Moisture sensitivity level (MSL) relates to the packaging and handling precautions for some semiconductors and 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.

Jul 23, 2019 · The Moisture Sensitivity Level – known in the electronics industry as simply “MSL” – helps identify how long a component can be exposed to 60-85% relative humidity at temperatures less than 86 degrees F before it becomes …

The Moisture Sensitivity Level (MSL) rating indicates the sensitivity of electronic components to moisture during the solder reflow process. It typically ranges from MSL 1 to MSL 6 and is specified by the component manufacturer in the datasheet.

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.

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.

Moisture Sensitivity Level (MSL) is a standardized scale used to assess the moisture sensitivity of electronic components, particularly surface-mount devices (SMDs). Ranging from MSL 1 to MSL 6, each level indicates the degree of susceptibility …

Moisture Sensitivity Level (MSL) is a classification outlined in the industry standard procedure IPC/JEDEC J-STD-020 to address the moisture absorption problem of non-hermetic packages. MSL defines moisture absorption into 6 different levels through standard test methods and criteria.

Below is a basic chart which defines moisture exposures applicable to Surface Mount Device (SMD) packages. Understand Handling and Packaging. IPC J-STD-033, like all moisture …
