Turntable Laser Machine with 2 Lines

The ULTAGO NX is a powerful laser processing workstation designed for high-precision applications in the photovoltaic and electronic industry. It achieves throughput of 6,000 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 on up to two lines to reach optimum productivity.
