In industries with extremely high cleanliness requirements such as electronics optics, semiconductor manufacturing, and biopharmaceuticals, cleanroom wipes are essential consumables that ensure process stability and product quality. A high-quality cleanroom wipe must not only have excellent cleaning efficiency but also meet strict physical, chemical, and biological standards. This article analyzes the seven core performance parameters that high-quality cleanroom wipes should satisfy, helping enterprises make precise selections to improve cleanroom process stability and product yield.
1. Strict Control of Particle Shedding
Particle shedding during use directly affects the cleanliness level.
-
Visible Particles: The wipe should not shed visible fibers or particles to avoid scratching or secondary contamination. High-density weaving and laser or ultrasonic sealing reduce fiber breakage risk.
-
Submicron Particles: The release of submicron particles must be measured by laser particle counters and comply with ISO 14644-1 standards. Using ultrafine fibers combined with multiple rounds of ultrapure water cleaning improves cleanliness.
2. Fiber Shedding Suppression
Fiber residue is a major concern affecting wiping effectiveness and equipment safety.
-
Use nonwoven fabrics or woven fabrics sealed by laser cutting or ultrasonic welding.
-
Comply with IEST-RP-CC004.3 fiber release testing to ensure particle emissions meet strict criteria.
3. Extremely Low Chemical Residue
High cleanliness applications are sensitive to chemical contamination and require strict control of ions and non-volatile residues (NVR).
-
Ion Contamination: Tested per IPC TM-650 2.3.28 to ensure no soluble ionic contamination.
-
Non-Volatile Residues: Use ultrapure water cleaning and solvent-free manufacturing to prevent organic or inorganic deposits that may corrode equipment or affect chemical reactions.
4. Biological Load Control
Especially in pharmaceutical and biological labs, wipes must meet sterile or low microbial load standards.
-
Sterilization treatments reduce microbial counts.
-
Packaging with double clean bags or vacuum sealing prevents contamination during transport and storage.
5. Anti-Static Performance
Electrostatic discharge (ESD) can damage sensitive electronic components; high-quality wipes need stable anti-static properties.
-
Surface resistivity should range between 10⁵ to 10⁹ ohms, complying with ANSI/ESD S20.20 standards.
-
Permanent anti-static additives such as carbon fibers or conductive threads are preferred over temporary coatings.
6. Clean Packaging and Traceability
-
Class 100 wipes must be packaged in Class 100 cleanrooms to avoid external contamination.
-
Provide detailed batch test reports including particle counts, ion content, and microbial data, meeting ISO 9001 quality management requirements.
Summary
High-quality cleanroom wipes are vital guardians of precision manufacturing and R&D, with performance spanning material selection, manufacturing processes, stringent testing, and clean packaging. When selecting wipes, users should consider specific application requirements, reference industry standards, and verify through third-party testing to ensure optimal particle shedding, chemical contamination, biological safety, electrostatic control, and traceability. Only wipes that balance these multidimensional performance factors can truly act as the “invisible protectors” of clean environments, helping enterprises continuously enhance product quality and process stability.
