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(shí)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(diǎn)既是機(jī)械連接點(diǎn)又是電氣連接點(diǎn)，合理的選擇對提高PCB設(shè)計(jì)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(jì)中必須全盤考慮。選擇合適的封裝，其優(yōu)點(diǎn)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。福建控制板SMT貼片銷售SMT貼片工序簡單，焊接較少，適合于自動(dòng)化生產(chǎn)，生產(chǎn)效率也高。</p><div
