Surface Resistivity: Values obtained for this property depend on electrode configuration, pressure on the electrodes, roughness of the surface being measured, applied voltage, and other factors, so that methods of measurement are a deep subject (Ref. 4-19). However, for our purposes, an approximate, easily made determination by a Voyager SRM-II 0 meter or equivalent is sufficient. The critical property is bleed-off time for static charges and, since we don't have an exact criterion for bleed-off time, which is arbitrary, we don't need precise values for the property, surface resistivity, that controls bleed-off time.

Grounding also means the electrical connection of conductive, static-dissipative, or antistatic materials with earth in any manner. HBM: Human Body Model, a damage mechanism (special case of DI). , to 30% or 40% minimum at 70°F, to reduce the triboelectric charging of materials in the SSW. Insulator: A nonconductor. Ionization: The ionization of air for the purpose of neutralizing charged surfaces. Latent Failure: Failure of an ESDS device because of previous degradation and weakening by one or more ESD events.

Capacitance: The capacity or ability of an object to hold a charge. In ESD control, the usual unit of capacitance is the picofarad, pF. CDM: Charged Device Model, a damage mechanism. CD Rule: Charge-distance rule. An empirical relation of safe distance from a surface versus the apparent charge on that surface. This rule protects items sensitive to 100 V from damage by E fields by the FIM. Conductive: Having a surface resistivity of less than lOS ohms/square. Conductor: A conductive material. Common examples in ESD control are metals and plastics loaded with graphitic ("metallic") carbon.
