I received my order of PCBs which I ordered in black as they are a front panel, and the boards are only black on the one side (it was the "top" in the layout). Rather disappointing since now I have $100 of useless boards... see images.
When I generated the gerbers and uploaded I did so as a 2 sided board, although there are actually no electrical connections on the back. The system changed it automatically to single-sided, which I presumed was fine.
Questions:
1\. Is it normal for a board to only be coloured black on one side?
2\. Is this a result of something I did or did not do?
3\. Is it a result of the board being changed to single\-sided?
Thanks
