Vibration Standard Required

I need a vibration standard to test component/solder failure on a circuit board that is used in a controller for commercial/industrial applications. Currently, the test that is being advised is a sine test, 10-57Hz, .35mm amplitude and 57-150Hz at 5G (no standard given). I think that this is probably too extreme and I also think that the test should probably be a random test instead of sine since we are trying to simulate standard transportation and vibration levels encountered during field service.<br>Thanks.<br>

A good reference for electrical component testing is:<br><br>NAVMAT P-9492, Navy Manufacturing Screening Program, Department of Navy, May 1979.<br><br>This reference specifies a random vibration test.&nbsp;&nbsp;The purpose of the test is to screen for latent defects such as bad solder joints, intermittent shorts, bad parts, etc.<br><br>You can download a copy of this reference from:<br><br><A HREF="

A word of caution - This is a good STARTING point, but screens are developmental.&nbsp;&nbsp;That is - if you get too many failures, or not enough, you need to lower, raise, or notch the spectrum.&nbsp;&nbsp;A bit of folklore - when this spec first came out in the 80's the profile was called &quot;the Willoughby spec&quot;.
