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.
Examples are computer CPUs, graphics ICs. Computer cards; TTL chips; Laser diodes; Blue light-emitting diodes (LEDs) High precision resistors; The notion of a symbol for an ESD protection device came about in response to the increased usage and failures of static sensitive components by then the computer systems manufacturer, Sperry Univac.
Electrostatic discharge (ESD) is a sudden and momentary flow of electric current between two differently-charged objects when brought close together or when the dielectric between them breaks down, often creating a visible spark associated with the static electricity between the objects.
A network card inside an antistatic bag. A pink static dissipative bag, and a silver conductive bag. 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).
An antistatic device is any device that reduces, dampens, or otherwise inhibits electrostatic discharge, or ESD, which is the buildup or discharge of static electricity. [ 1 ] [ 2 ] ESD can damage electrical components such as computer hard drives, and even ignite flammable liquids and gases.
Computer Graphics: Principles and Practice is a textbook written by James D. Foley, Andries van Dam, Steven K. Feiner, John Hughes, Morgan McGuire, David F. Sklar, and Kurt Akeley and published by Addison–Wesley.
The spacing of the wires controls the resolution of the plotter; for example, 100 or 400 wires to the inch. Dry Toner models use a process similar to xerography in photocopiers . Unlike a laser printer or photocopier , there is no transfer drum used in most electrostatic plotters; the imaging paper is directly exposed to the charging electrode ...
The Nintendo DS, an example of a handheld game console with a resistive touchscreen. A resistive touchscreen is a type of touch-sensitive display that works by detecting pressure applied to the screen. [2] It is composed of two flexible sheets coated with a resistive material and separated by an air gap or microdots. [3]
