As an innovator in the field of high-precision environmental control, relying on its deep technical accumulation, it has launched a revolutionary milli-K level high-precision environmental control chamber solution, injecting new impetus into industry development.
Company Strength: Innovation-driven, Technologically Leading
Jice (Nanjing) Technology Co., Ltd. was established in 2024, relying on Parent Company With deep experience in the laboratory professional field, especially in HVAC and automation technology, it is committed to providing customized high-precision environmental control solutions for the fields of chip semiconductors, optics, precision manufacturing, and scientific research and development. The company has now served many global leading enterprises in semiconductors, communication equipment, and display panels, as well as national key laboratories, demonstrating its excellent technical strength in numerous scientific research and production scenarios.
The company has a strong R&D team of 20+ elites, covering product managers, structural engineers, electrical automation experts, automation R&D personnel, and product assembly experts. At the same time, the company has its own factory, which can efficiently transform R&D results into actual products, providing customers with high-quality equipment and services. In addition, the company has also established an independent and professional after-sales service team to ensure the stable operation of customer equipment and comprehensively improve customer satisfaction.
In high-precision experiments, the impact of environmental fluctuations cannot be ignored. Temperature fluctuations can lead to uneven temperature distribution in the experimental area, affecting the accuracy and repeatability of experimental results; humidity changes will interfere with the progress of biological experiments, material aging experiments, etc.; air disturbances will cause physical interference to microscopic experimental samples, changing the position or posture of macroscopic experimental devices or samples; it will also affect the accuracy of optical instruments and precision balances, introducing dust particles, harmful gases and other impurities and pollutants.
The precision environmental control system significantly suppresses air disturbance and drift disturbance. Data shows that after the precision environmental control system is turned on, the cumulative error amplitude at the 0.05Hz, 0.15Hz, and 1Hz frequency points decreases by 98.03%, 86.07%, and 85.83% respectively, the drift disturbance is significantly suppressed, the fluctuation range decreases by about 50%, and the standard deviation decreases by 45%. At the same time, temperature fluctuations have a significant impact on the parameters of ultra-fast lasers. When the ambient temperature changes by more than 0.8℃, the pulse width will exhibit a breathing phenomenon, affecting the performance of the ultra-fast laser, and the more stable the temperature, the better the laser parameters.
Influencing Factors: Multi-dimensional Challenges, Comprehensive Control
The precision environment is affected by many factors. Temperature fluctuations can cause deformation of instruments, equipment, and samples under test, affecting the fluctuation of air refraction; humidity fluctuations will affect the refractive index of air, and excessive humidity can easily cause electrical failures; carbon dioxide concentration and pressure gradient fluctuations will affect the refractive index of air; micro-vibrations will cause instruments and equipment to shake, affecting the optical path; electromagnetic interference and excessive grounding resistance will affect the normal operation of instruments and equipment.
Jice (Nanjing) Technology Co., Ltd. provides complete solutions for different environmental control needs. For ordinary environmental control needs, the temperature control accuracy is ±2℃, the humidity control accuracy is ±5~15%, the cleanliness level is from 100,000 to 100, and a constant temperature and humidity clean room is used; for precision environmental control needs, the temperature control accuracy is ±0.5~1℃, the humidity control accuracy is ±2~5%, the cleanliness level is from 10,000 to 100, and a precision constant temperature and humidity clean room is used; for high-precision environmental control needs, the temperature control accuracy is ±0.1~0.3℃, the humidity control accuracy is ±2~5%, the cleanliness level is from 1,000 to 100, and a high-precision constant temperature and humidity clean room is used; for ultra-precision environmental control needs, the temperature control accuracy is ±0.002~0.1℃, the humidity control accuracy is ±1~5%, the cleanliness level is from 100 to 10, a precision environmental control system is built in a high-precision constant temperature and humidity clean room, and airflow/wind speed/pressure difference control, CO₂ concentration adjustment, noise control, and environmental parameter closed-loop control are performed.
The company uses relative humidity to be guaranteed by the external environment, and the large environment controls the absolute moisture content in the air to remain stable, so as to achieve the stability of the humidity inside the environmental chamber. Its ultra-precision environmental control chamber has an advanced internal structure, including a zoned air supply static pressure chamber, a zoned return air duct, a milli-K level temperature measurement and acquisition module + 1/10Bpt100 matrix distribution, and a mid-low frequency absorption/resistance silencing design scheme. Self-developed high-precision temperature control technology, the outlet water temperature of the chilled water can reach ±0.002℃ with the highest accuracy.
In terms of temperature control, the design concept of large air volume and small temperature difference is adopted. By quickly circulating air filtration and removing heat, the temperature fluctuation is kept at an extremely low value, and the key area can reach ±0.002℃. Multi-level temperature control is also adopted to gradually improve the temperature accuracy. A closed protective cover is designed for the optical path part, and the surface openings can effectively reduce the temperature of the heat-generating area and control the wind speed. For local heat-generating areas, local air baths are used for temperature control to ensure that the temperature in this area is within a certain range, and the temperature change rate within 30s does not exceed 0.03℃.
After the installation of the precision environmental control system, the accuracy is significantly improved. The temperature stability is improved from ±2℃ to ±0.004℃, the humidity stability is improved from ±10% RH to ±0.8% RH, the cleanliness is improved from class 100 to class 10, the noise level is reduced from 70dB to 55dB, and the measurement error is reduced from 400 to 4.
In addition, the company also provides precision water-cooled chilled water temperature control technology, using self-developed high-precision temperature acquisition modules, stepless adjustment of chilled water valves, etc., and the outlet water temperature fluctuation can reach ±0.002℃.
