That's why its usually a good idea to try and get the flux to go though the PCB socket, rather than just around it. I'm not able to do it myself (not quite that good at soldering), but I know of people that are good at it, and they get it to vacuum through the PCB hole.

The trick to that is a very very clean connection of the solder joint, plus the right amount of heat. Too hot and it won't work

Yep, clean tools, solder, and clean copper connections is what makes it easy, getting it cleaned properly, that's a bit difficult on some boards.
