{tab Applications|blue}

Listed below are key applications for FC-770. Documents specific to the application are listed to the right.

Heat Transfer Fluids

The wide liquid range of Fluorinert liquid FC-770 (-127°C to 95°C) makes it ideal for use in automated test equipment (ATE) and other semiconductor process equipment. Its high dielectric strength means it will not damage electronic equipment or semiconductor wafers, chips or packages in the event of a leak or other failure.

In addition, FC-770 liquid is chemically stable, nonflammable and practically non-toxic.

Testing Fluids

The low pour point of FC-770 liquid (-127°C) permits its use in thermal shock testing equipment. Conforming to Military Standard 883-1011, the liquid is an ideal fluid for the cold phase of the test because it has precise temperature control, rapid heat transfer due to its high thermal conductivity, excellent material compatibility and no post-test clean-up.
