This simple tool will change your life. I was lucky to learn how to solder surface mount from a master. He had crafted a tool very similar to this for himself and used it daily. The design is simple, a weighted pin is attached to a piece of round stock and this holds the part down on the board. Using this tool I soldered an entire surface mount board with no errors on my first try.
When you assemble the tool make sure that you push the bolt through and thread the nut first, because you might bend the threads while filing the tip down. Make sure that the tip has a round point about the size of a standard ball point pen. Any sharper and you could damage/mar parts.
To use the tool just put the part under the pin and go. It’s that simple, no re flow plates or panavises or any of that junk. You don’t need to worry about tip size for most jobs either. Another plus is that the bolt acts as a heat sink so small parts don’t fry.
You see that tiiiiiny little part. You’re welcome.
