Soldering BT module


Greetings! I bought 2 samples of Laird BL654PA(the long range version]. I want to make a simple board suitable for my needs and test the device. But I have a problem soldering the module to the board. The pads are so tiny. I`ve tried to apply tinol to all pads and use hot air from beneath the PCB - many pads don`t solder well. I don`t think stencil will help because of the size of the holes. How do you do this?

A stencil might actually be good. I don't think hot air would cut it on that land grid, I think something more uniform would be better like a hot plate or an oven.
