What is Electrostatic Discharge (ESD)?

Illustration Example

Electrostatic discharge is the rapid movement of a charge from one object to another object.

As you walk across the carpet, you may not realize that you are generating several thousand volts of electrical charge that will cause severe damage to electronic components or entire circuit card assemblies. This shock, or release of energy, is what is known as Electrostatic Discharge or an ESD Event.

Illustration Example

When your finger comes close to a door knob or your computer screen, you may feel a slight shock.

Sometimes the results of an ESD Event will not show up for weeks or even months in electrical components.

You may not realize it, but every time that you touch an electronic piece of equipment, you may feel nothing, but a sensitive electronic component could either be destroyed or become unstable.
