What humidity level is safe for electronic components?

There is no single safe humidity level for every electronic component. For moisture sensitive devices, PCBs, SMD reels, and trays, controlled low-humidity storage is recommended. Follow IPC standards for moisture control explained (J-STD-033) when establishing storage procedures.

Why It Matters

Ordinary room humidity can allow sensitive electronics to absorb moisture over time, increasing the risk of package stress, oxidation, corrosion, solderability problems, and reliability issues.

Best Practice

Store moisture-sensitive electronics in a dry cabinet, dry box, or humidity controlled storage cabinet. For sensitive components, maintaining less than 5% RH, ideally around 1–2% RH, provides ultra-low humidity storage. View Dry Cabinet Systems.

Why XDry
XDry dry cabinets are self-contained, nitrogen unnecessary, and provide ultra-low RH storage for MSDs, PCBs, reels, and trays while helping manufacturers determine what RH level should you set your dry cabinet at for safe long-term electronics storage.

FAQ
Q: Why use a dry cabinet?
A: To prevent moisture-related damage by storing them in a low-humidity environment (less than 5%). Doing so keeps printed circuit boards and electronic components ready for production and eliminates harsh preproduction baking cycles.

Q: What RH is ideal?
A: Ultra-low humidity for sensitive electronics needing to be stored in an environment of less than 5%, ideally closer to 1-2%
