Sadly, the days of inexpensive PCBs from China are over for US citizens – you all know why so we need not discuss that. The prices from China still beat the prices from US sources in most cases, but even then, there is uncertainty in what the real cost may be with the fluctuating rule changes.
Here are a couple relatively low-cost US options for small boards – these options are based on the area of the board in square inches. As a reminder, area = length × width:
1" × 1" = 1 square inch
2" × 3" = 6 square inches
4" × 4" = 16 square inches (approximate maximum for cheap Chinese options)
These are two sources I have found. Please add any other low cost options you know about.
Please note: these sources are more limited than the Chinese fab houses. Check the space & trace and hole size minimums carefully, and features like internal cutouts may not be available.
