An approach I found quite efficient for occasional DIY of QFN parts on home-made PCBs is to apply a generous amount of flux to the PCB's pads, coat them all with a thin layer of solder, clean up with alcohol, add flux again, place the component, then solder the component's pads one by one while tipping a tiny amount of solder on the traces leading to them. The solder under the pad will liquify and help to make contact. It's not perfect, so you still get all the joy of testing. But it doesn't require anything but the most basic SMT-capable setup, i.e., a soldering iron with a fine tip, solder, flux, and a good desoldering braid. - Werner _______________________________________________ Openmoko community mailing list [email protected] http://lists.openmoko.org/mailman/listinfo/community
