FIELD: chemistry.
SUBSTANCE: invention relates to a coated electrical assembly and methods of making a coated electrical assembly. Electric assembly has multilayer conformal coating on at least one surface of electrical assembly. Each layer of the multilayer coating can be obtained by plasma deposition of a precursor mixture containing (a) one or more organosilicon compounds, (b) optionally O2, N2O, NO2, H2, NH3, N2, SiF4 and/or hexafluoropropylene (HFP), and (c) optionally - He, Ar and/or Kr. First and lowest layer of the multilayer conformal coating is organic and is in contact with the surface of the electrical assembly.
EFFECT: invention enables to form coatings which would provide improved levels of protection from moisture.
