Hitachi High-Technologies GLOBAL

By using laser, these machines can form a circuit directly into transparent conductive films, extraction electrodes, etc. in functional films that are used on touch screen panels.
We offer a reduction in manufacturing cost and flexibility through a web process.

Special Features

High process adaptability by matching with multiple wavelengths

Selectable wavelength from Ultraviolet light 355 nm or visible light 532 nm or near-infrared light 1064 nm
Focusing on development applications, wavelength selection can be tailored according to work absorption

Homogeneous processing by high-speed control of the laser pulse

Stabilization of the pulse energy and pulse interval using constant velocity control
Fast emission through its own fast pulse control

Reduction of thermal effect due to the short pulse width

Emission of pulse with a width of 10 nsec is possible through a compact YVO4 laser. Thermal effect is reduced, and damage to the substrate is controlled

High precision patterning in 200mm x 200mm area

High precision positioning by digital encoder type galvanometer scanner
Optical aberrations due to three-dimensional control is eliminated, and performs well in both large scan areas and small spots
