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 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.

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 J-STD-033 is the electronics industry standard for handling, packing, shipping and use of Moisture, Reflow and Process sensitive devices. This standard includes a factory floor life table at 30°C dependant on the component MSL rating, as shown in Table 1. Table 1. Factory Floor Life @ 30°C.

Apr 26, 2016 · Peak Body Reflow Temperature determined per JEDEC J-STD-020. Requires dry pack. & May observe delamination; classified MSL 1 per J-STD-020 Annex A Reliability Assessment. Hermetic package, not moisture sensitive.

Mar 18, 2024 · Moisture Sensitive Levels (MSL) play a crucial role in the handling and reliability of electronic components, especially those that are sensitive to moisture-induced damage. The MSL designation provides valuable information about the susceptibility of a component to moisture absorption and outlines guidelines for proper storage and handling.

Dec 18, 2023 · 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. If such an package contains a significant amount of moisture, heating it can cause a rapid release of moisture vapor.

Vulnerability to delamination especially during Pb-free reflow soldering will be one of the main driving forces in determining BMP module MSL ratings. This paper will present results of moisture studies performed on Lineage Power PCBs and Modules.

plastic packages can induce cracking. Such cracking is caused by extreme internal pressure created by moisture va-porizing under the hot temperature of solder reflow condi-tions. Once cracked, the surface mount package reliability is compromised, leading to potential corrosion of the device by moisture and ionic contaminants.

The MSL rating system helps electronics manufacturers determine proper handling, packing, and use of moisture-sensitive devices (MSDs) to avoid damage caused by absorbed moisture during reflow soldering.
