NOTE — A material’s antistatic property is not necessarily correlatable with its resistivity or resistance. When more than one ESD worksurface is used at a workstation, each surface shall be individually connected to the ESD ground.
Adding a Data Visualiz When a floor grounding device e. Lines of force surrounding an electrically charged object. Electrical charge at rest.
A source of charged air molecules ions. Use of alligator clips is not recommended. Applying or removing static generating tapes and labels to antistatic tubes, magazines and carriers shall not be done with ESDS devices inside.
The point, electrodes, bus bar, metal strips, or other system of conductors that form a path from a statically charged person or object to ground. When R2 or R3 are used, the resistor values shall be as recommended by the ESD protective equipment manufacturer.
Recommended Weekly a ESD protected workstation. A material having a surface resistivity of at least 1 x ohms per square or volume resistivity of at least 1 x ohm centimeter. During application of any antistatic chemical, the user must consider the following: The intent of this document is for users to incorporate these minimal requirements into their ESD control program to provide a consistent ESD protection level for their products.
A short form of electrostatic. The ionizer shall be aimed at the devices jes6d25 operator’s hands rather than at the operator. NOTE — ESD controlled packing materials that will be inside wafer and die containers should be selected to avoid contamination of the devices.

The wire should be attached to physical structures to prevent mechanical damage. When both equipment and earth grounds are used at the same ESD protective workstation they shall be bonded together at some point in the ground system. NOTE — The electrical charge is due to the transfer of electrons within a body polarization or from one body to another. A resistor in the grounding wire is optional. The entire low-impedance path from jesd652 piece of electrical equipment to a hardground electrode e.
NOTE — Surface resistance is expressed in ohms. As a minimum, the records shall show dates of training, length of training session, topics covered, and the name of the trainer.
The required and recommended ESD item checks are listed in table 2. Equipment ground is the electrical ground green wire at receptacles that have been tested to and jes6d25 the requirements of NFPA or local equivalent. Wire splices should be crimped or soldered. Air velocity measurements are not required. A designated connection, location, or assembly used on an ESD protective material or device that is intended to accommodate electrical connection from the device to ESD ground.
NOTE — A conductive material is not necessarily antistatic.
REQUIREMENTS FOR HANDLING ELECTROSTATIC-DISCHARGE-SENSITIVE (ESDS) DEVICES
Otherwise, the attribute fail must be recorded. The passage of a static charge through an electrostatic-discharge-sensitive ESDS device can result in catastrophic failure or performance degradation of the part. Static Generating Sources and Charged Surfaces 5. Corrective actions resulting from monitor alarms shall be documented. NOTE — The requirements of this standard are not imposed prior to probe. The transfer of electrostatic charge between bodies or surfaces that are at different electrostatic potentials.
An example of an ESD protected package caution label is shown in figure 2. Grounded flooring or floor mats jewd625 only required when personnel or mobile ESD protective workstations utilize floor grounding methods.
