Ultra-Dry 290V PCB Dry Box for MSD Storage

Protect MSDs

Prevent moisture-related damage and failures
Serious defects and failures, including many that don't show up until the product is in the field, can result from improper storage of moisture-sensitive electronic components and assemblies.

Manncorp's V series desiccant cabinets eliminate these failures, along with the risk of moisture-related defects resulting from damaged or improperly resealed moisture barrier bags (MBBs).

Eliminate ongoing consumable expenses
The humidity-controlled cabinets also eliminate the ongoing expense of humidity indicator cards (HICs) and desiccant bags.

Do more with cabinets
Unlike moisture barrier bags, dry cabinets for electronics components can be used to easily protect loaded tape and stick feeders, partially assembled PCBs, and high-layer-count or class 3 bare boards.

Low-humidity environment for storage
"V" series cabinets use a stand-alone thermo-hygrometer and regenerating desiccant to provide the best possible low-humidity environment for components and assemblies. These cabinets feature two or more turbo modules designed to rapidly reduce RH levels to ≤5% without the use of nitrogen or compressed air.

An RH of ≤5% is significantly lower than specified by IPC/JEDEC J-STD-033C—far more than enough to prevent moisture traces that cause microcracking, popcorning, delamination and solder joint failures.

Nitrogen environment available
Nitrogen systems are available as an option.

What if your components have already been exposed to moisture?
Don't throw them out! Their shelf life can be fully restored using a low-temperature baking cabinet. Ultra-Dry model 290H offers the same storage capacity as the 290V with a safe, effective low-temperature bake function added to renew exposed components. Learn more
