Every advance in semiconductor process nodes, every breakthrough in optical‑component precision, and every reproducible life‑science experiment—all these technological leaps rest on a shared prerequisite: environmental control. As manufacturing precision enters the nanometer—and even sub‑nanometer—regime, even the slightest fluctuations in environmental parameters can jeopardize the stability of the entire process flow. Jice (Nanjing) Technology Co., Ltd. The independently developed UPECS high-precision environmental control system was specifically designed to meet this challenge.

From single-point control to system-wide coordination

Traditional environmental control systems typically assign temperature, humidity, cleanliness, air pressure, and other parameters to separate, standalone devices, with little coordination among the subsystems. This approach not only consumes space and increases energy consumption but also makes it difficult to achieve consistent performance across the entire environment. UPECS adopts a fundamentally different design philosophy: it integrates the equipment’s main cabinet, intelligent control system, airflow circulation system, clean‑air filtration system, cooling (and heating) system, lighting system, and localized air‑bath modules (ABMs) into a deeply interconnected, unified whole. In this architecture, multiple parameters—including temperature, humidity, cleanliness, air pressure, micro‑vibrations, and electromagnetic shielding—operate in concert under a single, cohesive control framework.

The direct benefits of this system-level integration are uniformity and stability across the entire space. UPECS can achieve up to ISO Class 1 cleanliness, maintaining temperature stability within the effective volume at no more than ±0.002°C (±2 mK), with humidity control accuracy reaching ±0.1% RH, while keeping operational noise below 45 dB. These performance metrics represent engineering‑grade delivery standards under continuous operating conditions, rather than peak values attained under ideal laboratory conditions.

Modular Architecture: Breaking the Impasse of Standardization

The field of precision environmental control has long been confronted with a paradox: while the environmental requirements of each application scenario vary widely, conventional products address all scenarios with fixed configurations, forcing users either to pay a premium for features they don’t need or to compromise on critical performance metrics. UPECS overcomes this dilemma through its modular architecture.

The system comprises seven major functional modules—ranging from the main cabinet frame and airflow circulation system to the integrated clean‑air filtration system—allowing users to tailor the configuration to their specific application needs. More importantly, the modular architecture helps shorten on‑site installation timelines and minimizes disruption to production schedules.

Intelligent Control: From Passive Response to Proactive Regulation

The Jice High-Precision Environmental Control System, UPECS, achieves stable temperature control in critical zones through a multi‑stage temperature‑regulation patent technology. Conventional environmental control systems typically rely on feedback from a single temperature sensor, resulting in lagged adjustments; by the time the sensor detects a deviation, temperature gradients may already have developed within the space. UPECS employs a vertical unidirectional airflow design, continuously acquiring real‑time data on temperature, humidity, and air pressure to actively counteract environmental disturbances. This approach effectively prevents temperature overshoot and oscillatory fluctuations, fundamentally ensuring the stability and reproducibility of long‑duration processes.

The system supports both remote operations and maintenance and data traceability. Historical trend curves for environmental parameters can be queried and exported, while abnormal conditions automatically trigger an alert mechanism, providing a reliable “environmental black box” for precision manufacturing applications.

From semiconductors to precision optics: comprehensive, all‑scenario coverage

The application scope of Jice’s ultra‑high‑precision environmental control system, UPECS, spans numerous fields that are highly sensitive to micro‑environmental conditions. In semiconductor manufacturing, processes such as lithography, bonding, and inspection impose extremely stringent requirements on temperature‑field uniformity and cleanliness; UPECS delivers millikelvin‑level temperature control and an ISO Class 1 clean environment, providing foundational reliability to ensure yield. In the precision optics sector, the fabrication and testing of large‑aperture optical components are equally sensitive to airflow disturbances and micro‑vibrations, and UPECS creates a stable environmental space for optical manufacturing. Moreover, in high‑end metrology, advanced materials processing, and precision aerospace assembly, UPECS serves as an indispensable environmental infrastructure.

At the same time, Jice possesses the capability to deliver non‑standard, deeply customized solutions tailored to specific industries and processes—whether it’s the range of environmental parameters, equipment dimensions, module configuration options, or external interfaces and communication protocols, all can be adjusted to meet precise requirements. In Jice’s view, true high‑precision environmental control is never a matter of “choosing a model”; rather, it involves “designing a solution” for a one‑of‑a‑kind application scenario.

Jice commits to “precision temperature control within ±0.002℃” and is dedicated to becoming a trusted, long-term technology partner in the high-precision environmental control field.
