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.

By placing a conductive shunt across device leads or card connectors, the various parts of the item share the same electrical potential. The user can use these tests to determine the location i. If rigorous handling is expected, cushioned packaging may need to be considered. Both documents were prepared by the Users are cautioned that this document cannot replace or supersede any requirements for personnel safety.
Example of EPA Configurations Returnable or reusable packaging? Since the discharge must pass through the package to reach the device, the package ani be used to protect the device from the ESD event. In the case of an EPA designed with continuous grounding of all conductors and dissipative items including personnelpackaging may not be necessary.
In addition to these d541, there are further questions that need to be asked: Provides an electrical path for charge to dissipate from the package. Surface resistance 2-point electrode. When possible, testing should be performed on the finished package.

Boxes made from paper products are assembled by folding, stapling or gluing. Plastic boxes are injection molded or thermoformed. In addition to these guidelines, there may be additional factors s51 should be considered, e.

To find out more, including how to control cookies, see here: We offer a complete line of ESD Packaging products for transporting, storing and shipping of static sensitive assemblies. Determine the distribution ansii for the packaged product Knowing the environment in which the product is shipped and how it will be handled is extremely important.
Dissipative or conductive materials for intimate contact. Sorry, your blog cannot share posts by email. Sing-up for Protektive Pak updates! By modifying the package interior, the amount of tribocharging can be controlled, and any residual charge can be dissipated evenly throughout the package surface.
Many companies also require the packaging to protect the contents from a direct discharge or exposure to electric fields. Plastic carrier tape is thermoformed and paper carrier tape is die cut. Fill in your details below or click an icon to log in: Nor shall the fact that a standard or publication is published by the Association preclude its voluntary use by non-members of the Association whether the document is to be used either domestically or internationally.
They are typically rendered ESD-protective with antistat, carbon, or hygroscopic material. Create a free website or blog at WordPress. 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.
This includes packaging such as bags, boxes paperboard and plasticsemi-rigid plastic trays, cushion wrap, foam, loose fill, d541, trays, tubes, tape and reel, shrink-wrap, and ans. This shielding bag is low charging, and shields packaged items from ESD and the electric field generated by other items. These tests can, for example, involve the following: Leave a Reply Cancel reply Enter your comment here When the device contacts an object with a different potential, like a grounded hand removing the device from a package, an electrostatic discharge occurs.
Where this standard does not provide a test method, the user must determine the electrostatic discharge shielding properties of the packaging. Dissipative or Conductive Resistance. This reduces charge generation through like material contact and separation.
Defining ESD Protective Packaging Requirements
Protektive Pak Impregnated Corrugated Box with lid. Design a packaging system Once the ESD sensitivity and distribution environment have been evaluated and available materials have been selected, the design of the packaging system can begin.
The carrier tape is wound on a reel similar to motion picture film.
