Semiconductor production industry

In the semiconductor production workshop, due to the adsorption of dust on the chips, especially the output of very large-scale integrated circuits will be greatly reduced. All operators in the production workshop wear clean work clothes. When carrying and placing electronic products, anti-static wrist straps should be worn .If the human body has static electricity, it is easy to absorb dust and dirt. If these dust and dirt are brought to the work site, it will directly affect product quality, increase the defective rate, and greatly reduce the yield rate. If the radius of the adsorbed dust particles is larger than the width of the line, and When there is a film thickness, the product is very likely to be scrapped.

Therefore, it is necessary to wear anti-static clothing, anti-static wrist straps and anti-static ankle straps during processing, production and packaging. Chip products such as computer appliances have stricter requirements for static electricity. In order to ensure the normal operation of the production line, Carry out overall decoration of its clean factory with anti-static building materials, and take hardware measures such as equipping all personnel entering and leaving the clean factory with anti-static clothing. Packaging companies can formulate corporate standards or put forward specific anti-static requirements based on relevant national standards and the actual situation of the company. , to cooperate with the normal operation of the packaging production line.

Precision machinery industry

Dust-free clothing is made of anti-static ultra-clean fabric. In addition to anti-static properties, another outstanding feature of this fabric is dust-free and dust-filtering properties, so that employees wearing dust-free clean clothing will not dust when entering the dust-free workshop. Bringing it into the workshop, you only need to wear an anti-static wrist strap during production to prevent static electricity from damaging the product; the good dust filtration performance of the dust-free suit means that the human body emits less dust particles into the air. In many cases, the product Whether it is qualified or not depends on the amount of dust attached or the impact of dust on the product. Therefore, the quality of dust-free clothing is closely related to the product qualification rate. At the same time, dust-free clothing needs to be cleaned regularly. On the one hand, it is to ensure the cleanliness and anti-static performance of the clothes .On the other hand, it eliminates sweat and odor and reduces the discomfort of the wearer.

Mobile phone manufacturing industry

In most industrial processes, static electricity will accumulate, causing products to be scrapped and people to be injured. Even during loading, unloading and transportation, fire and explosion accidents may occur. Especially in mobile phone manufacturing, problems caused by static electricity hazards are prone to occur. Most companies will choose to use anti-static wrist straps or anti-static ankle straps to eliminate the hazards of static electricity.

To take preventive measures against electrostatic hazards in the process, we must first understand the principles of electrostatic hazards, be familiar with the factors that generate and dissipate static electricity during the development of hazards, as well as the types and hazards of electrostatic discharge, be able to identify the various stages of the formation of electrostatic hazards, and then be able to Use electrostatic measuring instruments to measure the causes of hazards, measure substances and environments in the process, master electrostatic physical quantities in the process, evaluate potential electrostatic hazards, conduct subsequent research and develop appropriate electrostatic hazard control methods, and continuously measure the effectiveness of electrostatic hazard protection measures. By comparison, it can effectively reduce the hidden dangers of static electricity and improve the safety of operations and personnel in the production process.

Communications manufacturing industry

Everyone knows that communication products have relatively high anti-static requirements in the production process, and there are many anti-static products used, such as: anti-static dust-free clothing, anti-static shoes and hats, anti-static wrist straps, etc. These protective products The use of it protects electronic products very well, not only communication products, but also many microelectronics, precision machinery, aerospace and other industries will use it.

Today we will focus on the performance characteristics of dust-free clothing. In addition to the anti-static performance of anti-static dust-free clothing, another outstanding feature of this fabric is its dust-free performance and dust-filtering performance. The dust-free performance of workshop dust-free clothing refers to The fabric itself does not produce dust, so employees wearing dust-free clean clothes will not bring dust into the workshop when entering the dust-free workshop and avoid contaminating products. Dust-free clothes have good dust removal performance, that is, there are fewer dust particles in the air. In many In this case, whether the product is qualified depends on the amount of attached dust or the impact of dust on product productivity. Therefore, the quality of dust-free clothing is closely related to the product qualification rate.

