Electrostatic Discharge (ESD) is the swift transfer of charges between bodies at different potentials. This commonly occurs after the accumulation of static electricity and can negative effects on solid-state electronics.

Sources Of This Phenomenon

Both insulators and conductors are sources of ESD. All materials are defined on the triboelectric series as either positive or negative, with positive and negative charges usually accumulating on naturally occurring surfaces and on synthetic materials respectively. Sparks and lightning are visible Electrostatic Discharge events, the total amount of charge that can accumulate on a material depends on how well it can store charge, but it is still common for static charges to accumulate on people and clothing without in environments where sensitive electronic equipment must be protected, but workers may not notice.

Causes Of Electrostatic Discharge

Electrostatic Discharge can be caused by an electrical breakdown, a short circuit, and most commonly, contact or near contact, due to tribocharging. Tribocharging is the separation of electric charges that occurs when objects make contact and then are separated. ESD is measured using an electrostatic voltmeter.

Its Effect On Electronic Circuits

ESD events like a spark from a human hand allow current to travel to the ground through electronic devices burning holes in integrated circuits and dealing heat damage to the circuit board. This can happen when working barehanded (without an electrostatic wrist strap) with circuit boards and other sensitive electronic equipment, when negatively charged synthetic materials are on or near sensitive electronic equipment, or due to the fast movement of air near electronic equipment.
