The recommendations for the use of cleanroom wipers mainly include the following aspects
Choose a suitable dust-free cloth: Choose the appropriate type of dust-free cloth according to the cleaning object. Ordinary polyester dust-free cloth can be used for general equipment cleaning; for precision instruments and chips, it is recommended to use microfiber dust-free cloth to better protect sensitive surfaces; for specific processes such as mobile phone covers and camera covers, it is recommended to use a reel-type dust-free cloth.
Preparation before use: Before using the dust-free cloth, make sure to unpack the inner packaging bag in a clean environment, and clean the packaging bag before unpacking, especially the opening to keep it clean. Before use, remove the surface dust through the air shower window, and wear dust-free gloves and masks when unpacking and using.
Wiping method: Avoid edge contact: The four sides of the dust-free cloth are generally sealed with laser or ultrasonic waves. When wiping, avoid direct contact with the surface of the object with the edge to avoid damage.
One-way wiping: One-way moving wiping can reduce secondary pollution and improve cleaning efficiency. Full contact: Ensure that the dust-free cloth fibers are in full contact with the surface to achieve the best cleaning effect.
Use with solvent: You can use cleaning solvents (such as IPA or alcohol) for wiping, but make sure that the solvent is compatible with the surface to be cleaned to avoid chemical reactions or corrosion.
Precautions:
Force control: When cleaning sensitive surfaces, the force should be moderate to avoid damaging the surface of the object or the edge of the dust-free cloth.
Avoid rubbing and folding: Keep the dust-free cloth flat during operation, and do not rub or fold it.
Regular replacement: According to the regulations of the clean room, replace the wiping cloth in time to ensure the continued cleaning effect.
