12 Year Old Components? | 13 September, 2002

A distributor has some smt components (QFP) packaged in a vacuum sealed package with a 1991 date code. Should I accept these parts? What are the main issues I need to be concerned about? Solerability, moisture? Won't the vaccum seal package minimize those problems. Thanks

For starters, can you verify that the seal integrity is still intact?

Moisture will still seep in over 12 years. Moisture barier bags are not 100%. If you accept them, conditionally accept them, and don't pay for them untill you are happy with them.

If the leads are solderable, there is no reason not to think about accepting these parts.
