The annual SNEC-2019 Shanghai Photovoltaic Exhibition will kick off on June 4-6. XN Automation sincerely invite you to visit the company booth. During the exhibition,XN will exhibit the CHn40 high-speed multi-busbar soldering machine, this equipment integrates laser cutting and string soldering function, and the half cell soldeiring capacity of MBB is 3600 pieces/hour. 。

　　The MBB half cell soldering process will be demonstrated on site. In order to make the power of MBB modules more efficient, XN automation has devoted themselves to research. In March 2017, XN automation launched this technology, which allows modules of the same area to be placed in more cells to improve module efficiency. Patent number ZL201710112967.2. The difficulty lies in the treatment of the round ribbons in the overlapping areas of the cells to prevent cracks and defects. 。

　　What is MBB half cell gapless soldering technology??

　That means,the negative distance string soldering is adopted between the half-cut cells, and the overlap between the cells is 0.5mm. The process is completely the same as the conventional string soldering method.

　　How to prevent cracks in the overlapping area??

　　　　XN will give the answer at the SNEC-2019 Shanghai Photovoltaic Exhibition.。
