I've done some surface mount soldering - things like SOT23 (a little bit fiddly due to the lack of mass), SOIC (so easy!), SSOP (once lined up, easy using the don't-care-if-I-brige-it then soak up the excess solder with braid)
I have a project I want to add Ethernet to - I was planning to use the Silicon Labs CP2200 all-in-one Ethernet chip, which looks easy to use. However, my favorite supplier seems to have stopped selling the CP2200, which came in a TQFP (which looks no harder to solder than an SSOP). Instead they now only sell the CP2201, the same chip but in a pin-less QFN. Indeed, I can't find the CP2200 anywhere, only the CP2201.
Is the only practical method for QFN to reflow? Or has any brave soul hand soldered one of these buggers?
Anyone tried reflowing on a home etched PCB (i.e. no solder mask)?
