How does the rotating beam work?

How rotating beam work

• For devices on the focal plane:
− A device on the focal plane will be stationary.
− The beam will pass through the device at every angle as it rotates,
creating a three-dimensional, composite image of the device.
− Because the image is a composite of a rotated X-ray beam, the image is
always going to appear slightly fuzzy.
− The advantage, a single composite image represents all aspects of a
solder joint. Therefore, one battery of tests can judge the joints integrity.
− One rotation of the x-ray beam is required to create an image.
(In certain circumstances, up to four rotations of the beam can be used to
create a single image.)
• For devices off the focal plane:
− As the beam rotates, it intersects a device that is off the focal plane at
different points.
− These different points form a circle, the diameter defined by the distance
from the focal plane.
− The image is collected from one rotation of the beam. During that
rotation, the device is "smeared" in the corresponding circle and becomes
simply a shadow.
The 5DX allows you to move the panel on the Z Axis to examine devices on the top of
the panel, the bottom of the panel or internal to the panel.
• The deflection angle of the x-ray beam from 28 to 35 degrees.
