Woody: Consider using test BGA with no chip in, but daisy chains that you can monitor. After soldering, run environmental tests and follow with electrical tests to determine if the product concept is good enough.

Woody, Daisy chain packages are definitely needed, but if you can get packages with a dummy chip inside these will provide a more accurate simulation of working components. If possible, continuous monitoring of resistance during the test will be
