Verfahren zur zerstoerungsfreien Fehlerdiagnose an Verbundbauteilen mit einem Kern aus einem Metall- oder Keramikschaum

DE1004011566 B UPAB: 20050805 NOVELTY - The method involves coupling ultrasonic waves into the component with an actuator mounted on the outer surface of one of the elements and detecting ultrasonic measurement signals with an acoustic detector on the opposite side of the core, determining the time until a threshold is exceeded by the measurement signals and/or determining the absolute magnitude of the measurement signal in a period between starting to couple in ultrasonic waves and a defined time and using the time and/or maximum value for fault diagnosis. USE - For non-destructive fault diagnosis of composite parts with core of metal or ceramic held on opposing sides by elements of homogeneous material with constant speed of sound. ADVANTAGE - Enables more reliable detection of faults

Coalescence analysis for evolving foams via optical flow computation on projection image sequences

A novel image-processing procedure is proposed for the analysis of sequences of two-dimensional projection images. Sudden events like the merging of bubbles in an evolving foam can be detected and spatio-temporally located in a given projection image sequence. The procedure is based on optical flow computations extended by a forward-backward check for each time step. Compared with prior methods, efficient suppression of noise or false events is achieved owing to uniform foam motion, and the reliability of detection is thus increased. The applicability of the proposed procedure in combination with synchrotron radiography is illustrated by a series of characteristic studies of foams of different kind. First, the detection of single-bubble collapses in aqueous foams is considered. Second, a spatial distribution of coalescence events in metals foamed in casting molds is estimated. Finally, the structural stability of polymer foams containing admixed solid nanoparticles is examined.Peer Reviewe

Microsystem and microelectronic devices investigated by synchrotron-radiation imaging techniques

Due to increasing packing density and ongoing miniaturization there is a growing need for non-destructive quality assurance of devices in microsystem technology, especially for techniques providing high spatial resolution. The tendency towards short electrical interconnections often results in burried structures which cannot be verified visually. In laboratories, various x-ray techniques are routinely applied to provide non-destructive insight into materials and devices. Successful application to microsystem devices is sometimes restricted, however, for instance due to limited spatial resolution and/or intensity of laboratory x-ray imaging setups. X-ray imaging using synchrotron radiation allows us to overcome a number of limitations. This paper introduces principles of both laboratory and synchrotron methods and shows their applications to imaging of microelectronic devices. Typical tasks of quality inspection usually accompanying the microsystem development cycle are demonstrated by examples of various fields of application. High-resolution and phase-contrast radiography is used to detect delaminations between substrates and glob tops encapsulating wire-bonded devices. By threedimensional (3d) imaging techniques as computed tomography (CT) we are able to image objects three-dimensionally with a spatial resolution down to the submicrometre scale. Recently, synchrotron-radiation computed laminography SRCL) has been implemented to image three-dimensionally flat and laterally extended objects with high spatial resolution. Examples of flip-chip bonded and wire-bonded devices highlight the potential of SRCL in typical microsystem applications like the detection of ?m-sized voids within flip-chip solder bumps along with their 3d positions in the bump. Moreover, as demonstrated by the study of two-dimensional hybrid x-ray sensor arrays with a high number of flip-chip interconnections, diffraction imaging methods have been developed and applied to investigate lattice deformations due to stress in (mono-)crystalline materials
