Do You Know about SAM?
Scanning Acoustic Microscopy
 
1. What's SAM?
 
Scanning Acoustic Microscopy (SAM) 
- Is a non-destructive analysis  shows unique insight on the integrity of package and device construction.
- Can detect void formations, delaminations, cracks and fractures or other hidden internal defects.
  
2. Types of Scan used for SAM

 

B-Scan

- Generates a top-down or X-Z axis cross-sectional image of the parts.
- Acoustic data collected along an X-Z or Y-Z plane versus depth using a reflective acoustic microscope (pulse/echo system).
  
 

C-Scan

- The C-Scan or pulse-echo provides a planar view image at a specific depth.
- Illustrations of delaminations and void formation can be generated.
- Acoustic data collected in an X-Y plane at depth (Z) using a reflective acoustic microscope (pulse/echo system)
 
  

T-Scan (Through Scan)

- Shows a two-dimensional (area) image of transmitted ultrasound through the complete thickness/depth (Z) of the sample/component
- Acoustic data collected in an X-Y plane throughout the depth (Z) using a through transmission acoustic microscope system
