    摘要: An improved ink composition suitable for the formation of thick film resistor inks which can be terminated directly to copper foil conductors. The subject compositions comprise an epoxy resin, conductive carbon particles, a suitable solvent and particulate alumina, wherein the alumina is present in an amount at least equal to the resin content on a weight basis.

    摘要: An improved copper via-fill ink for forming post-ups in a thick dielectric layer separating two patterned layers of copper conductor in a multilayer circuit assembly is provided. The via-fill ink comprises copper powder, a suitable organic vehicle and a glass frit consisting of a devitrifying glass and a vitreous glass. The devitrifying glass is a zinc-magnesium-barium-aluminum-zirconium-phosphosilicate glass and the vitreous glass is a barium-calcium-borosilicate glass.
