晶体硅太阳能电池-太阳能导电银浆-电池片丝网印刷常见问题解决方案

1.印刷速度对印刷效果的影响?

印刷速度提高,会使浆料对网孔的填充效果变差。使印刷的平整性变差,容易造成葫芦状栅线。在一定范围内,印刷速度提高,可以使栅线高度上升,宽度变小。

2.浆料黏度对印刷效果的影响?

浆料的黏度如果太小,会导致印刷的图形易扩大。产生气泡,毛边;

浆料的黏度如果太大,会导致透墨性差,会产生橘皮,小孔。

在许可范围内,浆料的黏度越小越好。

3.压力与间距的关系?

压力越大,间距越大。因为压力大时,刮刀与网版接触的地方凸出来的也越多。间距小的话,硅片承受的压力会变大,容易造成碎片。两个参数不能单独改变,否则会影响印刷品质和增大碎片率。

4.烧结过程中,各温区的作用?

室温~300℃:溶剂的挥发。

300℃~500℃,有机树脂排出,需要氧气。

400℃以上,玻璃软化。

600℃以上,玻璃与减反层反应,实现导电。

5.出现铝珠怎么办?

如果是印刷过厚,就调整参数,降低板间距,提高印刷压力;

如果是绒面过大,提醒制绒改善工艺;

如果是浆料不匹配,就改善浆料。

6.出现铝包怎么办?

如果是印刷厚度偏薄,就调整参数,提高板间距,降低印刷压力;

如果是印刷不均匀,就查看网板和刮条是否有磨损,提醒生产更换,如果都没问题,就是绒面问题,提醒制绒工艺。

7.出现翘曲片怎么办?

如果是印刷过厚,调整参数,提高板间距,降低压力;

如果是硅片太薄,更换抗弯曲浆料;

如果是刮刀没装好,提醒生产重新安装;

如果是硅片厚度不均,就是原料问题。

8.出现节点怎么办?

如果是网板或刮刀不良,提醒生产更换;

如果是参数设置不合理,调整参数,降低压力。

9.出现虚印和断栅怎么办?

如果是参数不合理,就调整参数,提高压力,降低板间距。  如果是网孔堵了,擦拭网板;

如果是印刷头在行进过程中抖动,与设备协商解决;

如果是网板或刮刀磨损或者是浆料不够,就提醒生产人员更换或者添加浆料。
