Printed Circuit Boards are the basic components of electronic systems. They are composed of substrate and base materials in the form of a board with copper traces and various components attached to direct current through the circuit. Dotted PCBs v. The components are then attached with wires and soldered together. Designing such PCBs is complex and can have many errors. For example, connecting the pins and avoiding error in shot connections. Layout PCBs, on the other hand, are simpler to design.
It is simpler and has lesser chances of error, and takes lesser time to manufacture. What is Proteus? Proteus is a software used for electronic design automation; mainly used for preparing schematics and designing PCBs. First, run the program by clicking on the icon, and a new splash screen will appear.
Next, a grid-like workspace will appear as shown. There are buttons available that will help us in designing our PCB.
There is a blue rectangle outline; our circuit will be designed within this rectangular space. We will be using Proteus to design the following circuit. It is a 38 kHz frequency generator which uses timer IC. A window will appear. Another way to select components would be to use the toolbar on the left side of your workspace. Now select all the components you require, these will be added to the devices list. The device you select can be rotated by using the rotate buttons. You can then place your component into the workspace.
After placing all your components, place your cursor at the component pin end and draw the connections. Connect all the components to get a designed circuit as shown. If you want to modify any component, simply right click on the component and a dropdown will appear as shown. After completion save and debug the saved file. With this our virtual layout is complete. Proteus has an integrated ARES designing suit. We can use this to develop our PCB. This will open a window with components list.
Now draw a box in your workspace. Our circuit is to be drawn in this box. You can also expand the box if required. Next, click on the component and rotate if required using rotate buttons, then place into your workspace. After adding all the components, arrange the components properly.
Next, connect all the components. Selecting these buttons will open a new window. Select your width according to the PCB you design. Since this is hobbyist PCB made at home, we will use a width greater than Here we will use Next, connect components, click on the component end with pen and follow green line.
If you are designing single layered PCB then components are placed on one side and connections are made on the other side. In double layered, tracking and components are done on two sides. In multi-layered, the different layers are represented by different color.
For example, the bottom layer represents blue, top layer red and inner layers also show different colors. The directions of our component traces are indicated by white arrows, connections by green lines and blue lines show track.
Any errors in tracking are shown by red circles. To avoid errors, you can change the track path. For double layered PCBs, you can change track between layers by double-clicking the left button on your mouse, this will help to change the layer from one to another. The orange circles represent vias between layers. With the auto-router tool, you can arrange the tracks automatically.
You can choose auto-router window will open which contains all the modes, designing rules and grid width options you can change accordingly and then click Routing. Automatic routing will start. Red tracks as shown indicate top and tracks and blue show bottom tracks between layers. This is for double-layered PCBs. After you complete tracking, save your project in the same file you saved your Proteus project.
You can choose 3D visualization o see the final circuit. You can view all the angles, components, board without the components placed, front and back view.
Layout Printing: Next is our final step, layout printing. The print layout window will open. There are many options such as mode, path, scale, rotation etc.
There are 4 modes, artwork, a solder resist, SMT mask and drill plot. In artwork mode, the yellow colored module we designed can be printed. We will take many prints of the circuit layout. Top silk layer prints the components view. PCB Etching: Next, we will move on to the etching process. We will basically design our copper tracks by copper layer print.
Adjust the paper and board carefully. Next, drop the board into the water and remove the paper. The carbon print on the board will remain.
The copper will react with the ferric chloride whereas the copper not having carbon layer will be dissolved. Remove any excess carbon layer. The circuit is complete.
PCB Designing in Proteus ARES
We need 1 resistor of 10k ohm Capacitors. We need 2 capacitors of 33pF Crystal Oscillator. Now in Proteus ARES, select the block option from left toolbar and also make sure that you selected Board Edge in the below drop down menu as shown in below figure: Now make a rectangular block in the workspace, this block is actually the boundary of your PCB. You can set its proper dimensions and can also re-size it manually using the mouse.
