Hi Werner,


Just to be exact, I didn't say the technique can't see any cracks in solder joints, but razor-like ones (or almost non-opened). :-)

If it's a relatively wide open, then it's possible. I even have a picture of my own. The crack was wide open and I could see it with a Dage nanofocus machine. But I'd like to see the movie too.

Regards,

Vladimir

Hi Vladimir,
What you said is true for most X-ray equipment—and it is also true in practical terms. however, you can see solder joint fractures with X-ray if you focus on a single solder joint [not very practical] and look at it by rotating this SJ.
I have a QuickTime movie showing it.
