| Time | Narration |
| 00:01 | Dear Friends, Welcome to the spoken tutorial on Designing printed circuit board in KiCad. |
| 00:07 | In this tutorial, we will learn |
| 00:09 | to design printed circuit board in KiCad. |
| 00:12 | We are using Ubuntu 12.04 as the operating system |
| 00:16 | with KiCad version: 2011 hyphen 05 hyphen 25 for this tutorial. |
| 00:25 | Basic knowledge of electronic circuit is a prerequisite for this tutorial. |
| 00:30 | The user should also know: * how to design circuit schematic in KiCad |
| 00:35 | To do electric rule check |
| 00:37 | To do netlist generation |
| 00:39 | To do mapping of components with footprints. |
| 00:43 | For relevant tutorials, please visit:
http://spoken hyphen tutorial.org |
| 00:50 | To start KiCad - |
| 00:52 | Go to the top left corner of Ubuntu desktop screen. |
| 00:56 | Click on the first icon i.e. Dash home. |
| 01:01 | In the search bar, write "KiCad" and press Enter. |
| 01:09 | This will open KiCad main window. |
| 01:12 | To open 'EEschema', go to the top panel and click on EEschema tab. |
| 01:19 | An Info dialog-box will appear which says that it cannot find the schematic. |
| 01:25 | Click on OK. |
| 01:28 | I will use the circuit schematic of Astable multivibrator which was created earlier. |
| 01:35 | To do this, I will go to the File menu, click on Open. |
| 01:42 | Choose the folder in which file is saved. |
| 01:49 | Select 'project1.sch' and click on Open. |
| 01:56 | I will resize the window. |
| 02:00 | So, now I will click on Open. |
| 02:06 | This will open the circuit schematic. |
| 02:08 | I will zoom in using the scroll button of the mouse. |
| 02:13 | We have already generated the netlist for this circuit |
| 02:16 | and done mapping of components with corresponding footprints. |
| 02:20 | The next step is to create the printed circuit board layout. |
| 02:26 | To start with this, click on Run PCBnew button located on the top panel of 'EEschema' window. |
| 02:36 | This will open 'PCBnew' window. |
| 02:39 | An info dialog-box appears saying it did not find 'project1.brd'. |
| 02:44 | Click on OK to close this dialog-box. |
| 02:49 | Now you can import the footprints by clicking on Read netlist button on the top panel of 'PCBnew' window. |
| 02:57 | Here the Netlist window opens. |
| 03:01 | Keep all the default settings as it is. |
| 03:03 | Click on Browse Netlist Files button. |
| 03:07 | This will open Select Netlist window. |
| 03:13 | I will now resize this window for better view. |
| 03:20 | Select project1.net file from desired directory and click on Open. |
| 03:27 | Click on Read Current Netlist button. |
| 03:30 | It will show warning saying 'project1.cmp' not found. |
| 03:35 | Click on OK. |
| 03:37 | Now close Netlist window by clicking on Close button. |
| 03:42 | You can see that all the footprints are imported and placed in the top left corner, in PCBnew window. |
| 03:49 | Now we need to place all footprints in centre of 'PCBnew' window. |
| 03:56 | For this, click on Manual and Automatic move and place of modules button located on the top panel of 'PCBnew' window. |
| 04:08 | Now, right-click once in the centre of the 'PCBnew' window. |
| 04:14 | Go to Glob Move and Place. Then click on Move All Modules. |
| 04:22 | This will open a Confirmation window. Click Yes. |
| 04:28 | I will zoom in with scroll button of my mouse for better view. |
| 04:35 | You may or may not see white wires connecting the terminals of footprints. |
| 04:39 | If you do not see them, click on Show or Hide board ratsnest button located on the left panel of PCBnew window. |
| 04:51 | White wires are also called as airwires. |
| 04:55 | Now we will arrange the modules such that minimum number of airwires cross each other. |
| 05:01 | Now, right-click on IC 555 footprint. |
| 05:07 | Go to Footprint options and click on Move. |
| 05:12 | You can see that the footprint is tied to cursor. |
