全自动卷纸印刷机

设备名称 Equipment Name

全自动卷纸印刷机  Automatic Screen Printing Equipment

设备型号 Equipment Model

SC-PT04LA


设备用途 Equipment Application

把铝浆、银浆通过压力印刷至电池片表面,经过烘干烧结后成为太阳能电池正负极。

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.
