Insulative materials prevent or limit the flow of electrons across their surface or through their volume. Insulative materials have a high electrical resistance and are difficult to ground, thus are not ESD materials. Static charges remain in place on these materials for a very long time.
Symbol for an ESD protection device – EPA Alternate warning symbol Symbol of an ESD grounding point for all components An electrostatic-sensitive device (often abbreviated ESD ) is any component (primarily electrical) which can be damaged by common static charges which build up on people, tools, and other non-conductors or semiconductors . [ 1 ]
An efficient way to prevent ESD is to use materials that are not too conductive but will slowly conduct static charges away. These materials are called static dissipative and have resistivity values below 10 12 ohm-meters. Materials in automated manufacturing which will touch on conductive areas of ESD sensitive electronic should be made of ...
IEC 61000-4-2 is the International Electrotechnical Commission's immunity standard on electrostatic discharge (ESD). The publication is one of the basic EMC standards of the IEC 61000–4 series. The European equivalent of the standard is called EN 61000-4-2. The current version of the IEC standard is the second edition dated 2008-12-09. [1]
An antistatic wrist strap, ESD wrist strap, or ground bracelet is an antistatic device used to safely ground a person working on very sensitive electronic equipment, to prevent the buildup of static electricity on their body, which can result in ESD.
Note the two recurring ESD symbols An antistatic bag is a bag used for storing electronic components, which are prone to damage caused by electrostatic discharge (ESD). These bags are usually plastic polyethylene terephthalate (PET) and have a distinctive color (silvery for metallised film , pink or black for polyethylene ).
ESD (gene), a human gene/enzyme; Electrostatic discharge, a sudden flow of electricity between two electrically charged objects; Electrostatic-sensitive device, any component which can be damaged by common static charges; Energy spectral density, a part of a function in statistical signal processing
Warning label for an electrostatic sensitive device, denoting the devices susceptibility to damage. A similar symbol without the bar and with a black "dome" denotes ESD-safe equipment. The human-body model (HBM) is the most commonly used model for characterizing the susceptibility of an electronic device to damage from electrostatic discharge ...
