Micro Laser Patterning Machine

Laser patterning applies to the ablation, elimination or structuring in the thickness range of up to a few microns of thin usable layers on glass in our concept. Laser Patterning machine is equipped with multi-head, direct write, step and scan laser patterning tool that has been designed for simultaneous processing on opposite sides of thin panels. Laser beams are specifically irradiated onto translucent conductive films that shape a film on glass substrates and film components, such as ITO and metallic thin films of Cr, Al and other alloys. This approach facilitates the production of system patterns at high-speed and high-precision. This laser micro patterning machine is ideal for thin-film multilayer trimming application

Transparent Conductive Oxide (TCO) thin films made of Indium Tin Oxide ( ITO) are popular for both Flat Panel Displays (FPD), Solar Cells and Touch Panels technologies. The ITO acts as a clear chain, interconnecting transistors and pixels on the back plane of column and row drivers, or on the front panel of touchscreens, providing conductivity and light transmission.Conventionally, using photolithography, this complex pattern is developed and is the most commonly used technique used by manufacturers in the industry. The ITO is patterned through a sequence of masking, projection and wet chemical etching processes before progressing to corresponding phases of the manufacture of the unit. TCO laser printing, as an alternative to wet chemical etching, is the direct writing of patterns in a single phase process. Laser manufacturing TCO requires laser content ablation, which consequently eliminates time and pollution, thus providing cost-effective and environmentally friendly bulk output.
