|
| 00.01 | Dear Friends, |
| 00.02 | 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 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 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 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. |
| 08.10 | 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 |
