Cleaning, refrigeration industry and people's production and life practice is closely related. With the development of society and the progress of Science and technology, the rapid development of electronic information industry, people put forward higher requirements for electronic related industries: precision, stability, lightweight, reliability, etc. , at the same time need to provide good cleaning and cooling conditions. Electronic components, precision components and other electronic information products, of course, they also need to“Bathe”“Cool”, and on the detergent and refrigerant put forward higher requirements, such as high energy efficiency, safety, low toxicity, non-pollution, such as hydrofluoroether (HFE) series of fluorinated liquid can take this task, the research of HFE fluorinated liquid has become a hot spot of the society, Enterprises and academia.
1. The properties of fluorinated liquid
HFE fluoridation solution is a kind of fluorine solution of hydrofluoroether. It is used as additive for lithium battery, solvent for lubricating oil, reaction solvent, refrigerant, cleaning agent and so on.
HFE fluoridation fluid can be used to clean and refrigerate electronic and information products, such as electronic components and precision components. Besides being safe, environment-friendly, low global-warming potential (GWP) , HFE fluoridation fluid also has excellent performance, for example: Safety: non-toxic, non-flammable, non-flashpoint;
Performance: low surface tension, low viscosity; high density; moderate solubility; excellent electrical insulation performance; excellent thermal conductivity; non-flammable, no flash point; thermal stability, chemical stability.
n the field of electronic components, precision components and other electronic information products, the"Cleaning general" in HFE fluoridation solution D 3, "Refrigeration General" HFE fluoridation solution D 4
2. “Master of cleaning”-HFE fluoridation solution D 3
HFE fluoride D3 can be used to clean electronic components, precision components and other electronic information products. It can be used as a single solvent or combined with hydrocarbon cleaning agent. As a single solvent for cleaning, with excellent drying performance, excellent material compatibility, non-flammable and so on.
Examples of specific applications: CCD, CMOS sensors and other electronic equipment dust removal (remove particles) ; semiconductor production equipment parts, cavity cleaning; particle erasure cleaning; printing parts after the film cleaning. Combined with hydrocarbon cleaning agent, the co-solution system realizes the non-burning of the cleaning device, so the risk of fire can be controlled, there is no residue after cleaning, the quality is higher, the temperature is lower when drying, the heat shock to the workpiece is smaller; Excellent material compatibility; low surface tension, permeable to clean and dry the fine structure of the workpiece. Examples of specific applications: liquid crystal modules, panels cleaning, precision processing parts of silicone oil cleaning, drying, cleaning aircraft parts of the cutting oil.
HFE fluorination liquid D 4
In cooling, heat exchange and temperature control applications, in the semiconductor line width increasingly refined process, for thermal conduction and temperature control of the refrigerant requirements are higher and more diverse. HFE fluorinated liquid D 4 can be used as a“Refrigeration general” in the field of electronic information products such as electronic components, precision components and so on. It can be used as refrigerant of semiconductor production equipment, with excellent electrical characteristics, wide temperature range, no sediment, non-combustibility and so on.
Examples of specific applications: dry etching device; photolithography; ion ejector; probe; IC Tester and so on.
Juhua joint-stock technology center after more than ten years of technical research, developed a series of superior performance of electronic fluoride liquid products-HFE Series D products (D 3, D 4, etc.) . It is widely used in foaming agent, high-end electronic fluid in electronics industry, cleaning of various precision collection, dehydration and drying, electronic component side leakage liquid or air tightness test liquid, solvent, etc. .
