  • Patent number: 10816411
    Abstract: A microheater performs a self measurement of its own temperature. The microheater has an electrically resistive element which generates heat when a voltage has been applied across the resistive element. The resistive element has an electrical conductivity that is a function of its temperature. A measurement device is positioned within the microheater body and is configured to measure conductivity of the resistive element. An electronic processor, that may be incorporated into the microheater, controls brief interruption of the heating voltage and application of a lower voltage for measuring conductivity. The lower voltage is insufficient to increase the heat output of the microheater, and is applied for too short of a period to allow excessive cooling of the microheater. A microprocessor receives and processes the data obtained from measuring conductivity.

The connection layer (20) can for example be an adhesive, soldered, welded, sintered connection or another known connection that connects joining partners while forming a material connection. Furthermore, a reinforcement layer (30?) is arranged adjacent to the connection layer (20) in a bonded manner. The reinforcement layer (30?) has a higher modulus of elasticity than the connection layer (20). A particularly good protective effect is achieved if the reinforcement layer (30?) is formed in a frame-like manner by an outer and an inner boundary (36, 35) and, at least with the outer boundary (36) thereof, encloses the connection face (11) of the at least one electric and/or electronic component (10).

  • Patent number: 8925193
    Abstract: A method, and apparatus resulting from the method, for fabricating a circuit board suitable for mounting electronic components. The method includes drilling a plurality of through-holes in a plurality of dielectric sheets, forming a conductive film on at least one side of each of the plurality of dielectric sheets, and substantially filling each of the plurality of through holes with a conductive material. The conductive material is both electrically and thermally uninterrupted from a first face to a second face of each of the plurality of dielectric sheets. The plurality of dielectric sheets are then sequentially mounted, one atop another, to form the circuit board. The sequential mounting step is performed after the steps of drilling the plurality of through-holes, forming the conductive layer, and substantially filling the plurality of through-holes.

    Abstract: A method for producing a semiconductor module includes providing an adhesion carrier and a plurality of circuit carriers. The adhesion carrier has an adhesive upper side and a lower side opposite the adhesive upper side. Each of the circuit carriers includes a ceramic carrier and an upper conductor layer applied to the ceramic carrier, and a circuit carrier lower side. By placing the circuit carriers onto the adhesive upper side, the circuit carrier lower side of the circuit carriers contacts and adheres to the adhesive upper side, so that a quasi-panel is formed, in which the circuit carriers are processed while preserving the quasi-panel and can then be removed from the adhesive upper side.

  • Patent number: 8906747
    Abstract: A method (30) of forming a semiconductor package (20) entails applying (56) an adhesive (64) to a portion (66) of a bonding perimeter (50) of a base (22), with a section (68) of the perimeter (50) being without the adhesive (64). A lid (24) is placed on the base (22) so that a bonding perimeter (62) of the lid (24) abuts the bonding perimeter (50) of the base (22). The lid (24) includes a cavity (25) in which dies (38) mounted to the base (22) are located. A gap (70) is formed without the adhesive (64) at the section (68) between the base (22) and the lid (24). The structure vents from the gap (70) as air inside the cavity (25) expands during heat curing (72). Following heat curing (72), another adhesive (80) is dispensed in the section (68) to close the gap (70) and seal the cavity (25).
