company news about Products Used in Cleanrooms: ESD Clothing and Accessories

Cleanrooms are critical environments for maintaining stringent cleanliness standards, especially in industries such as electronics, semiconductors, and pharmaceuticals. To ensure these high standards are met and minimize contamination, it is essential to use specially designed electrostatic discharge (ESD) products. These products not only maintain cleanliness but also protect sensitive equipment and materials from electrostatic discharge (ESD), which can cause severe damage.

ESD Clothing and Accessories

In a cleanroom, static electricity can cause serious damage to sensitive equipment such as microchips, circuit boards, and other electronic components. To prevent the accumulation of static electricity, cleanroom personnel are required to wear ESD clothing and accessories. These products help safely discharge static electricity, ensuring the environment remains contaminant-free.

ESD Clothing

ESD clothing is one of the most basic items in a cleanroom. These garments are made of conductive fibers that help release static electricity, preventing it from accumulating on the surface of the human body. Common types of ESD clothing used in cleanrooms include:

ESD Coveralls: Full-body suits made from special fabrics designed to prevent static buildup. These coveralls are usually woven with conductive threads to ensure any static is safely released.

ESD Lab Coats or Jackets: Worn over regular clothing, these are designed to protect the cleanroom environment from particle contamination that may be released by personal clothing.

ESD Gloves: Made from rubber or nitrile, these gloves prevent static from transferring to the objects being handled while also protecting workers from potentially harmful chemicals or particles inside the cleanroom.

ESD Footwear

Footwear is another critical part of static control in cleanrooms. Personnel need to wear special ESD shoes or boots to prevent static buildup when walking on the cleanroom floor. Common types include:

ESD Shoes: Made from conductive materials, these shoes help discharge static as the worker moves.

ESD Heel Straps: Typically worn with regular shoes, these straps provide grounding to prevent static buildup.

ESD Wrist Straps

Wrist straps are another essential accessory in cleanrooms. They are worn around the wrist and connected to a grounding point to safely release any static that may accumulate on the body. These straps are especially important for workers handling sensitive electronic components, as they provide continuous protection against the risk of electrostatic discharge.

ESD Hoods and Hair Nets

To provide maximum protection, cleanroom personnel often wear ESD hoods and hair nets. These hoods ensure that a worker’s head and hair do not transfer particles or static into the cleanroom. The materials used are similar to those in coveralls, with conductive properties to help discharge any accumulated static.

Static Measurement and Discharge Before Entering the Cleanroom

Before entering the cleanroom, personnel must take several steps to ensure they are not carrying static electricity into the controlled environment. This process is crucial for maintaining the integrity of the cleanroom and preventing contamination or damage to sensitive equipment. Common procedures include:

Static Measurement

Prior to entering the cleanroom, personnel usually undergo static measurement. This is typically done using an electrostatic field meter or electrostatic voltmeter to detect and measure the amount of static on the person’s clothing or body. If the reading exceeds acceptable levels, the worker may need to take additional steps to discharge the static before entering the cleanroom.

ESD Stations

Cleanroom facilities typically have designated ESD stations where personnel can safely discharge any accumulated static. These stations usually include grounding mats, ESD shoes, wrist straps, and other tools to help neutralize static. Workers must use these stations to discharge static before entering the cleanroom to ensure they are properly grounded.

Ionizing Devices

Some cleanrooms also use ionizing devices designed to neutralize static in the air. These devices release positive and negative ions to balance the electrical charges in the environment. This is especially important for high-precision tasks, as it ensures that static does not accumulate in the air throughout the area.

Conclusion

The use of ESD clothing and accessories is crucial to maintaining the integrity of a cleanroom environment. These products, including ESD coveralls, wrist straps, and more, ensure that workers do not introduce contaminants or static that could damage sensitive equipment or products. In addition, the process of static measurement and discharge before entering the cleanroom further helps to mitigate the risks of electrostatic discharge. As industries like electronics and pharmaceuticals continue to advance, static control in cleanrooms will remain vital in ensuring product quality and operational efficiency.
