Rashmi,



IPC documents talk to solderability of piece parts and printed boards, but leave the user and supplier to agree upon expected shelf life requirements (and test conditions). Sounds like you want something to apply to assemblies which will have further soldering performed at a later point. This will likely depend on condition of the boards and surface to be soldered, surface finish, packaging, storage conditions, etc. and you might be able to glean some information from J-STD-002 and J-STD-003.

Hello,



We are developing our handling documents, for that I need some information.



We get the PCBs assembled from the EMS supplier, but we are not having any guidelines on shelf life of the same.

Can you help me with the guideline for shelf life of Printed circuit board assemblies. (we are not using any battery /super cap in our assembly)

Is there any IPS standard stating the same?



Thanks for your support in advance.
