How big is the impact of not wearing anti-static and dust-free clothing
With the development of science and technology, high-tech industries such as electronics, aviation, medicine, and biology are paying more and more attention to the quality of products. In order to develop high-end top products, the working environment needs to be dust-free, and their staff will also wear Wear anti-static and dust-free clothing.
Dust, mainly from people, can account for about 90% in a clean room. Secondly, the material, style, cleaning method, and activity of anti-static clean clothes will affect the amount of dust.
Material: Cotton garments generate the most dust, followed by cotton, Zhenliang, antistatic pure polyester, and nylon.
Style: The anti-static gown generates the largest amount of dust, the second is the anti-static split suit, and the anti-static coverall is the least.
Activity: When the human body is in motion, the amount of dust generated is 3-7 times that of the static state, so avoid running in a clean room.
Cleaning: Use a special solvent to clean the anti-static dust-free clothing, and the amount of dust can be controlled at about 1/5 of that of ordinary water.
Dust-free does not mean that there is no dust at all, but the amount of fine dust larger than 0.5 microns in size is controlled in a very low range. In the production of electronic components, these fine dusts have a great influence on the yield.
