Does anyone have any information regarding the shelf life of leadless 
pre-tinned components(chip caps and resistors, LCC packages)?

First, what is the shelf life for these components when stored without 
significant precautions (ie. stored in orginal packaging, 20 to 50% R 
humidty and temperature 72 +/- 10 degrees).?

What is the recommended storage to enhance shelf life? ie controlled 
temperature humidity etc. and do you have data on how long the shelf life 
can be increased.

How does one go about testing shelf life for components packaged on a reel?

By testing the first components on the reel does that give a good indication 
of the parts in the end of the reel?
