style="text-indent:25px">電子產(chǎn)品的加工完成，它們的順序應該是這樣的PCB→SMT→PCBA，PCB的生產(chǎn)是非常復雜的，SMT則相對簡單，PCBA講究的是一站式服務。PCBA生產(chǎn)工序可分為幾個大的工序， SMT貼片加工→DIP插件加工→PCBA測試→成品組裝。一、SMT貼片加工環(huán)節(jié)。SMT貼片加工的工序為：錫膏攪拌→錫膏印刷→SPI→貼裝→回流焊接→AOI→返修。1、錫膏攪拌。將錫膏從冰箱拿出來解凍之后，使用手工或者機器進行攪拌，以適合印刷及焊接。2、錫膏印刷將錫膏放置在鋼網(wǎng)上，通過刮刀將錫膏漏印到PCB焊盤上。</p><p style="text-indent:25px">小尺寸的表貼電容焊接時一定要小心，特別是電源濾波電容（103或104），數(shù)量多，很容易造成電源與地短路。當然，有時運氣不好，會遇到電容本身是短路的，因此好的辦法是焊接前先將電容檢測一遍。電腦上打開PCB設圖，把短路的網(wǎng)絡點亮，看看什么地方離得近，容易連到一塊。特別要注意IC內(nèi)部的短路。如果是人工焊接，要養(yǎng)成好的習慣：1、焊接前要目視檢查一遍PCB板，并用萬用表檢查關(guān)鍵電路（特別是電源與地）是否短路；2、每次焊接完一個芯片就用萬用表測一下電源和地是否短路；PCBA貼片流程比較復雜，任何一個環(huán)節(jié)出了問題都將引起焊接品質(zhì)問題。</p><div
