McDry Dry Cabinets for SMT & MSD Storage
Ultra-low humidity storage for SMD reels, IC packages, PCBs, and moisture-sensitive devices.
McDry supports the controlled dry storage of moisture-sensitive devices (MSDs) in SMT and semiconductor manufacturing. A consistently dry storage environment helps limit additional moisture absorption during storage and production.
McDry supports MSD and floor-life management and helps reduce the risk of moisture-related damage during reflow, including popcorning and micro-cracking.

How McDry Protects Moisture-Sensitive Components
Controlled dry storage for MSDs, SMD reels, IC packages, and PCBs in SMT and semiconductor manufacturing.
Moisture can be absorbed by MSDs and other sensitive electronic components during storage and handling. During the subsequent reflow process, absorbed moisture can increase the risk of moisture-related damage such as popcorning and micro-cracking.
McDry provides a controlled, very low-humidity environment that helps limit additional moisture absorption during storage. This supports MSD and floor-life management in SMT production.
The dry unit uses a zeolite-based adsorption system. Absorbed moisture is removed through automatic regeneration cycles using heat. For standard dry storage, no continuous nitrogen supply is required.
How do microcracks develop?
Normal storage
Water vapor
Humidity diffuses into the IC during storage.
Reflow process
Accumulation of moisture, increase in pressure
The interface between the matrix and the resin is peeled off by the water vapor pressure during the reflow process.
Reflow process
The packaging is inflated by expanding moisture
When heated further, the steam expands and stretches the packaging.
Reflow process
The IC housing has cracks.
The packaging releases the water due to the pressure, which leads to cracks.
