Device
A device is the product being processed by AHE (e.g., an integrated circuit [IC] or a printed circuit [PC] board).
FAQ Category: ESD Terminology
Decay time
Decay time is the time required for an electrostatic potential to be reduced to a given percentage (usually 10%) of its initial value.
Decay rate
Decay rate is the decrease of charge or voltage per unit time.
Corona
Corona is the production of positive and negative ions by a very localised high electric field. The field is normally established by applying a high voltage to a conductor in the shape of a sharp point or wire.
Conductivity
Conductivity is the ratio of the current per unit area (current density) to the electric field in a material. Conductivity is expressed in units of siemens/meter. In non-technical usage, conductivity is the ability to conduct current.
Conductive
The term “conductive” refers to the ability of a material to conduct a charge to ground; low resistance (i.e. less than 1 meg-ohm (10^(6)) – the closer to 1 meg-ohm, the slower the discharge.)
Conductive material
A conductive material is a material that has either a surface resistance of less than 1 x 104 ohms or a volume resistance of less than 1 x 104 ohms or a surface resistivity less than 1 x 105 ohms/square or a volume resistivity less than 1 x 104 ohm-cm. Note: “conductive flooring material” is not […]
Conductive flooring material
Conductive flooring material is a floor material that has a resistance to ground of less than 1.0 x 106 ohms. The term ‘conductive’ or ‘conductivity’ does not guarantee low charge generation. To prevent static charge and ESD damage to static sensitive components, flooring materials must measure in the required resistance range and either be used […]
Component failure
Component failure is a condition in which a tested component does not meet one or more specified static or dynamic data sheet parameters.
Component
A component is an active or passive item such as a resistor, diode, transistor, integrated circuit, or hybrid circuit.
