I can verify that it is indeed possible.  I lay down xc95144xl-tq100s 
all the time with my iron and some flux and some wick, and I get nearly 
100% rates.  My eyes are not what they used to be either, so a 
magnifying glass and a light touch makes all the difference.

I am sure others on list are even better than I, but I recommend flux, 
place the IC, and then carefully set the board aside to dry. The flux 
will dry, turn into "glue" (as the alcohol evaporates), and that helps 
with soldering.
