I would like to experiment with audio applications using MEMS microphone. The problem is i cannot think of a way to solder these microphones on a pcb as PCB prototype manufacturers that i know won't do re-flow soldering for a single board.
One option would be to buy a hot-air reflow station, e.g. Sparkfun. Chinese-manufactured ones are reasonably inexpensive, and some are of good enough quality for prototype/home use.
You might also consider dead-bug prototyping with some 30-gauge wire or so and a good quality hand solder with a fine tip. This involves turning chips upside down and soldering pins directly to parts or using wire, without necessarily using a board (you can solder the wires to a PCB or a copper-clad board of some kind if you want). This can require fine wire and a lot of skill for parts with small, fine-pitched pins.
