Abstract: Substrate-supported circuitry is manufactured by forming circuitry on a high alumina dielectric substrate having a fluorescent character arising from the incorporation of both europium oxide plus yttrium (and/or lanthanum and/or gadolinium) oxide, with the latter oxide (s) acting as a dispersing agent. Testing the integrity of the circuitry is accomplished by irradiating the substrate with ultraviolet light and sensing the passage of any visible light through the circuitry that may occur in the presence of defects.
