Dry Cabinets for Optoelectronics Components and Materials
Controlled ultra-low-humidity storage for LEDs, OLEDs, optical sensors, laser components, capacitors, solar cell materials and sensitive assemblies.
McDry helps reduce exposure to uncontrolled ambient humidity during receiving, intermediate storage, production, inspection, research and long-term sample storage.
Helps reduce moisture exposure during storage between production processes.
Selected configurations support electrostatic-sensitive components and devices.
Supports more repeatable storage conditions before assembly, sealing or inspection.
Moisture can influence sensitive optoelectronic materials and components
OLED materials, organic electronic materials, perovskite materials and selected semiconductor or thin-film components can be sensitive to uncontrolled humidity during storage and handling.
McDry provides an enclosed low-humidity environment for suitable components and materials between receiving, assembly, bonding, coating, sealing, inspection and testing.
What uncontrolled humidity may influence
The effect depends on the material, construction, packaging, exposure time and manufacturing process.
Material degradation
Moisture may influence selected organic, semiconductor and thin-film materials.
Oxidation and corrosion
Selected electrodes, terminals and metallic components may be affected by uncontrolled humidity.
Surface and bonding issues
Moisture or contamination may influence coating, bonding, encapsulation and assembly processes.
Storage variability
Different storage conditions may introduce variation between production batches and evaluation samples.
Components and materials that may benefit from dry storage
Suitability and required humidity must be reviewed for the specific component, material and process.
LEDs and lighting components
LED packages, lighting devices and related moisture-sensitive electronic parts.
OLED and organic EL materials
Display modules, flexible OLED materials, organic materials and related assemblies.
Optical sensors and lasers
Photodiodes, image sensors, laser diodes, optical modules and precision assemblies.
Solar cell materials
Perovskite materials, sensitive films, substrates, electrodes and encapsulation parts.
Capacitors and electronics
Selected capacitors, IC packages, mounted PCB assemblies and sensitive parts.
R&D and QA samples
Prototype devices, reference samples, failure-analysis items and reliability-test samples.
Dry storage for OLED and perovskite materials
These materials can require careful environmental control, but their exact storage requirements are application-specific.
OLED and organic EL materials
A controlled low-humidity environment may help reduce moisture exposure for suitable OLED materials, display-related components and flexible organic electronic materials during intermediate storage.
McDry may support storage before assembly, bonding, coating, sealing or inspection, subject to the component manufacturer’s instructions and the required process environment.
Perovskite and solar cell materials
Selected perovskite materials, thin films, substrates, electrodes, encapsulation parts and research samples may benefit from controlled low-humidity storage between preparation and use.
Some materials or processes may also require inert-gas, oxygen-free, dark or otherwise controlled conditions. A dry cabinet must not automatically be assumed to replace a glovebox or dedicated process environment.
Typical materials, risks and storage considerations
| Application | Moisture-related concern | How McDry may support storage | Important review point |
|---|---|---|---|
| LEDs and OLEDs | Moisture uptake and degradation of selected materials or packages | Controlled low-humidity storage between processes | Packaging, ESD and required humidity |
| Optical sensors and lasers | Surface condition, oxidation and contamination | Enclosed storage before assembly or inspection | Cleanliness and component sensitivity |
| Solar cell materials | Sensitivity of selected films, electrodes and research materials | Storage of approved materials and samples | Some materials require inert or light-controlled conditions |
| Capacitors and electronics | Moisture uptake, oxidation and storage instability | Controlled storage before mounting or testing | MSL, packaging and manufacturer instructions |
| R&D and QA samples | Variable conditions between tests | More repeatable storage for suitable samples | Material identity and safety classification |
Use controlled storage between critical process steps
Receive
Review packaging, component information and storage requirements.
Evaluate
Confirm humidity, ESD, cleanliness and safety conditions.
Store
Place approved items in the selected McDry configuration.
Process
Remove items for assembly, bonding, sealing, inspection or testing.
Return
Return unused approved items promptly to controlled storage.
Controlled ultra-low-humidity storage without continuous nitrogen consumption
McDry uses a zeolite-based drying unit to maintain a controlled dry environment. Depending on the selected model and operating conditions, storage down to 1% RH is available.
Selected models provide controlled storage down to 1% RH.
Suitable options support electrostatic-sensitive devices and components.
Standard operation uses an automatically regenerating zeolite drying unit.

Confirm the complete storage environment before use
McDry is not automatically a replacement for a cleanroom, glovebox, inert-gas system, vacuum packaging or a temperature-, oxygen-, particle- or light-controlled process.
Wet, volatile, flammable, explosive, reactive or otherwise hazardous substances must not be stored without prior technical and safety review. Provide an SDS where applicable.
