This has got to be the coolest mod I have ever seen! Anyone know which caps I would need to get and maybe a how-to guide and/or diagram?

the problem is
his mobo died
poor guy heheh

Serious!? Damn....

I hope Intel uses all aluminum caps for the Bad Axe 2

mobo is ok several days ago , due to my fault, shorted 2 points

any improvement in overclocks Victor?

Are those Sanyo Oscon's you have used?

I bet you had to drill the board to clear out the solder, multi layer boards are a real pain to desolder.

Why is a Multilayer board pain to solder? cause its not the layers.
Its the way they solder it, they almost hard solder the components. Thats why its so hard to unsolder them away.

Multilayer boards use this technologi and it does not make it harder to solder:

The walls of the holes, for boards with 2 or more layers, are plated with copper to form plated-through holes that electrically connect the conducting layers of the PCB.

Though soldering all those surfacemounted caps must have been a pain in the ass because of the little space there is around them.

Single layer boards did not typically have the complete in hole plating, that was my point, that plating makes it very difficult to suck the solder out, the conventional single layer boards were far easier to rework because of this. I'm sure you have an electronics background. I used to work in pcb assembly for Texas Instruments and have performed rework with pumps and braid. The thru hole plating is only really required for multi layer, for single layer there is no point.


I have a few pcb's here that are dual layer, even using conventional soldering iron methods for assembly, for de-assembly the solder is a real pain to get out due to the complete thru hole plating. Often you have to heat the legs of the device whilst pulling it with pliers from the other side. Once the device is free the hole fills up with solder, meaning you either need a very good pump and steady hand with delicate operation (to avoid pulling the whole plating out), or a very fine drill. Flow solder machines often pre heat the whole board to get a better joint, solder specs do vary, but melting points for most solder fall with the required range. The absence of lead has made soldering work/rework a little more tedious

We made the same point in different ways that's all.


From the face of it he's only replaced thru hole caps..

Oh, I see. (Feeling a little red on the chins >_>)

I have just never had any problems with getting it out. Then again I have not soldered as much as you have

That's cool bro' we all learn from each other,

I guess some of the boards (for audio and discrete regulated psu's) I have worked with can be a real pain.

One of the best methods I've found for sucking solder out is braid soaked in flux, but as you said component spacing makes this very difficult. Easiest is a dremel with a very samll tungsten drill, just drill away once the device is out.

I had to adjust the hole on a dual layer PCB I made at school. It was 0.8mm and I needed 1mm for a Variabel Cap. So I just took a 1mm bore and drilled the hole with the bore in my fingers and it worked. So with the holes in the pcb maybe you can just lay away the Dremmel.

Il try this later today with an old motherboard ^^
