For many topical staticides (on IC tubes and containers) to function,
the RH must be < 25%.

Hi Rich:
thanks for your reply. Now I regret to say that I am a bit confused.

I must admit I am also confused. It is a fairly common practice and has
proved
quite effective to install humidifiers in enclosed environments to reduce
the
propensity for static electricity generation. Why does this work?

Hi
A 5 kV peak voltage between needle points will produce a spark 0.42
centimeters.
See "Handbook of Chemistry and Physics" under "Spark-Gap Voltages".
There is a table for spark gap distance versus voltage and electrode
shape. There are also corrections for temperature and pressure.
The work
spherical
electrodes. What applies is Paschen's law, which gives the voltage as a
function of distance x atmospheric
pressure.
Have fun!

Hi Allen:
The voltage breakdown of air is presented in
IEC 664.
There is no fixed number (i.e., mm/kV) that
describes or predicts voltage breakdown of air.
The principle factor that affects voltage
breakdown is the shape of the electrodes
(degree of homogeneousness of the electric
I remember seeing a figure for voltage breakdown through air recently, but
can't remember what it is. Seems like it's 1mm per 1000 volts or something
like that. Can anyone help? Specifically, I'm concerned about how much
spacing is required between components and chassis t
