Re: Stubborn solder won't leave hole!
It's an [url=https://www.badcaps.net/forum/showthread.php?t=14718]Abit IC7-MAX 3[/url]. It all started when I took my PC to bits to clean the CPU heatsink which had gotten clogged up with crud (I usually clean it annually), and I failed to seat the heatsink properly, so the CPU got fried. I got a new CPU for it, but while putting it back together I noticed some of the caps swelling, and a couple had ejected electrolite over the board.
With the new CPU it was still working fine apart from the very occasional re-boot for no apparent...

Re: Stubborn solder won't leave hole!
If I remember correctly it was a Silverline (40 W).
Looks like I did screw up the board during the process somehow. It gives me a beep code that means either a memory or a GFX problem. I'll have to try swapping RAM about a bit more and a different GFX card when I get a chance, but I have a feeling the board is toast....Leave a comment:

Re: Stubborn solder won't leave hole!
That's about how much it cost me
Anyway, like I said, those were the worst examples - the tricky ones to de-solder, and I must have heated up those pads 50x or more
I've attached an example of a better de-solder below.
I do want to get myself a good temp. controlled iron eventually.
I also just realized that the type of de-soldering pump that I used is not recommended for clearing holes - I could have sworn it was! Either way, it's done now.
I also soldered...Leave a comment:

Re: Stubborn solder won't leave hole!
Here are a few pics I got of the more iffy de-soldered holes.
The first two are examples of the most damaged pads, and the last two may have unwanted solder bridges.
I think I may have got away with it... what do you guys think?...Leave a comment:

Re: Stubborn solder won't leave hole!
Job done! 44 holes cleared in total. Now to check the work and make sure no traces have been compromised and no inadvertent connections made.Leave a comment:

Re: Stubborn solder won't leave hole!
Well, after a good night's sleep I tried the de-solder pump and braid again without any luck. Then I remembered I'd seen a paperclip on the floor in our garden store room, so I went and found it. It turns out it was just the right size, and I've just cleared two of the difficult holes!
Not sure if it's stainless, but it works, so I'm happy
Thanks for the encouragement and advice y_not and mockingbird!Leave a comment:

Re: Stubborn solder won't leave hole!
Still no joy
I tried the other remaining holes and it's the same story. It can't be a coincidence. I did leave the hard to get to holes till last. They are all in awkward to get to places that I could not reach with the tip of the de-solder pump, so I'm using a short piece of electrical flex outer insulation as an extension - it fits nicely over the de-solder pump nozzle and gives me an extra few mm reach. It worked fine at first, so I doubt that's the problem.
I may give up on it and try the braid again later on...Leave a comment:

Thanks. Going to try doing the other side too now....Leave a comment:

Re: Stubborn solder won't leave hole!
I did try adding a bit of fresh 60/40, but just to one side of the hole.
I have been fluxing the hell out of my wick!
I'm using a cheap plunger type de-soldering pump from ebay - the kind where you press the button and the plunger flies back creating a vacuum.
The pin idea I tried was simply pushing it all the way through, and back out again, in the hope that it would dislodge any air, so that all the solder in the hole would melt on contact.
The MB is not Pb free as far...Leave a comment:

Stubborn solder won't leave hole!
I've managed to remove all of the bad caps from my MB and now I'm clearing the holes of solder, but there is one hole in particular that the solder refuses to leave. I'm using a de-soldering pump, and most holes clear with one shot. I tried braid, and using a pin to clear the solder initially to see which method worked best for me, but didn't have any success using those techniques, so I settled on the pump as it works great for me.
With the hole in question, I once again tried braid, and sticking a pin down the hole to make sure there were no cavities devoid of solder in there,... -
Re: Should I re-cap my Abit IC7-MAX 3?
Shouldn't the backplate be standard ATX, which is part of the case?
My NB fan also failed, but the board ran fine without it. Even so, I replaced the fan with a standard 40mm fan. Had to bend the heatsink fins a little to get the screws to grip well.
I agree it is a little slow by today's standards, but still useful for me, so worth trying to resurrect....Leave a comment:

Thanks for the reply c_hegge.
I was hoping that would not be the case, but I guess I will just have to bite the bullet and recap the lot....Leave a comment:

Re: Should I re-cap my Abit IC7-MAX 3?
I'm just about ready to recap the board, but before I start, can anyone confirm that the round solder joint at the top in the photo I've attached is not connected to the trace visible on the back side of the board?
I also found another cap (marked 6.3 v 1000 uF A0410 105 degrees) that's bulging, so I've ordered more of the caps that I already got (10 v 1000 uF). There are 14 or 15 more of the same kind on the board, but they all look fine, so I'll leave them alone and keep an eye on them. I don't want to push my luck too mu...Leave a comment:

Re: Should I re-cap my Abit IC7-MAX 3?
Thanks for the advice guys. Luckily I have invested in a new PC so I can continue to surf without risking my old PC/MB. Time to get all the other bits I need to do the re-capping and start practicing!Leave a comment:

Should I re-cap my Abit IC7-MAX 3?
Hello all,
I think my IC7-MAX3 may be on it's way out. Although 2 or 3 caps are bulging and one has leaked, it still works fine. There are 5 suspect caps altogether, all of the same type/spec (1000 uF 10V).
I did find an old thread with discussion about this board here:
[url]https://www.badcaps.net/forum/showthread.php?t=14718[/url]
And this image from the above thread shows the suspect caps:
