Who sees post 2006 hardware with bad caps?

Me, just about every day of my working life ...


Any particulat brands ?


Nope. The two main things that they always have in common, are that they are
either secondary side filter caps on switchers, or located right next to a
component that runs hot. SMPS designers seem to have something programmed
into their genes, which compels them to do this ...


LOL ! I had a similar problem with a layout guy. He loved to crowd all the hot
items together. In one case we even found that a certain power diode would after
extended operation virtually 'weld' itself into the tiny PTH he'd provided it
with.
