I'm using a 2-axis gyro chip in a design and the largest package pith I can
find is 0.5mm pitch.

I have a solder paste dispenser along with a hot air setup.  The problem
I'm having is that the solder dispenser puts out too much paste on the
shortest time pulse setting.  My footprint has extended pads in the hope of
solder prepping the pads, place the chip then going around the outer pads
to reflow the solder (with the smallest soldering iron tip) but it is so
small and the chip is just not sticking.

Any suggestions?
