Air Force Steve Fowler U. The cost of the packaging compared to the total value of the contents is important. In the case of an EPA designed with continuous grounding of all conductors and dissipative items including personnelpackaging may not be necessary. Notify me of new comments via email.

DescoEurope – ESD Standards

They are typically rendered ESD-protective with antistat, carbon, or hygroscopic material. ESD packaging will have special material composition to lower the resistance so that when grounded, electrostatic charges will be removed to ground.

Sing-up for Protektive Pak updates! Mitigation of triboelectrification can be accomplished several ways. Since the electric field must pass through the package, the s51 can be used to shield the device from the electric field.

ed A structure that provides electrostatic discharge shielding. 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.

Guidance for plastic stress w541 can be found in EIA Aesthetic requirements for packaging? However, polyethylene bags accumulate potentially damaging amounts of static electricity.

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.

Static dissipation is achieved with topically applied antistat. The packaging generally retains physical and environmental protective qualities. Conductive bags are extruded plastic combined with conductive materials and exhibit the same properties on both surfaces.

The packaging generally retains its physical and environmental protective qualities.

If items are susceptible to moisture, a barrier material should be chosen to prevent excessive humidity a541. Specific amounts of resistance are useful for different purposes.

Then the device should be evaluated for damage from those ESD threats, while being protected by the proposed level of packaging. A Moisture Barrier Bag — click here for more information.

Dissipative or Conductive Resistance Provides an electrical path for charge to dissipate from the package. ESD Shielding of Bags. A surface conductive material shall have a surface resistance of less than 1. Leave a Reply Cancel reply Enter your comment here The metal body of the aircraft protects the interior. Where this standard does not provide a test method, the user must determine the electrostatic discharge shielding properties of the packaging.

Test the final packaging design for effectiveness It is highly recommended to subject packages to the type of hazards that can be expected during shipments.

The Resistance Classifications are illustrated in Figure 3. Many companies also require the packaging to protect the contents from a direct discharge or exposure to electric fields.

Triboelectrification is usually the charge source. Charge accumulation occurs when two materials are contacted and separated from each other.

Dissipative or conductive materials for intimate contact. In es instances, desiccant should be put inside of the package or the air should be removed from the package before shipment.
