Description / Abstract:

It is intended that these barrier materials be used to fabricate enclosures for electrostatic and/or electromagnetic sensitive equipment and components. These barrier materials are especially formulated to prevent the buildup or retention of electrostatic potential and to protect electronic parts.

Type I barrier material is intended for use for the watervaporproof, electrostatic and electromagnetic protection of microcircuits, certain semiconductor devices (such as microwave diodes and field effect transistors, sensitive resistors and other miniature electronic parts requiring this protection).

Type II barrier material is intended for use where transparency and static dissipation is required and contact with oil or grease is not contemplated. The transparent material is also intended for level C packaging use where a waterproof, static disspative barrier is needed. For level A requirement its use is limited to interior wraps or bags.

Type III barrier material is intended for use where a transparent, waterproof, electrostatic-protective and electrostatic field protective barrier is required. When specified for use with Type I material, provides for enhanced EMI and electrostatic shielding protection. This material is also intended for level C packaging. However, when level A packaging is required, its use is limited to interior wraps or bags.

A class designation has been established in order to distinguish between materials which do, and do not curl. Class 1 material has unlimited use and is suitable for the fabrication of bags by manual sealing methods or by automated bag making machines. Class 2 material is suitable for the fabrication of bags only by automated bag making machines.
