I am trying to solder on a new capacitor near the CPU. Unfortunately the existing solder will not flow.
Is the board coated in something or is there a trick to these boards? I have a fine tip iron with adjustable temp. Can some one tell me what it need to do to get this done? Thanks.
Is this a good question?

Read this tutorial for pointers.
The motherboard will start to degenerate when the temperature reaches 425 degrees F. That is the binding that the manufacture used when the motherboard layers were pressed together will start to separate, if the separation happens to be where there is a pass though then the motherboard is effectively destroyed. That is the reason for the heat sink that will absorb the heat that will spread while you are soldering.

Peter, you have done this before? You are using flux? You are placing solder on the soldering tip before ?

I've soldered before but am still quite new. I haven't used flux on this board, yes I had solder on the tip. I'm just trying my hand as I have a water damaged logic board and this one with the busted cap. I figured I'd have a go replacing the cap but had trouble removing it. I have some lead free flux, will that be sufficient?
