I agree.
James, if you review VT-54 Electrostatic Discharge control for operators (IPC
video training) and the instruction/test there in, you can not rely on Humidity
to control ESD damage.

James, I think it would be a bad practice
not to use ESD smocks. ESD is a surface phenomenon and although higher humidity
lessens static generation and build-up it does not reduce it enough to abandon
other ESD safeguards.

Subject: [TN] ESD ISSUE
Good day Technetters:
I need some opinions (this may be asking
for trouble!). Located in the
north east, temperature/humidity levels can change on a daily
basis. It has
been our policy that, during summer months when the humidity is
high, the
operators do not have to wear ESD smocks in areas that are not air
conditioned. There is no hard fast rule as to what the
conditions shall be,
except that a decision is made (by yours truly) that smocks are
optional
when conditions are uncomfortable. I'm trying to select a
specific humidity
level to use as a criteria for the mandatory wearing of
smocks. I
understand that not wearing ESD smocks poses a risk, but the risk
is
minimized during high humidity conditions. What do you think
of this
policy? Any recommendations on a humidity level?
Thanks,
Jim Marsico
