Moisture sensitive devices are packaged in a moisture barrier antistatic bag with a desiccant and a moisture indicator card which is sealed. Moisture sensitivity levels are specified in technical standard IPC/JEDEC Moisture/reflow Sensitivity Classification for Nonhermetic Surface-Mount Devices. [1]
The building materials industry also manages the moisture barrier properties in architectural components to ensure the correct moisture levels in the internal spaces of buildings. Optoelectronic devices based on organic material, generally named OLEDs , need an encapsulation with low values of WVTR to guarantee the same performances over the ...
The previous United States Military Specification Mil-I-8835A [permanent dead link ] was the governing specification for a humidity indicator card. The humidity indicator card is also specified for use in J-STD-033, which is the standard for handling, packing, shipping and use of moisture/reflow sensitive surface-mount devices.
An antistatic bag is a bag used for storing electronic components, which are prone to damage caused by electrostatic discharge (ESD). These bags are usually plastic polyethylene terephthalate (PET) and have a distinctive color (silvery for metallised film , pink or black for polyethylene ).
Concurrently to the oxygen barrier property, the permeability of water vapor through a food packaging system should be minimized to effectively prevent physical and chemical changes connected to an excessive moisture content. [52] The moisture barrier properties of a material can be assessed by measuring the water vapor transmission rate (WVTR ...
In construction, a building or structure is waterproofed with the use of membranes and coatings to protect contents and structural integrity. The waterproofing of the building envelope in construction specifications is listed under 07 - Thermal and Moisture Protection within MasterFormat 2004, by the Construction Specifications Institute, and includes roofing and waterproofing materials.
