electronic dust purification workshop

Adapt to the industry:Electronics, microelectronics, semiconductors, precision manufacturing, liquid crystal manufacturing, optical manufacturing, circuit board manufacturing, etc. Recommended level: Level 1 - 100,000
(1) The role of dust-free purification workshop
The main function of the electronic clean room is to control the cleanliness and temperature and humidity of the atmosphere contacted by products (such as silicon chips), so that the products can be produced and manufactured in a good environment. This space is called dust-free. workshop. According to international practice, the clean room purification level is mainly based on the number of particles per cubic meter of air whose particle diameter is larger than the standard. That is to say, the so-called dust-free is not 100% without a little dust, but is controlled in a very small unit. Of course, the dust-compliant particles in this standard are already very small compared to our common dust, but for optical construction, even a little bit of dust can have a very large negative impact, so in the production of optical construction products. No dust is an inevitable requirement.
 

(II) Control project of dust-free purification workshop
1. It can remove the dust particles floating in the air.
2, can prevent the generation of dust particles.
3. Control of temperature and humidity.
4. Adjustment of pressure.
5. Exclusion of harmful gases.
6. The airtightness of the structure and the compartment.
7, the prevention of static electricity.
8, electromagnetic interference prevention.
9. Consideration of safety factors.
10. Energy saving considerations.
(III) Advantages of constant standard
Optical microelectronics purification engineering, also known as clean room or clean room, is now an indispensable and important facility for semiconductor, precision manufacturing, liquid crystal manufacturing, optical manufacturing, circuit board manufacturing, and biochemistry, pharmaceutical, food manufacturing and other industries. In recent years, due to the innovation and development of technology, the demand for high precision and miniaturization of products has become more urgent. For example, the research and manufacture of ultra-large integrated circuits has become a project that countries in the world attach great importance to in the development of science and technology. Our company's design concept and construction technology are in a leading position in the industry. Hengbiao Company has a professional dust-free clean engineering designer and a field management construction team with many years of experience.
 

(four), the importance of dust-free purification workshop
The cleanliness of the dust-free purification workshop is often affected by the airflow. In other words, the movement and diffusion of dust generated by people, machine compartments, building structures, etc. are governed by the airflow. The aseptic purification workshop uses HEPA and ULPA to filter the air. The dust collection rate is as high as 99.97~99.99995%, so the air filtered through this filter can be said to be very clean. However, in addition to people in the dust-free purification workshop, there are still dust sources such as organic devices. Once the dust generated is spread, the clean space cannot be maintained. Therefore, the dust generated by the airflow must be quickly discharged to the outside.
(5), electronic dust-free purification workshop installation materials
1. The wall and top plate of the purification plant are generally made of 50mm thick sandwich color steel plate, which is characterized by beautiful appearance and strong rigidity. Arc wall corners, doors, window frames, etc. are generally made of special alumina profiles.
2. The ground can be epoxy self-flowing floor or high-grade wear-resistant plastic floor. If there is anti-static requirement, anti-static type can be used.
3. The return air duct is made of hot-dip zinc plate, and the flame-retardant PF foam plastic plate with good purification effect is attached.
4. Efficient air supply port with stainless steel frame, beautiful and clean, punched stencil with painted aluminum plate, no rust and no dust, should be clean.
