The Cleanroom Foam Swabs FS Series have the characteristics of high cleanliness, low ionic residue, good water absorption and softness, and are widely used in the following fields:
Electronics and Semiconductor

• Chip Manufacturing: In processes such as lithography and etching of chips, they are used to wipe off tiny particles and photoresist residues on the chip surface to prevent impurities from affecting the performance and yield of chips.
• Printed Circuit Board Production: They can be used to clean the surface of printed circuit boards, removing flux residues and dust generated during the soldering process to ensure the electrical performance and reliability of the circuit boards.

Precision Instrument Manufacturing

• Optical Instruments: For optical instruments such as microscopes and telescopes, they can be used to wipe optical lenses and objectives, effectively removing fingerprints, oil stains, and dust without scratching the lens surface and ensuring the imaging quality of optical instruments.
• Precision Components in Aerospace: For precision components such as aero-engine blades and avionic equipment, during the production and assembly processes, these swabs are used for cleaning and wiping to ensure the cleanliness of the component surfaces and meet the strict requirements for component quality and reliability in the aerospace field.

Medical and Pharmaceutical

• Medical Device Production: During the production of syringes, infusion sets, implantable medical devices and other medical devices, they are used to clean the surfaces of the devices to remove impurities that may remain during the production process and ensure the sterility and safety of medical devices.
• Drug Research and Development and Production: In drug research and development laboratories and production workshops, they can be used to wipe experimental instruments and drug packaging bottles to prevent impurities from being mixed into drugs and ensure that the quality of drugs meets the standards.

Liquid Crystal Display (LCD) and Organic Light-Emitting Diode (OLED) Manufacturing

• Screen Production: During the production of LCD and OLED screens, it is necessary to clean glass substrates and liquid crystal panels. The Cleanroom Foam Swabs FS Series can effectively remove stains, dust and particles on the surface to ensure the display effect and quality of the screens.
• Backlight Module Cleaning: For optical materials such as reflectors and diffusers in the backlight module, using these swabs for cleaning can avoid light scattering and unevenness caused by impurities and improve the performance of the backlight module.

Laboratory Research

Biological Experiments: In biological experiments such as cell culture and DNA extraction, they are used to clean experimental equipment and workbenches to prevent microbial contamination and impurity interference with experimental results.

Chemical Experiments: In chemical experiments, they can be used to wipe experimental vessels such as test tubes, beakers and volumetric flasks to remove residual chemical reagents and ensure the accuracy of experimental results.
