Thats why you dont want to simply drag solder and use a vacuum desolderer to remove the excess. Because it mashes the solder down and creates shorts.

Best way: Use an SMD291/SMD294 flux from chipquik. You can lay down a tiny bead around the IC, and wet your tip with solder. slide the tip on the chip as you were doing, The flux will allow the solder to reflow properly and evenly. Remove any bridges/excess with solder braid! Then the removed areas, re-touch with the tip to straighten the flow. They will look machine assembled/soldered this way.

this is the best way to do it outside of using a stencil, and reflow/hotplate.
