ESD (electrostatic discharge) is defined as the transfer of electric charge, which takes place when two objects which have been charged to different electric potentials are brought in contact with one another or when two objects which have different electric potentials due to static induction are brought in contact
Correspondingly, how does ESD cause damage to circuits?
One of the causes of ESD events is static electricity. Static electricity is often generated through tribocharging, the separation of electric charges that occurs when two materials are brought into contact and then separated. Another cause of ESD damage is through electrostatic induction.
What is a ESD control?
A workstation also may be located in a controlled area such as a cleanroom. The key ESD control elements comprising most workstations are a static dissipative worksurface, a means of grounding personnel (usually a wrist strap), a common point ground, and appropriate signage and labeling.
