設備名稱 Equipment Name

全自動卷紙印刷機  Automatic Screen Printing Equipment

設備型號 Equipment Model

SC-PT04LA

設備用途 Equipment Application

把鋁漿、銀漿通過壓力印刷至電池片表面，經(jīng)過烘干燒結(jié)后成為太陽能電池正負極。

Al & Ag paste are printed on the surface of the wafer by screen printing technology,which becomes the positive & negative electrodes after drying and firing.

工藝流程  Process Flow

上料→背電極印刷→烘干→背電場印刷→烘干→正面印刷→烘干→正面二次印刷→烘干燒結(jié)→測試分選

Loading→Rear busbar printing→Drying→BSF printing→Front busbar printing→Drying→Front double printing→Drying &firing→Testing &Sorting
