Description

CROSS-REFERENCE TO RELATED APPLICATIONS None. FIELD OF THE DISCLOSURE Aspects of the disclosure relate to analysis of three-dimensional images. More specifically, aspects of the disclosure provide an enhanced imaging analysis for three-dimensional scan acquisition and fiber/wire separation. BACKGROUND Fiber and/or wire three-dimensional image acquisition, separation and analysis in multiple electronic components is critical to ensure their reliability and the related failure analysis. The identification of failures and risks in electronic components with a complex three-dimensional structure and high density, such as transformers, is a challenging task. The acquisition of three-dimensional X-Ray images with high signal over noise ratios and their subsequent analysis, including fiber identification or separation is essential to allow these failure and risk analysis. The failure analyses allow precise identification of defects, artefacts, and process indicators, such as short-circuits, solder balls, and other metallic residues, as well as enamel wire overlapping, etc. The results of the failure analyses are then used to implement preventive or corrective actions, either at the component design specification level or on the manufacturing and assembly process. Conventional methods for analysis generally do not have sufficient image quality. Such images; furthermore, have noises inherent in the images and there is no method or algorithm for separating and analyzing the wires and/or fibers in components within complex three-dimensional structures. While the use of three-dimensional X-Ray images in the electronics industry is becoming a standard process, the methods used have many drawbacks. For example, data acquisition still has limitations linked with the mild signal over noise ratio for some heavy components and with the image post-processing methods, especially in components with a complex three-dimensional structure. Currently, there is no reliable and repeatable method for three-dimensional X-Ray image acquisition improvement for high density and highly complex parts. For three-dimensional parts, there are only empiric and unprecise methods for image post-processing for fiber and/or wire separation. There is a need to provide an apparatus and methods that are easier to operate than conventional apparatus and methods and that provide for analysis of complex three-dimensional components. There is a further need to provide apparatus and methods that do not have the drawbacks discussed above, namely, use of empirical methods that are imprecise for highly detailed parts used in industry. There is a still further need to provide a method for analysis of three-dimensional structures that is cost effective as well as precise and quick.
