概要
Moisture Sensitivity Level tells you how a surface-mount component must be stored and handled before reflow, and getting it wrong leads to popcorning, delamination, and rework. Part Risk Manager surfaces the JEDEC J-STD-020 MSL rating, floor life, and bake-out requirements in one place, so procurement and manufacturing work from the same data. You pull MSL alongside the rest of a part's risk profile in a single record, keeping handling decisions traceable from sourcing through the floor.
Moisture sensitivity data is usually buried inside datasheets and packaging documents, and it changes as manufacturers update packaging or processes. Searching each PDF by hand is slow, and a number copied incorrectly can put a part on the line with the wrong storage assumption. Part Risk Manager normalizes the MSL rating per IPC/JEDEC J-STD-020 and presents it in the part record, so procurement and manufacturing see the same sourced rating instead of reconciling separate datasheet copies.
An MSL rating only helps if the floor knows what it requires. Each part shows its floor life and storage conditions next to the MSL level, so the team knows how long a component can sit out of a dry pack and when bake-out is needed before reflow. That connects the rating to the action it drives: dry storage, exposure tracking, and bake schedules. The result is fewer assumptions at the bench and fewer solder defects from mishandled devices.
On a full BOM, moisture-sensitive parts need special storage and handling, and they are easy to miss among hundreds of line items. Part Risk Manager lets you filter a BOM by MSL so every component requiring controlled handling is visible at once. That gives manufacturing a clear pick list for dry storage and exposure tracking, and gives sourcing an early read on which parts add handling cost and process steps.
MSL is one signal among many in a part's risk picture. In Part Risk Manager it sits alongside lifecycle status, compliance, PCN history, and sourcing data, so you evaluate handling requirements in the same view as obsolescence and supply risk. When a PCN changes a part's MSL rating, Part Risk Manager flags it for components already active in your BOM, so a packaging change does not quietly invalidate your storage plan. Moisture sensitivity becomes a tracked attribute, not a one-time lookup.

よくあるご質問
MSL is a classification under IPC/JEDEC J-STD-020 that defines how long a surface-mount component can sit in ambient conditions before it must be reflowed or baked. Levels run from 1 (unlimited floor life) to 6 (mandatory bake before each use), because absorbed moisture can vaporize during reflow and cause popcorning. Part Risk Manager shows the MSL level so handling rules are clear before assembly.
MSL ratings come from manufacturer packaging and datasheet documentation, normalized into the part record so you do not have to open each PDF. The rating is shown with floor life and storage conditions, and because it lives in the part profile, it stays connected to lifecycle, compliance, and PCN tracking.
Manufacturers sometimes change packaging or process in a way that updates a component's MSL rating, published through a PCN. Part Risk Manager flags MSL changes for parts already active in your BOM, so your storage and reflow plan reflects the current rating instead of outdated handling instructions on the floor.
