Application Guide
Listed below are key applications for FC-43. Documents specific to the application are listed to the right.
Heat Transfer Fluids
Its wide liquid range (-50°C to 174°C) and non-conductivity make Fluorinert liquid FC-43 well-suited to a variety of heat transfer applications - especially in the electronics industry. In addition, it is thermally and chemically stable, compatible with sensitive materials, nonflammable and practically non-toxic. It's an ideal thermal management fluid for applications such as etchers, ion implanters, testers and more.
Testing Fluids
With a boiling point of 174°C, Fluorinert liquid FC-43 is ideal for use in liquid burn-in testing, environmental stress screening, electronic quality and reliability tests, gross leak testing and as the hot fluid for thermal shock testing. The liquid conforms to all applicable military specifications regarding hermetic seal/gross leak testing and thermal shock testing.
Vapor Phase Reflow Soldering Fluids
Fluorinert liquid FC-43 is typically used with solders like 70 Sn/18 Pb/12 In, 100 In, 58 Sn/42 In, or 58 Bi/42 Sn. FC-43 liquid can be used in a variety of vapor phase reflow soldering applications, including:
BGA attach
Conventional through-hole or SMT circuit assembly reflow
Fluxless fusion of circuit board electroplating
Assembly of metal components having complex geometric shapes
