The clean room used for the production of precision electronic products is also called dust-free workshop. It refers a room is specially designed to the removal of particulates, harmful air, bacteria and other pollutants in the air within a certain space, and controls the indoor temperature, cleanliness, indoor pressure, airflow velocity and airflow distribution, noise, vibration and illumination, and static electricity within a certain range of demand. In other words, no matter how the external air conditions change, the indoor environment can maintain the original requirements of cleanliness, temperature, humidity and pressure.Precision electronic products are mainly produced in class 100 or above dust-free workshops (including class 100 dust-free workshops).
The dust-free workshop is mainly used in industries such as electronics, semiconductors, food, printing and packaging. With the development of society, more and more industries also need clean room purification projects. The needs of the production process are closely related to the production equipment and production environment.
In the electronic production workshop, as people move in and out, they often bring in a lot of dust particles, while high-precision electronic components have extremely high environmental requirements. The quality of the electronic components produced is often related to the suspended dust particles in the air, so it is often built as a clean room in the electronics production workshop. The number of suspended particles in the air is guaranteed to ensure the high quality of electronic components. The negative ion purification air system in the clean room equipment can reduce the concentration of suspended particulates in the air and make the electronic production environment more clean.
