Case study on the use of cleaning wipes in a Class 100 cleanroom

Cleaning wipes are critical in maintaining particle-free, ESD-safe environments in Class 100 (ISO 5) cleanrooms. Proper usage ensures equipment protection and regulatory compliance.

Key Features:

  1. Lint-Free and Non-Abrasive: Prevents fiber contamination and surface scratches.

  2. Antistatic Properties: Minimizes electrostatic discharge (ESD) risks on sensitive electronics.

  3. High Absorbency: Efficiently removes dust, oils, and residues.

  4. Chemical Compatibility: Safe for use with IPA, deionized water, and approved disinfectants.

Usage Case Examples:

  • Electronics Assembly: Wipes used to clean PCBs, sensors, and microchips, preventing particle contamination.

  • Optical Instruments: Lenses and microscopes wiped to maintain clarity and accuracy.

  • Laboratory Equipment: Benches, glassware, and analytical devices cleaned to avoid cross-contamination.

  • Cleanroom Surfaces: Floors, counters, and instruments maintained in ISO Class 100 conditions.

Best Practices:

  • Unidirectional Wiping: Clean to dirty strokes to avoid particle redistribution.

  • Pre-Wetted Option: Use IPA or deionized water for faster, residue-free cleaning.

  • Single-Use Handling: Discard wipes after each task to maintain sterility.

  • Inspection: Ensure surfaces are residue-free and particle-free post-cleaning.

Benefits:

  • Maintains Cleanroom Standards: Keeps Class 100 environments particle-free.

  • Protects Sensitive Equipment: ESD-safe, lint-free wipes reduce contamination and damage.

  • Improves Cleaning Efficiency: High absorbency reduces time and effort.

  • Supports Regulatory Compliance: Aligns with ISO and GMP standards.
