摘要:
In a device for the detection of thermal radiation and a method for production of such a device, a stack is formed with a detector support having a detector element for converting the thermal radiation into an electric signal, a circuit support with a read-out circuit for reading out the electrical signal and a cover to shield the detector element. The detector support and the cover are so arranged that a first stack cavity is formed between the detector element and the cover and a second stack cavity is formed between detector support and the circuit support. The first stack cavity and/or the second stack cavity is evacuated and hermetically sealed. In the manufacturing operation, functionalized silicon-substrates are stacked upon one another, firmly bonded together and subsequently sub-divided. Preferably, the detector elements are pyro-electric detector elements. The device finds application in motion detectors, presence reporters and thermal-image cameras.

The present embodiments relate to a magnetic resonance local coil with a receive antenna for receiving magnetic resonance signals. The magnetic resonance local coil also includes a transmission unit for transmitting magnetic resonance signal data generated on the basis of the magnetic resonance signals via a data transmit antenna of the magnetic resonance local coil to a signal data receiving unit of a magnetic resonance tomography systems. The transmission unit is provided, at least in sections, with screening with a first metal coating and a first dielectric coating.
摘要:
In a method for producing a multilayer encapsulation (1) of a piezo actuator (5) such that the piezo actuator (5) is protected towards the outside without having to use an additional enveloping housing-type structure, in order to produce the multilayer encapsulation (1), an electrically insulating elastic layer (10) is first applied to the surface of the piezo actuator (5), whereupon a metallic layer is applied to the electrically insulating elastic layer (10) so as to planarly cover the same.
摘要:
According to various production methods for producing a piezoceramic multilayer actuator, in the course of the production method, multilayer locks (10) are electrochemically or mechanically processed in such a way that a recess structure is obtained. The lateral surfaces (22; 24) of the electrodes (20) inside these recesses are electrically insulated using the slip casting method in order to be able to contact the remaining electrodes by imprinting an outer metallization.

摘要:
One unhoused electronic component, e.g., a semiconductor power component, has at least one connecting surface disposed on a top side and/or on a bottom side for fastening and/or for electric contacting. One side of the component is attached to and/or electrically contacts a direct copper bonding ceramic substrate, at an opposing connecting surface in the region of the connecting surface. An electrically insulating carrier film is created on the substrate on the side facing the component outside the region of the connecting surface and extending beyond the bottom side. An electrically conducting conductor part is attached to and/or electrically contacts the connecting surface on the top side. A pre-formed, three dimensional structure is formed extending beyond the area of the top side, thus creating an electrically insulating mass between the carrier film and the three-dimensional structure of the conductor part.

摘要:
A method for the production of an encapsulated and at least partly organic electronic device wherein the device comprises a combination of three groups of different electronic units or components which may be separate discrete structures arranged to be produced independently from one another electrically conductively interconnected, the groups including inorganic units, passive units and active units or active components such as antennae, diodes (rectifier diodes and/or light-emitting diodes), some of which units may be organic, e.g., organic transistors, and so on, and forming a resulting optimized circuit. The components of the three groups of units forming the resulting circuit are combined on a one piece flexible substrate film which can also serve as an encapsulation layer for the device.
