The Applied Technical Services Family of Companies (ATS FoC) provides confocal scanning acoustic microscopy (C-SAM) testing and analysis to deliver detailed internal imaging of semiconductor components. When visual inspections alone aren’t enough to detect hidden defects, C-SAM provides high-resolution, non-destructive imaging to assess the integrity, reliability, and performance of semiconductor packages.
Semiconductor devices are composed of multiple bonded materials where defects can develop between the material layers over time. Using high-frequency acoustic imaging, our engineers can evaluate the internal interfaces and bonded layers without damaging or dismantling the component.
How is C-SAM Testing and Analysis Conducted?
Our engineers begin C-SAM testing and analysis by submerging the semiconductor package in deionized water, which transmits ultrasonic waves. A focused acoustic transducer scans the component, sending high-frequency pulses into the package. Advanced software captures and analyzes reflected waves from internal interfaces to generate detailed, layer-by-layer images. This process verifies package integrity in accordance with the relevant JEDEC, IPC, and MIL standards.
What Defects Can C-SAM Testing Detect in Semiconductors?
Manufacturers rely on C-SAM testing data to confirm that the quality of electronic components, semiconductor packages, and printed circuit boards meet strict design specifications. C-SAM is commonly used to support quality control inspections, reliability testing, and failure analysis investigations.
Common defects include:
- Delamination
- Voids and Separations
- Internal Cracks
- Fractures
- Air Pockets
- Moisture Damage
- Popcorn Cracking
- Incomplete Bonding
- Adhesions Failures
- Thermal Stress
- Die-Attachment Defects
- Underfills
