ABSTRACT:
A method for bonding a first ceramic element and a second ceramic element utilizes a silver powder paste composed of silver particles dispersed in a volatile vehicle. A film of the paste is applied and dried onto a faying surface of each element. The elements are assembled with the films in contact and heated to sinter the silver particles into an integral silver layer that is bonded to the faying surfaces, thereby bonding the elements together. The method is particularly well suited to manufacturing a stripline filter, wherein the sintered layer not only bonds the ceramic elements, but also forms a metallic feature, such as a resonator, of the filter.
