Replacing Bad Motherboard Capacitors
Need to replace some bad caps on a socket 7 motherboard.
While it is old would prefer not damaging or destroying it so am wondering if any has cut off the bad caps leaving the leads in the board and then wire wrapping the new cap to these leads. Appreciate any tips or suggestions, especially by someone with actual experience. Thanks Gene OHara |

Replacing Bad Motherboard Capacitors
Two ways I use: Cut off the legs, & leave just enough
to solder on a new part, or use a hot soldering iron, not too hot, & use desoldering tool, or solder wick, or both, & just drop in the new parts. If too many capacitors are bad, it may not be worth it, as the CPU may be bad. Sky. |

While it is old would prefer not damaging or destroying it so am wondering if any has cut off the bad caps leaving the leads in the board and then wire wrapping the new cap to these leads. Appreciate any tips or suggestions, especially by someone with actual experience. Thanks Gene OHara I replaced 12 capacitors on an Abit AMD board (used in an HP Pavilion) These capacitors had a narrower lead spacing than normal - but DigiKey had the correct Panasonic capacitors (not cheap). This Abit board is a 4 layer. Good soldering techniques and experience is mandatory for this work. I pulled out my Pace MBT-250 for the desoldering work -- but even then a couple capacitors proved to be difficult to remove. PATIENCE is a required skill for this work -- if you get frustrated easily -- throw items across the room, etc. -- have someone else work on it. In total, it took me about one (1) hour for desoldering capacitors, cleaning the board of the hardened electrolytic paste from the capacitors -- that had already burst and solder in replacements.
