X-ray starts with a sample being irradiated by an X-ray source and projected onto a
detector. The geometric magnification M of the image is the ratio of focus-detector

the greater the resolution. With the nanofocus technology an unique detail detectability down to 0.2 microns can be achieved. phoenix|x-ray systems reach geometric

The View Inside
Why to inspect solder joints with X-ray?
The reliability of electronic assemblies strongly depends on solder joint quality. Acceptability criteria are mainly based on shape
and dimension of the solder joints. As quality demands and technology for assembly process for new package types increase,
many solder joints are no longer directly visible. Fortunately, they can easily be inspected by advanced microfocus and nanofocus X-ray systems. phoenix|x-ray offers dedicated analysis and automatic inspection solutions for any type of solder joint:

BGA type solder joints such as PBGA, CBGA, CGA, etc.

All dimensions and features of the solder joint are imaged: diameter,
thickness (grey value), lands and contact areas (darker and brighter

circles), voids (bright spots). All defects that have any influence on the
solder joint's shape are detectable:
Bridges, opens, missing joints, warpage, popcorning, component tilt,
voids, diameter deviations, roundness, shape deviations (roundness),
fuzzy edges (insufficient reflow), misregistration.

The Third Dimension
Just look from the side
ovhm - oblique views at highest magnification
Some acceptability criteria refer to a side view and many
defects can be seen best from the side, in other words, some
information about the vertical dimension is required.
phoenix|x-ray systems provide this information by oblique view
– up to 70 degrees – at highest magnification. As an
example, this enables the user to see open BGA solder joints
directly instead of interpreting signatures.

the profile of these CSP solder joints is fully displayed and even the void position can
be clearly determined. In contrast to 45 degrees, at 70 degrees the component and
board pads are completely separated and can be inspected without any interference.

designed to enable oblique views of up to
70 degrees and 0 to 360 degree rotations without a decrease in magnification.
Magnification remains the same because
the distance between focus and sample
does not change while the detector is being tilted.

Automated Inspection
The efficient way of process control and rework
Efficient soldering process control requires the acquisition of statistical data on the solder joints of a larger number of samples.
phoenix|x-ray offers a range of plug-in software modules for the automated evaluation of standard solder joints like BGA, QFP,
QFN, or PTH. For non-typical interconnections, appropriate modules can quickly be customised with the XE² (X-ray image Evaluation Environment) software. Together with the high precision CNC manipulation which comes standard with phoenix|x-ray
systems these modules enable the automated X-ray inspection (AXI) of solder joints at minimum set-up time, due to teach-in
programming and auto-setup routines. An additional software package – quality|review – is the perfect connection to rework.
phoenix|x-ray's inspection modules can also easily be activated during manual inspection as a quick inspection aid.

phoenix x|act µAXI
Fully automated CAD based high-resolution X-ray inspection for extremely high defect coverage
As a solution for µAXI with high magnification and repeatability, GE provides calibrated high precision offline µAXI systems including the unique
phoenix x|act software package for fast and easy offline CAD programming. Small views with a resolution of up to a few micrometers, 360° rotation and oblique viewing up to 70° ensure to meet highest quality standards. Besides the automated X-ray inspection, the μAXI system can be
used for manual failure analysis or 3D computed tomography as well.

throughput of the SMT line. Principally, X-ray inspection takes much more time
than AOI. The higher the defect coverage, the more inspection time is required.
For zero defect production inspection with small fields of view with micrometer
resolution, 360° rotation and oblique viewing up to 70° is essential. To ensure
these higher defect coverage requirements, μAXI has to be performed beside
the production line.

spots well below one micron while maintaining the highest intensity needed.

software modules include all X-ray accessible criteria mentioned in the commonly
applied standards for acceptability of PCB
assemblies, namely:

•	 IPC-A-610 Revision E
•	 IPC 7095
The modules are continuously updated to

Closed tube or open tube?
Closed tubes: All tube components are contained in a sealed vacuum vessel container.
Closed tubes are maintenance-free and are
completely replaced at the end of their lifetime.
Open tubes: All components and wear-out parts
are accessible and replaceable, the tube is continuously evacuated by a turbomolecular pump.
Open tubes yield higher resolution and magnification and are not limited in lifetime.
