Hello Mates, hope you can help me with this problem:
I want to send to print a pcb desing with 2 layers but without any copper in the bottom layer, yes i know i could just choose 1 layer but " Black Mate " solder mask is only available for 2 layers.
So my doubt is, i don't have any track or pads in the bottom layer just the silkscreen, if i export the Gerber file without the " Bottom layer " and without " Bottom paste " what will happen when printing?
1.- will the CNC milling ignore that there is not traces in bottom layer, and copper will stay there intact to later be covered by the solder mask?.
2.- or will the CNC milling remove all the copper, so if you scratch the bottom solder mask won't be conductive?
