High Resolution Computing Laminography
Typ
Walk-in CT/HRCL facility
Geräteklasse
X-ray machine
Hersteller
Fraunhofer IKTS / TISAD GmbH
Anwendung
- High-resolution, non-destructive inspection of structures and components on or in planar substrates
(e.g. solder contact analysis on components such as BGAs on printed circuit boards) - Error analysis and defect search
- Quality control
- Inspection of hidden joints
- Analysis of constructions
Eigenschaften
- Full protection laboratory system according to RÖV
- 225 kV microfocus X-ray tube, cone beam projection
- 4 MPixel scintillation detector (2,000x2,000 pixels)
- High-resolution examination of partial areas of large-area printed circuit boards (up to 3 µm real voxel resolution)
- No preparation effort for high resolutions (compared to standard CT)
- Particularly suitable for failure analysis of solder contacts of Chip components, BGAs, QFNs, QFPs etc.
