manifacturer

• oshpark: 6 dollars per 3 board (5cm x 5cm) - prototype service
  http://docs.oshpark.com/services/
  • i probably order my first board from here.

• macrofab https://macrofab.com/
• seedstudio
• dirtypcb : dirtypcb wants *edge.cuts.gm1 into *.gko extension
• lionscircuits: http://www.lioncircuits.com/ - looks promising for small number for prototypes.

Enable menu icons

On my home PC, the menu icons were absent in kicad somehow. running this command fixes those:

$ gsettings set org.gnome.settings-daemon.plugins.xsettings overrides "{'Gtk/ButtonImages': <1>, 'Gtk/MenuImages': <1>}"

Panelize PCBs

• http://projects.borg.ch/electronics/kicad/panelize.html#A%20Bigger%20Example

• put 2.5-3mm space between each pcb as 1mm space would take up by cutter tool.

Kicad setup guide

first time setup.

1. Setting folders for lib,footprints and 3d shapes.

• create a dir named "Kicad" in ~/repos/

• cd Kicad

• git clone https://github.com/KiCad/kicad-library

• git clone https://github.com/KiCad/kicad-packages3D

• git clone https://github.com/KiCad/kicad-footprints

• open Kicad
  Go to Preferences -> Configure path ->
  KICAD_PTEMPLATES -> /home/ami/repos/KiCad/kicad-library/template
  KIGITHUB -> https://github.com/KiCad
  KISYS3DMOD -> /home/ami/repos/KiCad/kicad-packages3D
  KISYSMOD -> /home/ami/repos/KiCad/kicad-library/modules

• open any sch file and do following things
  Preferences -> component libraries
  delete all components library files click add -> go to /home/ami/repos/KiCad/kicad-library/library and selet all .lib files.

• open any kicad_pcb files and Preferences -> Footprint libraries manager & delete all the libraries
  click append with Wizard -> Files on computer -> Next -> /home/ami/repos/KiCad/kicad-footprints and select all the folders

setting traces size

PCBNew -> Design rules -> Global design tab

Add track1 - 0.1524
track2 - 0.254
track3 - 0.381
track4 - 0.508 track5 - 0.8128

For digital circuits 5v/3.3v, we generally use Track width size 0.381mm

Adding generic Net classes for Power
Click-> Add -> New Net Class Name -> Power ->
Clerance -> 0.25
Track Width -> 0.38
Via Dia -> 0.4
Via Drill -> 0.3
uVia Dia -> 0.3
uVia Drill -> 0.1

Go on left side and select Vcc/5v/3.3v/GND and let them use Power Net Class.
