In fact i just solder 0402s by hands.
But for QFN and BGAs, you don't know if there are soldered properly. Factorys use x ray inspection machine.

In fact it is just a platform includes all you need to design and do verifications for any audio things. Of course you can make one AI core, or AI voice synthesizer. https://bellard.org/tsac/ or LPCnet from Xiph.org. and then things will go from 1000% to 0%.
By now I implemented the whole FLAC codec(A cpu core+LPC core) and used 20% resources. ::)
running at 50MHz.

all is done! 8)
However some plastic melted......

asmi:
How are you planning to cool this part? It will cook itself in no time once you place any load onto it.

antercreeper:
The FPGA? Maybe u can stuck a heat sink with some tape on it. It's my fault, haven't design holes for mounting heat sinks(no spare space).
It depends on your design.  ::)
For mine, almost no heat generated, about 20~30mA @1 volt VCCINT, as cool as the ambient. The hottest part is the FTDI FT2232 and MS5351M Clock, at about 40~45 degrees celsius.
And in the second version, I connect the thermal signal to the FPGA reset pin(you can use it in your design), and can stuck your design if it overheated.
