Understanding the Characteristics of Cleanroom Anti-Static Wipes

Posted on by

Cleanroom anti-static wipes are specialized cleaning tools designed for use in cleanroom environments, featuring anti-static properties and high cleanliness levels. They are widely used in industries such as semiconductors, electronics manufacturing, pharmaceuticals, optics, and biotechnology, where strict requirements for static control and cleanliness are essential. To ensure product quality and process stability, it is crucial to understand the characteristics of cleanroom anti-static wipes. This article provides a detailed overview of the main features, advantages, and applications of these wipes.

1. Anti-Static Properties

a. Low Static Generation

Cleanroom anti-static wipes are made from special fibers and treated with anti-static technology, effectively reducing static electricity generation. This helps prevent potential damage to sensitive electronic components and equipment during cleaning.

b. Stable Surface Resistivity

The surface resistivity of anti-static wipes typically ranges from 10^6 to 10^9 ohms, ensuring consistent anti-static performance in cleanroom environments and preventing static interference with products.

2. High Cleanliness

a. Low Particle Generation

Made from high-quality polyester or nylon synthetic fibers and treated with specialized dust-free processes, anti-static wipes minimize particle shedding during use, making them suitable for environments with strict cleanliness requirements.

b. Laser or Ultrasonic Sealed Edges

Most anti-static wipes feature laser or ultrasonic sealed edges, preventing edge fraying and further enhancing the wipe’s cleanliness and durability.

3. Excellent Absorption Performance

a. High Absorption of Water and Oils

Anti-static wipes possess strong absorption capabilities for both water and oils, allowing them to quickly absorb liquids and contaminants, ensuring effective cleaning. Their structure maintains anti-static properties even when wet.

b. Solvent Compatibility

These wipes are compatible with various cleaning solvents, such as isopropyl alcohol and deionized water, enabling efficient removal of grease, stains, and particulate contaminants.

4. Chemical Resistance and Durability

a. Chemical Resistance

Anti-static wipes are resistant to various chemicals, maintaining stable physical properties when used with cleaning solvents, and are not easily corroded or broken down by them.

b. Durability

Constructed with a double-layer knit or high-density weave, anti-static wipes are highly durable and resistant to wear, ensuring long-term use without compromising their cleaning effectiveness.

5. Soft and Non-Abrasive Surface

The soft material of anti-static wipes ensures they won’t scratch or damage delicate surfaces, making them suitable for cleaning precision instruments, electronic components, optical lenses, and other sensitive equipment. Their soft texture allows them to reach small crevices and complex surfaces for thorough cleaning.

6. Application Scenarios

a. Electronics Manufacturing and Semiconductor Industry

Used for cleaning wafers, chips, LCD screens, and printed circuit boards (PCBs), preventing static damage to electronic components.

b. Pharmaceuticals and Biotechnology

Used to clean equipment and instruments in pharmaceutical production and laboratory operations, maintaining a dust-free and anti-static environment.

c. Optics and Precision Instruments

Ideal for cleaning optical lenses, microscopes, and camera lenses, ensuring dust-free surfaces without static interference.

d. Automotive and Aerospace Industries

Suitable for cleaning automotive parts, aviation instruments, and other static-sensitive equipment, ensuring stability and safety.

ESD dust removal sticks for Class 10-100 cleanrooms, made from ultra-clean, anti-static materials. Ideal for safely removing dust from sensors, LEDs, and LCDs without leaving residues or scratches

ESD Dust Removal Sticks for High-Cleanliness Environments

Posted on by

ESD dust removal sticks are specifically designed for high-cleanliness environments (Class 10-100). They are made from highly clean, non-dusting, and low-ion content materials that do not contain allergens. These sticks offer excellent chemical corrosion resistance, and their anti-static treatment safely dissipates charges without being affected by environmental changes. They are suitable for cleaning and assembling electrostatic-sensitive products.

1. Applications:

  • Excellent Adhesion: Ideal for cleaning micro-dust ions on exposed sensor surfaces in COB (Chip-on-Board) processes. Unlike ordinary cotton swabs (which use cleaning water on CSP sensor surface glass), these sticks do not produce dust points, do not scratch the sensor, and do not leave stains, significantly improving product yield.
  • Particle Removal: Effective for removing particles from LED/LCD surfaces in Class 10-5000 cleanrooms and cleaning lens surface debris.

2. Features:

  1. Special Adhesive: Custom adhesive formulation, non-volatile, and non-shedding.
  2. Soft and Resilient: Provides good flexibility and operational feel. Environmentally friendly, non-irritating odor, and harmless to users.
  3. Protects Product: Offers excellent protection for both the electrical and physical appearance of the product.

3. Operating Instructions:

  1. Packaging Removal: Remove the outer packaging and clean the dust removal stick’s outer packaging before entering the cleanroom through an air shower.
  2. Pre-Operation Preparation: Perform a 5S check (Sort, Set in order, Shine, Standardize, Sustain) on the work surface, floor, equipment, chairs, gloves, tools, fixtures, trays, etc., and inspect with a microscope.
  3. Handling: Use tweezers to gently pick up the stick from the tray. Avoid contact with objects to prevent contamination. Hold the other end with your hand and prepare for use.
  4. Usage: Align the stick with the dust spot under a microscope or software. Maintain a 60°-90° angle and gently apply the stick without excessive force to avoid scratching or damaging the sensor.
  5. Stability: Hold the stick steady, avoid shaking or moving it back and forth, and do not rub it on the product to prevent scratches.
  6. Frequency: Do not use the same stick to clean more than ten times to avoid secondary contamination.
  7. Post-Use: Keep used sticks away from the work area, separated from clean sticks.
