I was wondering why vertical mounting electrolytics have like an
indented cross on them.
To release the pressure and gunk under fault conditions (or bad
manufacture).
The reason I ask is because there's 4 largeish
one around my CPU on the motherboard and they have all split open,
along the indentations.
Oh dear.
A: How old is it ? (from date of manufacture)
B: Can you read what brands they are ?
C: Has your PC sharted behaving strangely yet ?
D: What brand mobo is it ?
E: Replace ASAP with well-known brand, low ESR (switching) types.
As Graham says, but be aware that unless you are a *very* experienced
solderer, and posess the right desoldering equipment, you will struggle to
do the job. These are some of the very worst bitches to get out of a board,
that you will *ever* come across. And then some.
