Moisture sensitivity level (MSL) is a rating established by JEDEC for electronic components that indicates the floor life of the component and provides the maximum allowable exposure for electronic components in humid environments. I’ve considered all 8 MSL classifications and explained them in detail in this article.

The Moisture Sensitivity Level (MSL) indicates the floor life of the component, its storage conditions, and handling precautions after the original container has been opened.

Moisture sensitivity level (MSL) is a rating that shows a device's susceptibility to damage due to absorbed moisture when subjected to reflow soldering as defined in J-STD-020. It relates to the packaging and handling precautions for some semiconductors.

IPC/JEDEC Moisture Sensitivity Levels (MSL) Different package types exhibit different sensitivity levels to moisture ingress and its effects. The older, through-hole, bulkier packages absorb moisture per volume at a slower rate than the thinner, surface-mount packages of recent times.

MSL 1 is the highest rating where it is considered as being not moisture sensitive even at 85% RH and components rated MSL1 do not require dry packing. The MSL rating is given after product qualification and determined by the materials used in its IC

Dec 18, 2023 · SMD components can be sensitive to moisture. Learn about the MSL levels and recommendations of the IPC/JEDEC J-STD-033 standard. SMT reflow soldering is a process in which SMD component packages are heated to temperatures above 200°C.

Moisture Sensitivity Level (MSL) is a standard defined by IPC/JEDEC J-STD-020 that indicates how susceptible a moisture/reflow-sensitive electronic component is to moisture-induced stress during storage, handling, and the PCB assembly process.

Mar 18, 2024 · Moisture Sensitive Levels are critical indicators that guide the handling and processing of electronic components in the manufacturing and assembly processes. Understanding the MSL rating of components allows for the implementation of effective moisture protection measures, ensuring the reliability and longevity of electronic devices.

Jan 20, 2025 · MSL refers to the rating of a moisture-sensitive electronic component to withstand exposure to ambient room conditions before being soldered onto a circuit board. It is a standardized rating that helps businesses determine handling, storage, and packaging requirements for these devices.

Although ROHM is continuously working to improve product reliability and quality, semicon-ductors can break down and malfunction due to various factors.
