One method utilized by static eliminators to apply voltage to needle-shaped electrodes.
A system in which alternating current
(AC) voltage is applied to a needle-shaped electrode.
An abbreviation of "Charged Device Model."
A model in which the charge of the device itself is
the cause of electrostatic breakdown.
The concentration of an electric field in a needle-shaped electrode creates a discharge brought on by the ionization of gas surrounding the electrode. However, the conditions are insufficient to cause a complete electrical breakdown or arcing.
As a charged object draws closer to another charged object, they are either attracted to or repelled from each other. The polarity and amount of charge for each object, as well as the distance between the objects, determines the strength. This electrical interaction between charged particles is called Coulombic force.
A phenomenon in which discharge occurs along an insulating surface.
This occurs as a result of a
localized discharge, such as the discharge created when a charged object is close to a grounded conductor.
One method utilized by static eliminators to apply voltage to needle-shaped electrodes.
A system that applies + or - direct current (DC) voltage to needle-shaped electrodes.
A phenomenon in which a charged object, upon being brought close to a conductor, draws electrical charges of the opposite polarity to the side closest to the charged object.
Breakdown and deterioration of electronic components caused by electrostatic discharge.
EOS, or Electrical Overstress, is defined by an unusual spike in voltage that causes damage, rendering system or component failure. The event usually lasts from microseconds to seconds (short pulses range in the nanoseconds).
An abbreviation of an "ESD Protected Area."
An EPA is an area where ESD-sensitive devices will be handled. Every EPA must be identified and adequately protected by ESD controls to allowable levels.

An abbreviation of "Electrostatic Discharge."
A transfer of electrostatic charges between bodies at different electrostatic potentials caused by direct contact or induced by an electrostatic field.
An abbreviation for "Electrostatic Discharge Sensitive Devices."
Devices that have the possibility of
suffering electrostatic breakdown.
An abbreviation of "Human Body Model."
A model in which a human body charged with static electricity,
upon touching an electronic component such as an IC, will release a discharge and cause electrostatic breakdown.
One type of voltage application system used by static removal devices.
A system in which high-frequency
(number 十 kV), alternating current (AC) voltage is applied to an needle-shaped electrode.
An abbreviation of " Ion Current Control."
A function integrated into a static removal device that senses the amount of ions being produced. This function also senses the polarity and strength of charged objects. By sensing these variables, the static removal device then automatically adjusts the ion balance to supply ions that best respond to the charged object.
This is a KEYENCE original control system.
An abbreviation of "International Electrotechinical Commission", an international standardization agency for the electrical and electronic field.
An abbreviation of "Machine Model."
A model in which equipment charged with static
electricity, upon touching an electronic component such as an IC, will release a discharge and cause electrostatic breakdown.
One method utilized by static eliminators to apply voltage to needle-shaped electrodes.
A system in which both + and - voltage is alternately applied to a single needle-shaped electrode.
With the Pulse DC System, the needle-shaped electrode that emits either + or - ions is predetermined. With the Pulse AC System, both + and - ions are alternately produced from a single electrode.
One method utilized by static eliminators to apply voltage to needle-shaped electrodes.
The system consists of a pair of needle-shaped electrodes to which only + or - DC voltage is applied. These negative or positive electrodes then produce only + or ? ions respectively.
An abbreviation of "Semiconductor Equipment and Materials International", the international
association of semiconductor equipment and materials manufacturers.
Their purpose is to unify
international industry standards for the semiconductor industry, which produces items such as semiconductors,
FPD, and solar generators.
The standards set by SEMI are called SEMI standards.
Electricity involving the imbalanced charge present on an object that is typically of sufficient magnitude to produce a spark. This charge is normally created through contact or friction between two charges.
A charge distribution of static electricity charged on the surface of objects such as film.
Though normally invisible, it can become viewable by spraying on a charged 2-color toner.
