Good day all,

I have a question relative to solder balls and hope that someone can
shed some light on this issue.

1.  What causes solder balls?
2.  Could solder balls be the result of incompatiability between flux
and soldermask?
3.  How do you eliminate solder balls?
4.  What is the IPC acceptability standards for solder balls?

Any feedback would be greatly appreciated.  Thanks to all that offer
assistance.

Best Regards
