Hi Technetters,
Looks like we might have solved our BGA intermittent.  Two boards were
accidently dropped from  a height of 12" (off a tray).  The (4) 1028 ball
BGAs popped off both boards!  What is really interesting is that all the
balls stayed on the boards, not on the device substrate.   Any idea what
would cause this?  I know that you normally need a hammer to get a BGA off
the board (unless you have an SRT).  The device sees about 205 C at peak.

Thanks in advance?
Kerry
