WHERE MOISTURE DAMAGE ACTUALLY SHOWS UP
Moisture-sensitive components absorb humidity from the air around them, even inside a warehouse. There is no visible sign that this has happened.
The component is not damaged by moisture alone. It is damaged when heat is applied during reflow, and the moisture inside turns to steam.
The failure appears during assembly or after, once the component has already left production floor.

Common Questions
Q: How long can components remain outside of moisture barrier bags?
A: Based on IPC/JEDEC J-STD-033, the allowable floor life of components after removal from a Moisture Barrier Bag (MBB) depends on their Moisture Sensitivity Level (MSL), ranging from unlimited (Level 1) to as little as 4 hours (Level 5a) in standard factory conditions (≤30°C/60% RH). Once exceeded, baking is required before reflow.
Q: What is the recommended shelf life for desiccants used in vacuum packing?
A: Active clay or silica gel desiccants remain fully effective for up to 12 months when stored in original, unopened airtight containers. Once packed inside a heat-sealed Moisture Barrier Bag (MBB), they protect the dry environment for a minimum shelf life of 12 to 24 months, provided the bag's integrity is not compromised.
