Pad repair

Postby tahitian954 » Tue Feb 05, 2013 3:04 pm

Been saying for a while that I was going to try a pad repair the easiest way, been reading so many threads about pulled pads I thought this may help some of you guys out, lets face it, if you have pulled pads, then you have nothing to loose!
I took a gpu and picked a ball off the test point corner to pull the pad

Then applied some of this to rebuild the pad

Left 24 hours then re-attached ball, tested with meter, all good!

I myself was skeptical, but it worked, proof is in the pictures!

So you just need to put the conductive paint into the dead pad hole and that should repair it?

Is there anyway to test if the pad is ok on a xbox motherboard?

[quote="jamesfreddie"]So you just need to put the conductive paint into the dead pad hole and that should repair it?

I was testing this out on a gpu as I didnt have any pulled pads on a mobo, and it was easy to remove a pad from a gpu. I simply picked a ball off with a pin which took the pad with it no problem. I wanted to be sure that the paint could take the heat needed to melt the leaded solder ball, this was the part which I had my doubts about, I thought it would just burn out or melt, but to my surprise... it worked!!
I would say that provided the trace on the mobo has not been damaged, then there is no reason why this should not work on a mobo as-well. Its an intricate job, but that was the first time I had ever tried it, and I found it quite easy. Just need to make sure it is level and any excess cleaned off around the edge so the ball is not tempted to wander during attach.
The pen I used was a cheapo version of the maplin one, but I wanted to make sure it was going to work before shelling out £20 for the maplin pen. The pen I used states ONE USE, but I sealed the end so I can use it again if I ever need it. It was 0.2ml but it takes nothing to rebuild a pad, so even that amount will last me a while if it doesnt dry out!

I forgot to mention in the tut, all credit for this repair goes to fersy who came up with the idea.....not me.
I wanted to test it out as there were so many posts on here about pulled pads, and no simple fixes like this. So I bought a pen for the aid of helping others, and in the name of experimentation, to give something back to the forum.
It worked, and in my opinion is a very easy fix!

Guys just to let you know i bought a maplin pen. Not easy to use as the tip is too big for accurate placement although it can be done. Used the pen once and then clogged up couldnt use it again. So i ended up cutting the pen to use the solution inside.... Found it much easier applying with a needle.Just for info.

I did wonder about the maplin pen tip...the one I got has a needle end which was almost perfect pad size and wasnt expensive at all!
Had also thought about applying it with a pinhead for more accuracy!
