Soldering Capacitors to Motherboard

[[email protected]]

I had 5 bad capacitors on my Gigabyte motherboard that was well out of
warranty. I got all of them desoldered and ordered new caps. The
problem is that the new ones are bigger than the old ones. For me to
solder the new caps in I will have to leave about 1/16"-1/8" of the
lead exposed. It will not be able to sit on the board as the old ones
did.

I figured I could use some heat shrink tubing around the base of the
cap to "insulate" the leads from anything coming acrossed them and
shorting them out.

My question is: Is it acceptable to solder these to the board with a
small amount of the leads exposed?

Thanks for any help.

We used to change caps on motherboards a lot, if its only a few mm then it
probably wont do any harm, We never tried it though! make sure you fit
quality caps 105deg at least. If they are not the same spec cap or better
then you could have stability problems at worst.

I'd say yes, electrolytic capacitors have relatively high internal
resistance compared to other types of capacitors I doubt that the excess
leads will do any harm.

I added to some caps on my MoBo under it additional block ones of
100nF; the result: temperature drop on main electrolitic ones from 5
to even 10°C !
