More and more AVR's are coming out in this nifty, tiny package. I'd really like to use it in some one-offs, but I'm concerned about being able to hand-solder it to a PCB (I don't mind getting one fabbed with a solder mask). I've heard it's not that hard, but I haven't been able to find any details of the procedure. Anyone have any experience with this? Thanks.

FWIW
I might add that instead of tweezers, I took an old vacuum pump (found at a junk store) and then to the hardware store for some plastic tubing. Go to your doctor and ask for a 23 gauge needle (or thereabouts) and tape it to the working end of the tubing. Larger gauges for smaller parts, smaller gauge for larger parts.
This works great for picking up tiny resistors, and also for large M128s.

... I should have mentioned I already read the article. The author says, "MLF is hard to solder though, it is really designed for wave soldering or a similar process. It is very small, but it IS possible to solder it by hand," hence my post. What makes it so hard it that the pads don't protrude from the sides of the package. Plus, they're almost impossible to see.

johnday An MLF package is best done in an oven. Use solder paste or cream then reflow the solder in a toaster oven. Works rather well, but you need to be careful with dispensing the paste and with slowly warming and cooling the board. Which means it is best done away form meal-time!

... and what success rate have you had? What temperature and duration did you use?
