What is MSL standard?

The MSL is an electronic standard for the time period in which a moisture sensitive device can be exposed to ambient room conditions (30 °C/85%RH at Level 1; 30 °C/60%RH at all other levels). Increasingly, semiconductors have been manufactured in smaller sizes.

What are MSL ratings?

The MSL rating is given after product qualification and determined by the materials used in its IC packaging and assembly process is based on a constant 30°C and constant relative humidity. In practice, the absorption of moisture into an IC package is proportional to temperature and relative humidity.

How do I know my MSL level?

MSL testing is usually performed at two levels to determine the level of capability at the highest and lowest temperatures that the SMD is expected to see during its actual assembly. IPC/JEDEC J-STD-020 is the standard approach in determining a package’s moisture sensitivity level.

What is MSL in manufacturing?

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.

How do you store moisture sensitive components?

Moisture sensitive components must be placed in a Moisture Barrier Bag (MBB) with a fresh desiccant and RH indicator. The moisture barrier bag is then sealed and a caution or bar code label is placed on the MBB.

What is Super Dry desiccant used for?

SUPER DRY desiccants are made from highly hygroscopic Calcium Chloride and starch engineered to absorb moisture from the air, thus reducing the humidity in a controlled environment like poly bags, carton boxes, and containers.

What is moisture barrier bag?

Moisture barrier bags, (sometimes called foil bags, alufoil bags or Mylar bags), are one of the most effective packaging solutions on the market today to protect against corrosive damage caused by humidity, moisture, oxygen, salt spray, aromas, grease and other airborne contaminants.

How long is desiccant good for?

We recommend that a desiccant be replaced once every three years for open-cycle systems and once every two years for closed-cycle systems. A desiccant may degrade more quickly depending on the environment where it is used. Dew point temperatures offer a good indication for when to replace your desiccant.
