Physical Analysis – DPA, for short – involves physically dismantling a device
to help determine whether it conforms to its design and material specifications
as well as its process requirements. Semiconductors, microcircuits, and passive
electronic devices are frequently submitted to this kind of analysis. And
AcousTech is frequently called upon to contribute, delivering primarily its C-SAM®
and X-Ray inspection services.
avail themselves of Destructive Physical Analysis at some time or another. Of
the industries we serve at AcousTech,
DPA is used most often by the aerospace industry to qualify electronic
components to Class “S.” Other common users of DPA include the military,
semiconductor manufacturers, test labs, medical device manufacturers, and the
that any type of electronic part or device can fail, all such items are likely
DPA candidates. Among the part types most often submitted to AcousTech are…
- PEMs (plastic encapsulated
microcircuits) such as SSOPs, SOICs, PLCCs, MSOPs, PQFPs/TQFPs,
- hybrid devices,
- flip chips,
- medical implants, and
- automotive sensors.
we use C-SAM®, X-Ray, or some combination of the two with these
items, our approach at AcousTech is the first step in nondestructively
identifying a number of potential problems. C-SAM® particularly excels
in exposing die surface delamination, leadframe delamination, delamination at a
wirebond, and cracks. We’ve found X-Ray inspection ideal for spotting lifted or
shorted wire bonds, excessive die-attach voiding, extraneous material,
excessive die-attach material, and chipped die edges.

- a quick turnaround,
- a detailed yet concise pass/fail
report that notes all defects discovered,
- a certificate of conformance, and
- a CD that includes all images
taken during the tests and/or the original X-Ray films.
