Scanning Acoustic Microscopy (C-SAM)
Equipment: Sonoscan
Working Principle
- Create images by generating a pulse of ultrasound
- Probe the area of interest vertically as depth changes
- Reflect the interface based on the materials
Technical Information
- Layer by layer analysis of DUT along the depth
- Acoustic and optical images show all of the underfill voids, die cracks, and material defects
