This Nichicon PL 4700?F/10V part as well as all the
Chemi-Con SXF parts
have
certainly leaked in almost all the H7826 PSUs I have
(which have been the
worst in this respect), and consequently the PCB has become sticky in the
output filter area. Beware that in addition to the output filters there's
another
SXF part just next to the input filter capacitor;
it's visible on one of
your photos,
next to the lightning bolt sticker.
Hello Maciej,
That 4700uF/10V capacitor is really hard to remove, it seem to be connected
to large planes on both sides, which suck all the heat away. I have a
suspicion that it may have leaked from the underside as the area around it
is certainly quite dirty in a way that suggest the dirt has stuck to
something.
Did you manage to remove this part without destroying it and without
damaging the board?
Regards
Rob
