...for Microelectronics Failures

Scanning Acoustic Microscopes (SAM)

With the complexity of modern packaging comes a plethora of new fail signatures that are hard to isolate using conventional techniques.

With Sage Analytical Laboratories new Okos Scanning Acoustic Microscope (SAM), multiple fail types can be detected and isolated in a non-destructive manner.

 

 

 

These fails include but are not limited to:

    • Voiding in a package or laminate
    • Voiding in underfill
    • Delaminations
    • Die cracking
    • Contact non-wets
    • Damaged C4s and interconnects
    • Wirebond disconnects
    • Ball bond disconnects

As per the Okos website, other benefits and specifications are as follows:

SAM APPLICATIONS

    • Counterfeit Detection
    • Product Reliability
    • Process Validation
    • Vendor Qualification
    • Product Inspection
    • Quality Control
