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。PCBA生產(chǎn)工序可分為幾個大的工序，
