As we all know, ultraviolet laser marks and CO2 laser marks are both mainstream laser technologies. However, in the rapid development of the laser industry, with the advent of fiber laser, the market of CO2 laser in recent years is constantly being eaten. So can ultraviolet laser marking completely replaced the CO2 laser marking becomes a future trend? Let Hibo laser analyze it for you please.
The advantage of CO2 laser marking:
In the 1980s, because of the maturity of CO2 laser technology, it became the mainstream of laser applications. CO2 laser marking became one of the commonly used laser marking forms of laser marking due to its high efficiency and beam quality. CO2 laser is a gas laser. It uses the interaction of laser energy and material to leave permanent traces on the surface of objects. It is a revolutionary alternative to traditional technologies such as inkjet, silk printing, and knife carvings. This technology can be carved with beautiful design, trademarks, date or text on the surface of the product.
Advantages of UV laser marking:
Ultraviolet laser is a laser with a wavelength of 355nm. Due to its short wavelength and narrow pulse characteristics, it can produce very small light spots and maintain a minimum heat -impact area, which allows it to process the mechanical deformation of the material to maximize the maximum extent. It can not only provide extremely fine processing effects, but also maintain a good positioning accuracy of the ultraviolet laser.
Comparison of the two:
In applications with high accuracy requirements, such as glass, chips, and various PCB boards, ultraviolet laser is obviously better than CO2 laser. Especially in the application of various PCB materials, ultraviolet laser is considered a good choice. From the perspective of market performance, ultraviolet laser seems to suppress CO2 laser. A few years ago, the shipping volume of solid ultraviolet laser in the country was only about 3,000 units, but by 2017, the shipments of ultraviolet lasers have increased to 10,000 units, and in the future, it has stabilized with a very good growth rate. This proves that ultraviolet laser is becoming more and more popular in the market, and it also shows that people's demand for fine processing has increased.
However, this is not to say that CO2 laser is useless. At least now, the price of CO2 laser with the same power is much cheaper than ultraviolet laser, and the cost has a great advantage. In some areas, CO2 laser can do things that other laser cannot do. For example, extremely ultraviolet light is generated. In the past few decades, the light carvings in semiconductor manufacturing have been achieved through deep ultraviolet light of more than 100 nanometers. With the development of Moore's law, the semiconductor chip needs to be scheduled The increase in circuits is growing, and the requirements for fineness are becoming more and more stringent, which requires extremely ultraviolet light of about 10 nanometer wavelengths to complete the lithography. In addition, there are still many applications in the market that other types of laser cannot be competent, and only CO2 laser can be used. In some non -metallic materials and polymer materials processing applications, especially plastic applications, CO2 laser is still a very suitable choice.
Although UV laser technology is constantly popular, traditional CO2 laser technology also has its strengths, and it is constantly improving. Therefore, it is difficult for ultraviolet laser marks to completely replace CO2 laser marks, but ultraviolet laser marks are becoming more and more popular, but it is also an indisputable fact. At present, ultraviolet laser marks will only be favored by users and markets due to their fine, accurate processing and low processing and maintenance costs. As UV laser has become more popular in the past three years, the application of ultraviolet laser marks has become a trend.
