style="text-indent:25px">smt貼片表面安裝元器件在功能上和插裝元器件沒有差別，其不同之處在于元器件的封裝。表面安裝的封裝在焊接時要經(jīng)受耐高溫度的元器件和基板必須具有匹配的熱膨脹系數(shù)。表面安裝的焊點既是機(jī)械連接點又是電氣連接點，合理的選擇對提高PCB設(shè)計密度、可生產(chǎn)性、可測試性和可靠性都產(chǎn)生決定性的影響。這些因素在產(chǎn)品設(shè)計中必須全盤考慮。選擇合適的封裝，其優(yōu)點主要是：1有效節(jié)省PCB面積；2提供更好的電學(xué)性能；3對元器件的內(nèi)部起保護(hù)作用，免受潮濕等環(huán)境影響；4提供良好的通信聯(lián)系；幫助散熱并為傳送和測試提供方便。</p><p style="text-indent:25px">smt貼片所用設(shè)備為自動光學(xué)檢測（AOI），訂單量通常在上萬以上，訂單量小的就通過人工檢測。位置根據(jù)檢測的需要，可以配置在生產(chǎn)線合適的地方。有些在回流焊接前，有的在回流焊接后。維修：其作用是對檢測出現(xiàn)故障的PCB板進(jìn)行返修。所用工具為烙鐵、返修工作站等。配置在AOI光學(xué)檢測后。分板：其作用是對多連板PCBA進(jìn)行切分，使之分開形成單獨個體，一般采用V-cut與機(jī)器切割方式。磨板：其作用是對有毛刺的部位進(jìn)行磨砂，使其變得光滑平整。洗板：其作用是將組裝好的PCB板上面的對人體有害的焊接殘留物如助焊劑等除去。分人工清洗和清洗機(jī)清洗，位置可以不固定，可以在線，也可不在線。smt是印刷電路板，是重要的電子部件，是電子元器件的支撐體，是電子元器件電氣連接的提供者。</p><div
