Electronic dry cabinets: Application

MSL components are sensitive to humidity and have certain requirements for the storage environment. Unlike civilian moisture-proof drying cabinets, electronic drying cabinets must reach low humidity points and have fast dehumidifying and recovery time, and they should also be ESD-safe.

During the reflow soldering process, trace amounts of water vapor penetrate the IC package, and the absorbed moisture rapidly expands inside, causing invisible damage, such as wiring failures, popcorning, micro-cracks, and even surface cracks. These defects are not easy to detect, these invisible, latent problems entered the market, bringing returns and complaints.

Normal storage	Reflow process

Moisture in the ambient penetrates into the packages.	During heating, the water steam pressure increases, that separates the die and resin.	The water steam continues to expand under heating, blowing up the packages.	The water steam breaks the packages, which causes micro-cracking.

IPC/JEDEC J-STD-033 standard specifies “Standard for Handling, Packing, Shipping and Use of Moisture/Reflow Sensitive Surface Mount Devices.”, it requires low humidity storage for moisture sensitive components.

Climatest Symor® electronic drying cabinet, also known as a dry storage cabinet, adopts an automatic dehumidifying system to protect humidity-sensitive items. The cabinet maintains a low humidity internal environment of <5%RH, which can effectively eliminate the failure caused by improper storage during assembly.

<5%RH Series dehumidifying speed:

Under ambient 25 degrees C, humidity 60%RH, open door 30 seconds and then close, the humidity will recover to <5%RH within 30 minutes, see the chart below:

WHAT ARE THE COMMON SOLUTIONS TO STORE ELECTRONIC COMPONENTS?

● Moisture barrier bags
❊ Method: The moisture-sensitive components are packed in moisture barrier bags, with desiccants and humidity indicator card (HIC) inside, users identify the humidity by checking the color change of the dots on the HIC.
❊ Disadvantage: Moisture barrier bags + HIC + desiccants + manual work = consumables, leakage risk, high cost.

● Nitrogen cabinets
❊ Method: The moisture-sensitive components are stored in nitrogen purge cabinets or compressed air.
❊ Disadvantage: Nitrogen filling = continuous N2 consumption, high cost.

● Electronic dry cabinets
❊ Method: The moisture-sensitive components are placed in an electronic dry cabinet, it automatically works.
❊ Advantages: No consumables, no manual work, no nitrogen consumption, environmental, only a little bit of electricity needed.

FREQUENTLY ASKED QUESTIONS

Q: Are the shelves adjustable or removable?

A: Yes, they are adjustable and removable.

Q: What is the maximum weight the shelf can bear?

A: Pls refer to the max. load bearing for each model, if the storage items exceed the max. load bearing, we can customize it for you.

Q: Does it require continuous power to maintain humidity levels?

A: Yes, once power is off, the humidity will rise by 10-15%RH within 24 hours, depending on your ambient humidity.

Q: What materials are applied in the construction of the cabinet?

A: The standard models use galvanized steel and tempered glass, and stainless steel dry cabinets use SS304.

Q: What is the expected lifespan of the cabinet?

A: +15 years.
