摘要
The present invention is directed to a method to produce a co-fired, metallized high dielectric constant ceramic core comprising: providing a precursor green laminate comprising at least one layer of core tape wherein said core tape has a dielectric constant of at least 20; and firing said precursor green laminate. The method is further directed to a method to produce a low-temperature co-fired ceramic structure comprising: providing a precursor green laminate comprising at least one layer of core tape wherein said tape has a dielectric constant of at least 20; firing said precursor green laminate during a first firing to form a high dielectric constant ceramic core; providing one or more layers of metallized low dielectric constant primary tape; laminating one or more layers of said metallized low dielectric constant primary tape to said core; and firing said core and primary tape layers during a second firing.
