When R2 or R3 are used, the resistor values shall be as recommended by the ESD protective equipment manufacturer. The ionizer shall be aimed at the devices and operator’s hands rather jsed625 at the operator.
JESDA ESD Handling Dec, _图文_百度文库
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. Corrective actions resulting from monitor alarms shall be documented. No claims to be in conformance with this standard may be made unless all requirements stated in the standard are met. NOTE — Substantial generation of static electricity can be caused by contact and separation of two materials or by rubbing two substances together.
Adding jeesd625 Data Visualiz Air velocity measurements are not required. Organizations may obtain permission to reproduce a limited number of copies through entering jessd625 a license agreement.
Wherever possible, the color red for the symbol should be avoided as red suggests a personnel hazard Reference EIA NOTE — A material’s antistatic property is not necessarily correlatable with its resistivity or resistance.
A barrier or enclosure that limits jesd25 penetration of an electrostatic field so that its effects do not reach the stored or contained devices and produce damage.
REQUIREMENTS FOR HANDLING ELECTROSTATIC-DISCHARGE-SENSITIVE (ESDS) DEVICES
Records shall be maintained for at least two 2 complete years. A typical grounding system for an ESD protected workstation is illustrated in figure 1. An example of an ESD protected package caution label is shown in figure 2. The required and recommended ESD item checks are listed in table 2.
Recommended Weekly a ESD protected workstation. A work position with materials and equipment that limit electrostatic potential.
NOTE — A conductive material is not necessarily antistatic. Otherwise, the attribute fail must be recorded. Applying or removing static generating tapes and labels to antistatic tubes, magazines and carriers shall not be done with ESDS devices inside. A packaging system that provides jedd625 protection and limits triboelectric charging to levels that do not result in device damage. NOTE — The requirements of this standard are not imposed prior to probe.
A material having a surface resistance between 1 x ohms and 1 x ohms or a volume resistivity between 1 x jesd6225 centimeters and 1 x ohm centimeters. Its value shall be within the limits specified in table 2, 1.
Prior to probe, the manufacturer should take appropriate ESD precautions to minimize damage to devices. The point, electrodes, bus bar, metal strips, or other system of conductors that form a path from a statically iesd625 person or object to ground.

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. By downloading this file q individual agrees not to charge or resell the resulting material.
As a minimum, the records shall show hesd625 of training, length of training session, topics covered, and the name of the trainer. When ESD protective smocks are worn, they shall cover all personal garments above the waist except at the neck area. 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.
Electrical charge at rest. During application of any antistatic chemical, the user must consider the following: Monochromatic reproduction in any color that contrasts with the background may be used.
The lowest level of ESD that produces changes in device characteristics such that the device fails to meet its specified characteristics. Jesd65 the supplier’s original packing materials and containers are noncompliant to this standard, the Aa devices shall be rejected and returned in the original materials and containers. The entire low-impedance path from a piece of electrical equipment to a hardground electrode e.
When more than one ESD worksurface is used at a workstation, each surface shall be individually connected to the ESD ground. A short form jfsd625 electrostatic. A table top or other surface on which to work that has a resistance to ground of less than ohms ground: ESD Protective Worksurface 2. Lines of force surrounding an electrically charged object.
ESD Protective Smocks 6. A source of charged air molecules ions. The transfer of electrostatic charge between bodies or surfaces that are at different electrostatic potentials.
