you think comma's would help?

bad, bad, capacitors?

Currently I'm fabricating a list based on
http://www.badcaps.net/forum/showthread ... 88&page=10
and the wealth of info here:
http://capacitor.web.fc2.com/

Will publish later.

The only solution to bad capacitors is to replace them.. with better-quality units. Capacitors are made in many forms and types and voltage/temperature ranges.. to suit the need. Heat is the major enemy of capacitors. The "dry" type (ceramic) seldom have problems.. unless given a high jolt of voltage. The common electrolytic type will allow gaseous discharge of its electrolyte liquids at high temperatures.. causing fatal faults after a long use time. Also, a formula for the electrolyte must be "friendly" to the materials used to make them.. otherwise corrosion causes rapid internal failure.
Whenever replacing faulty capacitors, use only the same Farad rating. The voltage can be the same, never lower.. but higher is acceptable. The temperature range is to be the same or higher also.. never lower.
With data-transfer or timing circuits involving capacitors, the same value is required.. or performance will be severely affected. For capacitors used in DC power filter circuits, a higher Farad value might be acceptable.

To compile a database of problematic types can take a long time.. unless someone is tasked with that ominous chore by itself. Not a 'career' I would want!!! Image

Which is what these people did:

Just a matter of how good your Chinese is or how well you are in understanding the Google translate dialect of English... :)

you could add these boards from my personal experience:

Abit VA-10
Shuttle AN35N-Ultra
Albatron KX400-8X

even just sitting there caps bulged and leaked. 3 of the computers i used to Fold with.

Likely they were the victims of the "bad caps" formula.. and time does have its effects with corrosion internally. When you note the exterior signs, when it is then critical! I, too, have had some "new" motherboards develop bad caps.. while in a suitable environment, in sealed pouches!!

New addition to the "bad caps" gang! A friend asked me to look at his old system, with an ECS P4VXAD mobo.. locking up and rebooting. Guess what.. one bad cap behind the CPU socket! But only one of about nine showed a domed top. It was branded "Elite", 3300 mfd. at 6.3 volts.. 105°C rated.
Only running a 2.8 Northwood at 400 FSB, and is used only for Web browsing and minor needs. Will have to do checks every few months to see if more go bad.
