    摘要： A fabrication process for ferrite toroids which utilizes ferrite ceramic tape having an improved elongation characteristic. The process utilizes a set of rigid mandrels which are employed in the final lamination to support the rectangular cross section of the internal cavity of a respective ferrite tube, thereby reducing stress concentration and permitting the highest lamination pressure to be used in the final step. The mandrels are removed prior to panel densification. The tape and mandrels operate together to minimize cracks and pores in the toroids and provide an added advantage of maintaining high tolerances in the internal cavity dimensions as well as the cavity-to-cavity alignment.

    摘要： A method for producing ceramic tape used to fabricate electronic devices while eliminating continued shrinkage of the unfired tape. Chemical agents are added to a mixture of ceramic powder and binder to manipulate the crosslinking of the binder. A first approach involves promoting the crosslinking reaction to completion quickly. The second approach involves preventing the crosslinking reaction during the tape slurry mixing and casting processes. A solvent is used to accelerate the crosslinking of the binder in which the solvent may include one or more of acetone, acetylacetone, toluene and ethanol. Preferably, the solvent is a combination of acetone and acetylacetone. A polyhydroxy compound, such as glycerine, may be added to accelerate the crosslinking reaction of the binder. The boron in the tape may alternatively be rendered inoperative as a crossing agent for the binder by pre-reacting the boron with the Lewis base prior to contact with the binder. The preferred Lewis base is an organic amine, such as piperidine.

    摘要： A planar phase shifter formed of multiple layers of a ferrite. Selected layers of the ferrite are patterned with a conductor and the multiple layers of magnetic dielectric and conductor are cofired. The phase shifter is fabricated by first obtaining ferrite powder. Then, layers of the ferrite are made, preferably by tape casting. Next the ferrite layers are metallized by applying selected amounts of conductive metals in a selected pattern upon the tape. Selected numbers of vias are placed through selected layers of tape and conductive metal is placed in the vias to provide vertical connections through the layers. The tape layers are then stacked in a predetermined order and are laminated. The laminated stack of layers is then fired to a temperature of approximately 800.degree. C. to 1000.degree. C., sintering the laminated layers into one integrated structure.

    摘要： A method for forming a low temperature cofired ceramic package which is made using a multi-layered densified spherical powder formed via a sol-gel process. This densified powder is formed from layers of SiO.sub.2 reacted with trimethyl borate. The spherical powder has a preselected particle size and boron content sufficient to render the low temperature cofired ceramic package fully dense, even in the presence of a second phase filler ceramic, at a sintering temperature below 1000.degree. C. Binder material is added to the spherical powder and ceramic filler to form a plurality of tapes. A ceramic assembly is then formed by layering the plurality of tapes upon one another and firing the ceramic assembly at a temperature below 1025.degree. C. to form a fully dense cofired ceramic package. In order to form the multi-layered densified spherical powder, a silica core, which is formed using a sol-gel process, is reacted with trimethyl borate. An additional layer of silica is provided upon the reacted product which, in turn, is reacted with trimethyl borate. This process is continued until a spherical powder of desired size is formed.
