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.

I have a QuickTime movie showing it. Werner ************** The year's hottest artists on the red carpet at the Grammy Awards. Go to AOL Music. (http://music.aol.com/grammys?NCID=aolcmp00300000002565)
