      That tool is great!  I have been wondering how to do something like that and the answer is as close as my wardrobe...   Also, my SMT skills took a huge leap

        That tool is great!  I have been wondering how to do something like that and the answer is as close as my wardrobe...   Also, my SMT skills took a huge leap forward when I started using  liquid flux (I have 100ml bottle but a pen would have beeen just as useful).  Rather than using a bottle or syringe to apply the flux, I just dip a dental pick into the bottle and dab a bit on teh board, then use the pick to  manuever the parts into position.  Also, I now have a roll of .015 solder  that works better (for me) than the .020 along with an inexpensive Velleman temperature controlled soldering iron.
