     Address,
     
     I would like to know the same.  I have had some components that would 
     not solder properly, leaving opens.  Granted some of the problems were 
     related to the PCB, but how can I identify retention periods for 
     components?  Can the same retention periods be applied to components 
     as PCBs (proper storage, dessicants, cleaning, etc.)  Please advise.

Dear Technetters,
     
I have a simple question.
     
What is the standard " Shelf life "  for the normal PTH and SMD 
components like DIP IC's, SOIC's, PLCC's etc. ?
I would like to know the time from Date of Mfg. to the time the 
component is assembled ( either reflow or wave solder ).
     
Thanks in advance.
GKBhat.