| 05:16 | You can see that the component moves according to the grid displayed in the background. |
| 05:25 | Now, click once to place the component wherever required. I am going to place it here. |
| 05:33 | It is possible to change the grid spacing using Grid options drop-down menu on the top panel of 'PCBnew' window. |
| 05:44 | For now, we will go ahead with the default value, that is, Grid 1.270. |
| 05:53 | For moving components, you can also use the shortcut key 'M'. |
| 05:58 | For example, let me show you how to move the capacitor. |
| 06:02 | Point the cursor on capacitor. |
| 06:05 | Press 'M'. The module will get tied to cursor. You can move it wherever required. |
| 06:14 | To place component click once. |
| 06:17 | To rotate component, press 'R'. |
| 06:22 | For example, let me rotate the resistor. Place the cursor on the resistor and press 'R'. |
| 06:29 | Similarly, you can arrange all the components. |
| 06:32 | I have already arranged footprints to get minimum intersection between airwires. This is shown here. |
| 06:41 | Now, we need to convert these airwires in to actual tracks. |
| 06:46 | Under the Layer tab on the right side of the 'PCBnew' window, select Back layer, if not selected. Back layer is represented by green colour. |
| 07:01 | Layer selected is pointed by small blue arrow. |
| 07:06 | For creating tracks, select Add tracks and vias button, located on the right panel of 'PCBnew' window. |
| 07:17 | Now, let us click on one of the nodes of 'R1'. |
| 07:22 | Then, we will double-click on node of 'R2' where wire needs to be connected. |
| 07:31 | Similarly, we will connect one more wire between Resistor R3 and capacitor C1. |
| 07:38 | Let us click on one of the nodes of 'R3'. |
| 07:41 | Click once to change direction of wire. |
| 07:46 | Then we will double-click on the node of 'C1' where wire needs to be connected. |
| 07:51 | The green track created represents actual copper path created on the printed circuit board. |
| 07:59 | It is also possible to change the track width. |
| 08:02 | This can be done by clicking on Design Rules menu option in the menu bar of 'PCBnew' window. |
| 08:11 | Click on Design Rules. |
| 08:14 | Design Rules Editor will open where you can change the track width. |
| 08:19 | We will change the track width to 1.5. To do this, double-click on the value of Track Width. Type "1.5" and press Enter. |
| 08:34 | For creating the track, we could also use the 'X 'key on the keyboard. |
| 08:39 | Let me show this to you. Keep the cursor over one of the nodes of LED D1. press the key 'X'. |
| 08:48 | Then, we will double-click on the node of 'R3' where wire needs to be connected. |
| 08:54 | You can see that the width of the track has increased. In this way, you can complete the design of the board. |
| 09:03 | I have already completed the design for this board here. |
| 09:08 | Let me open the completed design board file. |
| 09:19 | We also need to draw the PCB edges for completing this design. |
| 09:25 | For this, we need to select PCB Edges option from Layer tab on the right side of 'PCBnew' window. |
| 09:34 | Now, click on Add graphic line or polygon button located on the right panel of layout editor window. |
| 09:44 | Now, let us create a rectangle around this Printed circuit Board. |
| 09:49 | Click on the top left side of layout. |
| 09:52 | Move the cursor horizontally towards right. |
| 09:56 | Click once to change direction of line. |
| 10:00 | Move the cursor vertically downwards. |
| 10:04 | Similarly, we can complete the rectangle. |
| 10:11 | Let me complete this rectangle. |
| 10:16 | End the rectangle by double-clicking left-mouse-button. |
| 10:24 | Now, let us click on File menu and click on the Save option. Please note that this file is saved with the extension '.brd'. |
| 10:38 | This completes the board layout for Astable multivibrator circuit. |
