style="text-indent:25px">SMT貼片加工注意事項(xiàng)：SMT屬于表面組裝的一項(xiàng)技術(shù)，現(xiàn)階段電子組裝行業(yè)比較流行的技術(shù)，SMT貼片加工主要指把元件通過(guò)貼處設(shè)備貼到印有膠或錫膏的PCB上，然后過(guò)焊接爐。SMT貼片加工以組裝密度高、電子產(chǎn)品體積小、高頻特性好等優(yōu)點(diǎn)得到廠家認(rèn)可，因?yàn)镾MT貼片機(jī)的工作效率和穩(wěn)定的性能為我們的生產(chǎn)帶來(lái)了極大的優(yōu)勢(shì)，有了SMT貼片機(jī)，就能提高生產(chǎn)效率和能提供高質(zhì)量的產(chǎn)品給顧客。SMT貼片機(jī)相當(dāng)于一個(gè)貼片機(jī)器人，是比較精密的自動(dòng)化生產(chǎn)設(shè)備，貼片阻容元件可以先在一個(gè)焊點(diǎn)上點(diǎn)錫，再放上元件的一頭，用鑷子夾著元件，焊上一頭后看下是否放正了，若已經(jīng)放正即可焊上另一頭。</p><p style="text-indent:25px">smt貼片：印刷：其作用是將焊膏或貼片膠漏印到PCB的焊盤上，為元器件的焊接做準(zhǔn)備。所用設(shè)備為印刷機(jī)（錫膏印刷機(jī)），位于SMT生產(chǎn)線的前端。點(diǎn)膠：因現(xiàn)在所用的電路板大多是雙面貼片，為防止二次回爐時(shí)投入面的元件因錫膏再次熔化而脫落，故在投入面加裝點(diǎn)膠機(jī)，它是將膠水滴到PCB的固定位置上，其主要作用是將元器件固定到PCB板上。所用設(shè)備為點(diǎn)膠機(jī)，位于SMT生產(chǎn)線的前端或檢測(cè)設(shè)備的后面。有時(shí)由于客戶要求產(chǎn)出面也需要點(diǎn)膠，而現(xiàn)在很多小工廠都不用點(diǎn)膠機(jī)，若投入面元件較大時(shí)用人工點(diǎn)膠。SMT易于實(shí)現(xiàn)自動(dòng)化，提高生產(chǎn)效率。</p><div

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
