Abstract: A ceramic substrate includes a stack of layers that contain a ceramic material and that are sintered together. One layer, such as a top layer in the stack, has a higher proportion of a sintering agent than an adjacent layer. A metal paste may be applied to a top layer of the stack.

Abstract: The arrangement has a piezoelectric transformer and a support (2), where the transformer includes a body (1) in form of a plate. The transformer works with thickness mode vibrations, and the body is firmly connected with the support in circumferential edge areas (11, 12, 13, 19), in which wave bulges of a horizontal oscillation of the body arise. The edge area (11) of a main surface of the body is firmly connected with the support by connecting units (34). The connecting units are spaced apart from each other in a circular direction.

Abstract: Production of a ceramic body comprises forming particles of a sort A and a sort B each having an expansion of at least 5 microns m and each comprising a ceramic material based on a mixture of silver oxide, niobium oxide and tantalum oxide; forming a particle mixture by mixing the different sorts of particles; producing a blank by pressing the particle mixture; and sintering. Preferred Features: The particles contain the ceramic materials in granular form held by a binder. The particles are produced from a suspension made from a calcinate of the composition A and B.

Abstract: The invention relates to an electric component comprising a carrier (1) and a chip (5) which is fixed on the carrier while being conductively connected to the carrier (1). The component comprises a shielding cover (2) the lower side of which is connected in a peripheral region to an earthing contact (32) of the carrier (1). The chip (5) is disposed in a cavity (21) between the carrier (1) and the shielding cover (2) and comprises contacts which are each connected to a signal line (78, 79) disposed in the carrier (1). The respective signal line (78, 79) forms a coaxial bushing filter (11) with the conducticve surfaces (3) which are arranged in the carrier (1) and connected to the ground. The respective coaxial bushing filter (11) protrudes beyond the base surface of the shielding cover (2) in a projection plane in at least one direction.

Abstract: A module for electrical components is proposed in which connection surfaces that can be bonded are provided on a multi-layer substrate with integrated wiring; a component chip is bonded on the top that has bond pads on its surface pointing upward and that contacts the substrate by means of bonding wires. Here, the wire guide of the bonding wires is so that they are each bonded with a ball on a connection surface and with the wedge directly on one of the bond pads.

Abstract: A ceramic mixed system is proposed that includes a two-phase mixture of pure components A and B, wherein phase A is based on the cubic to tetragonal modification of Bi3NbO7 and phase B is based on a monoclinic pyrochlore modification of Bi2(Zn2/3Nb4/3)O7. The electrical properties of ceramics produced therefrom make the material suitable for components having a multilayer structure in which capacitors and inductors are integrated and which can be used in data processing or signal processing.

Abstract: Capacitor comprises two or more electrode layers (1) lying opposite each other with dielectric layers (2) between them. The dielectric layers are made of a ceramic material containing two different components in a phase different from the other. The components have a perovskite structure with silver on the A positions and niobium and tantalum on the B positions. Components A and B are selected so that the temperature coefficients of their dielectric constants have different polarities in a temperature range. - Preferred Features: The dielectric layers have a thickness of 1-50 microns . The ceramic material contains boric acid as sintering aid.
