The next generation InnoLas Solutions Turntable Machine

The ILS-TTnx is a powerful laser processing workstation designed for high-precision applications in the photovoltaic industry. It achieves throughput of 6000 wafers per hour for solar cells and is used in high-volume production environments. Different from linear table machines, in the turntable machine loading, unloading, alignment, as well as laser processing are carried out in parallel in order to reach optimum productivity.
