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.
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.
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 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.
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.
Graphics represented as a rectangular grid of pixels. Rasterization Converting vector graphics to raster graphics. This terms also denotes a common method of rendering 3D models in real time. Ray casting Rendering by casting non-recursive rays from the camera into the scene. 2D ray casting is a 2.5D rendering method. Ray marching
A compound semiconductor is a semiconductor compound composed of chemical elements of at least two different species. These semiconductors form for example in periodic table groups 13–15 (old groups III–V), for example of elements from the Boron group (old group III, boron, aluminium, gallium, indium) and from group 15 (old group V, nitrogen, phosphorus, arsenic, antimony, bismuth).
An electrostatic plotter is a type of plotter that draws images on paper with an electrostatic process. They are most frequently used for Computer-Aided Engineering (CAE), producing raster images via either a Liquid Toner or a Dry Toner model. Liquid Toner models use toner that is positively charged and thus becomes attracted to paper's ...
