[Boatanchors] Multi-Layer PC Board Component Replacement

[Mike-WE0H]

I use a 50w iron with the proper sized tip and heat & pull the cut off 
leads out of the holes then desolder the holes. You should be fine. Use 
a regular vacuum desolder iron if you can. Just don't apply any pressure 
to the board. Use a bit of liquid rosin on the leads before you start 
the removal and sucking solder. It should transfer the heat plenty fine 
then. You also can take a heatgun and pre-heat the board a bit. Not 
screaming hot but warm to the touch. It will desolder real nice that way.
