After waiting a few weeks, the PCBs are now in my possession. I also have all the components I need to build them, even with some self sabotage by ordering the wrong antennas and forgetting to order a coax cable with the parts for Digikey. Firstly we have the radio board:
Initial inspection shows everything to be in order. I should have tented the bottom side of the thermal vias on the antenna board, but its not really a problem. I also should have a bit more imagination when it comes to silkscreens but that doesn't affect anything electrical.
I am very happy with the rounded corners on the PCBs, possibly I should have used a larger radius, but I think all my projects will use rounded corners from this points. Also I would highly recommend having mounding holes all over the place. It the board to be held much more easily, and without the possibility for damage to the board from what is being used to hold it. All you need is to put a bolt through a hole, attack it in place with a nut on the other side and then have something hold the bolt:
For larger boards you might want to do the same thing at the other end of the board to help support it, but even with just one, it is fairly stable.
Next is soldering everything on. I will gloss over this as there are plenty of guides on SMD soldering, and as I'm using neither a stencil or re-flow oven, I'm hardly a good influence. The main points of interest are that I'm glad I changed away from 0201 components that the Nordic design suggested, the USB was much easier to solder than the normal USB-C connectors, and that when soldering QFNs like this it is a good idea to re-flow the solder paste before butting the chip on to make sure there is enough on all the pads. An afternoon later gives me:
