I'm not sure what kind of marginal joint you're trying to identify, but when we went through a serious ball-in-cup problem a few years ago we tried hot & cold functional test as well as a day or two of -40/+125C thermal cycling and all were pretty po

Thank you to Dave and Scott!! What I'm delaing with is mass production test for small memory cards in volume! The reason I choose Non-operating temperature cycling is so that I can deal with volume. I can throw in quite a few memory cards in chambe
