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.
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.
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.
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).
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]
The price of graphics hardware varies with its power and speed. Most high-end gaming hardware are dedicated graphics cards that cost from $200 up to the price of a new computer. In the graphics cards department, using integrated chips is much cheaper than buying a dedicated card, however the performance conforms to the price.
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 ...
