I have began working with SMD chips and especially with my favorite QFN package some time ago, and i have already manage to radically reduce the size of my PCB to minimum, thanks to the tiny footprint of those packages. Slowly i began replacing my titanic through-hole parts with SMDs (whenever possible). One problem that arises with QFN PIC packages is that the microcontroller must be programmed after being soldered to the PCB. I know that there are QFN sockets that i can use to make a QFN chip programmer, but they are still very expensive to get, almost $100 each.PIC ICSP Instant SMD Connector with Pogo Pins - [Link]
