Hello, In general, what is the standard shelf life for the normal PTH and SMD components like DIP IC's, SOIC's, PLCC's? Assuming that they are non-MSD critical, what would be the proper storage method to ensure good solderability is being preserved (such as nitrogen storage chamber)? How significant is the impact of storage conditions (e.g. humidity, expose to ambient) and shelf life have on the solderability of component leads?
