experience ESD (Electrostatic Discharge) events every day.
Opposites attract, and positive and negative ions are no exception.
ESD events occur when any two objects with dissimilar electrostatic
potential (positive/negative) come into close proximity to each
Whether the ESD event is a tree struck by lightning
or the discharge of a triboelectrically generated charge onto
a single circuit board device, the net effect is much the same.Damages
can and often do occur. It's all proportional.
As a non-profit organization dedicated to a better
understanding of the impact of static electricity on the electronics
industry, the EOS/ESD Association (www.esda.org)
published a series of classifications in 1993 to define the level
of voltage sensitivity of circuit pack technologies.
All Class 1x devices (which are used in many high
technology applications) were defined as having voltage sensitivity
ranges lower than 2,000 volts.
Given that the lowest static charge that a human
can feel is 2,500 volts, damages from electrostatic discharge
can occur to Class 1x technologies without the handler being physically
aware that a static event ever took place.
electricity cannot be eliminated, it can only be controlled.