Microelectronics industry

In electronic production workshops, dust adsorbed on electronic components, especially in the production of very large-scale integrated circuits, will be greatly reduced. Operators in the production workshop wear clean work clothes. If the human body has static electricity, dust and dirt are easily absorbed. If the Dust and dirt brought to the operation site will affect product quality, affect product performance, and significantly reduce product yield. If the radius of the adsorbed dust particles is larger than the film, the product is likely to be damaged.

Therefore, it is necessary to establish an electrostatic protection system during the processing and packaging process. The clean factory can be decorated with anti-static building materials as a whole, and measures can be taken for the hardware so that all personnel entering and leaving the clean factory can wear anti-static clothing. etc. Packaging companies can formulate business standards or put forward specific requirements for anti-static according to relevant national standards and the actual situation of the company to coordinate with the normal operation of packaging production lines.

Since there are many types of anti-static equipment, choosing the right product mainly depends on the situation of the production line. The following are several types of anti-static equipment

1. Anti-static wrist strap: It is characterized by practical simplicity and very casual operation. It only needs to be worn on the hands or feet to guide the static electricity of the human body into the ground.

2. Anti-static grounding wire: It is mainly used to connect the workbench to the earth. Once static electricity is generated by friction on the workbench, it will be guided into the earth by the connecting wire.

3. Anti-static tester: mainly used to check whether the product has static electricity and whether the wrist strap is damaged

Medical and pharmaceutical industry

Sterile decontamination clothing is usually a protective product worn by workers in sterile rooms. It also includes anti-static wrist straps, anti-static ankle straps, etc. It is mainly used in industries with higher requirements such as medicine and food. It is different from ordinary The biggest difference between dust-free decontamination suits is the word "sterile". The use level of sterile decontamination suits is very high, and the requirements for use and management are also very strict. Staff must strictly follow the regulations and cannot ignore any small details. .

1. The sterile cleaning clothes in each work area should be marked and must not be worn together to prevent cross-contamination.

2. Sterile purification clothing should be cleaned and disinfected regularly according to normal methods.

3. The washing and drying of sterile purification clothing should be carried out in a clean room to avoid dust and insect contamination.

4. After washing and drying, the sterile clothes in the clean area and control area should be put into sterilization bags one by one for centralized sterilization. After sterilization, mark the status and indicate the sterilization date. Sterile work clothes should be used within 2 days. .

5. Employees who wear sterile purification clothing also have certain requirements for underwear. Although there are clean work clothes outside, the underwear will still emit dust. Therefore, the underwear fabric required by the staff should be polyester fiber to avoid dust.

food production industry

The most important link in the management of anti-static clothing is cleaning. The best choice for enterprises is to choose a professional cleaning company for cleaning. If there is oil on the recycled anti-static clothing, it should be carefully removed before cleaning. If there is oil on the electrical equipment , oil stains should be carefully removed before cleaning. Accessories should be checked for scratches, damage, buckles, etc. before cleaning. Defective ones should be repaired, replaced or scrapped. Cleaning, drying and bundling must be carried out in a clean room. The degree is higher than that in a clean room with work clothes. In order to remove water-soluble pollutants, after rinsing with water, use a distilled solvent for a final rinse to remove oil stains. Anti-static clothing with buckles should be cleaned in the buckled state. Stack them after drying In a clean room dedicated to washing and polyester, and put into a clean polyester bag or nylon bag. Upon request, double-layer packaging or vacuum plastic sealing can be used. The packaging material is preferably antistatic material. Due to folding The process is most likely to generate dust, so the folding process must be carried out in a high-level purified space. For example, the folding packaging of class 100 clean tooling should be carried out in a class 10 environment.

Aerospace industry

Anti-static wrist straps and anti-static ankle straps can solve the hazards of static electricity in the production process of the aerospace industry. Why does the current aerospace industry regard static electricity as a killer in the production process? Why do they regard electrostatic protection as a major industrial production project?
