Hi Genny!

Sorry it's taken me a bit to get your picture posted, but I just got
back from 2-weeks vacation and a week in Colorado going to a
IPC-771/7721 instructor certification class, so I've been catching up on
things this morning. But here is your picture:

Myself, I wouldn't worry about them tiny solderballs. They probably
aren't going anywhere, and besides if they did, they're so small what
problem could it cause?

Steve

Have you ever gotten a much better analytical tool available to you, and
have it cause major panic due to what you can see now that you never saw
before?
We got a major fancy dancy brand new X-Ray.
Now we see things like the attached picture.  Steve, could I trouble you
to post it for me?  
 <<solderballs-QFN.jpg>>
Our old X-Ray would have never seen this.
Would you fail these solder balls?

It is a QFN, 0.5mm pitch, 0.3mm pad width with a heat slug.
I think trying to replace this device by hand would cause more trouble
than we see right now.
