After the electronic clean workshop is built, dust particles need to be detected to ensure that it meets the specified cleanliness standards. So how to detect whether dust particles reach the standard after building an electronic clean workshop? Today Xiaobian will introduce several detection methods for you!

1, electrostatic sedimentation method: a certain number of glass or metal plate is placed in the workshop, after a certain time, with a microscope to observe the number and size of the dust particles, so as to judge the cleanliness.

2, aerosol counter method: The aerosol counter is used to sample and test the air in the workshop, and the cleanliness is judged by calculating the number and size of dust particles in the air.

3. Cleanliness tester method: The cleanliness tester is used to sample and test the air in the workshop, and the cleanliness is judged by calculating the number and size of dust particles in the air.

4, cleanliness detection board method: the cleanliness detection board is placed in the workshop, after a certain period of time, with a microscope to observe the number and size of dust particles, so as to judge the cleanliness.

It should be noted that different cleanliness standards correspond to different amounts and sizes of dust particles. Therefore, it is necessary to know the required cleanliness standards before testing.
