Acoustic microscopy techniques analyze the intensity and phase of both the reflected and transmitted waves to create visual images reflecting the variations in the acoustic impedance of the specimen, thereby disclosing internal flaws and defects such as delamination and voids.

SAM uses ultrasound waves to detect changes in acoustic impedances in integrated circuits (ICs) and other similar materials. Pulses of different frequencies are used to penetrate various materials to examine sample interiors for voids or delamination. MuAnalysis performs C-mode SAM (or C-SAM), with both reflective and through-scan capabilities.

Mar 13, 2019 · Scanning acoustic microscopy (SAM) also denominated acoustic micro imaging (AMI) and scanning acoustic tomography (SAT) is a consolidated and recognized tool for quality control, inspection and failure analysis of microelectronic components and materials.

SAM (also known as ultrasonic microscopy and C-SAM, or confocal scanning acoustic microscopy) is a common failure analysis method in materials science. It is used for quality control and development of microelectronic components, including those encased in plastic, printed circuit boards, and silicon wafers.

The C-SAM®, or C-Mode Scanning Acoustic Microscope, is a very high frequency pulse-echo ultrasonic microscope that generates images by mechanically scanning a transducer over a sample. A highly focused beam of ultrasound, generated by an acoustic lens, is brought to the sample by a coupling medium, usually water or an inert fluid.

Scanning Acoustic Microscopy (C-SAM) has revealed as the most effective and complete non-destructive approach for the detection of critical and latent anomalies within COTS and plastic encapsulated microelectronics. C-SAM Meaning.

In this regards Scanning Acoustic Microscopy (SAM) is one of preferred methods for the non-destructive inspection of microelectronic assemblies and components. Flip Chip systems (CGA, FCBGA, PBGA, FPBGA…) MEMS…

Integrated components (ICs), microchips, bonded wafers, metals, ceramics, composites, and many other materials and systems can be inspected for quality of bonding/delamination, voiding, and numerous other defects can be imaged rapidly.

Scanning Acoustic Microscopy (CSAM) is a non-invasive technique used to non-destructively inspect for construction details, defects or the integrity of an optically opaque solid sample, component, material or structure.

Confocal Scanning Acoustic Microscopy (C-SAM) is a non-destructive and non-invasive method to quickly provide high precision acoustic imaging on discrete planes of a packaged part. Sage …
