Humidity is one of the most underestimated risks in electronics manufacturing and storage environments. Moisture absorption in electronic components can lead to oxidation, corrosion, micro-cracks, and catastrophic failures during reflow soldering processes.
When moisture-sensitive components absorb ambient humidity, trapped water vapor expands rapidly under high temperatures. This expansion can cause internal delamination — commonly known as the “popcorn effect” in PCB assemblies.
Common Moisture-Related Failures in Electronics
For manufacturers operating SMT lines, maintaining low humidity storage is not optional — it is essential for yield protection and long-term reliability.
What Is a Dry Cabinet?
A dry cabinet is a low humidity storage system designed to maintain controlled relative humidity (RH) levels to protect moisture-sensitive components.
Modern ultra low humidity dry cabinets can maintain environments as low as 1% RH, providing reliable protection for:
Unlike temporary solutions such as silica gel, dry cabinets provide continuous and automated humidity control.
The IPC/JEDEC J-STD-033 standard defines storage, handling, and floor life requirements for moisture sensitive devices. Key requirements include: Controlled storage after bag opening Floor life…
