Introduction to the three characteristics of laser etching machines

Laser etching machines are mainly suitable for high-speed stripping, material removal and structure of flexible films such as PET and conductive materials based on Glass, so as to achieve the purpose of etching, marking and circuit structure of material surface. It is commonly used in touch screen, photovoltaic solar energy, new energy, luminous glass and other industries, and is commonly used in touch screen ITO laser etching machine, TCO laser etching machine, ultra-large laser etching machine, perovskite battery laser etching machine and other equipment. The classification of laser etching machines is generally divided according to functions, technical characteristics and materials.

Functional division

refers to the division of laser etching machines according to their functional uses. The surface grooves of stripping substrates or metals such as gold and silver, polymer materials or flexible materials are usually named laser groove machines; in the solar photovoltaic industry, the application of solar cell lines is usually named laser lines; in the field of touch screens, conductive silver paste or ITO materials need to split materials to form lines. Chemical etching was used in the early days, and laser direct forming was later used. This naming convention is called laser etching machine or laser etching machine. The touch screen industry is the base camp of laser etching equipment. With the development of technology and applications, the initial starting point of development has gradually spread to other fields. According to the functional division, it is usually divided into multi-head laser etching machine, ultra-large laser etching machine, laser etching machine, etc.

Material property division

It is worth dividing the uses of materials that can be processed by laser etching machines. For example, the ITO material peeled off the surface of PET or glass is usually called ITO laser etcher or ITO laser etcher; the silver paste material is called conductive silver award laser etcher; it is also divided into special industries such as perovskite cell laser etcher, TCO laser etcher, FTO laser etcher according to the material characteristics. Of course, more cases are to name the laser etcher in combination with materials, functions and technical characteristics.

Technical characteristics division

In fact, this is also the main introduction point of this article. The types of laser etching machines are mainly classified according to the characteristics of the laser. At present, the definition of laser etching machines on the market mainly refers to nanosecond laser etcher, ultrafast picosecond laser etcher and femtosecond laser etcher.

The application of nanosecond laser etcher in the industrial field is divided into nanosecond infrared fiber laser etcher, nanosecond green laser etcher and nanosecond ultraviolet laser etcher according to the wavelength characteristics. Corresponding to different types, such as nanosecond infrared is mainly aimed at materials with lower requirements in the touch screen industry such as ITO and silver paste, and the equipment cost is low and stable; nanosecond green laser etcher is mainly aimed at multi-layer materials such as FTO in the photovoltaic field; nanosecond ultraviolet laser etcher is mainly aimed at metal thin film materials in the sensor field such as copper film and ceramic base film. Ultrafast laser etcher is mainly aimed at materials with high line width accuracy requirements, sensitive thermal effects or multi-layer material processing. For example, femtosecond laser etcher is often used for etching materials with line width requirements less than 10 microns, such as ITO, silver paste, gold and other materials, and can also be used for etching materials such as FTO, titanium oxide, zirconium oxide, and carbon powder.

In fact, laser etching machines will be further divided according to the characteristics of frequency, pulse width, pulse energy, etc., which are usually reflected in the product model of the laser etching machine. For example, Laisai Optoelectronics' adjustable pulse width nanosecond fiber laser etching machine is named ET650MIR. The types of laser etching machines corresponding to different needs are very different, so guests often suspect that some price differences exceed 1 million, indicating that the wavelength and pulse width have large differences. Generally speaking, the higher the power, the more expensive the price, the shorter the wavelength, the more expensive the price, and the narrower the pulse width, the more expensive the price. Therefore, guests also need to provide accurate demand information, recommend the type and effect of the laser etching machine according to their needs, and it is best to choose under the conditions of test samples.

Of course, the type classification of laser etching machines, the name is not the point, it is just a code. The key is to judge the appropriate equipment requirements according to the processing materials and processing needs. It is the so-called knowing yourself and knowing the enemy. Knowing more about laser etching machines will help guests choose the accuracy of equipment and avoid wasting time and money. Laisai Optoelectronics' employees are convenient and have accumulated rich experience in the industry. They can help guests provide accurate information and provide free proofing opportunities.
