Hello Juan! The "rule" you are remembering is the old MIL-STD-2000 
specification requirement that stated if you used hot solder dipped 
components, you had a 2 year shelf life before being required to 
re-confirm component solderability. The current IPC JSTD 001E, paragraph 
4.4 requires that a manufacturer ensure that components are solderable and 
that the manufacturer should establish procedures to minimize 
solderability degradation. In a nut shell, the manufacturer needs to have 
a plan/process/protocol demonstrating that they have control of their 
component solderability.

[TN] Solderability maintenance (#3.9.2)






Is there anybody out there that remembers where is the "rule" to solder 
the components before 2 years (from their D/C, I suppose)?

This question is  referred to SMD -reeled- components.

Thank you.

Juan
