Specifically I am wondering about the mechanical strength of the surface mount connections in consumer electronics. Are some tougher than others?
I've had a few experiences where an electronic device (single board computer, intel camera, intel edison), has fallen once from a small height and as a result has become completely useless - doesn't turn on isn't recognized by computer etc.
On the other hand I have dropped my iPhone multiple times, and know lots people who have practically dropped their phones off of buildings, but apart from a shattered screen the phone almost always retains its functionality.
So why is this the case? Do phone companies expect consumers will drop their phones and make them tougher. If so why aren't all devices (cameras,SBC's,etc) made to this standard of toughness?
