Reasons and requirements for the construction of electronic dustless clean rooms in the electronics industry

May 10, 2018

In the electronic industry, clean room is mainly used to produce precision electronic products. It is the removal of pollutants such as particles, harmful air and bacteria in the air of a certain space, and the room temperature, cleanliness, pressure, air velocity and air distribution, noise vibration and lighting, static control. A specially designed room within a specific requirement.

 

That is to say, no matter how the external air conditions change, the clean room can maintain the original requirements of cleanliness, temperature, humidity and pressure. Precision electronic products are basically produced in a clean room above 100 level.

 

The high precision electronic components are particularly high in the environment requirements. The quality of the produced electronic components is often related to the suspended dust particles in the air. So in the electronic production workshop, it is often built to be dust-free and clean rooms, ensuring the number of suspended particles in the air to ensure the high electronic components. Quality, at the same time, make the electronic production environment cleaner.

 

Because there are many kinds of production technology in the electronics industry, the requirements for cleanliness grade of clean room are also different; the requirements for particle size control are different; the requirements for temperature and humidity control are relatively high; and the gradient level required by the positive pressure value changes from high to low with the change of cleanliness.

 

There are many kinds of poisonous and harmful gases produced in the production process of the electronic industry, and the quantity is large, so the air discharge volume and the new air quantity are also great. The noise level in the clean room of the dustless clean room should not be more than 65dB (A); the static pressure difference between the room and the outdoor should not be less than 10Pa, and the static pressure difference between the clean area of different air cleanliness and the unclean area should not be less than 5Pa.

 

The vertical cleaning room in the clean room of the electronic industry is not less than 60%, and the horizontal one-way flow cleaning room should not be less than 40%. Otherwise, it is a local one-way flow. At the same time, it is guaranteed that the fresh air volume per hour for a dustless clean room is not less than 40m.http://www.wxrfcleanroom.com/
