BackU; main synth_tools/PCB Notes.txt 17 lines Notes from MK's PCB livestream Footprints: - avoid non-circular holes in footprints whenever possible; some fabs charge more for ovals vias connect through the board, adding an extra cross-board wire is needed, vs 3 if the PCB placement. Alternately, pot shafts could be an interesting and useful noisemaker Moar VCFs Everybody needs several VCFs with different behaviors. ** CA3080 design is 1.6mm thick, 2-sided copper clad fiberglass.
