Introduction产品简介
3M氟化液FC-43是无色透明全氟化学品,具有良好的化学惰性、电气绝缘性能、热传导性、不燃、材料材料相容性好,对于一些敏感元器件没有损伤,无毒而且没有残留等优点而广泛应用于电子厂作为电性能及可靠性测试液体。其沸点可以达到174?C,所以FC-43可以用于高温老化试验、环境应力筛选和气相焊的导热液体。其还符合美国军标Military Speci?cation 883,可以用于测漏及热冲击试验的高温导热液体。因为其产品的惰性,还可以用于反应媒介。
3M Fluorinert Electronic Liquid FC-43 is a clear, colorless, fully-?uorinated liquid. Like other Fluorinert electronic liquids, Fluorinert liquid FC-43 is thermally and chemically stable, compatible with sensitive materials, non?ammable, practically non-toxic and leaves essentially no residue upon evaporation. This unique combination of properties makes Fluorinert liquid FC-43 ideal for many electronics applications,including many electronic quality and reliability tests. With a boiling point of 174?C, Fluorinert liquid FC-43 is ideal for use in liquid burn-in testing, environmental stress screening and some vapor phase soldering processes. It conforms to Military Speci?cation 883 as an indicator ?uid in gross leak testing and as the hot ?uid for thermal shock testing. The wide liquid range of Fluorinert liquid FC-43 makes it an ideal heat transfer ?uid. Its inert nature allows for use as a reaction medium.
