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?
