Honored Contributor --- Quote Start --- Well, while this is a little bit off-Topic.. There are also other applications than only space ones requiring -55°C. From my Point of view everyone is more and more focussed on automotive or Extended industrial, both starting at -40°C ;-) --- Quote End --- I got a bit curious and temps less than -40°C are not all that uncommon in Alaska etc. But -55°C requires military grade and many chips are not available in it. https://en.wikipedia.org/wiki/operating_temperature Mechanical reliability of BGA concerns some applications. We've used BGA FPGA's for many years in an board that is subject to 3 or 4 G's a few hundred times and hour with no problem. But it's hardly an extreme case. There are ways to deal with the problem: https://en.wikipedia.org/wiki/ball_grid_array#noncompliant_connections I think he has alot of other issues before he needs to worry about such things though.
