Abstract
Abstract A radio frequency intelligent communications device is fabricated from a substrate formed to have conductive lines, at least a portion of which comprise an antenna. An integrated circuit chip and a battery are conductively bonded to the conductive lines on the substrate. A visible spectrum colored liquid resin and a visible spectrum substantially colorless liquid hardener are combined into an epoxy mixture. The liquid hardener has a fluorescent material received therein. Radiation is impinged onto the epoxy mixture effective to cause the fluorescent material to fluoresce. From the fluorescing fluorescent material, degree of homogeneity in the epoxy mixture can be determined. Upon achieving desired homogeneity, the substrate with chip and battery are encapsulated in the epoxy mixture, with the epoxy mixture being cured. The invention also has applicability to epoxy systems and other liquid mixtures having at least to liquid components. The invention also comprises providing first and second liquids where one of said liquids has an invisible component therein. The first and second liquids are combined together into a mixture. The invisible component remains invisible in the mixture upon the combining. After the combining, the component is rendered visible. Degree of homogeneity in the mixture is determined while the component has been rendered visible. After the determining, the component is rendered invisible.
