Separate topic, how was the IPC 7711/7721 training class? Worthwhile? We have been considering it.... Karen H.A.

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: http://stevezeva.homestead.com/files/solderballs-QFN.jpg 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?

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.
