Abstract

Disclosed is an insert for packaging components which are susceptible to damage by Electrostatic Discharge. The insert is flexible and can be fitted either inside or outside conventional rigid packaging containers such as cardboard boxes and the like. In use, the insert provides "Faraday cage" protection of components contained therein from ESD during assembly, transit and field storage.

Packaging for Electrostatic Discharge Sensitive Parts

      Disclosed is an insert for packaging components which are
susceptible to damage by Electrostatic Discharge.  The insert is
flexible and can be fitted either inside or outside conventional
rigid packaging containers such as cardboard boxes and the like.  In
use, the insert provides "Faraday cage" protection of components
contained therein from ESD during assembly, transit and field
storage.

      Referring to the Figures, in a preferred embodiment, the insert
is in the form of an envelope of a flexible metal or metallised
laminate material.  The envelope is shaped and dimensioned to be
received in or accept a conventional cuboid cardboard box.
Preferably, the insert is placed within the box to prevent the
laminate material from becoming damaged during transit.  One end of
the envelope is permanently sealed.  Sealing of the other end of the
envelope is achieved by folding and attaching a re-sealable adhesive
ESD label.  The shape, size and degree of foldover depends on the
geometry and bulk of the component to be protected.  The resealable
label allows the insert to be used more than once.

      The flexible laminate material is preferably formed from a 23
micron layer of aluminium metallised polyester disposed between an
outer layer of antistatic, abrasion-resistant lacquer and an 65
micron inner layer of antistatic polyethylene.  This material
provides 99% attenuation in electrostatic shieldin...
