Long Term Storage
Guaranteeing the future availability of long-term storage of components is the cornerstone of successful semiconductor obsolescence management.
Semiconductor ICs are vulnerable to deterioration if not stored and monitored correctly, especially if you factor in aerospace and defence product life cycles. Ensuring these products remain suitable for application when called into use is a challenge faced by many of our clients. You can read more about our long term storage facilities in our special FAQ section on the subject by clicking here…
As a value-added ongoing solutions-support service, we offer long-term storage as a stand-alone way for you to store LTBs (Last time buys) or to ensure peace of mind for current stock. This leaves you safe in the knowledge that your application critical components are secure and guaranteed for application, regardless of the storage time frame.
We offer:
- J-STD-033 D/JEP 160 Compliant Storage
- Periodic test review for known good die (KGD) and ICs.
- Flexible storage plans for guaranteed availability when required
- Wafer probing at minimum and maximum working temperature prior to storage
- Nitrogen, Active/In-Active Desiccated Environmental options
- Long term storage options up to 10 years or more
Long- Term Storage and Assembly Frequently Asked Questions
Can long-term storage support obsolescence mitigation strategies like last-time buys?
Yes, secure long-term storage is a critical enabler of successful last-time buy (LTB) strategies. When a component is going end-of-life, buyers can purchase and store enough stock to cover their system’s lifecycle needs. Our long-term storage service ensures these parts are preserved in a stable, monitored environment, eliminating risks associated with shelf degradation or uncontrolled warehousing. This approach allows organisations to avoid costly redesigns or qualification delays in the future.
How do you ensure components remain application-ready after years in storage?
Force Technologies maintains readiness through periodic test reviews, known good die (KGD) validation, and wafer-level probing at operational temperature extremes prior to storage. By simulating application conditions and validating functionality ahead of time, we ensure that stored parts can be confidently deployed even after 10+ years. This includes maintaining full traceability and certifying that packaging, performance, and reliability standards are upheld throughout the storage period.
What are the risks of storing components without proper environmental controls?
Improper storage, especially in uncontrolled environments, can lead to oxidation, moisture ingress, lead corrosion, and degradation of packaging materials. This is particularly critical for semiconductors with fine-pitch leads or exposed die. Over time, these factors can compromise solderability, reliability, and even result in outright component failure. Controlled, standards-compliant storage (like J-STD-033D and JEP160) is essential for preserving component integrity over the long term.
