Is the clean room 100% dust-free?
With the development of science and technology, more and more high-precision electronic products are used in aerospace, biological research, semiconductor, medical and other industries. The production of these high-precision products needs to be produced in a dust-free and clean environment, that is, in a clean room.
So, is the so-called clean room 100% dust-free?
In fact, dust-free does not mean that there is no dust at all, but that the dust is controlled to a very small amount. By controlling the number of fine dust particles smaller than 0.5 microns per cubic meter to less than 3,500 particles, it reaches Level A of the international dust-free standard.
Clean room, also known as clean room or dust-free workshop. Dust-free clean rooms can eliminate particles, bacteria and other pollutants in the air within a certain space, and control the indoor temperature, cleanliness, indoor pressure, air flow speed and air flow distribution, noise, vibration, lighting, and static electricity to a certain level. within the scope of requirements.
Therefore, the clean room is not 100% dust-free.
