This test specifies requirements for heat sealable, electrostatic shielding, flexible barrier materials used for military packaging of microcircuits, precision semiconductor devices, precision resistors and related higher assemblies. In addition
Type I materials provide water vapor resistant shielding and attenuation of electromagnetic radiation.
MIL-PRF-81705 Barrier materials provided under the scope of the contract will be products authorized by the qualification activity to be listed in the valid qualified products list before the contract is signed.
Material. Barrier materials shall be made of such materials to ensure compliance with the performance requirements of this specification.
Structure. Barrier materials should be constructed of one or more layers in any shape that ensures compliance with the performance requirements of this specification.
Type I. Type I component materials or finished product are not allowed to be edged except in the direction perpendicular to the rolling direction. When a butt weld is made on the finished product or any solid, the areas will be marked externally with color markers.
prevent that part of the roll from being used.
Type I - Water vapor resistant, electrostatic shielding, electrostatic and electromagnetic shielding.
Type II. Type II barrier material shall be transparent, clear or colored in any colour. The appearance will be the same throughout the material. Materials, talc or other powdery substances shall not be applied to surfaces.
Type II - Transparent, waterproof, electrostatic shielding, static energy dissipative.
Type III. Type III barrier material shall be transparent, clear or colored in any colour. The appearance will be the same throughout the material. Edge throwing of component materials or finished product is not permitted except in the direction perpendicular to the rolling direction.
Type III - Transparent, waterproof, electrostatic shielding, electrostatic shielding.
When a butt weld is made on the finished product or any solid, the areas shall be marked externally with colored markers to prevent use of that part of the roll.
