SMT制(zhi)(zhi)氮(dan)機(ji)(ji)(ji)(ji)是在SMT（表面貼裝技術）行業中(zhong)(zhong)廣泛應用(yong)(yong)的(de)(de)(de)(de)(de)一種設(she)備，主要(yao)用(yong)(yong)于(yu)(yu)產生(sheng)高純(chun)度(du)(du)氮(dan)氣(qi)(qi)(qi)，以(yi)(yi)滿(man)足SMT工藝(yi)過(guo)程中(zhong)(zhong)的(de)(de)(de)(de)(de)特殊需求。SMT制(zhi)(zhi)氮(dan)機(ji)(ji)(ji)(ji)通(tong)常采用(yong)(yong)變(bian)壓(ya)吸(xi)(xi)附原理，以(yi)(yi)碳(tan)分(fen)(fen)子(zi)篩(shai)(shai)為吸(xi)(xi)附劑，從壓(ya)縮空(kong)氣(qi)(qi)(qi)中(zhong)(zhong)提(ti)取氮(dan)氣(qi)(qi)(qi)。這(zhe)種制(zhi)(zhi)氮(dan)方式不僅，而且能(neng)(neng)保證氮(dan)氣(qi)(qi)(qi)的(de)(de)(de)(de)(de)穩定(ding)性(xing)和(he)純(chun)度(du)(du)。SMT制(zhi)(zhi)氮(dan)機(ji)(ji)(ji)(ji)的(de)(de)(de)(de)(de)氮(dan)氣(qi)(qi)(qi)純(chun)度(du)(du)一般可達99.9%以(yi)(yi)上，甚(shen)至可以(yi)(yi)達到99.999%的(de)(de)(de)(de)(de)超高純(chun)度(du)(du)，滿(man)足SMT工藝(yi)對氮(dan)氣(qi)(qi)(qi)的(de)(de)(de)(de)(de)要(yao)求。在SMT工藝(yi)中(zhong)(zhong)，氮(dan)氣(qi)(qi)(qi)主要(yao)用(yong)(yong)于(yu)(yu)抑制(zhi)(zhi)焊(han)錫的(de)(de)(de)(de)(de)氧化(hua)，提(ti)高焊(han)接潤濕性(xing)，減(jian)(jian)少焊(han)接缺陷，如(ru)錫球和(he)橋(qiao)接的(de)(de)(de)(de)(de)產生(sheng)。因此，SMT制(zhi)(zhi)氮(dan)機(ji)(ji)(ji)(ji)的(de)(de)(de)(de)(de)穩定(ding)性(xing)和(he)可靠性(xing)至關重要(yao)。它(ta)采用(yong)(yong)的(de)(de)(de)(de)(de)控制(zhi)(zhi)系統，實現自(zi)動化(hua)運行，大(da)大(da)減(jian)(jian)輕了(le)(le)操(cao)作(zuo)人員的(de)(de)(de)(de)(de)負擔，同(tong)(tong)時提(ti)高了(le)(le)生(sheng)產效率。此外，SMT制(zhi)(zhi)氮(dan)機(ji)(ji)(ji)(ji)還具(ju)有操(cao)作(zuo)簡(jian)便、維護方便的(de)(de)(de)(de)(de)特點。其設(she)計(ji)合理，內部構(gou)件氣(qi)(qi)(qi)流分(fen)(fen)布(bu)均(jun)勻，有效減(jian)(jian)輕氣(qi)(qi)(qi)流高速(su)沖擊對設(she)備的(de)(de)(de)(de)(de)影響。同(tong)(tong)時，襄城(cheng)高壓(ya)制(zhi)(zhi)氮(dan)機(ji)(ji)(ji)(ji)，特有的(de)(de)(de)(de)(de)分(fen)(fen)子(zi)篩(shai)(shai)保護措施(shi)能(neng)(neng)延(yan)長碳(tan)分(fen)(fen)子(zi)篩(shai)(shai)的(de)(de)(de)(de)(de)使(shi)用(yong)(yong)壽命，降低(di)使(shi)用(yong)(yong)成(cheng)本。總的(de)(de)(de)(de)(de)來說，SMT制(zhi)(zhi)氮(dan)機(ji)(ji)(ji)(ji)是SMT行業中(zhong)(zhong)的(de)(de)(de)(de)(de)關鍵(jian)設(she)備之一，它(ta)以(yi)(yi)其、穩定(ding)、可靠的(de)(de)(de)(de)(de)性(xing)能(neng)(neng)，為SMT工藝(yi)提(ti)供了(le)(le)的(de)(de)(de)(de)(de)氮(dan)氣(qi)(qi)(qi)保障，有效提(ti)升了(le)(le)SMT生(sheng)產的(de)(de)(de)(de)(de)效率和(he)質量。
