20090134275 | Metallic aircraft component - The invention relates to metallic aircraft components which can preferably be used for aircraft structures in the fuselage region. A damage-tolerant design is usual for aircraft components in the fuselage region. It is the object of the invention to provide metallic components in which metal sheets are connected to one another by weld seams which have an improved damage tolerance behavior and fatigue crack propagation behavior. In an aircraft component in accordance with the invention, at least two metal sheets are welded to one another as butt joints. The centerline of the join line of the weld seam is predetermined by the outer edge contour of the metal sheets connected to one another. In this connection, it is formed deviant from a continuously straight line shape such that the total length of the weld seam is increased by changes in direction periodically occurring at the edge contours engaging into one another in a complementary manner. | 05-28-2009 |
20090277888 | SYSTEM AND METHOD FOR MANUFACTURING WELDED STRUCTURES, AND A WELDING ADDITIVE MATERIAL FOR THIS PURPOSE - A system and method for manufacturing welded structures comprises components to be welded, a welding additive material which, before the welding, has a shaped profile and the shaped profile is disposed between components to be welded and conforms with at least one of the components to be welded. At least one heat source is used in the method to weld the components, producing a weld seam on at least one side of one of the components. | 11-12-2009 |
20100065612 | Filler Material, In Particular For Improving The Quality Of A Joint Seam Formed During Thermal Joining Of Two Metallic Structural Components - A filler material improves the quality of a joint seam formed during thermal joining of two metallic structural components and includes a core and a coating that surrounds the core at least in sections Because the filler material comprises a coating on the core, the alloying material for the coating may be selected largely independently of any possibly limiting metallurgical requirements in relation to the base material for the core so that with the use of the heterogeneous filler material optimal joint seam characteristics of the joined structural components always result, largely irrespective of the materials composition of the core If an essentially H-shaped cross-sectional geometry of the filler material used, moreover, preliminary fixing or alignment of the structural components that are to be joined in a thermal joining process becomes possible. | 03-18-2010 |

20080212078 | ARRANGEMENT AND METHOD FOR FOCUSING A MULTIPLANE IMAGE ACQUISITION ON A PROBER - The invention relates to a system and a method for capturing images in a prober. According to the invention, the surface of a test object is illuminated in succession with light of a first, second and third color; and an image capturing device records a gray scale image of the surface; and a composite image is produced from the three gray scale images by means of an image evaluating device. The object of the invention is to qualitatively improve the image capturing, in order to raise the positioning accuracy by means of an improved display, as a result of which, finely structured test objects can be used. This object of the invention is achieved in that the lighting device is designed as a unit, which can be controlled by the image evaluating unit and which produces at least three colors and which exhibits at least one light emitting diode (LED) as the lighting means. | 09-04-2008 |
20080284457 | METHOD AND APPARATUS FOR CONTROL OF A POSITIONING DEVICE - In a device and a method for positioning an object, a drive of a movement device is controlled. To this end, a visual joystick is actuated, as a result of which a moveable actuator is moved, at least linearly by means of a display of a control unit of the movement device, into a position, in which a direction of movement, which can be implemented with the drive, is displayed symbolically. The drive for the movement of the object in the displayed direction of movement is initiated by means of a switching function of the actuator. | 11-20-2008 |
20080315903 | METHOD FOR MEASUREMENT OF A DEVICE UNDER TEST - A method is disclosed for measurement of wafers and other semiconductor components in a probe station, which serves for examination and testing of electronic components. The device under test is held by a chuck and at least one electric probe by a probe support and the device under test and the probe are selectively positioned relative to each other by a positioning device with electric drives and the device under test is contacted. The drive of the positioning device remains in a state of readiness until establishment of contact and is switched off after establishment of contact and before measurement of the device under test. | 12-25-2008 |
20110013011 | ARRANGEMENT AND METHOD FOR FOCUSING A MULTIPLANE IMAGE ACQUISITION ON A PROBER - A focused multi-planar image acquisition in real time even while a test object is moving, is achieved with a system and a method for a focused multi-planar image acquisition in a prober. When a surface of a test object is positioned laterally in relation to tips of separated probe needles, a microscope is focused on the surface of the test object at a first time and on a plane of the probe needles at a second time. The objective lens is provided with a microscope objective lens focusing system, which can focus the objective lens, independently of a vertical adjustment drive of the microscope, on the surface of the test object in a first focal plane and in a second focal plane, which is on a level with the probe needle tips. | 01-20-2011 |
20140145743 | MODULAR PROBER AND METHOD FOR OPERATING SAME - The invention relates to a prober for checking and testing electronic semiconductor components and methods of using the same. The prober comprises at least two checking units, each of which is equipped with a chuck, probes, and a positioning unit, and each of which is assigned to a machine control system and a process control system. The prober further comprises a loading unit for automatically loading both testing units and an additional loader for manually loading at least one of the testing units, a user interface, and a module control system for controlling the process control systems and/or the machine control systems and the loading unit. The user interface can optionally be connected to at least one of the process control systems or the module control system by means of a switching device of the prober. | 05-29-2014 |
