Semiconductor production industry

In the semiconductor production workshop, due to dust adsorption on the chip, especially the output of VLSI will be greatly reduced. All operators in the production workshop should 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 job site, it will directly affect the product quality, increase the defective rate, and greatly reduce the yield. If the radius of the adsorbed dust particles is greater than the width of the line, and When there is the thickness of the film, 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 on static electricity. In order to ensure the normal operation of the production line, Carry out the overall decoration of anti-static building materials for its clean workshop, and take hardware measures such as equipping all personnel entering and leaving the clean workshop with anti-static clothing. Packaging companies can formulate enterprise standards or put forward specific requirements for anti-static according to relevant national standards and the actual situation of the enterprise , in order 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 performance, another outstanding feature of this fabric is dust-free and dust-filtering performance, so that employees wearing dust-free clean clothing will not be dusted when entering the clean room. Bringing it into the workshop, you only need to wear an anti-static wrist strap during production to avoid damage to the product caused by static electricity; the good dust filtering performance of the dust-free clothing means that the human body emits fewer dust particles into the air. In many cases, the product Whether it is qualified 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, eliminate sweat and odor, reduce the wearer's discomfort.

Mobile phone manufacturing industry

In most industrial processes, static electricity will accumulate, causing products to be scrapped and people to be injured. Even in the process of loading, unloading and transportation, fire and explosion accidents will occur. Especially in the manufacture of mobile phones, 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, one must first understand the principle of electrostatic hazards, be familiar with the factors that generate and dissipate static electricity in the process of hazard development, and the types and hazards of electrostatic discharge, be able to identify the various stages of electrostatic hazard formation, and then be able to Use electrostatic measuring instruments to measure the causes of hazards, measure substances and environments in the process, grasp the physical quantities of static electricity in the process, evaluate potential electrostatic hazards, follow-up research and develop appropriate electrostatic hazard control methods, and continuously measure the effect of electrostatic hazard protection measures Compared with it, it can effectively reduce the hidden dangers of electrostatic hazards and improve the operation and personnel safety in the production process.

Communication manufacturing industry

Everyone knows that communication products have relatively high anti-static requirements in the production process, and there are many anti-static products that will be 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.

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 that employees wearing dust-free clean clothes will not bring dust into the workshop when entering the clean room, so as to avoid polluting products. Dust-free clothes have good dust removal performance, that is, there are few dust particles in the air. In many Under normal circumstances, whether the product is qualified depends on the amount of dust attached 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 the electronic production workshop, the dust adsorbed on the electronic components, especially the production of VLSI will be greatly reduced. The operators in the production workshop wear clean work clothes. If the human body has static electricity, the dust and dirt are easily absorbed. 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 in the process of processing and packaging. The overall decoration of anti-static building materials can be carried out for its clean workshop, and measures should be taken for five metal parts so that all personnel entering and leaving the clean workshop can wear anti-static clothing etc. Packaging enterprises can formulate business standards or put forward specific requirements for anti-static according to the relevant national standards and the actual situation of the enterprise, in order to cooperate with the normal operation of the packaging production line.

Due to the wide variety 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 practicality and simplicity, and a very casual operation method. It only needs to be worn on the hand or foot 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 with 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 staff in the sterile room. It also includes anti-static wrist straps, anti-static ankle straps, etc. It is mainly used in industries with high requirements such as medicine and food. It is different from ordinary The biggest difference between dust-free decontamination clothing is the word "sterile". The use level of sterile decontamination clothing is very high, and the requirements for use and management are also very strict. The 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 not mixed to prevent cross-contamination.

2. Sterile cleansing clothes are regularly cleaned and disinfected according to normal methods.

3. The washing and drying of sterile clean clothes should be carried out in a clean room to avoid dust and pest pollution.

4. After washing and drying, the sterile clothes in the clean area and the control area should be put into sterilization bags one by one for centralized sterilization. After sterilization, the status should be marked and the date of sterilization should be marked. The 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 still emits dust, so the underwear fabric worn 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. Before cleaning, check whether the accessories are scratched, damaged, buckled, etc., and repair, replace or scrap the defective ones. Cleaning, drying and bundling must be carried out in a clean room. The degree is higher than that of the clean room with work clothes. In order to remove water-soluble pollutants, after rinsing with water, perform a final rinse with distilled solvent to remove oil stains. The anti-static clothing with buckles should be cleaned in the buckled state. After drying, stack them In a clean room dedicated to washing and polyester, and put into a clean polyester bag or nylon bag. According to requirements, it can be double-packed or vacuum plastic sealed. The packaging material is preferably an 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 purification 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 electrostatic hazards in the production process of the aerospace industry. Why do they regard static electricity as a killer in the production process of the aerospace industry now? Why do they regard static electricity protection as a large-scale industrial production project The main hazards of static electricity in the medium are summarized as follows:

(1) Cause electronic equipment failure or misoperation, resulting in electromagnetic interference.

(2) The failure of integrated circuits and precision electronic components may promote the aging of components and reduce the yield of production.

(3) Electric shock caused by high-voltage electrostatic discharge endangers personal safety.
