Non-ruthenium embedded resistor paste capable of being co-fired at low temperature and preparation method of non-ruthenium embedded resistor paste
The invention belongs to the technical field of electronic materials, and particularly relates to non-ruthenium embedded resistance paste capable of being co-fired at low temperature and a preparation method of the non-ruthenium embedded resistance paste. According to the invention, non-ruthenium series La0. 5Sr0. 5Co0. 96Ni0. 04O3 or La0. 5Sr0. 5Co0. 94Nb0. 06O3 ceramic is used as a conductive phase, so that the material cost is reduced, and the defect that a traditional metal material is easy to oxidize at a high temperature is avoided; bi2O3-B2O3-SiO2-ZnO and Li2O-Bi2O3-B2O3-SiO2 + TiO2, which are chemically compatible and adaptive to the conductive phase, are combined as an inorganic binding phase, and an organic carrier is supplemented to form the non-ruthenium resistance paste. The embedded resistor prepared by adopting the resistor paste can be matched and co-fired with a multilayer dielectric ceramic green tape (the dielectric constant is less than or equal to 8) at 925 DEG C, the matching property after sintering is relatively good, obvious warping and layering are avoided, the process adaptability is good, and the embedded integration of the resistor in a multilayer ceramic circuit substrate can be realized through an LTCC (Low Temperature Co-Fired Ceramic) technology. The method has the characteristics of low cost and high performance, and provides a foundation for realizing the embedding integration of the resistor element in the multilayer ceramic substrate.
