Desoldering this?

Hi victornor
Looks like you have burned the PCB. If this is not the case you can still manage to remove that solder. Grab a soldering iron and melt the solder there. Now, use a tweezer or a multi strand wire or a resistor end and try to swipe them in the space between two traces.
Warning: be careful while doing this as resistor or wire or tweezer might become hot quickly after coming in contact with the soldering iron.

Thanks, i'll give that a try.

I was worried if i had burned the pcb, but i hope not

No way to fix it if the pcd is burned, right?

Don't worry, I have done this so many times and have also cleaned up all the mess as well. You can do this.
Please mind following:
Do not touch soldering iron for long time.
Do not grab resistor/wire/tweezer other end with bare hands it might get hot quickly.
If its not coming off between spaces try de-soldering wick few more time.
If all above fails, melt some more solder again on the traces and try wiping it again.

Be careful of soldering fumes.

Try wet(not too much wet) sponge to wipe. be careful to clean the water after doing this. You can use hot air to evaporate water traces.

Even if it is burned there might be other ways to use it. Don't worry

I think the pcb is burned, so no use in those pins.

I've also thought of a way to get around the problem anyways

I've only damaged the power pins and not the data pins, so if i really wanted to, i could get power externally.

Thanks for the advice, i will give it some more tries

I can't tell about the PCB(burnt or not) but you are absolutely right about the other way to power up things. But don't really use any external power, you do need to find the way to power things (HDD or DVD-ROM's etc) connected to that Sata port from that motherboard itself. Otherwise, there might be ground issues.

Good Luck

Do you think i could get anything out of those pins, or should i find a way to power it from the motherboard, without the pins/traces?

That you need to check after removing solder connections between the pins. If it does not work then only move to the other way. But first try to remove that shorted solder connections.

If the tracks going to the pins are not broken, it should be possible to clean the pads. Apply extra flux before gently using solder wick. The flux will make the solder migrate onto the pads and away from the PCB. In fact, just adding flux and re-melting the solder may be enough to clean it right up. When using solder wick, as MUDZ indicates, add enough solder to get good contact with the solder wick. Do not apply too much heat or mechanical force or scraping - this will lift the pad or break the track.
