Principles and typical applications of laser etching technology

Principles of laser etching technology

Tanks form a very small power density. Laser microcontroller cutting, cutting, corrosion, drilling and other processes.

Laser etching technical characteristics

Processing with laser non -contact, high flexibility, high -speed, noise, noise, small -lighting area, small light spot that can be focused on the laser waves, etc., in terms of eye, slices, etching, cutting size accuracy and processing quality, especially especially It is a "cold processing" that interacts with certain materials (such as polytamide) that belongs to "optical chemical". It can obtain "cold processing" with carbon -free effects, especially interacting with certain materials (such as polyimide) The "cold processing" of "optical chemistry" can obtain "cold processing" without carbonized effects, especially the "cold processing" that interacts with certain materials (such as polyimide). "Cold processing", especially the "cold processing" that interacts with certain materials (such as polytamide), is a "cold processing" that can obtain carbon -free "cold processing", especially with certain materials (such as polyacoxyl sidamia Amine) Interaction is "optical chemistry"

Typical applications of laser etching technology.

1) Film laser etching application.

benefit:

Good reproducibility, high power, fast material removal speed, no chemical corrosion pollution. ITO coating laser etching machine is a precision device that uses laser on ITO coating etching on the surface of ITOGLASS and iTofilm. It can perform high -precision and high -speed etching of various sizes on glass, PET, ITO coating, polycrystalline membrane and other oxides, and can process a variety of specifications of electrodes. It is especially suitable for electrode etching technology of mobile phone touch screen.

2) Solar battery laser padding.

benefit:

The overall structure is reasonable, the cutting speed is fast, the accuracy is high, the function is complete, the performance indicators are stable and reliable, the failure rate is low, the non -contact processing rate is high, and the scope of application is wide.

Simple and easy to work, work continuously for 24 hours, energy saving and environmental protection.

Using graphical user interface (GUI), the human -machine interface is friendly, and the cutting trajectory can be displayed in real time. The operation is simple and intuitive.

Optional image automatic recognition processing and positioning function.

Sun battery is a device that uses photoelectric effects or optical effects to directly convert energy into electrical energy. Film solar cell production process: Base (TCO conductive glass) -gels-glass cleaning-1064 laser sculpting-secondary cleaning-fixture heating and preheating-PECVD sedimentary amorphous silicon thin film-cooling clip-635 laser carving-PVD Magnetic Splash-635 Laser Padding-Test-Aging-Laser cleaning-three-time cleaning-welding polar line-layer pressure-installation framework. Laser paddles used for thin -film solar cells have a small heat affecting area and good line quality. The useless processing method is used to avoid the stress generated in the blade processing, which can effectively improve the excellent product rate of the silicon wafer modification, and at the same time, the quality of the battery padding line is greatly improved. Optional configuration CCD image processing system to achieve precision lines of special specifications of battery films.
