuǎn)超過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。</p><p style="text-indent:25px">加工SMT貼片小批量貴是因?yàn)闆]有太多數(shù)量來分?jǐn)傁鄳?yīng)的費(fèi)用。對(duì)于PCBA加工廠來說：“客戶做1片，跟做10000片所需要的工序流程是沒有一丁點(diǎn)差別的”比如元器件檢測(cè)、存樣入系統(tǒng)、錫膏回溫?cái)嚢?、PCB烘烤、貼片編程、SPI檢測(cè)、AOI檢測(cè)、首件檢測(cè)、老化測(cè)試、組裝包裝出貨等等工序。量不大、工序一樣沒少。較大的成本就在于頻繁的轉(zhuǎn)線、換料，時(shí)間成本和人工成本難以縮減。比較簡(jiǎn)單的就是機(jī)器剛跑起來就要停下來，真的非常影響生產(chǎn)效率。所以如果不是專業(yè)配置打樣線的PCB加工廠。一般也不會(huì)接小批量SMT貼片加工的訂單。SMT貼片機(jī)主要應(yīng)用于LED燈、電子產(chǎn)品、顯示屏領(lǐng)域,具有智能化的貼片操作,更精細(xì)的識(shí)別定位等特點(diǎn)。</p><div
