I've just made a breakout adapter PCB for a QFN32 device - the ADI AD8333 Dual I/Q Demodulator and Phase Shifter. Making the PCB was quite straightforward, although the pads are quite small and 0.5 mm pitch. I've posted a pic of the assembled unit in my (Leon's) photos folder. The hardest part of the assembly was getting the pads lined up properly so that I could tack down two opposite corners. Once that was done I applied plenty of gel flux to each row of pads and drag soldered them, a row at a time, using a 1/64" conical bit cartridge with my Metcal system. I haven't got any bridges and the joints look OK. I used a stereo dissecting microscope (X20 magnification). Leon
