The Class 100 workshop is called Class 100 because of its cleanliness, the number of particles with a particle size greater than or equal to 0.1 microns cannot be greater than 100. The concept that there can be no more than 100 dusts of 0.1 microns in the workshop is what it is all about. So in the protection requirements above strict, do not think that the choice of dust-free clean gloves will not care, this idea is wrong.

Each industry has different requirements for clean rooms, which are graded as 10w, 10,000, 1,000, 100 and 10 (the smaller the number, the higher the clean room grade). Generally speaking the clean room for the food processing industry is class 10w, the electronic industry has relatively high requirements for clean rooms, but a class 10,000 clean room is sufficient for its use, and most clean products are of a higher class than the clean room.

The details of clean gloves are also particularly important, which clean gloves are used in class 100 areas. The following is a list of the details you need to pay attention to when choosing clean gloves for class 100 workshops:

Each industry has different requirements for clean rooms, which are classified as 10w, 10,000, 1,000, 100 and 10 (the smaller the number, the higher the clean room level). Generally speaking, clean rooms in the food processing industry are class 10w and in the electronics industry the requirements for clean rooms are relatively high, but a class 10,000 clean room is sufficient for its use and most clean products are of a higher class than clean rooms.

To sum up, a class 100 clean room should wear class 100 dust-free clean gloves!

WootC nitrile gloves do not contain latex proteins and will not cause allergic reactions. They are also anti-static, ageing and oil resistant and are shaped according to the shape of the human hand, with great sensitivity, excellent stretching and puncture resistance, high tensile strength and excellent abrasion resistance and cleanliness.

Nitrile gloves are mainly processed from nitrile rubber and are used in opto-electronic factories, medical, pharmaceutical, hygiene, food processing and other operating industries to prevent the hand from touching and holding products in the process of production to prevent falling and sweaty hands causing poor product protection.

The main properties are puncture resistance, oil and solvent resistance, fingertip linen treatment to avoid slipping of the apparatus when using, high tensile strength to avoid tearing when wearing, effective to avoid skin allergy caused by powder and cause poor products.

Relative Humidity Control

Humidity control is important for an effective ESD program for two primary reasons;

At lower humidity levels (< 30% RH), the dissipation of commonly generated static charges does not take place, thus adding to the probability of ESD events.

Materials (such as pink poly) rely on the moisture in the air to combine with the material’s antistatic agent to form a microscopic conductive layer over the entire surface of the material. At lower humidity, (typically below 15% RH) these antistatic materials can become charged, creating an ESD hazard.

The optimum relative humidity in an EPA is 50% (plus or minus 10%).

When humidity falls below 30% RH, ESDS devices and assemblies shall be processed using special controls and procedures such as air ionization and increased awareness of the greater potential for triboelectric charging. The Facility ESD Monitor must verify the humidity prior to each shift or operation if work is not shift based unless an automatic low humidity alarm system is monitoring the work area. It is highly recommended that facility air handlers include automatic humidifiers to maintain humidity control. EPAs shall control relative humidity within a range of 30 to 70 percent relative humidity.

Air Ionizers

Air ionizers can neutralize the static charge on insulators or isolated objects by charging the molecules of the surrounding area that causes the accumulated charge to be neutralized. Air ionizers are generally used when it is not possible to properly ground everything at the workstation using previously described methods and equipment or as a back up to those methods.

As an example, most adhesive tapes are nonconductors and would require an ionizer to neutralize the charge on the tape if used in close proximity to ESDS devices. An ionizer shall be used at all, times when work is being performed in a Class 1 facility and must be available for use when needed in a Class 2 facility. Ionizers are specifically required for use in some manufacturing operations that generate static charges such as vapor degreasing, vacuum packing, spraying conformal coating, wave soldering, and the use of pressurized air guns. In addition, ionizers are a recognized static charge deterrent when humidity falls below 30 % RH. Any part sensitive to damage below 250 volts requires that an ionizer be used any time the part is removed from its ESDS packaging. Calibration of the air ionizer to verify balance and performance is required.
