bulging caps and how to fix 'em
hello all, just wondering about this..someone gave me a box with
ahtlon1900,768m ram and so on..They said it was very unreliable..random reboot..bsod . I suspected bad caps and sure enough a fair few were bulging on the mobo..I've read on the net about replacing caps and how fiddly it is..having to get the solder out of the holes etc. but just for the hell of it i yanked one of the caps out with pliers and saw that the 2 1egs were left in the mobo..if i just soldered a new cap to these legs would it work?.. |

Fark, wota butcher. if i just soldered a new cap to these legs would it work?.. Probably. |

Yes. If there's not a lot of room around the CPU though, get sdome veroboard, soder the CAPS in that and make some flyleads up from the veroboard to the old CAP pins. -- Conor Light travels faster than sound.

If you could. Yes it would work. The real way it to use solder wick braid and a solder sucker to clear everything out of the holes. I have done this before. It is not easy and takes a long time. Using two soldering irons, one top and one bottom helps. |

Probably best to just find a compatible replacement board for far less headaches and labor...unless, as mentioned, you'd just like to try it out for learning purposes.

If they are _proper_ crimps, of the correct size, they should be alright. Crimps are widely used, and "wrap around" non-solder connections (using square posts) were used in UK TV sets reliably.

Using two soldering irons, one top and one bottom helps. Often if there's room, it's easy to clip the component leads leaving the wire ends soldered in the circuit board. It's then easy to melt the solder and suck the solder and wire up with a solder sucker device. This will usually clean out the hole also. On stubborn holes, using solder wick you can clip the solder wick end on a diagonal to form a pointed tip of braid. Stick the point into the hole and proceed as usual to wick up the solder. Don't rip anything that doesn't want to just slide out. You'll probably damage the thru hole plating and that can cause problems with connections to interior PC layers. Probably not a big deal with those caps. |
