Protection Property Low charging antistatic Materials that e541 reduced amounts of charge accumulation as compared with standard packaging materials. Surface resistance of planar materials. While most types of packaging not for static sensitive items provide physical and environmental protection, it also may harm static sensitive electronic items by allowing the accumulation or the discharge of static electricity.

This happens frequently, but does not harm the plane or passengers.

Charge accumulation occurs when two materials are contacted and separated from each other. This can be accomplished by reducing the electrical resistance between the package and the contained device.

Volume resistance of planar materials. ESD packaging will have special material composition to lower the resistance so that when grounded, electrostatic charges will be removed to ground thus protecting your ESD a541 devices inside.

Reduction in the amount d541 relative motion between the package and contained device will reduce the amount of charge accumulated. Specific amounts of resistance are useful for different purposes.

Sing-up for Protektive Pak updates! In addition to these requirements, there are further questions that need to be asked: Consider the source of the static electricity and then the path the charge must travel to damage the device. 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.


A structure that provides electrostatic discharge shielding.

Determine the distribution environment for the packaged product Knowing the environment in which the ssd is shipped and how it will be handled is extremely important. Since the electric field must pass through the package, the package can be used to shield the device from the electric field.

Tribocharging of tubes, planar materials, bags, unit packs vibration. The choice of plastic and ESD treatment determines heat tolerance.

Dissipative bags are extruded plastic combined with or coated with chemical antistat, and exhibit the same s41 on both surfaces. Many companies also require the packaging to protect the contents from a direct discharge or exposure to electric fields. A Faraday cage or Faraday shield is an enclosure formed by conducting material or by a mesh of such material. Example of EPA Configurations 6. This layout shows an “islands of protection” approach to ESD safeguards. Chemicals antistats are added to the polyethylene bag to render it low charging.


Dissipative or Conductive Resistance. The packaging generally retains its physical and environmental protective qualities. Electrostatic discharge to a device; or 2. Care should be exercised to neutralize charge on devices prior to shunting to avoid charged device model CDM damage.

The user can use these tests to determine the location i. Note that the unit of measurement for conductive and for dissipative is surface or volume resistance in anssi not resistivity.

ESD Standards

Other standard packaging including paper corrugate and plastic boxes, trays, and clamshells have, or are presently, following similar paths.

Field-shielding materials classified according to section 7. Humidity and temperature are the main factors to consider when it comes to choosing the right type of packaging for your ESD sensitive items. In addition to these guidelines, there may be additional factors that should be considered, e.

Esdd films may be used to bind together multiple items for bulk packages, and may be used to package non-sensitive items, which are used in ESD safe areas, replacing static generating over wraps.
