設備名稱(chēng) Equipment Name

全自動(dòng)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(guò)壓力印刷至電池片表面，經(jīng)過(guò)烘干燒結后成為太陽(yáng)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(chǎng)印刷→烘干→正面印刷→烘干→正面二次印刷→烘干燒結→測試分選

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