So you don't know how to use one properly. That shouldn't guide the use
of other people. You don't poke the point in, you lay the side of the
cone on. Full heat to single pins, no problem. Turn 90 degrees if you
want full heat to multiple pins. If there's no soldermask, your method
can get very messy very fast. Even if there is soldermask, it has
limitations which the properly applied fine point does not. If you use a
fine point improperly, you'll do about as well as people that use a wide
tip improperly. By all means, keep doing what you like, but your one
true way - isn't.

Most of the time for gullwings you can apply enough solder to bridge the
pins then wick up the excess solder quite easily. My method is simply to
clean the tip each time and the excess solder wicks up on the tip. If you
presolder the pads then it generally isn't an issue either way.

BTW, a similar approach works for QFN's but is a bit more difficult.

When buying parts for prototypes buy a few more of all the small parts so you
can just get a new one when one pings off (it doesn't take a lot of force when

can just get a new one when one pings off. (It doesn't take a lot of force when
opening packaging to do this).
