why don't buy new motherboard? it's quite cheap nowday.
Anyone?
I'm hoping to borrow the use of your soldering station to replace some capacitors on a motherboard... I need a soldering station that can reach 450 degrees Celsius.
Will pay of course.
PM me please!

I have a soldering pot if you don't mind coming over to my office. With a soldering pot, it will be easier for you to replace tin cap capacitor
Else I have 2 soldering station for you to use too
True, but the original poster might need interface slots and/or ports that are now redundant or missing altogether in new mainboards. Still, I wished I had the skills to replace a blown caps.Originally Posted by felix_fx2

I happen to have a thunderbird board with a 1200 MHz. You need ? Free

I can imagine ISA slot right now

Hi guys,
Thanks for the offers! But I managed to get them done myself using a handheld soldering iron.
Here's the story for records.
My friend's motherboard started rebooting randomly for no reason, so I went over to his place to investigate. I noticed some bloated capacitors. You can see clearly that they were bloated as the top was bulging out.
So I did some searching on the Internet and found this website: www.badcaps.net pretty useful for tutorials and guides on how to replace your capacitors (they even have a online store!).
I took his board back home and tried to desolder the capacitors first. It was hard work! Because of the unleaded solder they used for RoHS compliance I guess. Basically what you have to do is to have a soldering iron that can go up to 200W (I bought a goot TQ-95 soldering iron). The trick is to leave quite a bit of your own solder on the iron's tip and press it to the solder joint on the motherboard for perhaps 5 minutes, all the while pushing on the capacitor's body so that one of the legs pops out and you can proceed to do the other leg. I spent 2 hours just removing the capacitors. Tough stuff!
Here's the board with the capacitors removed:
OST capacitors, commonly mentioned on www.badcaps.net as faulty ones.
Then I went to Sim Lim Tower to source for the capacitors with the same ratings (1800uF 6.3V in my case) but all they had were 1800uF 18V ones. I bought them (you can replace your capacitors with higher-rated voltages, never lower-rated ones), thinking they should fit. I was dreadfully wrong. I kept them and ordered the proper ratings online on ebay. On hindsight you could have ordered them from RS Singapore, a Singapore-based electronic component online store with free delivery I think.
Soldering the first one in!
The holes were a tight fit... so I ended up having to use lots of solder to melt the remaining residue in the holes while pushing the capacitors in by hand. Took two hours. This is horrible work of mine... a skilled solderer would have done much better.
All done! And the board works again! Amazing!
Can I make a guess that the brand of this MB is Gigabyte?
Oh well nice "hands-on" work any way even if it is not pretty which hardly matters since the motherboard should be out of sight anyway. Good experience no doubt of being able to fix stuff and getting them to work again.

Haha it's an old abit motherboard.
True. Actually after the capacitor's legs were snapped off, the motherboard looked as good as new.Oh well nice "hands-on" work any way even if it is not pretty which hardly matters since the motherboard should be out of sight anyway.

That's good to know and thanks much for the "pictoral". It really gives a much clearer idea, the amount of work and skill involved. At least it tells me the difference between a capacitor and/or resistor!!
You want to further practice new found skills with another mainboard? I have a Asus P5WD2 Premium, I think, that needs CPR!!

Hey Ron,
What's up with your Asus P5WD2 Premium? Bloated capacitors as well? If you're willing to foot the cost of the capacitors I'd gladly repair it for you. It's the school holidays for me currently. BUT they have to be electrolytic capacitors and not metal capped ones.
Here's a better pic of bloated electrolytic capacitors:

That mainboard has some caps with indigestion... quite bloated and I have no idea how to differentiate eletrolytic from capped... duh... I had a friend look into it but don't think he has even touched it due to tight work schedules, so I might just collect it back one of these nights.
Is the repaired mainboard working as it should now?

Oh differentiating between the two is easy.
Electrolytic capacitors
Solid metal capped capacitors
I know how to replace the electrolytic kind but I'm not too sure about the solid kind.
Yeap, the board is working as it is. No problems reported by my friend. I spent about $5 for the 9 capacitors shipped from Hong Kong. I'd order them from RS Singapore if I ever do capacitors again though.
