A relative showed up with this board this evening, so I didn't get a chance to take many pics of it... I snapped a couple quick before pics, but forgot to get one of the whole board, so I can't say what model it was. blah. no after pics; he was very, very anxious to get it back in his computer... it's a 233mhz AMD chip IIRC. don't recall which socket. Most notable features is the board is pretty small, and has both AT and ATX power sockets, to be used with either type of power supply.
Board had been partially recapped a couple years ago, when only two caps were buldging... this time every other cap except those two was replaced.
Caps present:
2 replacements, 16v 1000uf. don't know what the board came with, as this was the first time I'd seen it.
5 Tayeh caps, 6.3v 1000uf. Four vented, two out the bottom and two out the top, and one very close to venting.
Nope, no others. board only had a total of 7 caps, except for teeny tiny electrolytics 100uf and less.
Replaced the 5 caps with nichicon 1200uf 6.3v ones.
Board was HARD to solder. never had one that was this much work. Must have frigging thick traces. I gave up on my 45W pencil tip iron and got out my 140W gun (the one I've soldered 6awg wire with), and STILL couldn't melt through the vias in under 30 seconds. Vacuum desolder couldn't get them clean, had to use the 140W gun and a needle pushed through, and even then I couldn't keep the needle hot once it touched the traces.
Symptoms:
IDE corruption, windows refusing to boot due to being unable to read files, occasional random reboot.
After recap:
Windows boots and works perfectly.
Photos:
By the CPU: (the blue one is one of the previous replacements)
The caps themselves: (taken from the above image, but cropped instead of shrunk)
Off on the corner of the board:
Between the agp and onboard IO:
I didn't get a pic of the 5th cap or the whole board, as he really wanted me to get to work fixing it...
Lesson learned: Some boards absorb heat remarkably quickly. I barely got this one with my 140 watt gun. I don't want to get out my 275 watt gun for a motherboard! Other boards I've done, my 45W iron was plenty, and my desoldering station was able to clean through the holes...
