NPFC - MIL-PRF-81705
BARRIER MATERIALS, FLEXIBLE, ELECTROSTATIC DISCHARGE PROTECTIVE, HEAT-SEALABLE
|Publication Date:||8 February 2010|
This specification establishes the requirements for heat-sealable, electrostatic discharge protective, flexible barrier materials used for the military packaging of microcircuits, sensitive semiconductor devices, sensitive resistors, and associated higher assemblies. In addition, the type I materials provide for watervaporproof protection and attenuation of electromagnetic interference effects (see 6.1).

The barrier materials covered by this specification are intended for use in specialized military methods of preservation. The combination of all performance characteristics of MIL-PRF-81705; electromagnetic interference attenuation; electrostatic shielding; static decay; water vapor transmission rate; surface resistivity; waterproofness; transparency; marking abrasion resistance; thickness; aging; seam strength and fabrication; breaking strength; puncture; blocking and curl resistance; contact corrosivity; delamination; water resistance of marking, provides the necessary requirements for protection from exposure to the extremes of the navy/naval aviation environment. Navy/naval aviation items are exposed to high moisture, high salt concentration, transfer at sea, rough handling, and minimal storage conditions. There are no commercial equivalents that meet the physical, mechanical, and corrosion requirements necessary to protect materiel that is exposed to the operational naval aviation environment. Specifically, Specialized Method of Preservation, GX of MIL-STD-2073-1E use MIL-PRF-81705 as the premier source of barrier materials that provide watervaporproof and electrostatic discharge protection for applicable items encountering the above conditions. MIL-PRF-81705 provides the building blocks for applying Electrostatic Discharge Protective techniques approved under MIL-STD-2073-1E.View Less
