Electronic dry cabinet, also called humidity cabinet, moisture proof cabinet, desiccant dry cabinet or dry box, is used for storage of surface mount electronic components prior to circuit board assembly, to prevent water absorption that could flash into steam during soldering, which destroy the components.
Tuesday, April 23, 2013: Moisture related problems in electronic assemblies and components cause post-reflow ‘popcorning’, laminate melting and other defects. Dry cabinets have proved to be an effective solution to these issues. They not only protect but some models can also restore impaired moisture sensitive devices (MSDs) with a combination of ultra low humidity and mild heating temperatures. These factors also prevent damage to the heat susceptible component enclosures—tapes, trays and reels—as well as plastics and films used in assemblies. The desiccant inside the cabinets absorbs trapped moisture inside and is self-replenishing.
Electronic dry boxes contain a small peltier cooler, which removes moisture from the air by condensing it out. A control dial is usually provided that permits the user rough adjustment of the humidity level. More sophisticated designs link the cooler to a settable digital hygrometer, allowing very precise humidity level control.

Model: SL-306CA, Brand: EDRY, Manufacturer: EDRY Co Ltd, Taiwan
SL-306 CA is a superior cabinet in terms of dehumidification power, speed of dehumidification after door opening, life span and energy saving.
Key Features
- Extreme speed desiccating performance: Ultra low humidity main desiccating unit to lower the humidity level to less than 10 per cent within 5 minutes and maintain stable 1% RH lowest humidity level in long period of time. One hour after power up, even with power interruption, it will maintain less than 15%RH humidity level in a period of 24 hours. It can completely replace nitrogen filling and other dry air equipment.
- Speedy humidity reduction even with multiple door opening: Can maintain a maximum of 70 hours of desiccating capability. Multiple door openings will allow humidity level speedy reduction, fully in compliance with the requirement of instant access to storage items.
- Patented speedy desiccation: Uses patented speedy desiccating design to allow desiccating process more stable and the humidity level will not fluctuate. Other brand products uses shape memory alloys, not only slow in starting desiccating, but the humidity level returns to more than 10 per cent during desiccating process
- World leading patented technology: Won three key patents. All it takes is one main desiccating unit which will bring humidity level down to 1 per cent easily. It not only reduces energy consumption, but also future maintenance cost.
