style="text-indent:25px">smt貼片加工采用的是片狀元器件，具有可靠性高、體積小、重量輕、抗振動(dòng)能力強(qiáng)、自動(dòng)化生產(chǎn)、安裝可靠性高、不良焊點(diǎn)率一般低于百萬(wàn)分之十，它比通孔插元件波峰焊接技術(shù)低一個(gè)數(shù)量級(jí)，能夠保證電子產(chǎn)品或元器件焊點(diǎn)低，目前，近90%的電子產(chǎn)品采用SMT工藝。高頻特性好，性能可靠：由于片式元器件貼裝牢固，器件通常是無(wú)引線或短引線，這減少了寄生電感和寄生電容的影響，提高了電路的高頻特性，減少了電磁和射頻干擾。采用SMC和SMD設(shè)計(jì)的電路大頻率可達(dá)3 GHz，而片式元件*為500 MHz，可縮短傳輸延遲時(shí)間。可用于時(shí)鐘頻率為以上16MHz以上的電路。如果采用MCM技術(shù)，計(jì)算機(jī)工作站的**時(shí)鐘頻率可達(dá)100
