Component Shelf Life

[thamx]

I'm conducting research over the shelf life of components, the effects of ageing and the reason why different suppliers define different shelf life rules.

We, as a factory, place a lot of Intel (former Altera) components and those are delivered with a shelf life specified.
Other research concludes shelf life has, in lead-free finishes, no (big) influence on solderability and thus plays no significant role.

What I'm looking for is the rationale behind a shelf life definition: how is it defined and what are effects on the components if we exceed this shelf life?

The reason for my research is to define a clear, well-founded conclusion how we, as an EMS factory or even as an Industry, define and handle shelf life.

I'm looking forward to your response, hopefully some (research) papers are available.

Hello,

We do not have research paper and we will usually update the status of our FPGA on this website: PCNs, PDNs, and Advisories

We do have KDB about shelf life of a ball-grid array (BGA) device after removing it from its dry pack: https://www.intel.com/content/www/us/en/support/programmable/articles/000079237.html

Here's another related document: https://www.intel.com/content/dam/altera-www/global/en_US/pdfs/literature/pcn/adv1616.pdf

We follow standard JEDEC J-STD-033B.1

I hope this helps.
