Multilayer co-fired ceramic compositions and ceramic-on-metal circuit
board
摘要:
A ceramic mixture of a crystallizable ZnO--MgO--B.sub.2 O.sub.3 --SiO.sub.2 glass mixed with a non-crystallizing lead-based glass and one or more oxide fillers forms a fired ceramic that has a TCE compatible with that of kovar. Green tapes made from the ceramic mixture aligned with a kovar support substrate when fired have excellent dielectric and low loss properties.
