Gregg, Another source of dummy BGAs with daisy chain test patterns and matching test boards is: Soldering Technology International Inc Tel (205)461-9191 Fax(205)461-9566 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.
