ANSI/ESD S – Hard Copy. ESD Association Standard for the Protection of Electrostatic Discharge Susceptible Items – Packaging Materials. ANSI/ESD S Packaging Materials for ESD Sensitive Items. Posts about ANSI/ESD S written by Desco. Antistatic is the ESD control property properly referred to as “low charging”. This is an important property for all.

Other constructions are e541 for bags. 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. Posted by Protektive Pak. Volume resistance of planar materials. 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 for those properties.
Summary of Protective Properties Other standard packaging including paper corrugate and plastic boxes, trays, and clamshells have, or ss541 presently, following similar paths. Forms include polystyrene or soybean foam pellets, paper, and air filled bladders. Guidance for plastic stress crazing can be esf in EIA Resistance is no longer the only property that is used to classify ESD packaging.
ESD protective packaging has been modified further to prevent other sources of static electricity from damaging a packaged item.

Anssi choice of plastic and ESD treatment determines heat tolerance. Making the package less insulative provides a path for charge to dissipate from the package. Since the discharge must pass through the package to reach the device, the package can be used to protect the device from the ESD event.
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, vibration and ESD. Reduction in the amount of relative motion between the package and contained device will reduce the amount of charge accumulated.
An impressive demonstration of the Faraday cage effect is that of an aircraft being struck by lightning. Performance limits are provided. These considerations could include chemical corrosion, plastic stress crazing, and contamination from outgassing, particulate matter, or moisture.
In addition to these guidelines, there may be additional factors that should be considered, e. For further information, please visit our website at www. For the observation to be valid, the sample must be planar, homogeneous, and electrically dissipative conductive enough to accept the initial 5, volt charge, but not so conductive that the electric field collapses when the sample is grounded.
ESD packaging that offers other protective properties is usually used in conjunction with shunting devices. When possible, testing should be performed on the finished package.
The ESD Association sells most of their documents. Dissipative or Conductive Resistance. Each area has the recommended ESD packaging material properties noted.
Discharge Shielding Protects packaged items from the effects of static discharge that are external to the package. See Annex B for device damage information. 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 esc in contact with ESD sensitive devices.
ESD protective packaging has been modified further to prevent other sources of static electricity from damaging a packaged item. The user can use these tests to determine the location i.
Since the electric field must pass through the package, the package can be used to shield the device from the electric field. There are standard tests measuring the energy penetration of electrostatic discharges to the interior.
