You also need a finer solder tip if you want to go smaller than 0402, but its a nice idea for some medium size parts. 0201 and 1005 components are rare, but new cellphones have em if you ever try to fix one. BTW fine pitch usually refers to IC's, QFP's, BGA's, and connectors. http://www.youtube.com/watch?v=5uiroWBkdFY&feature=fvwrel Good drag in the middle of the video. Use solder wick and flux to get rid of bridges. I use a flux that has the consistency of water though, it seems to work better. I don't hand solder much though myself, just try to let our machines put onto solder paste and cook. 46 seconds per board with 517 parts last night (a video card.) :sad: Well that won’t really work for smaller than 0603 unless you whittle down that pin, even then tweezers are probably better.

Anyway, for heat sinking it's a nice idea, if you need it. Lol, sorry but your “master” clearly doesn’t know how to solder SMD very well.

Apply small amount of solder to one pad, preferably a pad that is on the side of your iron hand (right hand for me) 2. Grab SMT component with tweezers, hold in place 3. Heat the pad with pre-applied solder, then apply solder to the rest of the pads. Make sure to add a little solder to the original pad. This method is quick and easy. You can pre-apply solder to a pad for each component on a PCB, and then literally do hundreds of components per hour, even IC's. A much quicker way to do it:

Just to verify some dimensions and such: Roughly 2" diameter dowel segment for bottom, roughly 1/2 to 1" diameter dowel segment for top, 6-32 bolt and washers? (Among other things, I'd like to build this beauty myself and possibly provide a parts list to the mailinglist as a whole with pointers to your simple instructions) Very interesting take on an “Eleventh Finger” SMT holder (there’s some ongoing discussion of these on an amateur radio mailinglist I’m on focusing on an SMT-heavy transceiver kit).
