    摘要: Improved copper conductor inks useful in fabricating multilevel circuits are provided. The inks comprise copper powder, a devitrifying glass frit which does not begin to flow until the furnace temperature is above about 700.degree. C., and a suitable organic vehicle. Devitrifying glass frits with these properties include a zinc-calcium-aluminum-silicate glass frit, a zinc-magnesium-barium-aluminum-silicate glass frit, a zinc-magnesium-barium-aluminum-zirconium-phosphosilicate glass frit and mixtures thereof. The inks are advantageous in that they form copper conductor layers having excellent properties without the inclusion of traditional flux materials such as bismuth oxide.

    摘要: Improved thick-film overglaze inks useful in constructing multilayer integrated circuits on circuit boards, particularly porcelain-coated metal circuit boards, are provided. The subject inks comprise: a glass consisting of lead oxide, a modifier component consisting of the oxides of cadmium, zinc, barium and antimony and a glass-forming component consisting of aluminum oxide, boron trioxide and silicon dioxide; a suitable organic vehicle and, if desired, a colorant oxide.

    摘要: A novel devitrifying glass comprising, in weight percent, from 5-15% of zinc oxide, from 10-18% of magnesium oxide; from 15-20% of calcium oxide; from 6-14% of barium oxide; from 15-20% of aluminum oxide and from 30-40% of silicon dioxide. The glasses are thermally matched to alumina substrates. The glasses form overglaze thick film inks when admixed with an organic vehicle that are useful as protective coatings for alumina substrates and multilayer printed circuits.
