Electronics can be extremely resilient to vibration and g forces. Self guided artillery shells such as the M982 Excalibur include fairly normal electronics for GPS guidance. https://en.wikipedia.org/wiki/M982_Excalibur
replyOn the ground vibration testing is a standard part of pre-launch spacecraft testing. This would trigger most (not all) vibration/G-force related failures on the ground rather than at the actual launch.
replyThe big question mark is how many failures you cause and catch on the first cycle and how much you're just putting extra wear on the components that pass the test the first time and don't get replaced.
