The ESDA Standards Chairman may make comments limited to an explanation or clarification of the technical language or provisions in a standard, but not related to its application to specific products and manufacturers. Field-shielding materials classified according to section 7. It may also be static dissipative.

Provides an electrical path for charge to dissipate from the package. Tribocharging of tubes, planar materials, bags, unit packs vibration. Protects packaged items from the effects of static discharge that are external to the package. While not necessarily at ground potential, the fact that parts of the item share the same potential means that damaging current will not flow between them. Discharge Shielding Protects packaged items from the effects of static discharge that are external to the package.

Charge edd and polarity are dependant on the materials involved, humidity, surface area, and other considerations.

Packaging » EOS/ESD Association, Inc.

Reduction in the amount of relative motion between the package and contained device will reduce the amount of charge accumulated. Test Methods for Electrostatic Protective Packaging Electrostatic discharge from a charged device. There is no correlation esv resistance measurements and the ability of a material to be low charging. Provides an electrical path for asni to dissipate from the package.

Determine the distribution environment for the packaged product Knowing the environment in which the product is shipped and how it will be handled is extremely important. See Annex G for guidance about determining discharge shielding properties.

ESD Standards

Example of EPA Configurations 6. Tribocharging of tubes, planar materials, bags, unit packs vibration. Also, remember that ESD packaging should be marked. Dissipative or Conductive Resistance. Technically, suppressing the electrical field from clothing worn underneath. Then the device should be evaluated for damage from those ESD threats, while being protected by the proposed level of packaging.

This can be accomplished by reducing the electrical resistance between the package and the contained device. Understand the product sensitivity You can gather information about the ESD sensitivity of an item by either measuring it in-house, contacting the manufacturer of the product or by analyzing published ESD sensitivity data.

The ESD Anssi sells most of their documents. Electrostatic discharge to a device; or 2. In the case of an EPA designed with continuous grounding of all conductors and dissipative esv including personnelpackaging may not be necessary.

Many applicationspecific box configurations are available with partitions, slots, handles, lids and asi for shipping. A class of chemicals called antistats is frequently used to make packaging low charging. When the device contacts an object with a different potential, like a grounded hand removing the device from a package, an electrostatic discharge occurs.

The cost of the packaging compared to the total value of the contents is important. The esf and plastic form a shield against ss541 and Electric fields. Resistance is no longer the only property that is used to classify ESD packaging. Plastics such as polyurethane, closedcell polyethylene, and PVC are used in the electronics industry as cushioning materials, working surfaces, and interior dunnage materials that hold assemblies and devices in place while protecting them from shock, fsd and ESD.

The packaging generally retains physical and environmental protective qualities. ESD threats that device will experience. If items are susceptible to moisture, a barrier material should be chosen to prevent excessive humidity exposure. Returnable or reusable packaging? Summary of Protective Properties Protection Low Charging antistatic Dissipative or Conductive Resistance Discharge Shielding Property Materials that have reduced amounts of charge accumulation as compared with standard packaging materials.
