Appreciate the check Joyce , still,
contract folks do cope (RMA) with even older ones .
"normal" = sealed ; within a year : never seen a problem .
Agree ; it is debatable , so for Shiela's sake ;
let's see what coal face guys (not spoiled OEM's) say .
Otherwise I admit my solderability test is my eye and
regular metalography ; to J 002 resign on rare occasions,
rather checking the whole process .

contract folks : soap box's yours (please)

Paul
are you sure?  Is that depending on the plating quality (edge of exposed Ni
may
come out if the plating is not very good)?  I'll use 6 month
normally...(unless did the qualification of the parts with porosity
test)...Are you assuming the parts pass the IPC solderability testing?
