Head-on-Pillow Defect Detection: X-Ray Inspection Limitations

3D X-ray CT for BGA/CGA Workmanship Defect Detection

Combination of Information from Several X- Ray Images for Improving Defect Detection Performances – Application to Castings Inspection

The results presented were obtained in the frame of the European QUME project, during which three Non Destructive Techniques were developed to improve inspection of castings : multi-angle radioscopy, X-ray spectrometry and vibration analysis. We present the concept of confidence level (the so-called mass function of the Evidence theory) assigned to the information delivered by each method. A si...

Common Process Defect Identi Fication of Qfn Packages Using Optical and X-ray Inspection

The Quad Flat Pack No Leads (QFN) style o f leadless packaging [also known as a Land Grid Array (LGA)] is rapidly increasing in us e for wireless, automotive, telecom and many other areas becaus e o f its low cost, low stand-off height and excellent thermal and electri cal properties. With the implementation of any new package type, there is always a learning curve for its use in design and pro...

Cargo Container X-ray Inspection Systems

OVERVIEW: Container inspection is categorized into three stages. In the initial stage, large-size X-ray DR (digital radiography) is used to inspect full containers sitting on their trailers. If that inspection identifies suspicious cargo, the trailer and container are relocated to a nearby inspection position for opening the container and inspecting all cargo inside. In the second stage, small-...
