What temperature are you using? Do the other components become fragile (movable) at that temp or do you run the plate below the melting point for the solder then use some kind of local heating? |
That is simple, identify melting temperature of the solder (take a small amount and put it on heat plate while raising temperature) then use for entire board.
And, yes everything becomes loose, so carefully remove the part you do not need and put new one in. (Solder paste or Flux and solder with capillary effect will make your life easier).
