Shock limits for electronic components
Shock limits for electronic components
(OP)
hi,
Just had a small question, I am hoping that someone here has come across this. Is there some kind of a shock / vibration frequency limit for electronics? Can we find a value like that in a spec for a device/component? And also if its a generic kind of value for all electronics (e.g. above 20g's and 1000Hz vibration frequency component x will fail) or a place where we can find such numbers?
I am actually looking at putting togather a spec for RFID tags on drill pipes which would withstand high freq. shocks. If anyone has any ideas on how to test this scenario it would be great.
Thanks,

RE: Shock limits for electronic components
But first, you need to determine the level of shock you need to survive, then design around that. Most military electronics can easily survive 20 g and operate afterwards (MIL-STD-810F). Critical electronics on military ships are designed to survive, and possible operate through, shocks above 300 g's (MIL-S-901D)

After a little more discussion with our engineers I found that definition of a shock can also be taken different ways for calculating a damage curve of a component. number cylces, g's, duration all matter. Do you know if the MIL-S-901D accounts for the other variables also?
Thanks,

MIL-S-901D is intended for a single shock, or a few shocks, environment. It's not expected that a ship will be under continual attack for very long, without either winning or getting sunk.
