SMT modules using SkyTraq’s devices listed in section 1 are moisture sensitive and should be handled within proper MSL 3 guidelines to avoid damage from moisture absorption and exposure to solder reflow temperatures that can result in yield and reliability degradation.

Most semiconductor products are rated MSL3 or higher. 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.

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.

2019年7月23日 · The electronic industry has addressed this issue in JEDEC standard J-STD-033B by setting standards for handling, packaging, shipping and use of parts with moisture sensitivities. MSL-affected parts are packaged in moisture barrier bags and shipped with humidity indicators and appropriate MSL labels.

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.

MSL 3: Components at this level are moderately sensitive to moisture and have a limited floor life. Exposure to ambient air should be minimized, and they typically require more stringent handling and storage procedures.

2018年7月18日 · It's a less serious problem for high volume components, but it's a huge issue for small lot, high value components. Therefore, it's important to take proper care in handling these. That's the topic we'll explore today. 1. Storage requirements. The first step in proper handling is proper storage when not being actively used.

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 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.

2024年3月18日 · Components classified as MSL 2 or MSL 3 have moderate sensitivity to moisture. They may require additional precautions during storage and handling to prevent moisture absorption. Components with MSL 4 or MSL …
