   Correct.  I usually tack the opposite corners for positioning the 
chip - with tinned pads, there's more than enough solder to hold the 
chip down in the correct position before you flux all of the leads and 
sweep the iron.

   I've found that it doesn't go quite as quickly when you have a board 
without pre-tinned pads, but it's still way, way easier than trying to 
solder each lead, individually.
