Combining 365, 385, and 405 nm wavelength LED emissions, Ledia 3 Wavelength Series provides accurate, high-speed exposure of demanding solder masks, with optimized solder dam edge quality and no undercut. Systems also deliver ultrafine 15 µm lines and spaces with well-defined edges when processing inner- and outer-layer resists. With built-in real-time positioning system and proprietary alignment algorithms, series automatically registers each board to within a few microns.
