3600 Drying Storage Cabinet
Why Do You Need Dry Storage?
• RoHS Requires Higher Temperatures For Reflow Soldering
• Components Complying with RoHS must be more Resistant to Temperature than Conventional Components.
• Higher Process Temperatures Increase the Requirements on the Storage of Moisture-Sensitive Components.
• The Plastic Packages of ICs particularly Absorb Water. This Water Evaporates during Soldering and Applies Pressure to the Packages.
• Stress caused by Water Vapor (1700 times the Volume of Water) inside the Package Leads to Delamination and/or Cracks (Popcorn Effect).

Delamination = • Delamination is a Form of Failure of Laminated
Composite Materials. Repeated Cyclic Stress, Impact etc. can cause Layers to Separate, Forming a Mica-Like Structure of Separate Layers, with Significant Loss of Mechanical Toughness. Delamination is an Insidious kind of Failure as it Develops inside the Material, without being Obvious on the Surface, much like Metal Fatigue.
Delamination Problems may be Detected in the Material by its Sound: Solid Composite has Sharper Sound, while Delaminated Parts sound Dull. Other Non-Destructive Testing Methods Involve Embedding Optical Fibers coupled with Optical Time Domain Reflectometer Testing of their State, Testing with Ultrasound, Infrared Imaging, etc.

Innovative Drying Storage Cabinet
• RM Michaelides Realized that a Drying Storage Cabinetmust Provide Different Humidity Levels.Therefore, RM Developed a Drying Storage Cabinet withThree Separate, Independently Controlled Chambers.
• Different Humidity Levels can be Set for each Chamber.
• Low Consumption and Costs
• Operating Data Provided via CAN, RS232, Bluetooth,USB, WLAN or GSM
• Integration into Process Traceability is Possible
