Model 4990


The ESI Model 4990 is the most popular laser trimming system available today for thick and thin-film trimming on a variety of substrates. It incorporates a high speed galvanometer driver that significantly reduces beam positioner move times for increased throughput. Integrated pattern recognition automatically locates parts quickly and reliably for accurate placement of laser trims, and automates the trimming process. Real-time data gathering and process control are accomplished with dual computer architectures. On the front end, ESI's graphical user interface runs at high speed on a Windows™ operating system.
