How to use pre-wetted dust-free cloth in laboratory PCB cleaning

Posted on by

Pre-moistened cleanroom wipes are essential for efficient and contaminant-free PCB cleaning in laboratory and controlled environments. These wipes are saturated with high-purity solvents, allowing uniform removal of dust, oils, flux residues, and fingerprints without generating lint or particles. Key operational methods include selecting appropriately sized wipes for different PCB areas, using gentle unidirectional strokes to avoid redistributing contaminants, and employing multiple wipes sequentially for heavily soiled regions. Pre-moistened wipes are compatible with solvents such as isopropyl alcohol and deionized water, ensuring safe use on delicate PCB assemblies and electronic components. Proper technique improves cleaning efficiency, maintains PCB integrity, and reduces the risk of short circuits or contamination-related failures.

Features:

  • Pre-saturated with high-purity, residue-free solvents

  • Lint-free and low-particulate for delicate surfaces

  • Ensures uniform contaminant removal

  • Safe for PCB assemblies and electronic components

Application Scope:

  • Laboratory PCB cleaning and maintenance

  • Semiconductor and microelectronics facilities

  • Cleanroom and precision electronics environments

  • ESD-sensitive electronic components

IPA rag alcohol operation specifications and precautions

Posted on by

Isopropyl alcohol (IPA) wipes are widely used for cleaning sensitive surfaces in laboratories, electronics, and precision equipment. Proper usage ensures effective contaminant removal while protecting delicate surfaces. The recommended procedures include selecting an appropriate wipe size, using pre-moistened IPA wipes for uniform coverage, and applying gentle unidirectional strokes to avoid scratches or particle redistribution. For heavily soiled areas, multiple wipes can be used sequentially. Key precautions include avoiding excessive pressure, ensuring proper ventilation, keeping wipes sealed when not in use to prevent solvent evaporation, and adhering to ESD safety measures in sensitive electronics areas. Following these protocols enhances cleaning efficiency, prolongs equipment lifespan, and maintains a contaminant-free environment.

Features:

  • Lint-free and residue-free for delicate surfaces

  • Pre-moistened for consistent cleaning

  • Fast-drying and safe for metals, glass, plastics, and coated optics

  • Reduces contamination and protects sensitive equipment

Application Scope:

  • Laboratory instruments and surfaces

  • Electronic components and PCB assemblies

  • Optical lenses and precision equipment

  • Cleanroom and controlled environment maintenance

Usage Comparison: Anti-Static vs. Wet Wipes

Posted on by

Understanding the distinction between antistatic cleanroom wipes and general cleaning wet wipes is essential for maintaining contamination-free and ESD-safe environments.

Key Features:

  1. Antistatic Cleanroom Wipes: Lint-free, non-abrasive, designed to prevent electrostatic discharge on sensitive equipment.

  2. Cleaning Wet Wipes: Pre-moistened for general cleaning, may not be ESD-safe or suitable for delicate surfaces.

  3. High Absorbency: Both types remove dust, oils, and residues effectively, but cleanroom wipes are optimized for precision environments.

  4. Chemical Compatibility: Cleanroom wipes resist IPA, deionized water, and approved solvents; general wet wipes may degrade under certain chemicals.

Usage Differences:

  • Application Areas:

    • Antistatic cleanroom wipes: Electronics, optics, laboratories, and cleanroom surfaces.

    • Cleaning wet wipes: General surfaces, desks, and non-sensitive equipment.

  • ESD Protection: Only antistatic wipes prevent electrostatic discharge during cleaning.

  • Surface Safety: Cleanroom wipes are non-abrasive for delicate surfaces; wet wipes may leave fibers or residues.

  • Sterility and Cleanroom Class: Cleanroom wipes comply with ISO Class 100–1000 standards; wet wipes do not.

Benefits:

  • Antistatic Wipes: Protect sensitive electronics, maintain particle-free environments, and ensure compliance with cleanroom standards.

  • Cleaning Wet Wipes: Quick general cleaning, convenient for low-risk surfaces, cost-effective.

  • Enhanced Efficiency: Using the correct wipe type improves cleaning outcomes and protects equipment.

  • Contamination Control: Cleanroom wipes minimize cross-contamination and maintain surface integrity.

Anti-Static Wipes: Procedures & Standards

Antistatic cleanroom wipes are essential for maintaining contamination-free and ESD-safe environments. Following proper cleaning procedures ensures equipment protection and compliance with cleanroom standards.

Key Features:

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

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

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

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

Cleaning Procedures:

  • Preparation: Wear gloves and ensure wipes are sealed until use.

  • Surface Assessment: Identify areas with high contamination or particle accumulation.

  • Unidirectional Wiping: Use consistent strokes from clean to dirty areas to avoid redistributing particles.

  • Tool Handling: Use single-use wipes; avoid touching the cleaned surface with bare hands.

  • Inspection: Check surfaces post-cleaning to ensure residue-free and particle-free results.

Operation Guidelines:

  • Storage: Keep wipes in sealed containers in a dry, dust-free environment.

  • Controlled Use: Use only the required number of wipes to maintain efficiency and reduce waste.
