固化(hua)后：固化(hua)后耐焊(han)(han)(han)料溫(wen)度(du)不(bu)均(jun)(jun)勻，容易導致(zhi)焊(han)(han)(han)膏顏(yan)色不(bu)均(jun)(jun)勻，當溫(wen)度(du)過(guo)高(gao)甚至會造(zao)成局(ju)部變黃，變黑，smt電(dian)路(lu)板(ban)(ban)貼(tie)片加工，影響焊(han)(han)(han)料的美觀(guan)(guan)。當絲(si)網(wang)(wang)印(yin)刷(shua)焊(han)(han)(han)錫油墨時，由(you)于絲(si)網(wang)(wang)印(yin)刷(shua)表(biao)面(mian)(mian)不(bu)平坦，SMT電(dian)路(lu)板(ban)(ban)貼(tie)片來(lai)料加工，經過(guo)一段(duan)時間的絲(si)網(wang)(wang)印(yin)刷(shua)后，刮(gua)板(ban)(ban)表(biao)面(mian)(mian)會變得不(bu)均(jun)(jun)勻，因(yin)(yin)此在阻焊(han)(han)(han)層表(biao)面(mian)(mian)會留下刮(gua)痕。因(yin)(yin)此，操(cao)作者必須隨(sui)時注意觀(guan)(guan)察表(biao)面(mian)(mian)狀(zhuang)況，一旦(dan)發現刀(dao)痕跡，應(ying)立即擦(ca)拭刀(dao)，以(yi)確保其平滑(hua)性。為了獲得具(ju)有良(liang)好外觀(guan)(guan)質量(liang)的印(yin)刷(shua)板(ban)(ban)，遼(liao)陽電(dian)路(lu)板(ban)(ban)貼(tie)片，清潔度(du)的絲(si)網(wang)(wang)印(yin)刷(shua)室起(qi)著關鍵作用。

1、固(gu)化溫(wen)度越高以及固(gu)化時間越長，粘接強(qiang)度也越強(qiang)。

2、由于貼片(pian)膠(jiao)的(de)溫(wen)度(du)會隨著基板零件的(de)大小和(he)貼裝位置的(de)不(bu)同而變化，因此我們(men)建(jian)議(yi)找(zhao)出合適的(de)硬化條(tiao)件。紅膠(jiao)的(de)儲(chu)(chu)存：在室(shi)溫(wen)下可儲(chu)(chu)存7天，smt電路板貼片(pian)來料加工，在小于5℃時儲(chu)(chu)存大于個(ge)6月，在5～25℃可儲(chu)(chu)存大于30天。由于SMT貼片(pian)紅膠(jiao)受溫(wen)度(du)影響用本身粘(zhan)度(du)，流(liu)動性，潤濕等(deng)特性，所以(yi)SMT貼片(pian)紅膠(jiao)要有一定的(de)使用條(tiao)件和(he)規(gui)范的(de)管(guan)理(li)。

表(biao)面(mian)貼(tie)(tie)裝(zhuang)(zhuang)技(ji)術所用元(yuan)器(qi)件(jian)(jian)(jian)包(bao)(bao)括表(biao)面(mian)貼(tie)(tie)裝(zhuang)(zhuang)元(yuan)件(jian)(jian)(jian)與表(biao)面(mian)貼(tie)(tie)裝(zhuang)(zhuang)器(qi)件(jian)(jian)(jian)。表(biao)面(mian)貼(tie)(tie)裝(zhuang)(zhuang)元(yuan)件(jian)(jian)(jian)主要(yao)包(bao)(bao)括：矩(ju)形(xing)貼(tie)(tie)片(pian)(pian)(pian)元(yuan)件(jian)(jian)(jian)、圓柱(zhu)形(xing)貼(tie)(tie)片(pian)(pian)(pian)元(yuan)件(jian)(jian)(jian)、復合貼(tie)(tie)片(pian)(pian)(pian)元(yuan)件(jian)(jian)(jian)、異形(xing)等貼(tie)(tie)片(pian)(pian)(pian)元(yuan)件(jian)(jian)(jian)。表(biao)面(mian)貼(tie)(tie)裝(zhuang)(zhuang)器(qi)件(jian)(jian)(jian)主要(yao)包(bao)(bao)括：二極管(guan)、晶體管(guan)、集成(cheng)電路等貼(tie)(tie)片(pian)(pian)(pian)半導體器(qi)件(jian)(jian)(jian)。 所以進行電路設(she)計的時候，除卻對(dui)貼(tie)(tie)片(pian)(pian)(pian)元(yuan)器(qi)件(jian)(jian)(jian)提出某些(xie)與傳統電子元(yuan)器(qi)件(jian)(jian)(jian)相同的性能技(ji)術指標要(yao)求外，還需要(yao)提出其他更(geng)多(duo)、更(geng)嚴格的要(yao)求。
