Ultra-Dry 1490H Baking Dry Cabinet

Extra-large baking dry box restores shelf life of moisture-sensitive devices

Manncorp’s Ultra-Dry "H" series 40°C baking boxes can restore exposed moisture-sensitive devices (MSDs) to new condition without the solderability problems, such as oxidation and intermetallic build up, caused by conventional 125°C baking processes. Components and assemblies can also be stored indefinitely in these boxes with no harmful effects. Model 1490H is the largest of the baking cabinets, with 44.1 cu. ft. (1250L) capacity. It includes datalogging capability.

Ultra-Dry 1490H Baking Desiccant Cabinet

Restore & Store MSDs

Components and assemblies that have been exposed to ambient environments prior to reflow are at risk for moisture damage, such as popcorning, tombstoning and other serious, and often hidden, defects that can remain undetected until the product is in the field. Exposure can happen during shipping or storage, from improper closure of or tears in MSD package, or improper handling. Don’t throw out expensive exposed components and assemblies however: reset their shelf life with a low-temperature baking cabinet.

Reset the floor life of moisture-exposed components
Ultra-Dry "H" series desiccant baking cabinets restore moisture-exposed parts and assemblies to full use with a low-temperature (40˚C) bake function that gently warms the moisture out without harming sensitive components, laminates or PCBs—no matter how long they remain in the baking cabinet.

This low temperature also means there’s no need to remove components from their low-temperature carriers—tapes, trays, sticks—before baking.

Low-humidity environment for storage
The "H" cabinets can be used to store and protect components, bare boards and partial assemblies, with or without the bake function activated, in an RH atmosphere of <5. The box’s dryer-than-the-Sahara RH of <5% is significantly lower than specified by IPC/JEDEC J-STD-033C, and far more than enough to prevent moisture traces that cause microcracking, popcorning, delamination and solder joint failures.

Data logging included
The cabinet's digital display also functions as a data logger, allowing companies to keep and review temperature and humidity history on the cabinet. The 2-channel data logger measures both temperature and humidity inside the cabinet. Included Windows-based software provides tools for displaying and evaluating the collected data. Data reports can be printed, exported or emailed. The software allows the data logger to be configured for C or °F, sample rate, high/low alarms and data logging intervals. 

All "H" cabinets meet and exceed J-STD-033B standard for floor-life restoration and storage.

Nitrogen environment available
Nitrogen systems are available as an option.
