Dissipative or conductive materials for intimate contact. ESD protective packaging has been modified further to prevent other sources of static electricity from damaging a packaged item. A Moisture Barrier Bag — click here for more information Determine the type of packaging system that is best suited for the intended application The first step is to choose low charging or static dissipative materials when in contact with ESD sensitive devices.

In addition to these requirements, there are further questions that need to be asked: This site uses cookies.

They may also provide new tools, like voltage retention, or voltage decay, to absi examine complete package configurations. Many companies also require the packaging to protect the contents from a direct discharge or exposure to electric fields.

Air Force Steve Fowler U. Dissipative or Conductive Resistance. 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.

Many manufacturing processes employ a “total factory” approach, where the entire factory is a safeguarded area. Qnsi in the amount of relative motion between the package and contained device will reduce x541 amount of charge accumulated. A class of chemicals called antistats is frequently used to make packaging low charging. Sing-up for Protektive Pak updates!

The impregnated corrugated has a buried shielding layer that provides the shielding ESD control property so that ESD sensitive items can be stored or transported eesd an ESD protected area.

Surface resistance 2-point electrode. Static dissipation is achieved with topically applied antistat. Protection Property Low charging antistatic Materials that have reduced amounts of charge accumulation as compared with standard packaging materials.

Defining ESD Protective Packaging Requirements

Note that the unit of measurement for conductive and for dissipative is surface or volume resistance in ohms; not resistivity. Where this standard does not provide a test method, the user must determine the electrostatic discharge shielding properties of the packaging. A Faraday cage or Faraday shield is an enclosure formed by conducting material or by a mesh of such material.

Users are cautioned that this document cannot replace or supersede any requirements for personnel safety. This distinction is important for packaging considerations because different properties are required to manage essd situation.

If items are susceptible to moisture, a barrier material should be chosen to prevent excessive humidity exposure. Surface resistance of planar materials. Materials that have reduced amounts of charge accumulation as compared with standard packaging materials. Leave a Reply Cancel reply. Compliance Verification of static control packaging properties should be part of the ESD control compliance verification plan. This standard describes the packaging material properties needed to protect electrostatic discharge ESD sensitive electronic items, and references the testing methods for evaluating packaging and packaging materials esf those properties.

Polyethylene bags are useful packages for containing items and providing protection from physical and environmental damage. Dissipative or conductive materials for intimate contact.

DescoEurope – ESD Standards

Making the package less insulative provides a path for charge to ahsi from the package. Materials that have reduced amounts of charge accumulation as compared with standard packaging materials. Upon completion of the evaluation, requirements may be added, modified or deleted.
