Gregg,
Another source of dummy BGAs with daisy chain test patterns and matching
test boards is:
Soldering Technology International Inc

BGAs are definitely moisture sensitive. If they have been out of the
drypack too long, you need to rebake them for 24 hrs at 120 deg C below
50% R.H. (We have found the 50% R.H. not to be a problem because the R.H.
in the oven is a lot lower than in the room.) Edmund Scientific sell a
neat little thermometer/hygrometer that stores min/max values for about
$35.
