Battery PL test device
Serial number   Project   Detail
1   Camera light source   HD line scan camera; Line laser
2   Size   1.Specific combination of actual layout scheme design
2.Automatic blanking is provided
3   Capacity   >4000
4   Support cell   1. Single crystal
2. 156-230mm
5   Cell state   Finished battery piece shoot the front of the battery piece
6   Shooting defect   PL can be photographed defects: black spots suction cup marks graphite boats hidden cracks etching oil spots concentric circles scratches
Other pollution and all the usual defects(★Different battery processes will lead to differences in the strength of defect imaging)
7   Process contribution   1.AI algorithm automatically detects
2.Hidden crack culling alarm to prevent batch defects
3.Break grid virtual printing alarm prevent batch defects
8   Advantage   1.Contactless loss
2.Probe free loss
3.High productivity
4.SE offset off grid virtual printing poor sintering appear white more obvious than EL
