[Coco] An inside look at producing the COCOVGA

[Dave Philipsen]

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.
