We are committed to developing a domestically developed CAE/CFD platform and 3D model retrieval software, specializing in providing digital simulation and design solutions for optimizing design, reducing energy consumption and emissions, and lowering costs and increasing efficiency for fields such as biomedicine and disease transmission, high-end materials manufacturing, cleanroom engineering, data centers, energy storage and thermal management, and heavy industry.
In high-end manufacturing fields like semiconductor manufacturing, biomedicine, and precision optics, a single tiny dust particle can cause the entire production process to fail. Research shows that in integrated circuit chip manufacturing, every increase of 1,000 particles/ft³ of dust particles larger than 0.3μm increases the chip defect rate by 8%. In sterile pharmaceutical production, excessive levels of floating bacteria can lead to the scrapping of entire batches of products. Cleanroom, the cornerstone of modern high-end manufacturing, safeguard the quality and reliability of innovative products through precise micron-level control. Computational fluid dynamics (CFD) simulation technology is revolutionizing traditional cleanroom design and optimization methods, becoming the engine of a technological revolution in cleanroom engineering. Semiconductor Manufacturing: The War Against Micron-Scale Dust. Semiconductor chip manufacturing is one of the fields with the most stringent cleanroom requirements. The photolithography process is extremely sensitive to particles as small as 0.1μm, making these ultrafine particles virtually impossible to detect with traditional detection equipment. A 12-inch wafer fab, employing high-performance laser dust particle detectors and advanced clean technology, successfully controlled the concentration fluctuation of 0.3μm particles to within ±12%, increasing product yield by 1.8%.
Biomedicine: The Guardian of Bacterial Production
In the production of sterile pharmaceuticals and vaccines, cleanroom is crucial for preventing microbial contamination. Biomedical cleanroom not only require controlled particle concentrations but also maintain appropriate temperature, humidity, and pressure differentials to prevent cross-contamination. After implementing an intelligent cleanroom system, a vaccine manufacturer reduced the standard deviation of suspended particle counts in its Class A area from 8.2 particles/m³ to 2.7 particles/m³, shortening the FDA certification review cycle by 40%.
Aerospace
The precision machining and assembly of aerospace components requires a cleanroom environment. For example, in the machining of aircraft engine blades, tiny impurities can cause surface defects, impacting engine performance and safety. The assembly of electronic components and optical instruments in aerospace equipment also requires a clean environment to ensure proper function in the extreme conditions of space.
Precision Machinery and Optical Instrument Manufacturing
In precision machining, such as the production of high-end watch movements and high-precision bearings, cleanroom can reduce the impact of dust on precision components, improving product accuracy and service life. The manufacturing and assembly of optical instruments, such as lithography lenses and astronomical telescope lenses, can be performed in a clean environment to prevent surface defects such as scratches and pitting, ensuring optical performance.
CFD Simulation Technology: The "Digital Brain" of Cleanroom Engineering
Computational fluid dynamics (CFD) simulation technology has become a core tool for cleanroom design and optimization. Using numerical analysis methods to predict fluid flow, energy transfer, and other related physical behaviors, it significantly improves cleanroom performance. CFD technology for airflow optimization can simulate cleanroom airflow and optimize the location and design of supply and return air vents. A study has shown that by properly arranging the location and return air pattern of fan filter units (FFUs), even with a reduced number of hepa filters at the end, a higher cleanroom rating can be achieved while achieving significant energy savings.
Future Development Trends
With breakthroughs in fields like quantum computing and biochips, cleanliness requirements are becoming increasingly stringent. Quantum bit production even requires an ISO Class 0.1 cleanroom (i.e., ≤1 particle size per cubic meter, ≥0.1μm). Future cleanrooms will evolve towards higher cleanliness, greater intelligence, and greater sustainability: 1. Intelligent Upgrades: Integrating AI algorithms to predict particle concentration trends through machine learning, proactively adjusting air volume and filter replacement cycles; 2. Digital Twin Applications: Building a three-dimensional cleanliness digital mapping system, supporting VR remote inspections, and reducing actual commissioning costs; 3. Sustainable Development: Utilizing low-carbon refrigerants, solar photovoltaic power generation, and rainwater recycling systems to reduce carbon emissions and even achieve "zero-carbon cleanroom".
Conclusion
Cleanroom technology, as the invisible guardian of high-end manufacturing, is continuously evolving through digital technologies like CFD simulation, providing a cleaner and more reliable production environment for technological innovation. With the continuous advancement of technology, cleanroom will continue to play an irreplaceable role in more high-end fields, safeguarding every micron of technological innovation. Whether it is semiconductor manufacturing, biomedicine, or optical and precision instrument manufacturing, the synergy between cleanroom and CFD simulation technology will drive these fields forward and create more scientific and technological miracles.
