Hermetic chip on board

A low permeability laminate film comprising:

• one or more low moisture permeability homogeneous polymer films with a total thickness between 0.5 and ten mils without glass or ceramic fillers and with a moisture permeability measured at 37° C. and 100% RH of less than 0.23 gm mm/m2 day equivalent to a standard leak rate of 2.6 E-05 atm·cc·mm/in2·sec of air, the polymer film including one of thermotropic liquid crystal polymer, polychlorotrifluoroethylene, polytetrafluorethylene, fluorinated ethylene propylene, and perfluoro alkoxy alkane;
• and
• a nanolaminate including alternate combinations of nanolaminate material that is selected from the group consisting of alumina, titanium dioxide, zirconium oxide, beryllium oxide, hafnium oxide, titanium oxide, silicon nitride, tantalum nitride, silica, parylene F, parylene AF-4, parylene and PTFE (polytetrafluoroethylene),
• wherein a resulting coated nanolaminate film has a moisture permeability that may be less than an equivalent standard leak rate per square inch of 3.0 E-08 atm·cc/in2·sec of air.
