I was offered the PCB's along with a soldering paste stencil as sponsorship from PCBWAY. I'm thankfull to them because they help me make these projects by lowering the overall cost.
I ordered the pcbs with black soldermask and with a gold immersion surface finish (ENIG). They came out perfect as far as I can tell, since no shorts or open circuits were made. The soldermask came out great and the silkscreen is perfectly readable.
