motivated by the Nuts and Volts article I went out and bought a $29 Black and Decker toaster oven, and then from Digikey some of the syringe solder paste ($40, you need the syringe plunger too). I am using something which appears like a dental pick to apply a small dab of the solder paste on the pad, then carefully place the device on the pads using a fine tweezer. I find it conventient to squeeze a bit of the paste onto the ground plane of the board. toast for a couple minutes at 450 degrees or so -- something like 2 to 3 minutes -- the only problem seems to be that if you remove the board too quickly the parts can slip around a bit when the solder is hot. if you are careful the process works beautifully. i've posted this on www.diyaudio.com, so far no takers. jack
