ESD precautionary procedures.
The minimum content of an ESD precautionary procedure training should include an
introduction to the physics of electrostatic charge, the voltage levels that can occur in normal
practice and the damage that can be done to electronic components if they are touched by an
operator who is electrostatically charged. Further, an explanation should be given of methods
to prevent build-up of electrostatic charge, and how and why to discharge one's body to earth
or to the frame of the equipment.
