JetStep G45 System

High Resolution Imaging; a step-and-repeat lithography panel printer

The JetStep® G45 System addresses the demanding requirements of the mobile display industry. Based on established stepper technology, the G45 System combines optimized performance capabilities with superior cost-of-ownership in a Gen 4.5 configuration. When combined with the system’s high speed frictionless motion, throughput is improved by as much as 30% over competing technologies. The System also features a small footprint and low-cost reticles for an affordable manufacturing process.
