Understanding the Hidden Risks of Long-Term Storage
For industries with long product lifecycles, such as aerospace, defense, industrial automation, and medical devices, understanding these aging mechanisms is critical.
Diffusion: The Invisible Degradation Mechanism
- Atoms migrate between materials (e.g., copper and tin).
- Leads to intermetallic phase growth.
- Degrades solderability and mechanical integrity.
In conventional storage, this process continues steadily, making it one of the main causes of long-term failure.
Why it matters: Even if a component looks intact, its internal structure may already be compromised.
Oxidation and Corrosion
- Residual oxygen and moisture remain present.
- Oxidation layers form on metal surfaces.
- Corrosion reduces electrical performance and reliability.
Traditional storage methods only slow down these processes—they do not eliminate them.
Looking to secure your components for decades?
Outgassing: The Internal Threat
- Plastics
- Adhesives
- Coatings
- Additives
- Corrosive compounds
- Organic vapors
- Residual solvents
This is one of the most underestimated risks in electronics storage.
Moisture and Environmental Contaminants
- Promote electrochemical corrosion
- Trigger chemical reactions
- Damage encapsulations and interfaces
Contaminants such as sulfur compounds or chlorine gases can further accelerate degradation.
Critical Failure Mechanisms: Whiskers & Tin Pest
- Tin whiskers: microscopic conductive filaments causing short circuits
- Tin pest: structural transformation weakening materials
These phenomena can develop silently during storage if not properly controlled
Material Interactions in Complex Systems
- Multiple materials interact unpredictably
- Adhesives release gases affecting nearby components
Optical and electrical properties degrade.
Displays, for example, may suffer changes in optical properties, such as:
- Loss of brightness
- Color shifts
- Pixel failures
Functional Degradation in Assemblies
- Capacitor degradation (leakage current, capacitance loss)
- Residual process contaminants are causing corrosion
- System-level failure due to component interaction
In worst cases, this leads to total device failure during operation.
Why This Matters for Your Business
Conclusion:
Aging Is Multi-Factorial - Storage Must Be Too
- Diffusion
- Oxidation
- Contamination
- Material interactions
> A single-parameter solution is not enough.
To ensure long-term availability and reliability, storage strategies must address all degradation mechanisms simultaneously.
