Used Other Machines: ATW MS40 of 2021

EQUIPMENT DESCRIPTION 1. Stringers ATW (Wuxi Autowell) MS40A; year 2020; 2 units One of the ATW MS40a works only on one of the two sides (our technicians started to use it as a spare part resource for other stringers) 2. Stringer ATW MS40T; year 2021 Fully automatic machine, which can be used with different types of silicon solar cells, monocrystalline or polycrystalline, and solder them into a string 2.1.Cell Cell type: 156~230mm silicon cell Cell thickness: 170um to 200um Number of cell busbar: 3BB-12BB (tooling replacement is required for cells with different busbar number). Suitable for 156~230mm half-cut cells 2.2.
