How important is humidity in the control of electrostatic problems?

Q: How important is humidity in the control of electrostatic problems? What is the approximate decrease in electrostatic control if the humidity is reduced from 50% to 35% RH?

A: I have linked a white paper below for your review that puts this topic into perspective.

This data seems most relevant in this case, because it points out how well humidity from 30% and up reduced tribo-charging, but not good enough for the thin-film applications. Notice that voltages of up to 1.5 kV are still generated with ease in an 80% environment! Dropping from 50% to 35% might be beneficial to prevent corrosion, but still require an EPA (ESD PROTECTED AREA) with a total ESD protection system.
