Dear Hui Luo,

I have never seen a document that established this type of requirement.  I assume the temperature and humidity requirement would be similar to the PCB.  I assume also there would be more concern about ESD control.



Best regards,
Dave

Dear David and other IPC officers,

Besides below, can you help to advise is there any documentation to
describe the shelf life/storage condition/handling requirment for the PCBA
after SMT or wave soldering?

 Can anyone advise me are there any documentations which indicates the PCB  
 raw material, bareboard or PCBA storage conditions and shelve life.        
                                                                            
 Have anyone of you experience PCBA after storage of one year have appear   
 via holes failure issues? Anyone have ever encounter or studies in this    
 area?
