The small and complicated features of TSVs give rise to different defect types. Defects can form during any of the TSV ...
Researchers have designed a robust image-based anomaly detection (AD) framework with illumination enhancement and noise suppression features that can enhance the detection of subtle defects in ...
Researchers have developed a new method for detecting defects in additively manufactured components. Researchers at the University of Illinois Urbana-Champaign have developed a new method for ...
Xarion’s laser-excited acoustics (LEA) is a couplant-free nondestructive testing (NDT) method that uses laser principles and an optical microphone without a membrane. In a single-sided “pitch-catch” ...
Detecting macro-defects early in the wafer processing flow is vital for yield and process improvement, and it is driving innovations in both inspection techniques and wafer test map analysis. At the ...
The range of materials that concrete contains, such as stone, chalk, and sand, scatters normal sound waves, making clear ...
Longitudinal (top) and axial (middle) images of X-Ray CT data of parts with 6 internal defects: a spherical clog, a stellated shaped clog, a cone shaped void, a blob shaped void, an elliptical warp of ...
