>soldering a 100 pin TQFP chip doesn't seem doable. Soldering TQFP or PQFP is not a problem... as long as the pins are straight and the board well made (ideally bearing tined soldermasked pads) Solder and adjust 2-4 pins then just roll a solderiron controlled miniwave of fresh solder (/w internally flux) down (using gravity) each side finally inspect with microscope or magnifier...
