Laser Patterning
Laser Patterning
The laser patterning process is a dry process that forms the patterns of circuits and elements required for each device. Laser selectively removes various types of functional laminated films formed on a glass substrate or film substrate.
ITO film patterning on glass substrate
Line width: 25μm
ITO film patterning on film
Line width:30μm
Silver paste patterning on film
Line width: 25μm
The system has been widely used for especially electrode formation of transparent films such as ITO, silver nanowire, CNT and silver paste.
Features of Laser Patterning
- ▶The laser light source can be selected from near-infrared wavelength to ultraviolet wavelength, so it can be used in various applications.
- ▶Flexible patterning with high-speed output control of laser light.
- ▶Steady laser scan speed enables a uniform processing.
- ▶High-accuracy patterning combined digital Galvano scanner and drive stage.
- ▶Offering 3types of systems ranging from R&D use to mass-produce use.
①Compared to photo-etching
- PC data, instead of using photomask, makes it easy to change and modify patterns.
- Fewer processes achieve man-hours and cost reduction. Maintenance cost for equipment investment also can be reduced.
- Running cost and environmental impact are reduced due to it being a dry process.
②Compared to screen printing
- Capable of <50μm microscopic pattern.
- No exposure mask
③Compared to ink-jet printing
- Compatible with materials that cannot be converted into ink.
- Forming thin-film pattern of <100nm is possible.
