Leader of Digital No Mask Imaging of Advanced 3D Cover-plate

GIS Equpirment high precision exposure directly on 3D glass cover-plate, bringing customers with high-resolution, high-efficiency and high-yield products and stable cooling system to ensure that the interior of the equipment is maintained at constant temperature of 22℃ to guarantee the stability of the equipment. Successfully applies the microfabrication “negative photoresist” process manufacturing technology for integrated circuit to the production of 3D glass cover-plate.
This process manufacturing technology will improve the first yield of 3D glass cover-plate (higher than 95%) with more exquisite patterns and better color restoration. Effectively improve the disadvantages of low yield, high reworking rate, thick thread of silk-screen

Digital Imaging Technology

Use TI Pattern Generator-DMD chip to produce digital image. DMD is composed of 800,000 or 2,000,000 micromirrors. Square mesh points can be presented clearly and sharply within the scope of DMD light spots. This latest digital exposure system has become a new industry standard.

375 Nanolaser

Industrial-grade 375 nm coupled laser, Independently research-and-developed laser imaging system increases laser utilization of 375 nm coupled laser from traditional 30% to 50%

High Precision Optical Engine

DPL (Digital light processing) optical system uses UV laser light source, The output laser achieves high high uniform illumination of DMD through a special collimating lens, and finally outputs the patterns through projection lens. Projection lens is a double telecentric lens using special ultraviolet optical material with characteristics of low distortion and high transmittance.
