USB UART converter board

I ordered some quick USB UART converter boards I prototyped with QFN28 and QFN24 footprints for the same part. One thing to note that I didn't realize about the QFN24 footprint is that there actually isn't any solder mask in between the pins and the grounding pad like there is on the QFN28, and for both footprints there is not solder mask between the individual pins themselves. Luckily I got the QFN28 part instead of the QFN24, those little buggers are small. Board is manufactured and arrived perfectly and on time. I couldn't find it in the capabilities page, the minimum clearance to have the solder mask go between pads is somewhere between 0.15mm and about 0.25m

    Properly manufactured and good quality PCB, all the component placement was okay and properly soldered.
    Very impressed with the build quality. The fasteners fit like a glove into the threads and countersinks. The plate is even smoother than I expected. It does have visible milling marks (as expected)...
    Quality of the PCB was great. Delivery time very acceptable.
