The construction of high-level electronic dust-free workshop should focus on the following issues:

1. High-level electronic dust-free workshop has very strict requirements on the production environment.

In electronic factories, especially those in the microelectronics and optoelectronics industry, the production environment required by the process production of a large area of high cleanliness clean room is not only: building envelope, structure, air, water, gas, solvent and other raw materials, but also acoustic, optical, electrical, magnetic, vibration and other environments. The most important thing to build a high-level clean room in an electronic factory is to make the clean room built should be able to meet the strict requirements of the production process on the production environment, so that it can produce high-quality electronic products with high efficiency and high yield.

Second, the construction of high-level clean rooms in electronic factories costs very high investment.

The cost of investing in the construction of high-level cleanrooms is high. Generally speaking, level 4 (10) to level 5 (100) vertical one-way flow clean room, its indoor building envelope decoration (including wall, roof, ground, doors and Windows, etc.) and purification air conditioning system (including refrigeration and air conditioning, purification equipment, pipes and accessories) its initial construction investment is about 10 000 to 15 000 yuan per square meter; If coupled with pure water preparation equipment and system pipeline fittings, pure gas generation equipment and system pipeline fittings, waste water exhaust discharge equipment and system pipeline fittings; Pipeline fittings for fire fighting system equipment; The initial investment per unit area can be as high as 25 000 to 30 000 yuan per square meter for equipment pipeline fittings for power supply and distribution and automatic control systems as well as equipment pipeline fittings for centralized vacuum cleaning systems.

3. The operation and management costs of high-level clean rooms in electronic factories are very expensive.

Because the purification air supply volume of high-level clean room in electronic factory is large, the local exhaust air volume of process equipment is large, the fresh air volume is large, and the temperature and humidity requirements are strict, the cooling capacity, heat and humidification capacity of hot and humid air supply is also large, the energy consumption of air transmission and distribution is large, and the operation cost is very expensive. The operating cost of high-level clean rooms in electronics factories is as high as 5000 to 6000 yuan per square meter just to keep the indoor cleanliness, temperature and humidity.

Four, electronic factory high-level clean room adaptability, flexibility is very strong.

The development law of microelectronic integrated circuit tells us that every 2 to 3 years, the integration of its chip will be increased by 4 times, the feature size (line width) will be reduced by 30%, and the annual selling price will be reduced by 30%. The development of optoelectronics industry after microelectronics is even faster than that of microelectronics industry. In the design and construction of such a high-level clean room, the development and change of production technology should be taken into account, so that the clean room has good adaptability and flexibility.

Five, electronic factory high-level clean room safety and reliability is very good.

In order to produce high reliable, high quality, high yield of high-tech electronic products, in order to meet the strict requirements of the production process on the production environment, the design and construction of clean room must be safe and reliable in the first place, that is, to ensure the construction of the clean room of all production environment: Cleanliness, temperature and humidity, wind speed, pressure, noise, illumination and electrostatic vibration, electromagnetic and so on **** must meet the requirements of the production process. Ensure that the environmental parameters are reliable and stable. In addition, from the perspective of safety, that is, the safety of building structure bearing fire protection, explosion prevention and gas safety is very important.
