Baking is needed to reset the floor life of MSDs, to deal with MSDs that the exposure time has exceeded the floor life in the ambient environment or even the MSDs that expose in the environment for only a short time. Backing can extend the storage time and ensure the quality safety. However, with the development of new style of chip encapsulation and mounting technics, the traditional high temperature backing shows its shortcomings.

 

Problems Caused by Traditional High Temperature Baking

Some MSD reels and racks are not suitable for high temperature baking, and the efficiency would be very low if baking after taking off the MSDs from the racks.

Some MSD components and PCBs can not bear high temperature baking for a long time.

For some other MSD components, if the temperature is higher, the damage caused to the

components would be more serious, even though the components can bear the high

temperature, there would still be potential thermal destruction and oxidation, or there would

be inter metallic growth at the inner joint of the components, reducing solder ability.

Baking is only possible one time according to IPC, and the components must be processed

at once after baking to avoid re-absorption of moisture.

 

With the popularity of IPC/JEDEC J-STD-033C, people are taking more consideration on the the double functions of dry cabinets with ultra-low humidity and medium temperature baking. Our Super Dry medium temperature baking cabinets MSD Series install a 50 (Set from room temperature to 50 ) heater into our dry cabinets to acceralate the dehumidification. And if the MSD Series are used in all production processes, not only the defective products caused by thermal stress can be avoided, but also the process can be simplified and the production cost be reduced.

 

Features of MSD Series

 

Advanced ultra-low humidity technology, effective thermal insulation to make the

energy consumption the lowest.

Steady environment of 50 +2%RH.

Effective dehumidificatin to make sure a short recovery time after door open and close.

Digital control panel for easy operation.

ESD safe design.

 

Why Choose MSD Series?

 

No need of pre-baking: To prevent the defective products.

Mild baking: Cause no flaws to SMDs during dehumidification.

Moisture prevention: To prevent moisture absorption in one hour after taken from the cabinet.

 

Super Dry MSD series is added the function of medium temperature baking. The heaterand dry unit work together to speed the drying , the humidity can reach thelowest 2%RH, which can meet the requirement of  IPC/JEDEC J-STD-033C. Medium temperature baking can also avoide the oxidation caused in the traditional hightemperature baking.
