Okay, we think it's questionable when people say they have no problem soldering QFN packages, but BGA? Granted this chip has far fewer balls on it than many, but it's still quite impressive that [Xevel] was able to solder this BGA breakout by hand (http://www.xevel.fr/blog/index.php?post/2012/11/10/Deadbugging-fine-pitch-BGA) .

The chip you see above is a TMP006 infrared temperature sensor from TI. [Xevel] picked up the part but didn't want to break the bank when prototyping by buying a proper PCB to host it. There are only eight conductors on it, arranged in a grid with 0.5mm pitch. That didn't seem to scare him off, as the video after the break shows him connecting each to a conductor on a hunk of stripboard.

[Xevel] mentions that this is a dead-bug style project. Usually you glue the part upside down when using that technique, but it needs line of sight to get an accurate temperature reading so he first cut a hole in the substrate. We'd bet he's using wire-wrapping wire to make the connections. It's a very fine solid core wire which is perfect for this kind of work.
