        3M氟化液FC-77,已被FC-770替代

        Introduction產品簡介

        3M氟化液FC-77是一種熱穩定,全氟液體主要作為工業的和傳導液。由于FC-77的化學惰性,所以可以用于單相或者二相的冷卻液,用于超級計算機系統和軍用的敏感電子元器件。因為其非常高的絕緣性,其可以用于高壓變壓器和高功率電子元器件的冷卻。在半導體行業,FC-77主要用于蝕刻設備、離子注入設備,化學氣相沉積(CVD)的恒溫冷卻液。由于FC-77的傾點非常低,所以可以用于冷熱沖擊試驗及其他各種測試。


        3M Fluorinert Electronic Liquid FC-77 is a thermally stable, fully-?uorinated liquid that has long been used as a heat transfer ?uid in a variety of industries. The inertness of Fluorinert liquid FC-77 permits its use as a direct contact single and two-phase coolant in supercomputers and sensitive military electronics. Its high dielectric strength and electrical resistivity are ideal for applications in high voltage transformers and power electronics. In the semiconductor manufacturing industry, its wide liquid range makes Fluorinert liquid FC-77 ideal for cooling ion implanters, dry etchers and CVD machines. Its low pour point also permits its use in thermal shock and test equipment.
