Nice video! I have used the drag soldering method too and the more you
practice the better you get. I went from doing .5mm pitch back to a
.8mm pitch QFP and it was like child's play! A few years ago I would
have never thought it possible that such fine pitch chips could be
hand-soldered down with such ease and so few errors.
