LED封裝膠操作工藝指導

  LED封裝膠是(shi)指以環(huan)氧(yang)樹脂為主要(yao)成份，添加各種(zhong)功能性助劑(ji)，與合適(shi)的固化劑(ji)進行配套使(shi)用(yong)(yong)的一類環(huan)氧(yang)樹脂液體灌封或(huo)封裝材(cai)料。固化后(hou)成為高分子(zi)材(cai)料，可強化電(dian)子(zi)器件(jian)的整(zheng)體性，具有抗沖(chong)擊、抗震動(dong)、防水(shui)、防潮等等優越功能，早(zao)就應用(yong)(yong)于家用(yong)(yong)電(dian)器、電(dian)工電(dian)氣、儀器儀表等領域，雖(sui)然(ran)使(shi)用(yong)(yong)到不(bu)同的產品領域，但在操(cao)作施膠方式基本相(xiang)差不(bu)大(da)

       LED封裝膠有常(chang)態和(he)真(zhen)空兩(liang)種(zhong)灌(guan)封(feng)(feng)工(gong)(gong)藝。環氧樹脂．胺類常(chang)溫固化灌(guan)封(feng)(feng)料(liao)(liao)，一(yi)般用(yong)(yong)于(yu)低壓電(dian)器，多(duo)(duo)采用(yong)(yong)常(chang)態灌(guan)封(feng)(feng)。環氧樹脂．酸酐加熱固化灌(guan)封(feng)(feng)料(liao)(liao)，一(yi)般用(yong)(yong)于(yu)高壓電(dian)子器件灌(guan)封(feng)(feng)，多(duo)(duo)采用(yong)(yong)真(zhen)空灌(guan)封(feng)(feng)工(gong)(gong)藝。無論是(shi)常(chang)態，還是(shi)真(zhen)空灌(guan)封(feng)(feng)工(gong)(gong)藝均分(fen)為人工(gong)(gong)灌(guan)膠(jiao)與機械灌(guan)膠(jiao)，那么下面便(bian)詳細(xi)介紹一(yi)下這兩(liang)種(zhong)灌(guan)膠(jiao)方式(shi)。
