Rofin has introduced its PowerLine SL 8 IC, a laser developed specifically for the fine cutting operations required during the manufacturer of TFT flat-panel displays. The beam source has been optimised to meet strict requirements on beam quality and pulse-to-pulse stability at high frequencies. A temperature management system with independent thermal monitoring, stabilisation of all relevant optical components and heat dissipation via a cooling plate ensures long-term stability and performance, which is necessary for reliable continuous operation.
The PowerLine SL 8 IC reliably cuts ITO conductive paths with the specified line width of 35µm, and the power available from this new laser means that it is capable of achieving much higher speeds than the 400mm/s demanded by the leading screen manufacturers.
