If they are vacuumed and they approach 6months or 1 year mark, what would you do?

Probably preform some sort of solderability evaluation on the PCBs.

Thank you Stephen... I also mistaken it with Immersion Silver.

kumarb would you just check PCBs for solderability or would you do something in addition?

| | | 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

Component distributors now have access to a simple technical packaging which can actually eliminate shelf-life and corrosion without the use of chemicals. Why it's remained such a secret till now is beyond me, but its something I'd like help to sprea

Are there specifications or recommendations for electro-deposited tin-lead plating thickness on austenitic stainless steel that would provide a shelf life of 1 year? 6 months? Would 2 to 3 microns (78 to 118 micro-inches) 90/10 tin-lead over 1.27 mi

Hi you there, Do you have any experience upon the shelf life of PCBA which passed 100 cycles of liquid to liquid thermal stress test, 125 to -35 centigrade for 15 minutes and 5 seconds of transfer time from 125 to -35 centigarde. Will apprecia

hi' i need advise on immersion silver PCb shelf life. 1) what is the shelf life for Immersion silver PCB? 2) iF PCB expire, can we bake the immersion PCB? what temp & duration? 3) How long can we keep the pCB again after rebaking? (with vacuum seal)

Good morning James, It depends on MSD class. Refer to J-STD-033. When you open dry bag shelf life starts. You have to mount all devices before maximum allowable shelf life time exceeds. Storing in dry cabinet capable maintaining RH
