Kicad: create single layer pcb

Flow to create single layer pcb:
  1. Create schematic diagram using Eeschema
  2. Run PvPCB to associate components and footprint
  3. Generate netlist
  4. Run Pcbnew to layout pcb
After running Pcbnew, spread all component with following steps:
  1. Read netlist
  2. Activate Mode footprint: manual and automatic movement and placement
  3. Right click -> Global spread and place
Change default track size and distance
  1. Design Rules -> Design Rules
  2. Set Clearence: default distance between track and other components or track.
  3. Set Track width: default track width/size
Layer setup
  1. Design Rules -> Layers Setup
  2. Set F for front and B for back, with each side F and B.
    1. F: CrtYd, Fab and SilkS
    2. B: Mask, SilkS and Adhes
  • Solder Mask (F/B Mask):These define the solder masks. All pads should appear on one of these layers (SMT) or both (for through hole) to prevent the varnish from covering the pads.
  • Silk Screen (F/B SilkS):They are the layers where the drawings of the components appear. That’s where you draw things like component polarity, first pin indicator, reference for mounting, …
  • Solder Paste (F/B Paste):Used to produce a mask to allow solder paste to be placed on the pads of surface mount components, generally before reflow soldering. Usually only surface mount pads occupy these layers.
  • Adhesive (F/B Adhes):These are used in the application of adhesive to stick SMD components to the circuit board, generally before wave soldering.
  • Fabrication (F/B Fab):Footprint assembly (?).
  • Courtyard (F/B CrtYd):Used to show how much space a component physically takes on the PCB.
