This type of package is much easy to manually solder than it looks, because of the solder paste cohesion with the pads and the package is creating a sort of auto-positioning if the solder is correctly melted. The true problem is the PCB which requires a lot of thermal vias to evacuate the heat into the ground plane and heatsink.
