I'm managing several designs. At one point I identified a few failures that were caused by 0603 caps failing short. After that I switched to all soft-term caps to hopefully eliminate the problem.
Well it's been several years and the problem has not re-occurred that I know of. So I guess it did work, but keeping these soft term caps adds a lot of cost to every board.
So here's what I'm wondering. To those of you who've produced a lot of boards: is this normal? I'm making products that need to last, but they're not safety critical or anything like that where extreme care is required. They're also not used in a high-shock environment (besides being shipped).
If it's really uncommon to have to do this, I'm considering reviewing the designs for board-flex and switching back to regular caps.
