While original component manufacturers (OCMs) continue to use date codes as an indicator of when a component may be too old to perform to its original specification, this is no longer accepted as an accurate indicator of quality and reliability. Virtually all components can be used well beyond this manufacturer established date code. Original Component Manufacturers (OCMs) and traditional authorized distributors tend to store components for a few years before turning over the inventory. However, 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. One key measure of quality and reliability is solderability.

To determine the quality of aged semiconductor components in real-world applications, Rochester Electronics has performed an analysis on solderability by using an industry-standard board mount with solder paste and reflow manufacturing process. Rochester used the services of an independent 3rd party electronic manufacturing company, experienced in PCB assembly, to undertake the assembly and testing process.

These independent tests confirmed that no negative effects due to component aging were found to impact the solderability of components which have been properly stored for extended periods of time.
