I am using this to practise my QFN soldering. Both the SAMD in QFN32 and 5 resistor array are bit challenging to solder. However the classic way is still effective. Tin the pads. Apply the flux. Align the component. Use the soldering iron or a hot gun. That's it. Check this video, https://hackaday.io/project/6580-smd-soldering-made-easy
When you start the soldering as a hobbyist, desoldering is one thing you need to learn sooner or later. Then both solder wick and a hot gun are your friends.
With the hot gun, you will start to use solder paste. Then stencil, and a baking oven or overflow chamber. Perhaps a microscope in the end.
