Equipment ground is the electrical ground green wire at receptacles that have been tested to and meet the requirements of NFPA or local equivalent.
REQUIREMENTS FOR HANDLING ELECTROSTATIC-DISCHARGE-SENSITIVE (ESDS) DEVICES | JEDEC
The dc voltage divided by the current passing between two electrodes of specified configuration that mesd625 the same side of a insulative material or item. NOTE — Topically treated tubes, trays, magazines and carriers tend to lose their static protective properties with use and should be evaluated periodically for acceptable performance.
Wire splices should be crimped or soldered. Static Generating Sources and Charged Surfaces 5. By downloading this file the individual agrees not to charge or resell the resulting material.
NOTE — Substantial generation of static electricity can be caused by contact and separation of two aa or by rubbing two substances together.

As a minimum, audit records shall specify what was audited, the auditor’s name, date of audit, audit results, corrective actions required if applicableand evidence of verification of satisfactory completion of any required corrective actions.
The wire should be attached to physical structures to prevent mechanical damage. When ESD protective smocks are worn, they shall cover all personal garments above the waist except at the neck area.
A packaging system that provides electrostatic protection and limits triboelectric charging to levels that do not result in device damage. A barrier or enclosure that limits the penetration of an electrostatic field so that its effects do not reach the stored or contained devices and produce damage. Where the choice of color is arbitrary, it is suggested that the symbol be black on a yellow background.
When a floor grounding device e. An example of an ESD protected package caution label is shown in figure 2. Adding a Data Visualiz Jsed625 source of charged air molecules ions. The generation of electrostatic charges when two pieces of material in intimate contact are separated where one jjesd625 both is an insulator.
REQUIREMENTS FOR HANDLING ELECTROSTATIC-DISCHARGE-SENSITIVE (ESDS) DEVICES
Otherwise, the attribute fail must be recorded. Recommended Weekly a ESD protected workstation. ESD Protective Worksurface 2. The ionizer shall be aimed at the devices and operator’s hands rather than at the operator. A short form of electrostatic. 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. The entire low-impedance path from a piece of electrical equipment to a hardground electrode e. A work position with materials and equipment that limit electrostatic potential. Applying or removing static generating tapes and labels to antistatic tubes, magazines and carriers shall not be done with ESDS devices inside.
NOTE — A material’s nesd625 property is not necessarily correlatable with its resistivity or resistance.
NOTE — ESD controlled packing materials that will be inside wafer and die containers should be selected to avoid contamination of the devices. Lines of force surrounding an electrically charged object. Air velocity measurements are not required. Wherever possible, the color red for the symbol should be avoided as red suggests a personnel hazard Reference EIA The transfer of jesd6625 charge between bodies or surfaces that are at different electrostatic potentials.
Those with mid-to-lower resistance values provide shorter charge dissipation times. The lowest level of ESD that produces changes in device characteristics such that the device fails to meet its specified characteristics. A typical grounding system for an ESD protected workstation is illustrated in figure 1. NOTE 1 Volume resistivity is generally expressed in ohm centimeters. Use of alligator clips is not recommended.
Monochromatic reproduction in any color that contrasts with the background may be used. Prior to probe, the manufacturer should take appropriate ESD precautions to minimize damage to devices.
Grounded flooring or floor mats are only required when personnel or mobile ESD protective workstations utilize floor grounding methods. When the supplier’s original packing materials and containers are noncompliant to this standard, the ESDS devices shall be rejected and returned in the original materials and containers. NOTE — The requirements of this standard are not imposed prior to probe.
ESD Protective Smocks 6. The ESD caution label on the package may be provided by a preprinted marking on the package or its sealing tape. 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.
Referring to the property of material that inhibits triboelectric charging.
