Don't flood that much solder onto the pins, that takes way too much time to 
clean up and may be outright impossible to fix on a more densely populated 
board.  The "right" way to do that type of work is to apply flux liberally 
after having tacked down at least two corners, then steadily drag a blob of 
fresh solder along the pins.  The solder blob stays on the iron, it takes just 
a little bit of practise to learn the best speed of dragging (too fast and the 
solder won't wet the pins, too slow and you get bridging and puddling).  If 
you have a little bit of bridging here and there, let the part cool down 
before cleaning up.  I never use solder wick for that.  If it's a multi-layer 
board with lots of metal you will need to warm it up on a hotplate or with an 
hot-air gun set to 120…150°C.
