Hello Technetters, it's a while since I have been here..
(I only ask here because Steve woke up & popped into the DesignerNet forum 
reminding me about here :-)

I have been looking into our stocked components to improve my PCB program's 
libraries to match what we stock etc.

I am coming across several components that we appear to have many 
thousands of, yet are little used ("that" buyer no longer works for us - lol)
I.E. we have a BAV99 SOT23 diode that was purchased  in 1992, 94, 94.
(it is used on a single board - only a few a year)

These are sat on a shelf, on the reel in a black anti static bag.
No air conditioning/humidity control etc.

Pulling the first diode off the reel & using a jewellers eyeglass I can see that 
the legs look a little brown (tarnished).

I'm interested in what others do about this type of situation, do you have a 
policy on using old components?

Do tarnished legs cause big problems soldering with lead free solder?

Thank you,
Matthew Lamkin.
