532nm green laser engraving keyboard, not easy to wear
In the mobile Internet era, the application scenarios of mobile phones are very extensive, but computers are still indispensable in people's office and life. People use computers to develop programs, play games, watch videos, obtain information, send and receive emails, and edit documents.
The keyboard is the golden partner of the computer. With the passage of time, for example, the keyboards of game enthusiasts, the combinations of WASD, QWER, 1234, etc. on their keyboards, or the ctrl, shift, alt, tab, win and other keys commonly used by programmers, are frequently used and cause sticking. Or the printed letters or symbols are worn out, resulting in unclear reading or even falling off. Over time, these keyboards will have to be replaced.
Using laser marking technology to mark the keys of the keyboard, the obtained marks are permanent and wear-resistant, which is of great benefit to improving the experience of consumers.
Laser marking is a process of quickly marking and obtaining marks on the surface of various materials by using high-energy density laser beams according to the preset patterns designed and typed by computer. The laser marking is fast and precise, the fineness can reach the micron level, and the marking effect is clear and three-dimensional. High-quality and fine marking on plastic materials, 532nm green laser engraving can bring a lot of surprises.
The single photon energy engraved by the 532nm green laser is high (3.49eV), which is higher than the bond energy of the C-C bond of the plastic material. When marking, it can directly break the chemical bond in the material or the surrounding medium. The whole process is mainly photochemical reaction. Small and small pulse width (about 25ns), the heat is more on the surface of the plastic material, and the heat-affected zone of the inner layer and the surrounding area is small, so the 532nm green laser engraving is also called "cold" processing. After adjusting the marking parameters, the marking will not be deformed or burnt. Therefore, it is also commonly used in the field of marking of heat-sensitive materials such as plastics and polymers.
In addition, the marking process is non-contact and material-friendly; the marking effect is long-lasting, wear-resistant, and can withstand repeated use; high beam quality (M2 < 1.2) and the easy focusing characteristics of 532nm green laser engraving, focusing The rear light spot is small, which can mark smooth and delicate lines, which is refreshing. At the same time, the 355nm ultraviolet nanosecond laser can cooperate with the production line to automatically load and unload materials, automatically feed in and out of materials, and can be processed repeatedly with very high consistency.
