Hi

 In most cases, I find that heating from one side and sucking

from the other works fine, even for ground planes.

 If I can get the solder to melt at all, it always clears this

way.

 As another mentioned, if it only has a little solder in

it, you need to add solder to fill the hole before sucking.

 Solder wick is almost impossible to use in such cases

without damaging the board ( too many heat sinks ).
