SafetyTac™ FREE GUIDE TO ESD and Floor marking
Electrostatic Discharge, or ESD, is a single-event, rapid transfer of electrostatic charge between two objects, usually resulting when two objects at different potentials come into direct contact with each other. ESD can also occur when a high electrostatic field develops between two objects in close proximity. ESD is one of the major causes of device failures in the semiconductor industry.
Electrostatic charge build-up occurs as a result of an imbalance of electrons on the surface of a material. Such a charge build-up develops an electric field that has measurable effects on other objects at a distance. The process of electron transfer as a result of two objects coming into contact with each other and then separating is known as 'triboelectric charging'.
