This paper reports, for the first time, the use of endoscopy for the nondestructive examination of solder joint integrity in chip scale packages (CSP) such as flip chip on flex (FCF). Borrowed from the medical instrument technology, the endoscope is used to examine visually the inside of an organ. This concept has now been developed and refined by ERSA and KURTZ, and led to an ERSASCOPE inspect...

This paper presents a nondestructive, high frequency electromagnetic evaluation method which can be applied for the examination of periodic conductive strips or conductive fibers using the evanescent modes generated in slits or in dielectric insulation between conductive fibers. For the detection of evanescent waves we propose the use of lenses with metamaterials, both conical Swiss roll type a...

This report provides general guidelines for the interpretation of published data on probability of detection (POD) for nondestructive testing. An overview is provided of the different types of probability of detection data, methods for statistical analysis and the assumptions that may be embedded in these analyses. Four key issues have been identified which need to be addressed when assessing t...

This paper presents to use the Resonant Ultrasound Spectroscopy (RUS) as nondestructive examination method for determination of the density changing, elastic and geometrical properties of the object to be examined. The method is applied at the noninvasive evaluation of the femoral head prosthetic and of the artificial cervical discs made from yttria stabilized tetragonal zirconia. This method d...

This paper presents a data fusion method between the results of ultrasound using phased array at 5MHz frequency and those obtained through eddy current examination at 1-10MH frequency. The obtained results are compared with destructive tests, a very good correlation being obtained. The effects of delamination over the properties of CFRP are studied using dynamic mechanical analyzer, emphasizing...

Measurement of surface displacements resulting from acoustic wave propagation in solids has been used extensively in determining elastic properties of materials [1], [2]. Additionally, examination of acoustic wave propagation in materials has been used as a nondestructive tool in testing the integrity of structures, evaluating the size and position of bulk material defects, determining material...

A framework for an intelligent fusion of outputs from a combination of the state of the art nondestructive testing techniques of highway bridges and parking garages is described. A hybrid artificial intelligence system that automates the decision-making process is employed for the examination of the results obtained from various nondestructive testing methods. Neural networks, fuzzy logic, as w...
