Cleanroom Construction for Precision Industries - Nanjing Expansion Technology (On-site visits available)

In the dust-free workshops of semiconductor chip manufacturing, even tiny dust particles can cause millions of dollars worth of chips to be scrapped; in biopharmaceutical R&D laboratories, a trace of bacterial contamination can ruin years of research. In these fields with almost demanding environmental requirements, cleanrooms, as the "sterile fortresses" of modern industry and scientific research, are playing an irreplaceable role. This article will provide an in-depth analysis of the mysteries of cleanrooms, revealing why they have become the quality guardians of numerous industries.

I. Cleanroom: Precise Environmental Control "Magic Space" ​

A cleanroom refers to a specially designed room that removes particulate matter, harmful air, bacteria, and other pollutants from the air within a certain spatial range, and controls the indoor temperature, cleanliness, indoor pressure, air flow speed and distribution, noise and vibration, lighting, and static electricity within a certain required range. Simply put, it is a special space that achieves high cleanliness, constant temperature and humidity, and stable airflow through professional equipment and technology. ​

According to the international standard ISO 14644-1, cleanrooms can be divided into different grades from ISO 1 (highest cleanliness, no more than 10 particles ≥0.1μm per cubic meter of air) to ISO 9 (no more than 35,200,000 particles ≥0.5μm per cubic meter of air), to meet the differentiated needs of various industries. ​

II. Cleanroom's "Eighteen Martial Arts": Wide Application in Multiple Fields ​

(1) Semiconductor and Electronics Industry ​

In the semiconductor chip manufacturing process, the line width of the circuit has been reduced to the nanometer level. A tiny dust particle can cause a short circuit or open circuit, resulting in chip failure. The cleanroom, through a high-efficiency filtration system and strict airflow control, controls the concentration of suspended particles in the air to an extremely low level, providing an ideal "zero-pollution" environment for the precise manufacturing of chips, ensuring product yield and performance stability. “Zero-pollution” ideal environment, ensuring product yield and performance stability. ​

(2) Biopharmaceutical Field ​

From drug R&D and production to medical device manufacturing, all must be carried out in a clean environment to prevent microbial contamination and cross-infection. Cleanrooms not only effectively control the number of microorganisms in the air, but also precisely adjust temperature, humidity, and air pressure, providing reliable assurance for drug quality and safety. It is a key facility for the biopharmaceutical industry to comply with GMP (Good Manufacturing Practice) standards. ​

(3) Food and Beverage Industry ​

To ensure food safety, the production process of food and beverages needs to strictly control microbial and dust contamination. Cleanrooms, through strict management of air, personnel, equipment, and materials, create a clean and hygienic environment for food and beverage production, effectively extending product shelf life, and improving product quality and consumer confidence. ​

(4) Aerospace and Precision Instrument Manufacturing ​

The manufacturing and assembly of components in the aerospace field have extremely high requirements for environmental cleanliness. Any tiny impurities can affect the performance and reliability of the equipment. Cleanrooms can provide stable temperature and humidity and a clean air environment, ensuring the high-precision manufacturing and assembly of aerospace components and precision instruments, and guaranteeing the normal operation of products in extreme environments. ​

III. Three Core Advantages of Choosing a Cleanroom ​

(1) Improve Product Quality ​

Strict environmental control can effectively reduce the pollution and adverse factors affecting products during production, reduce the defect rate, improve product consistency and stability, and lay a solid foundation for enterprises to create high-quality products. ​

(2) Reduce Production Costs ​

Although the initial construction and operating costs of cleanrooms are relatively high, in the long run, it can significantly reduce rework, scrap, and recall costs caused by product quality problems, while improving production efficiency and bringing higher economic benefits to enterprises. ​

(3) Ensure Personnel Health and Safety ​

In the biopharmaceutical, chemical, and other industries, cleanrooms not only protect products but also effectively isolate harmful gases, dust, and microorganisms, providing a safe and healthy working environment for staff and reducing occupational health risks. ​

IV. How to Choose a Cleanroom Suitable for You? ​

(1) Clarify Needs and Grade Standards ​

Based on the characteristics of your industry and production process requirements, determine the required cleanroom grade and environmental parameters. For example, semiconductor chip manufacturing usually requires ISO 1 - ISO 4 ultra-high cleanliness environment, while food and beverage production generally only needs to reach ISO 7 - ISO 8 to meet the requirements. ​

(2) Investigate Supplier Strength ​

Choose a cleanroom supplier with rich experience and professional qualifications, review their past cases and customer reviews, and ensure that they have the ability to design, construct, and maintain high-quality cleanrooms. At the same time, pay attention to the supplier's after-sales service system to ensure that problems can be solved promptly during the operation of the cleanroom. Nanjing Expansion Technology has undertaken numerous cleanroom projects, such as: Wuhan Light Source Pre-research Base 。 This project includes multiple sets of high-standard environmental control systems and precision experimental environment integration devices. The main functions are magnetic measurement laboratory, beam measurement laboratory, beam line optics laboratory, high-frequency laboratory 10,000-grade room, high-frequency laboratory 100-grade room, linear accelerator laboratory, and vacuum laboratory. Some project sites can be visited. Welcome to inquire.

(3) Focus on Equipment and Technology Configuration ​

Core equipment for cleanrooms, such as air filters, air conditioning systems, and temperature and humidity control systems, directly affect their performance and operating efficiency. Choosing advanced and reliable equipment and using an intelligent monitoring and management system can achieve precise control and real-time monitoring of the cleanroom environment, improving operating efficiency and stability. ​

From chip manufacturing to pharmaceutical R&D, from food production to aerospace engineering, cleanrooms, with their superior environmental control capabilities, safeguard the high-quality development of various industries. Whether it's a new project or an upgrade, choosing the right cleanroom solution is a crucial step for companies to enhance their competitiveness and achieve sustainable development.
