2025-03-18
By integrating ultra-precise temperature control, cleanliness management, and intelligent operation and maintenance, Jike is redefining the reliability boundaries of electronic component testing, providing an indispensable environmental foundation for the global electronics industry to move towards nano-level processes.
In the testing and production of precision electronic components, the resistance value of a micrometer-level chip may drift due to a 0.1℃ temperature change. This extreme sensitivity to the environment makesconstant temperature and humiditycontrol a core technological barrier in the electronics manufacturing industry.
Nanjing Expansion Technology's subsidiary，Jice (Nanjing) Technology Co., Ltd.'s precision environmental control cabinet,with a temperature control accuracy of ±0.002℃and Class 10cleanliness,provides a nearly "zero-interference" stable environment for high-precision electronic component testing, becoming a key tool for the industry to break through yield bottlenecks.Currently, we possess the ability to customize for all scenarios, meeting users' different environmental parameters and usage needs, such as temperature and humidity stability, cleanliness, anti-vibration, anti-magnetic, sound insulation, and other personalized needs. We have already served many global leading enterprises and national key laboratories in semiconductors, communication equipment, and display panels, and have been applied in numerous scientific research and production scenarios.
Ultra-Precision Temperature Control: From Nanometer-Level Error to Micrometer-Level Reliability
Electronic component testing has extremely demanding temperature requirements. For example, in thermal cycling tests of semiconductor wafers, if the temperature fluctuation exceeds ±0.01℃, it may lead to stress cracks caused by differences in the coefficient of thermal expansion of the material.
Jice's precision environmental control cabinet uses a closed-loop airflow circulation system. The EC fan drives the airflow along a precisely calculated path to evenly cover the inside of the equipment, controlling the temperature fluctuation in key areas to ±2mK (static)，humidity stability reaches±0.5%RH, greatly reducing the interference of environmental factors on the test results.
Cleanliness Control: Dual Protection from Dust Defense to Data Reliability
Particulate contamination in the air is an "invisible killer" for precision electronic testing. A dust particle with a diameter of 0.3μm can cause a short circuit in an integrated circuit or failure of an optical sensor. Jice equipment usesmulti-layer high-efficiency particle filters and dynamic airflow management，raising the cleanliness of the work area toISO Class 3 standard and above(number of particles ≥0.1μm per cubic meter ≤1,000), far exceeding the ISO Class 5 standard of traditional laboratories.
Data Traceability and Quiet Operation: Transformation from Laboratory Compliance to Production Efficiency
In order to meet the requirements of international standards such as ISO 17025, complete records and real-time analysis of environmental data are crucial. Jice's precision environmental control cabinet is equipped with aintelligent monitoring systemthat can automatically generate time-stamped curve reports and supports one-click export. At the same time, the equipment usesEC fansandhigh-efficiency sound insulation materials，controlling the operating noise to <45dB, providing operators with a good working environment.
Customization and Safety Protection: Full Chain Coverage from Flexible Adaptation to Risk Prevention
In response to the space limitations of electronic testing laboratories, Jice equipment usesa detachable aluminum alloy frame structure，supporting on-site assembly. The appearance color of the cabinet can be customized according to customer needs to meet the integrated needs of the company's brand image. In terms of safety protection, the equipment has automatic protection procedures and operates worry-free around the clock.
Industry Value: Technological Empowerment from Laboratory to Production Line
In high-end electronic fields such as 5G communication and autonomous driving chips, Jice's precision environmental control cabinet is not only an environmental control device but also a "catalyst" for technological innovation. Its ±0.002℃ constant temperature and humidity performance provides the ultimate solution for scenarios such as high-temperature aging tests of gallium nitride power devices and coupling precision calibration of silicon photonic chips. According to industry estimates, every 1% improvement in the stability of the testing environment can drive an increase in the annual efficiency of electronics manufacturing enterprises by about 2.3%.
By integratingultra-precision temperature control、cleanliness managementandintelligent maintenance，Jice is redefining the reliability boundaries of electronic component testing, providing an indispensable environmental foundation for the global electronics industry to move towards nanometer-level processes.
