Together, EIA and JESDA detail the ESD requirements from the earliest steps in the assembly process to the final packing, shipping, and handling of. JEDEC. STANDARD. Requirements for Handling Electrostatic-Discharge- Sensitive (ESDS) Devices JESDA (Revision of EIA). DECEMBER charging up to dangerous levels (> 1kV) (JEDEC specification JESDA). Verify that machines and microscopes are properly grounded per JESDA.

During application of any antistatic chemical, the user must consider the following: ESD Protective Worksurface 2. Electrical charge at rest. Applying or removing static generating tapes and labels to antistatic tubes, magazines and carriers shall not be done with ESDS devices inside.
JESDA ESD Handling Dec, _图文_百度文库
When a floor grounding device e. As a minimum, audit records shall specify what was audited, the auditor’s name, date of audit, audit results, corrective actions required if applicable jessd625, and evidence of verification of satisfactory completion of any required corrective actions.
A source of charged air molecules ions. When ESD protective smocks are worn, they shall cover all personal garments above the waist except at the neck area.
The generation of electrostatic charges when two pieces of material in intimate contact are separated where one or both is an insulator. When R2 or Z are used, the resistor values shall be as recommended by the ESD protective equipment manufacturer.
Wire splices should be crimped or soldered. NOTE 1 Volume resistivity is generally expressed in ohm centimeters. Where the choice of color is arbitrary, it is suggested that the symbol be black on a yellow background.
REQUIREMENTS FOR HANDLING ELECTROSTATIC-DISCHARGE-SENSITIVE (ESDS) DEVICES
Recommended Weekly a ESD protected workstation. The wire should be attached to physical structures to prevent mechanical damage.
Adding a Data Visualiz By downloading this file the individual agrees not to charge or resell the resulting material. ESD Protective Smocks 6. 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. Wherever possible, the color red for the symbol should be avoided as red suggests a personnel hazard Reference EIA A packaging system that provides electrostatic protection and limits triboelectric charging to levels that do not result in device damage.
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. The ionizer shall be aimed at the devices and operator’s hands rather than at the operator.

Monochromatic reproduction in any color that contrasts with the background may be used. A resistor in the grounding wire is optional.
A material that has a surface resistivity less than 1x ohms per square or a volume resistivity less than 1x ohm centimeter. Grounded flooring or floor mats are only required when personnel or mobile ESD protective workstations utilize floor grounding methods.
A table top or other surface on which to work that has a resistance to ground of less than ohms ground: The requirements within this standard were derived from existing industry standards, specifications, test methods, and input from various industry reviews. 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.
No claims to be in conformance with this standard may be made unless all requirements stated in the standard are met.
NOTE — A conductive material is not necessarily antistatic. 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. When more than one ESD worksurface is used at a workstation, each surface shall be individually connected to the ESD ground.
