What is ultrafast laser processing? Ultrafast laser is a pulse laser with pulse width of picosecond level and below. 1 picosecond is equal to 10⁻¹² of a second, the speed of light in air is 3 X 10⁸m/s, and it takes about 1.3 seconds for light to travel from the Earth to the Moon. During the 1-picosecond time, the distance of light motion is 0.3mm. A pulse laser is emitted in such a short time that the interaction time between ultrafast laser and materials is also short. Compared with traditional laser processing, the heat effect of ultrafast laser processing is relatively small, so ultrafast laser processing is mainly used in fine drilling, cutting, engraving surface treatment of hard and brittle materials such as sapphire, glass, diamond, semiconductor, ceramics, silicone, etc.The high-precision processing of ultrafast laser equipment needs a high-precision chiller to cool. S&A high-power & ultrafast laser chiller, with temperature control stability of up to ±0.1℃, can prov...

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...

Room temperature and flow are two factors that greatly affect the industrial chiller cooling capacity. Ultrahigh room temperature and ultralow flow will affect the chiller cooling capacity. The chiller works at room temperature above 40 ℃ for a long time will cause damage to the parts. So we need to observe these two parameters in real time.First, when the chiller is turned on, take the T-607 temperature controller as an example, press the right arrow button on the controller, and enter the status display menu. "T1" represents the temperature of the room temperature probe, when the room temperature is too high, the room temperature alarm will set off. Remember to clean up the dust to improve ambient ventilation. Continue to press the "►" button, "T2" represents the flow of the laser circuit. Press the button again, "T3" represents the flow of the optics circuit. When detected a traffic drop, the flow alarm will set off. It is time to replace the circulating water, and clean the filt...
