Well...

I do it differently...

1. Wrap main PCB with some Aluminum foil - leave conn. uper side un-covered.

2. You can apply pretty much heat on uppper side as you want. (do NOT over step it - I dont mean that you can use welding torch!!!)

From 1-9 heat scale - up to 4.5 is sufficient.

3. Heat until you can remove it with tweezers.

4. Clean pads on PCB with solder wick and wide solder tip.
(all of them - that means conductive - on backside of conn., as and constructive - which is grounded and more of mechanical nature - hold's connector to a PCB)

5. If recall corectlly - you'll sometimes have trouble with front two trough-hole mechanical pin (after removing conn. - solder will cease and fill the hole in which you soppouse to insert pins from a new conn.)

- I usually solving this by forcing sharp tipped scalpel trough it, and little by litle wide-ing it

- if is too much solder in holes - just press scalpel and apply heat with solder (wide tip) from other side of PCB.

6. Put new conn in place - ensure that is correctly placed and solder it with regular solder (apply some flux on el. part of conn., it eases soldering process)

Also think, that it can be removed with some regular solder iron (50w) applying solder on top of it, and heat until released.
