Also depends on what IC's (chips) you are looking to work with. DIP's are easy as they are basically just thru-hole (just a little less spacing between the pins). SOIC's.. flatpacks.. the kind where you really need a good eye (with the assist of a mag light/stereoscope/etc) = Choose your tip wisely. The smallest chisel type tip you can find that will just cover one pin OR the round/sharp tips are good for these. Use flux, but sparingly. Prep the pads with as little solder as possible prior to mounting the IC, tack on the upper left/lower right pins to line it up, then go for the rest.
