IPC/JEDEC Test Method J-STD-020 (see the latest revision) provides a means of testing
and classifying devices for a certain level of moisture sensitivity. The eight moisture
sensitivity levels, according to this IPC/JEDEC standard, are described in Table 1, along
with the associated floor life and soak requirements. Micron characterizes its devices to
J-STD-020 levels; results are available upon request.
