To do a DC Jack Replacement I am currently using a 40W Soldering Iron from Home Depot and a Desoldering Pump from Radio shack.  I manage to get the job done but it takes hours to complete.  I think it is because of the tools I am using.

Does anyone have suggestions on the correct tools I should use in order to get this job done fast and without harming the system board?  Please provide Make, Models, and other specs if needed.

Thanks...I've used this guide before (he makes it look very easy).  

His soldering iron is 50W set to 800-850 Degrees F.  Mine is a 40W with a max temperature of 865.  I guess it is possible that the his soldering iron is a better quality and gives a more consistent temperature on the tips.

However, I would like someone with first hand experience to give some feed back on the issue.  I want to make this process as easy as possible and if I am going to invest in the right tools, I'd like some experienced suggestions.

i replaced capacitors on a mobo, and used a 60 W temp controlled Weller soldering iron.
i found it nearly impossible to melt the solder, and used an old 100 W iron for it.
This melts it quickly -  so be quick also, and don't let it heat for longer time than necessary.
as a matter of fact, i have a DC jack to replace on a compaq .
if i have time i'll post my findings here

This is a little off topic, but I think the solder you are using is too thick.  60W should definitely be able to melt the solder for small electronics.  I have a 25W soldering iron that can melt my solder.

Still need advice on the De-soldering process.  This is the time consuming part of DC Jack replacement.  Anyone have some tips?

A 40 watt soldering iron is hot enough to do the soldering and de-soldering most of the time.

At times some solder points have are just stubborn to melt or solder due to to oxidation
Use a  little bit of soldering wax or paste,  it will help to melt the solder quickly.
The paste is also good for soldering contacts which are difficult to solder.

Solder paste/wax cost about $2 and come in handy for difficult to solder/de-solder points.

After reading a bunch of forums and tutorials, I purchased a spring loaded solder sucker from ebay for $5.  I am going to try another DC jack removal with this tool to see if it helps.  It seems that this is the only tool that other people have that I do not.

I will post my results, and appreciate any other comments.

it's not my solder that does not melt  - but the onboard solder...
and i have 30 years experience in soldering  - so i think i know how to do it
