Abstract

The invention provides a dielectric ceramic assembly, a dielectric ceramic communication electronic component and a manufacturing method thereof. The dielectric ceramic assembly is applied to the dielectric ceramic communication electronic component and comprises at least two dielectric ceramic blocks; the at least two dielectric ceramic blocks are stacked; the outer surface of each dielectric ceramic block is coated with a metal conductive layer; viscous slurry layers are printed on the opposite faces, facing each other, of the metal conductive layers of every two adjacent dielectric ceramicblocks, each viscous slurry layer comprises metal powder, a glass phase and an organic additive, and the viscous slurry layers on the metal conductive layers of every two adjacent dielectric ceramic blocks are attached to each other; and the metal conductive layers of two adjacent dielectric ceramic blocks are welded with each other. The invention solves the technical problems that: in the prior art, when dielectric ceramic blocks are used for manufacturing filters, combiners and duplexers, silver plating layers are not resistant to welding heat, prone to disengagement from the surfaces of thedielectric blocks in the welding process, extremely prone to being corroded by soldering tin and more unfavorable for bearing welding heat many times.
