Cleanrooms are core controlled environments in industries such as precision manufacturing, biomedicine, and electronic semiconductors. Their construction quality directly determines the stability of key indicators such as cleanliness, pressure differential, and airflow organization. Compared to explicit construction defects, latent quality hazards left over from the construction phase are characterized by their concealment, delayed effects, and stubbornness. They are difficult to detect during the final acceptance phase and can easily lead to problems such as exceeding cleanliness standards, microbial growth, and equipment malfunctions after commissioning, significantly increasing operation and maintenance costs and even affecting product yield and production compliance. This article identifies high-frequency latent quality hazards in cleanroom construction, analyzes their causes, and clarifies key prevention and control points, providing a reference for cleanroom engineering quality management.

In today's rapidly developing precision manufacturing and high-tech industries, "cleanrooms" are no longer the exclusive domain of a few cutting-edge companies, but have become common infrastructure for ensuring product quality. Among them, Class 100,000 cleanrooms, with their moderate cleanliness level and relatively controllable construction and operating costs, have become one of the most widely used clean environments. So, what production needs can they meet? Which industries cannot function without them? And what irreplaceable boundaries do they have?

In high-end manufacturing fields such as biomedicine, semiconductors, precision electronics, medical devices, and new materials, cleanrooms are core infrastructure for ensuring product quality and meeting compliance requirements. For a long time, traditional civil engineering cleanrooms have dominated the market due to their stability. However, with accelerated industrial iteration, frequent production capacity fluctuations, the normalization of factory leasing, and increased demand for enterprise relocation and expansion, relocatable and reusable modular cleanrooms are rapidly replacing traditional models and becoming the preferred choice for more and more companies.

Modular cleanrooms, with their advantages of flexible assembly, rapid deployment, and relocation, are widely used in industries with strict cleanliness requirements, such as electronics, pharmaceuticals, biology, and food. Compared with traditional cleanrooms, while modular structures offer greater stability and convenience, the standardization of daily maintenance directly determines their ability to maintain cleanliness levels and their service life.
