摘要:
A crash apparatus, in particular a crash box in a motor vehicle, has a deformation body for absorbing energy in the event of a crash, which body is assembled from two half shells having beads running transversely to the main deformation direction. The two half shells each have outwardly projecting flanges with beads also running transversely to the main deformation direction. The two half shells exclusively press against one another via the contact surfaces lying between the beads of the flanges and are connected to one another in these areas.

The present invention relates to a device for testing an optoelectronic module, comprising a first source for generating an electromagnetic beam or particle beam, a second source for illuminating the optoelectronic module; and a detector. In addition, a method for testing an optoelectronic module is provided comprising illuminating the optoelectronic module, directing an electromagnetic beam or particle beam and detecting defects in the optoelectronic module. The illumination additional to the electromagnetic beam or particle beam makes defects visible which otherwise would not be detected.

The invention relates to a method of calibration of the beam position of a corpuscular beam. A calibration body with structures is used, wherein the structures have a structure period PS in the plain section and within each structure there is a position L intended for the measurement. For the calibration, at least one detection signal each at structures in the plain section of the calibration body is generated, wherein the corpuscular beam is deflected with deflectors on beam target positions L1 with the beam target period P1, which is larger than half of the structure period PS, whereby a basic calibration is used for the control of the deflectors, and wherein the beam target deflections deviate either in the beam target period P1 from the structure period PS and/or in the beam target position L1 from the position L.

A method for testing a plurality of electronic devices formed on a large area substrate is described. In one embodiment, the method includes transferring a substrate on an end effector relative to a testing platform having a plurality of testing columns coupled thereto, the substrate having a plurality of electronic devices located thereon, and moving the substrate in a single directional axis relative to an optical axis of each of the plurality of testing columns, the single directional axis being substantially orthogonal to the optical axis to define a test area on the substrate, wherein the test area is configured to cover an entire length or an entire width of the substrate such that the testing columns are capable of testing the entire substrate as the substrate is moved through the test area.
摘要:
The present invention provides a method of electron beam testing of liquid crystal displays comprising non-uniform electrodes having a conductive portion and a dielectric portion. In accordance with methods of the present invention, the diameter of the electron beam is increased so that the beam is less focused, i.e., enlarged or “blurred,” over a non-uniform electrode area. The diameter of the beam is increased so that the beam generates secondary electrons from the conductive portion of the non-uniform electrode area. The configured test beam may be circular, elliptical, or other suitable shapes.
摘要:
An electric machine designed as a starter, generator, or starter-generator for a motor vehicle and presenting a housing, wherein said housing comprises a winding with coils or coil groups including connector heads. It comprises power electronics units with power switch components distributed along the perimeter of the housing, as well as conductor rails connected with power electronics units, and coil exit rails going from a power electronics unit to an associated coil or coil group. Said power electronics units are arranged on the face of the housing in a clearance created by the connector heads, which are located radially outside or inside the connector heads. Said power switch components comprise a contact area and are arranged directly—without inserted electric insulation—on one of the power loops or a coil exit rail.

Disclosed in a power semiconductor module which includes a stack of carrier substrates, disposed one above the other in multiple layers and provided with at least one conductor track on at least one main surface, in which at least one electronic semiconductor component is disposed between two adjacent carrier substrates of the stack and is contacted electrically and heat-conductively to at least one conductor track of a carrier substrate disposed in the stack above the semiconductor component and to at least one further conductor track of a carrier substrate disposed in the stack below the semiconductor component. To both improve heat output and provide a compact design, the two outer carrier substrates of the stack are embodied as one upper and one lower housing wall of a closed housing part surrounding the at least one semiconductor component, and the interstices between the stacked carrier substrates are tightly closed by an encompassing wall secured to the carrier substrates.
摘要:
A method and apparatus for testing a plurality of electronic devices formed on a large area substrate is described. In one embodiment, the apparatus performs a test on the substrate in one linear axis in at least one chamber that is slightly wider than a dimension of the substrate to be tested. Clean room space and process time is minimized due to the smaller dimensions and volume of the system.
摘要:
A method and apparatus for reducing or eliminating crosstalk between a plurality of electron beams is described. The plurality of electron beams may produce test areas on a large area substrate that are adjacent wherein secondary electrons from one test area may be detected in an adjacent test area. In one embodiment, the timing of a primary beam emission and detection of secondary electrons from that primary beam is controlled to eliminate or reduce the possibility of detection of secondary electrons from another primary beam.
