What Are The Applications Of UV Lasers?

Solid-state UV Lasers are divided into xenon lamp-pumped UV lasers, krypton lamp-pumped UV lasers and new laser diode-pumped all-solid-state lasers according to the pumping method. The photoelectric conversion efficiency of solid-state UV lasers is generally low, while LD all-solid-state UV lasers have the characteristics of high efficiency, high repetition frequency, reliable performance, small size, good beam quality and stable power.

UV lasers have unique properties known as "cold" processing. Using lasers with shorter wavelengths and pulse widths and lower M2 (beam quality) creates a more focused spot while maintaining a minimal heat affected zone ( HAZ), in marking applications, can keep the object as it is to the greatest extent and reduce damage during processing. Applications such as glass marking, ceramic engraving, glass drilling, and flexible circuit board cutting are very popular among processing companies.

Ultraviolet laser is a kind of light invisible to the naked eye. It has a small spot (0.07mm), narrow pulse width, fast speed and high peak output. It uses high-energy laser to locally illuminate the workpiece to vaporize the surface material or change its color. Photochemical reaction, leaving a permanent mark. High power, high pulse repetition frequency (PRF), pulse shaping and pulse splitting can all contribute to increased productivity in micromachining.

UV laser market development
In daily life, we come into contact with a variety of trademarks and signs, either metallic or non-metallic, some with words and some with patterns, etc., such as the Midea logo, the Apple logo on mobile phones, keyboard buttons, mobile phone buttons, cup graphics and text , production date of cans, etc. Many of these marks are currently achieved through UV laser marking. The reason is very simple. UV laser marking is fast and requires no consumables. Through optical principles, permanent marks can be printed on the surface of various materials, which is very helpful for anti-counterfeiting.

With the rapid development of science and technology and the arrival of the 5G era, especially the rapid development of the 3C industry, product updates are fast, and the requirements for equipment manufacturing are getting higher and higher. The speed is getting faster, the weight is getting lighter, and the price is affordable. In the processing field It is becoming more and more extensive and complex at the same time, causing the manufacturing industry of parts and components to develop towards miniaturization and precision.

Application areas of UV lasers
UV lasers have advantages that other lasers do not have. They can limit thermal stress, reduce damage to the workpiece during processing, and maintain the integrity of the workpiece. Currently, UV lasers are used in enterprise processing fields, mainly in four fields: glass technology, ceramic technology, plastic technology, and cutting technology.
1. Glass technology: Glass marking can be used in: glass bottle packaging in various industries such as wine bottles, seasoning bottles, beverage bottles, etc. It can also be used in the manufacturing of glass craft gifts, crystal marking, etc.
2. Laser cutting: UV laser equipment can be used in many fields of flexible board production, including FPC appearance cutting, contour cutting, drilling, covering film window opening, soft-hard board uncovering and trimming, mobile phone cases Cutting, PCB profile cutting, etc.
3. Plastic marking: The application scope includes most general plastics and some engineering plastics. It can also be used for plastic alloys such as PC/ABS and other materials. The writing of laser marking is clear and bright, and can mark black and white writing.
4. Ceramic engraving: The application range includes tableware ceramics, vases ceramics, building supplies, ceramic bathroom ware, tea set ceramics, etc. UV laser ceramic marking has a high peak value and small thermal effect. It has natural advantages for similar ceramic fragile products, such as etching, Engraving and cutting are not easy to damage the device, and the craftsmanship is precise, reducing waste of resources.

UV laser used in glass marking
Through the etching process, the ultraviolet laser can be better absorbed by the material when marking the glass, and is less destructive to the original glass. It uses high-energy-density laser to locally irradiate the glass to vaporize the surface material through a photochemical reaction. A marking method that leaves a permanent mark. The size of the graphics and text produced by laser marking can range from millimeters to microns, which is of special significance to the anti-counterfeiting of products.

UV laser used in flexible circuit boards
A UV laser is a laser that produces an ultraviolet beam. Currently, the main types used for laser micromachining include excimer lasers and all-solid-state lasers. Due to its short wavelength, ultraviolet laser can be absorbed by most materials and has advantages in laser material processing. As the research on ultraviolet lasers continues to deepen, the application fields of ultraviolet lasers continue to expand, and are currently used in many fields such as food, medical packaging, electronics, and semiconductors.

In the modern FPC processing process, the 355nm ultraviolet laser is a commonly used and very important advanced equipment. There are many applications, such as marking of micro-scale QR codes, drilling within 50μm, ultra-precision cutting of component patches, and removal of enameled coatings on precision coils. Because of the inherent advantages of the "cold processing" mode, various new applications of ultraviolet lasers are emerging one after another.

Application of UV laser in various PCB materials
UV lasers are the best choice for various PCB material applications in many industrial fields, from the production of the most basic circuit boards and circuit wiring to the production of pocket-sized embedded chips and other advanced processes. The difference in this material makes UV lasers the best choice for various PCB material applications in many industrial fields, from the production of the most basic circuit boards and circuit wiring to the production of pocket-sized embedded chips and other advanced processes.
