We are considering sites for a new plant. One of the candidates is about
100m from a railway line. It is the mainline across the country and has very
high traffic.  We have recieved a vibration study of the property but are
not sure how much impact this will have on production processes. Is there
any level of vibration that is known to affect smt processes ,through hole,
wave soldering, microscope use?

peak particle velocities were measured at 0.045 in/sec , and   0.005in/sec
background vibration levels.

I have a table that indicates >0.01 as slightly perceptible to humans ,
>0.025 distinctly perceptible to humans.

Any experiences or input would be appreciated, we don't usually have to
worry about these things on the prairies.
