In order to detect defects in the surfaces of dry fabric and composite prepreg, this new vision-based tactile sensor roller prototype, TacRoller, is a three-colour reflective membrane roller-shape ...

Researchers have improved flaw detection to increase confidence in metal parts that are 3D-printed using laser powder bed fusion. Researchers at the Department of Energy's Oak Ridge National ...

Improved ultrasonic (UT) inspection methods address storage tank integrity monitoring and assessment without removing tanks from service. By acquiring large amounts of high-density UT data and ...

Nondestructive testing (NDT) refers to the inspection of materials to ensure their integrity and serviceability without damaging the components in the process. There are various NDT methods used by ...

Similar to the way in which radiography is used clinically for the identification of breaks or cracks in a patient’s bone(s), manufacturers utilize this method to identify cracks or flaws within their ...

The increasingly complex structures, 3D geometries, and new material combinations in state-ofthe-art chips gives rise to a huge demand for new metrology tools. Traditional methods do not suffice, for ...

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 ...

Magnetic flux leakage (MFL) testing is a widely established non‐destructive evaluation technique used to assess the integrity of ferromagnetic materials in applications such as pipeline inspection and ...

Recent recalls, including that of American Regent?s caffeine and sodium benzoate injection on May 5, 2011, highlight the importance of particulate inspection, and they might lead observers to ask ...

Variation is becoming a bigger problem in multi-die assemblies with TSVs and hybrid bonding. Multi-modal approaches are required to test these devices. AI plays a role in improving defect capture rate ...

ORNL researcher Zackary Snow compares data from different types of images collected during and after metal parts were additively manufactured using a powder bed printer like the one behind him.
