Electrostatic discharge (ESD) is the sudden and momentary electric current that flows between two objects at different electrical potentials caused by direct contact or induced by an electrostatic field. The term is usually used in the electronics and other industries to describe momentary unwanted currents that may cause damage to electronic equipment. ESD is a serious issue in solid state electronics, such asintegrated circuits. Integrated circuits are made fromsemiconductor materials such as silicon and insulating materials such as silicon dioxide. Either of these materials can suffer permanent damage when subjected to high voltages; as a result there are now a number of antistatic devices that help prevent static build up. It is required, especially in the car industry, that components, packaging, work shoes and clothing are ESD rated. One of the most sensitive components is the IC circuit. It is very important that you do not wear a knitted sweater. Static electricity is formed when you take it off. If you then touch a circuit board the sensitive components can be damaged.
