The Definition of Electrostatic discharge  (ESD)

Electrostatic discharge (ESD) is the sudden flow of electricity between two electrically charged objects caused by contact, and electrical short, or dielectric breakdown.  A buildup of static electricity can be caused by tribocharging or by electrostatic induction.The ESD occurs when differently-charged objects are brought close together or when the dielectric between them breaks down, often creating a visible spark.

Real life examples of ESD include:

• The static electricity you can feel when you remove your sweat in winter
• Walking across carpet and then touching a metal door handle
• Coming into contact with another person
• When you brush your hear, especially in winter
• Lightning Steel handle on the door close-up

Electrostatic Discharge can damage components and products containing electronics. It is the hidden enemy in many high-tech factories. Often this damage cannot be detected by quality control inspections, and can be very frustrating; adversely impacting productivity, quality, product reliability and thus a company’s reputation and profitability.
