While there is no direct link between protection from ESD and protection from moisture, many devices and components require protection from both.
Statshield® Moisture Barrier Bags
(MBB) are designed to protect the contents from both moisture and ESD events. MBBs protect ESD susceptible devices by forming a
faraday cage
around the contents and they protect the contents from moisture with specialized layers of film that control the Moisture Vapor Transmission Rate (MVTR). In addition to the bags,
Desiccant Packs and Humidity Indicator Cards are recommended b
e used for complete moisture protection. The moisture barrier bag can be heat sealed with a vacuum-sealer
to eliminate the amount of "moisture laden oxygen" within the package.
Most manufacturers of the Moisture Sensitive Devices (MSD) will dictate how their product should be stored, shipped, etc. However, the IPC/JEDEC J-STD-033C standard describes the standardized levels of floor life exposure for moisture/reflow-sensitive SMD packages along with the handling, packing and shipping requirements necessary to avoid moisture/reflow-related failures.
User guide CLC/TR 61340-5-2 clause
4.8.3.2.2
"
While only specialized materials and structures can control the interior temperature of a package, it is important to take possible temperature exposure into account when shipping electronic parts. It is particularly important to consider what happens to the interior of a package if the environment has high humidity. If the temperature varies across the dew point of the established interior environment of the package, condensation may occur. The interior of a package should either contain desiccant or the air should be evacuated from the package during the sealing process. The package itself should have a low WVTR."
