Discussion on the solution of purification workshop of optical microelectronics purification engineering
Release time:2019-11-13 source:
Optical microelectronics purification project is defined as a special designed confined space, which can remove the dust particles, harmful air, bacteria and other pollutants in the air within a certain space, and control the indoor temperature and humidity, cleanliness, indoor pressure, air velocity and air distribution, noise, vibration, lighting and static electricity within a certain demand range.
The optical microelectronics purification project, also known as dust-free room or clean room, has become an indispensable and important facility for semiconductor, precision manufacturing, liquid crystal manufacturing, optical manufacturing, circuit board manufacturing, biochemistry, medicine, food manufacturing and other industries. In recent years, due to the development of technological innovation, the demand for high precision and miniaturization of products is more urgent. For example, the research and manufacture of VLSI has become an important item in the development of science and technology all over the world.
Optical microelectronic purification engineering generally includes:
1. Clean production area
2. Clean auxiliary room (including personnel purification room, material purification room and some living rooms, etc.)
3. Management area (including office, duty, management and rest)
4. Equipment area (including purification air conditioning system application, electrical room, high-purity water and high-purity air room, cold and hot equipment room)
Materials for clean workshop
1. The wall and top plate of purification plant are generally made of 50mm thick sandwich color steel plate, which is characterized by beautiful appearance and strong rigidity. Arc wall corner, door, window frame, etc. are generally made of special aluminum oxide.
2. The floor can be epoxy self flowing floor or high-grade wear-resistant plastic floor. If there is anti-static requirement, the anti-static type can be selected.
3. The air supply and return pipes are made of hot-dip zinc plate and pasted with flame-retardant pf foam plastic plate with good purification and heat preservation effect.
4. The high-efficiency air supply outlet is made of stainless steel frame, which is beautiful and clean. The perforated mesh plate is made of baking varnish aluminum plate, which is rust free and dust free, so it should be cleaned.
Optical microelectronic purification engineering solutions:
Combined air handling unit + chiller + efficient air supply outlet.
The combined air treatment unit contains various functional sections, such as mixing section, primary filter section, surface cooling section, secondary return air section (or intermediate section), heating section, humidification section, medium efficiency filter section, fan section, etc. The cold source is provided by the water chiller.
Advantage:
A. the air treatment effect is good, because the air is subject to centralized treatment, and the degree of pollution is relatively low in the process of air supply. The temperature and humidity of the air supply are controlled accurately;
B. It is applicable to plants with centralized cooling source or large plants;
C. the air conditioning cold and heat sources can be shared or independent with the general air conditioning system of the plant;
D. low maintenance frequency;
E. low noise in the workshop.
