When R2 or R3 are used, the resistor values shall be as recommended by the ESD jewd625 equipment manufacturer. Wherever possible, the color red for the symbol should be avoided as red suggests a personnel hazard Reference EIA As a minimum, audit records shall specify what was audited, the auditor’s jesr625, date of audit, audit results, corrective actions required if applicableand evidence of verification of satisfactory completion of any required corrective actions.
REQUIREMENTS FOR HANDLING ELECTROSTATIC-DISCHARGE-SENSITIVE (ESDS) DEVICES | JEDEC
A material having a surface resistivity of at least 1 x ohms per square or volume resistivity of at least 1 x ohm centimeter. Where both grounds are used, they shall be connected bonded together. Otherwise, the attribute fail must be recorded. NOTE — The electrical charge is due to the transfer of electrons within a body polarization or from one body to another. Grounded flooring or floor mats are only required when personnel or mobile ESD protective workstations utilize floor grounding methods.
JESDA ESD Handling Dec, _图文_百度文库
A resistor in the grounding wire is optional. Records shall be maintained for at least two 2 complete years. NOTE — The requirements of this standard are not imposed prior to probe.
Equipment ground is the electrical ground green wire at receptacles that have been tested to jesd6225 meet the requirements jezd625 NFPA or local equivalent. Air velocity measurements are not required. A work position with materials and equipment that limit electrostatic potential.
The generation of electrostatic charges when two pieces of material in intimate contact are separated where one or both is an insulator.
NOTE — A material’s antistatic property is not necessarily correlatable with its resistivity or resistance.
When a floor grounding device e. Corrective actions resulting from monitor alarms shall be documented. NOTE — A conductive material is not necessarily antistatic. No claims to be in conformance with this standard may be made unless all requirements stated in the standard are met.
REQUIREMENTS FOR HANDLING ELECTROSTATIC-DISCHARGE-SENSITIVE (ESDS) DEVICES
The requirements within this standard were derived from existing industry standards, specifications, test methods, and input from various industry reviews. A material having a surface resistance between 1 x ohms and 1 x x or a volume resistivity between 1 x ohm centimeters and 1 x ohm centimeters.
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. A material that has a surface resistivity less z 1x ohms per square or a volume resistivity less than 1x ohm centimeter. A short form of electrostatic. Applying or removing static generating tapes and labels to antistatic tubes, magazines and carriers shall not be done with ESDS devices inside. The wire should be attached to physical structures to prevent mechanical damage.
Lines of force surrounding an electrically charged object. A table top or other surface on which to work that has a resistance to ground of less than ohms ground: During application of any antistatic chemical, the user must consider the following: The transfer of electrostatic charge between jrsd625 or surfaces that are at different electrostatic potentials.
The caution label shall be legible to normal vision at a distance of three feet. When both q and earth grounds are used at the same ESD protective workstation they shall be bonded together at some point in the ground system. 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.
NOTE — ESD controlled packing materials that will be inside wafer and die containers should be selected to avoid contamination of the devices. A packaging jesd652 that provides electrostatic protection and limits triboelectric charging to levels that do not result in device damage. NOTE 1 Volume resistivity is jfsd625 expressed in ohm centimeters.
By downloading this file the individual agrees not to charge or resell the resulting material. Organizations may obtain permission to reproduce a limited number of copies through entering into a license agreement. The ionizer shall be aimed at the devices and operator’s hands rather than at the operator. As a minimum, the records shall show dates of training, length of training session, topics covered, and the name of the trainer.
The dc voltage divided by the current passing between two electrodes of specified configuration that contact the same side of a insulative material or item. Recommended Quarterly ESD protected area and workstation static voltage surveys. Wire splices should be crimped or soldered. Prior to probe, the manufacturer jezd625 take appropriate ESD precautions to minimize damage to devices.
ESD Protective Worksurface 2. The required and recommended ESD item checks are listed in table 2.
However a lower value may be used if local safety requirements can still be met. Static Generating Sources and Charged Surfaces 5. 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.
