It's been a month since I had ordered PCBA for final prototypes from PCBWay, and finally they are being assembled. I was sent some snaps to verify, overall the board looks good, surprisingly even the silkscreen is decent enough. I still didn't like the HASL finish board, uneven pads are clearly visible, can't blame the manufacturer, the process itself is to blame.

Some components are not soldered, as I have those in excess with me, didn't want to spend money on them when I can solder them at home relatively easily.
