Ink-printed keyboard keys are easy to fade. But the laser-marked keyboard keys can be marked permanently. A laser marking machine and S&A UV laser chiller can permanently mark the keyboard's exquisite graphic logo.

Laser marking is very common in industrial processing. It has high quality, high efficiency, no pollution and low cost, and has been widely used in many walks of life. Common laser marking equipment includes fiber laser marking machines, CO2 laser marking, semiconductor laser marking and UV laser marking, etc. The corresponding chiller cooling system also includes fiber laser marking machine chiller, CO2 laser marking machine chiller, semiconductor laser marking machine chiller and UV laser marking machine chiller, etc. S&A chiller manufacturer commits to the design, production and sale of industrial water chillers. With 20 years of rich experience, S&A chiller's laser marking chiller system is mature. CWUL and RMUP series laser chillers can be used in cooling UV laser marking machines, CWFL series laser chillers can be used in cooling fiber laser marking machines, and CW series laser chillers can be used in many laser marking fields. With temperature control accuracy ±0.1℃~...

Chip is the core technological product in the information era. It was born of a grain of sand. The semiconductor material used in the chip is monocrystalline silicon and the core component of sand is silicon dioxide. Going through the silicon smelting, purification, high temperature shaping and rotary stretching, sand becomes the monocrystalline silicon rod, and after cutting, grinding, slicing, chamfering and polishing, silicon wafer is finally made. Silicon wafer is the basic material for semiconductor chip manufacture. To meet the requirements of quality control and process improvement and facilitate the management and tracking of wafers in subsequent manufacturing testing and packaging processes, specific marks such as clear characters or QR codes can be engraved on the surface of the wafer or crystal particle. Laser marking uses high-energy beam to irradiate wafer in a non-contact way. While executing the engraving instruction quickly, the laser equipment also needs to be coole...
