NanoFoil® has many uses, and, sometimes, it has more than one function in an application. For instance, if tin coated NanoFoil® is used in an interface, it functions as a heat source AND as a source of solder. Indium-coated NanoFoil® has even more functions in a thermal interface application: it is a heat source, a source of solder, and a heat transfer medium. With a thermal conductivity of 25-30W/mK for the Ni/Al intermetallic and ~86W/mK for the indium coating, this is a highly conductive package – allowing proper heat transfer and minimal temperature excursion for the component.
