What Sets the 1490LTS Apart
Smart Nitrogen Purge Control: Integrated with our NC-5R nitrogen controller and an O₂ sensor module, the 1490LTS monitors internal oxygen levels and automatically purges nitrogen when concentrations exceed the set threshold—ensuring consistent low-oxygen storage conditions.
Dual-Mode Functionality: Easily switch between oxygen concentration or relative humidity (RH%) as the purge triggers, based on your specific storage requirements.
Fail-Safe Protection: Unlike the standard 1490V or NC-3T systems, the 1490LTS continues nitrogen purging during a power failure, offering uninterrupted protection for sensitive materials.
Purpose-Built for Long-Term Reliability: Designed specifically for storing moisture-sensitive devices (MSDs) and oxygen-sensitive components, the 1490LTS is the ideal choice for manufacturers with high-reliability storage demands.
NC-5R Nitrogen Controller with Optional O₂ Sensor Module
Our solution introduces the NC-5R Nitrogen Controller, engineered for precise atmosphere control inside storage cabinets or enclosures. Equipped with an oxygen sensor module, this system offers smart automation for nitrogen purging based on real-time internal conditions.
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.
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.
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 1490H offers the same storage capacity as the 1490V with a safe, effective low-temperature bake function added to renew exposed components.
The best performance of the dry cabinet is achieved under the ambient condition of temperature below 30°C and relative humidity below 60% RH.
Use Manncorp Ultra-Dry Storage Cabinets to Protect and Store:
- ICs and components in reels, trays, sticks, feeders or loose in bins or bags prior to placement.
- Multilayer PCBs and bare boards meant for military and other class 3, high-reliability products.
- Double-sided boards that have been partially assembled.
- Moisture-absorbing materials, such as epoxy, resins, chemicals and adhesives.
- Films and plastics used in production.
