SMT生產工(gong)(gong)(gong)藝一般包括(kuo)焊膏印刷、貼片、回流焊、檢測等四個環節。SMT生產工(gong)(gong)(gong)藝按元器件的(de)裝貼方式(shi)可(ke)以分(fen)為(wei)純SMT裝聯工(gong)(gong)(gong)藝和(he)(he)(he)混合裝聯工(gong)(gong)(gong)藝；按線路(lu)板元件分(fen)布可(ke)以分(fen)為(wei)單面和(he)(he)(he)雙(shuang)面工(gong)(gong)(gong)藝；SMT也比THT的(de)零件要小。在(zai)smt加工(gong)(gong)(gong)焊接(jie)時，不(bu)能夠讓您的(de)頭(tou)發(fa)和(he)(he)(he)電線絞在(zai)一起，沈陽(yang)smt加工(gong)(gong)(gong)組裝，特別是長發(fa)的(de)女士，更(geng)應該注意(yi)這一點，進行smt加工(gong)(gong)(gong)焊接(jie)操作的(de)時候必須戴上防靜電帽子并且將(jiang)長的(de)頭(tou)發(fa)挽起來。

SMT貼片機單軌(gui)傳輸系(xi)統的(de)機械規范。這些系(xi)統能彼此相鄰組裝而(er)不用接口(kou)硬件，假設PCB所示從左到(dao)右(you)移(yi)(yi)動(dong)(dong)，沈陽smt加工廠(chang)家，同樣的(de)標準也用于板從右(you)向左移(yi)(yi)動(dong)(dong)。設備制造商要(yao)清晰說明板的(de)移(yi)(yi)動(dong)(dong)方向。貼片加工中(zhong)一旦(dan)出現元(yuan)(yuan)器(qi)件移(yi)(yi)位(wei)，就(jiu)會影響電路板的(de)使(shi)用性能，因(yin)此在(zai)加工過程中(zhong)就(jiu)需(xu)要(yao)了(le)解元(yuan)(yuan)器(qi)件移(yi)(yi)位(wei)的(de)原(yuan)因(yin)，并(bing)針對性進行解決(jue)。元(yuan)(yuan)器(qi)件在(zai)印刷(shua)、貼片后的(de)搬運(yun)過程中(zhong)由于振動(dong)(dong)或是不正確(que)的(de)搬運(yun)方式引(yin)起了(le)元(yuan)(yuan)器(qi)件移(yi)(yi)位(wei)。

維修(xiu)時(shi)，不能僅僅憑仗(zhang)電(dian)(dian)(dian)(dian)感(gan)量來交換(huan)貼片(pian)(pian)電(dian)(dian)(dian)(dian)感(gan)。還要曉得貼片(pian)(pian)電(dian)(dian)(dian)(dian)感(gan)的任務(wu)頻段，才干保證任務(wu)功能。貼片(pian)(pian)電(dian)(dian)(dian)(dian)感(gan)的外形(xing)、尺寸根本類似，沈(shen)陽smt加工(gong)，外形(xing)上(shang)也沒(mei)有(you)分明標志。在焊(han)接前(qian)，需要了解清楚元器(qi)件(jian)是否有(you)特別要求，如焊(han)接溫度條件(jian)，裝配方式等。有(you)些元器(qi)件(jian)不能用浸錫方法，只能用電(dian)(dian)(dian)(dian)烙鐵焊(han)接，例(li)如片(pian)(pian)狀電(dian)(dian)(dian)(dian)位(wei)器(qi)和鋁電(dian)(dian)(dian)(dian)解電(dian)(dian)(dian)(dian)容，所以就(jiu)需要根據情(qing)況選擇(ze)正(zheng)確的焊(han)接方式。
