I know the approximate shelf life for good and OK storage of ENIG and Ag boards but I do not know what these times are like for HASL. Can anyone help me out here. Thanks.

Tyco had a good read on the shelf life of tin plating and the different variables involved in determining it's shelf life. http://www.tycoelectronics.com/documentation/whitepapers/pdf/Keeping_Tin_Solderable.pdf

Ideally, shelf life should be twelve months from application, but not all OSP's are the same so check manufacturer's instructions

In my case most of the PCBs are OSP finishing and worst case of MSD component on bottom side is level 3 (168 hours). You mean that PCB shelf life with bottom side assembled shoud be 84 hours?

Does isopropyl alcohol have a shelf life? I have looked at many manufactures and have not found any publication of a TDS specifying shelf life, rather only a MSDS which does not include this info.

| I have been asked to supply a maximum shelf life for our assemblied PCB's. I realise this is dependent on so many factors- temperature, humidity, no of layers etc. But does anyone have a formulae for calculating shelf life, or does anyone know of a

Tough to say. TI used Pd. Ask your supplier.

Thank you for your feedback, I've also looked at the archives on this issue & found useful information there as well.
