How Does Long-Term Storage Affect the Mechanical Integrity and Electrical Performance of Semiconductors?
Ensuring a continuity of supply
In today’s consumer-driven society, many semiconductor Original Component Manufacturers (OCMs) are moving to shorter product lifecycles. However, multiple industries require equipment to be operational for decades, which makes continuity of supply a significant challenge.
Storing semiconductor components for extended periods after final production is one widely practiced solution. Rochester Electronics has been successfully storing components for extended periods of time to bridge supply chain disruptions for long-life applications since 1981.
When long-term component storage is a requirement, it is important for customers to have confidence that properly stored components are reliable in the field. Component mechanical integrity and electrical performance are key performance factors.
To determine the performance of aged semiconductor components, Rochester tested a random sample of components, spanning a variety of package styles that had been stored for periods up to 17 years. Components were inspected and analyzed to determine the effects of aging. Extensive testing was conducted based on optical, X-ray, and SEM imaging, decapsulation, cross-sectional inspection, and electrical testing.
The results indicated no negative results or failures due to component aging were found to impact mechanical and electrical performance for components that have been properly stored for extended periods of time.
