What does X-ray inspection of hidden
BGA solder joints reveal? An X-ray image is generated by different X-radiation
absorption of various parts of the object. Simply spoken, these
absorption differences are due to variations in density or thickness
of the object.
For solder joints, mainly the thickness (or shape) is of interest.
The longer the path of the radiation through a part of the object,
the darker this part appears in the image.
