    New capacitors for Motherboard
    « on: September 19, 2008, 07:56:25 AM »
    Is it possible to replace the capacitors on a Motherboard? If so can Solid ones be used (like on the gigabyte boards, and where can they be obtained from etc??

    Reason is we have a number of ex-corparte machines that have blown caps, otherwise working, seems a shame to waste them for the sake of some caps!

    Wondering a bit what you mean by ''solid'' ones!

    With polarized caps main thing is to stay at or better than the old cap's rated op voltage, plus of course value - altho as larger electrolytics are more smoothing than time constant a slight increase in value may not matter IMO.  And, as xavier reminds us - care with polarity when replacing.

    Non polarized, if any there and these anyways not so prone to fail - try and use same type .... polycarbonate or other.

    Final thought - while electrolytics can and do fail - maybe due to insulation breakdown inside - there are occasions IMO where failure may have been brought about by a failure elsewhere - so, well worth very detailed inspection to look for PCB track fusings/high temp signs - and mini resistors etc.
    Ain't technology great - until it goes wrong!
