Thin Film Coating Packaging for Device Having Meltable and Wetting Links

Abstract:

A method for creating a dielectric thin-film coating for devices having a fusible element is disclosed. The method comprises mixing insoluble and soluble polymers in solid form and exposing the mixture to heat to create a melt mixture. The melt mixture is then dissolved in a solvent to create a slurry which can then be deposited on the device as a thin-film coating to create an interior insulation layer or an external surface.
