Sub-micron 3D X-ray Inspection

3D X-Ray Inspection

In order to investigate many packaging designs, constructions, and failures, it becomes imperative to be able to get a broad picture of the physical properties before any destructive analysis occurs. Removing any chance of sample damage or mishandling, packaging failures can be caught undisturbed with Sage Analytical Laboratories’ new high precision sub-micron 3D X-ray Inspection Computed Tomography system.

The basic principles behind creating a tomography for 3D x-ray inspection are simple. Hundreds or thousands of 2-dimensional x-ray captures, each taken at slightly different angles are stitched together using state of the art software to create an interactive software reconstruction of 3-dimensional samples. The applications of this are incredibly versatile and sum to a magnificent time saving in analysis.

One of the largest benefits beyond the non-destructive nature of the analysis is that nearly any virtual cross section may be analyzed. This is especially useful while inspecting for metal bridging, foreign materials, or construction issues. By being able to view all three planes of a cross section, information can be gathered that would have been destroyed in a physical cross section. Any view may be partitioned out and viewed separately for greater detail. Images and even short movies can be generated to fully show the nature of the defect present. Furthermore, even post physical destruction, the volume created can be analyzed for more information if necessary.

Applications to consider:

    • Wire bond placement and path
    • Wire bond ball and wedge inspection
    • On-laminate C4/bump inspection
    • BGA fatigue
    • BGA cracking
    • BGA/C4/Bump voiding
    • Copper tracing in laminate, substrates, and boards
    • Passive component integrity and placement
    • Die attach issues
    • Various other metal defect mode detection

Depending on the sample type and the quality/resolution needed, scans for 3D x-ray inspection may take between minutes, to a full day. If you have any questions about sample size, type, scan time, or feasibility of a scan, please do not hesitate to contact us.
