The Function and Application Scope of Fluorinated Liquids as Cleaning Agents
Core role
- Highly effective stain and grease removal : Low surface tension and strong solvency enable rapid removal of flux residues, oil contaminants, and ionic pollutants from workpiece surfaces, making it ideal for micron‑scale gap cleaning of precision components.
- No corrosion, no residue. : Highly chemically inert, it does not react with most metals, plastics, or polymers, posing no risk of substrate damage; it is readily volatile and leaves no residue, thereby preventing short circuits or optical defects caused by water marks.
- Environmentally friendly and safe alternative : It serves as a replacement for traditional solvents such as CFC‑113 and trichloroethylene, with an ODP of 0 and a low GWP, meeting environmental regulatory requirements. It is non‑flammable and non‑explosive, ensuring safer use.
- Dehydration and Drying Assistance : It is immiscible with water and has a specific gravity much greater than that of water, enabling it to rapidly displace moisture from the surface of workpieces and from micropores, thereby achieving non‑destructive dehydration and drying.
Main application areas
- Semiconductors and Electronic Manufacturing : Precision cleaning of wafers, PCBs, connectors, and chip packaging components to remove nanoscale contaminants, ensuring the performance and stability of electronic components.
- Optical industry : Cleaning and drying of optical lenses, camera lenses, and LCD/OLED panels—leaving no residue and causing no corrosion, thereby preventing degradation of optical performance.
- Medical equipment sector : Cleaning of precision medical devices and sensor components, with low volatility and zero pollution, meeting the cleanliness requirements of the medical industry.
- Industrial precision components : Oil‑contaminant cleaning of precision bearings, gears, cutting tools, and other mechanical components, compliant with high‑cleanliness industrial process standards.
- Aerospace components : Precision component cleaning for satellites and aerospace equipment—non-corrosive, residue-free, ensuring long-term reliability.
